Evan Cheng	6784598895	Fix a very subtle spiller bug: UpdateKills should not forget to track defs of aliases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57673 91177308-0d34-0410-b5e6-96231b3b80d8	2008-10-17 06:16:07 +00:00
Dan Gohman	74feef261a	Define patterns for shld and shrd that match immediate shift counts, and patterns that match dynamic shift counts when the subtract is obscured by a truncate node. Add DAGCombiner support for recognizing rotate patterns when the shift counts are defined by truncate nodes. Fix and simplify the code for commuting shld and shrd instructions to work even when the given instruction doesn't have a parent, and when the caller needs a new instruction. These changes allow LLVM to use the shld, shrd, rol, and ror instructions on x86 to replace equivalent code using two shifts and an or in many more cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57662 91177308-0d34-0410-b5e6-96231b3b80d8	2008-10-17 01:23:35 +00:00
Dan Gohman	131161bc6e	Rename AliasSet to SubRegs, to reflect changes in the surrounding code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57618 91177308-0d34-0410-b5e6-96231b3b80d8	2008-10-16 01:06:18 +00:00
Dan Gohman	7ddcadc7ee	Move the include of MachineLocation.h into MachineModuleInfo.h because it declares a std::vector<MachineMove>, and strict concept checking requires the definition of MachineMove to be available. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57617 91177308-0d34-0410-b5e6-96231b3b80d8	2008-10-16 00:20:14 +00:00
Dan Gohman	b382c4dc23	Fix a subtle bug in DeadMachineInstructionElim's liveness computation. A def of a register doesn't necessarily kill live super-registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57614 91177308-0d34-0410-b5e6-96231b3b80d8	2008-10-16 00:11:23 +00:00
Dan Gohman	26367472a2	Adjust whitespace in debug messages to be more consistent with other debug messages. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57543 91177308-0d34-0410-b5e6-96231b3b80d8	2008-10-15 02:57:38 +00:00
Evan Cheng	7f04268176	- Add target lowering hooks that specify which setcc conditions are illegal, i.e. conditions that cannot be checked with a single instruction. For example, SETONE and SETUEQ on x86. - Teach legalizer to implement illegal setcc as a and / or of a number of legal setcc nodes. For now, only implement FP conditions. e.g. SETONE is implemented as SETO & SETNE, SETUEQ is SETUO \| SETEQ. - Move x86 target over. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57542 91177308-0d34-0410-b5e6-96231b3b80d8	2008-10-15 02:05:31 +00:00
Dan Gohman	dd5b58ad7b	FastISel support for exception-handling constructs. - Move the EH landing-pad code and adjust it so that it works with FastISel as well as with SDISel. - Add FastISel support for @llvm.eh.exception and @llvm.eh.selector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57539 91177308-0d34-0410-b5e6-96231b3b80d8	2008-10-14 23:54:11 +00:00

Dan Gohman	b8cab9227a	Fix command-line option printing to print two spaces where needed, instead of requiring all "short description" strings to begin with two spaces. This makes these strings less mysterious, and it fixes some cases where short description strings mistakenly did not begin with two spaces. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57521 91177308-0d34-0410-b5e6-96231b3b80d8	2008-10-14 20:25:08 +00:00

Matthijs Kooijman	d9d07780ff	* Make TargetLowering not crash when TargetMachine::getTargetAsmInfo() returns null. This assumes that any target that does not have AsmInfo, does not support "LocAndDot". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57438 91177308-0d34-0410-b5e6-96231b3b80d8	2008-10-13 12:41:46 +00:00
Matthijs Kooijman	e2b997b7b5	Make MachineFunction not crash when TargetMachine::getRegisterInfo() returns NULL, but just hide some debug output then. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57437 91177308-0d34-0410-b5e6-96231b3b80d8	2008-10-13 12:37:16 +00:00

Chris Lattner	e563bbc312	Change CALLSEQ_BEGIN and CALLSEQ_END to take TargetConstant's as parameters instead of raw Constants. This prevents the constants from being selected by the isel pass, fixing PR2735. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57385 91177308-0d34-0410-b5e6-96231b3b80d8	2008-10-11 22:08:30 +00:00

Adjust all users accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57329 91177308-0d34-0410-b5e6-96231b3b80d8	2008-10-09 23:00:39 +00:00
Dale Johannesen	7111b02c73	Rename APFloat::convertToAPInt to bitcastToAPInt to make it clearer what the function does. No functional change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57325 91177308-0d34-0410-b5e6-96231b3b80d8	2008-10-09 18:53:47 +00:00

Dan Gohman	eb0d6abee3	Remove -disable-fast-isel. Use cl::boolOrDefault with -fast-isel instead. So now: -fast-isel or -fast-isel=true enable fast-isel, and -fast-isel=false disables it. Fast-isel is also on by default with -fast, and off by default otherwise. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57270 91177308-0d34-0410-b5e6-96231b3b80d8	2008-10-07 23:00:56 +00:00
Dan Gohman	1e9e8c3bd5	Avoid emitting redundant materializations of integer constants for things like null pointers, which at this level aren't different from regular integer constants. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57265 91177308-0d34-0410-b5e6-96231b3b80d8	2008-10-07 22:03:27 +00:00

Dan Gohman	241f464d24	Fix fast-isel's handling of atomic instructions. They may expand to multiple basic blocks, in which case fast-isel needs to informed of which block to use as it resumes inserting instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57040 91177308-0d34-0410-b5e6-96231b3b80d8	2008-10-04 00:56:36 +00:00
Dan Gohman	022b21ff7c	Fix a bug in the local allocator's liveness computation where it was setting kill flags on tied uses in two-address instructions. The kill flags were causing the allocator to think it could allocate the use and its tied def in different registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57039 91177308-0d34-0410-b5e6-96231b3b80d8	2008-10-04 00:31:14 +00:00

Duncan Sands	e47561ccff	The result of getSetCCResultType (eg: i32) may be larger than the type an i1 is promoted to (eg: i8). Account for this. Noticed by Tilmann Scheller on CellSPU; he will hopefully take care of fixing this in LegalizeDAG and adding a testcase! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56997 91177308-0d34-0410-b5e6-96231b3b80d8	2008-10-03 07:41:46 +00:00
Dan Gohman	91b6f97ce4	Implement fast-isel support for zero-extending from i1. It turns out that this is a fairly common operation, and it's easy enough to handle. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56990 91177308-0d34-0410-b5e6-96231b3b80d8	2008-10-03 01:28:47 +00:00

Owen Anderson	8481ee7f52	Use a multimap rather than a map for holding the list of copies to insert, so we don't lose copies when two of them have the same source. I don't know what I was thinking when I wrote this originally. Note: There's probably a more efficient way to do this, but I need to think about it some more, and about what determinism guarantees need to be present. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56964 91177308-0d34-0410-b5e6-96231b3b80d8	2008-10-02 19:40:33 +00:00

Bill Wendling	6f287b22d2	Add the new `-no-builtin' flag. This flag is meant to mimic the GCC `-fno-builtin' flag.

Dan Gohman	f06c835f76	Optimize SelectionDAG's AssignTopologicalOrder even further. Completely eliminate the TopOrder std::vector. Instead, sort the AllNodes list in place. This also eliminates the need to call AllNodes.size(), a linear-time operation, before performing the sort. Also, eliminate the Sources temporary std::vector, since it essentially duplicates the sorted result as it is being built. This also changes the direction of the topological sort from bottom-up to top-down. The AllNodes list starts out in roughly top-down order, so this reduces the amount of reordering needed. Top-down is also more convenient for Legalize, and ISel needed only minor adjustments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56867 91177308-0d34-0410-b5e6-96231b3b80d8	2008-09-30 18:30:35 +00:00

Bill Wendling	d751c64a67	If we have a function with an unreachable statement such that the ending debug information is in an unreachable block, then it's possible that the high/low pc values won't be set for the dwarf information. E.g., this function: void abort(void) __attribute__((__noreturn__)); void dead_beef(void) __attribute__ ((noreturn)); int b; void dead_beef(void) { b=0xdeadbeef; abort(); } has a call to "@llvm.dbg.region.end" only in the unreachable block: define void @dead_beef() noreturn nounwind { entry: call void @llvm.dbg.func.start(...) call void @llvm.dbg.stoppoint(...) ... call void @abort( ) noreturn nounwind unreachable return: ; No predecessors! call void @llvm.dbg.stoppoint(...) call void @llvm.dbg.region.end(...) ret void } The dwarf information emitted is something like: 0x00000084: TAG_subprogram [5] AT_name( "dead_beef" ) AT_external( 0x01 ) AT_prototyped( 0x01 ) AT_decl_file( 0x01 ) AT_decl_line( 0x08 ) Note that this is not the best fix for this problem, but a band-aid for an gaping wound.

Dan Gohman	ee2e403545	Add a new "fast" scheduler. This is currently basically just a copy of the BURRList scheduler, but with several parts ripped out, such as backtracking, online topological sort maintenance (needed by backtracking), the priority queue, and Sethi-Ullman number computation and maintenance (needed by the priority queue). As a result of all this, it generates somewhat lower quality code, but that's its tradeoff for running about 30% faster than list-burr in -fast mode in many cases. This is somewhat experimental. Moving forward, major pieces of this can be refactored with pieces in common with ScheduleDAGRRList.cpp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56307 91177308-0d34-0410-b5e6-96231b3b80d8	2008-09-18 16:26:26 +00:00

Evan Cheng	1cd332725f	When converting a CopyFromReg to a copy instruction, use the register class of its uses to determine the right destination register class of the copy.

Dan Gohman	50284d81f8	Change SelectionDAG::getConstantPool to always set the alignment of the ConstantPoolSDNode, using the target's preferred alignment for the constant type. In LegalizeDAG, when performing loads from the constant pool, the ConstantPoolSDNode's alignment is used in the calls to getLoad and getExtLoad. This change prevents SelectionDAG::getLoad/getExtLoad from incorrectly choosing the ABI alignment for constant pool loads when Alignment == 0. The incorrect alignment is only a performance issue when ABI alignment does not equal preferred alignment (i.e., on x86 it was generating MOVUPS instead of MOVAPS for v4f32 constant loads when the default ABI alignment for 128bit vectors is forced to 1 byte.)

Dan Gohman	4fbd796a12	Change ConstantSDNode and ConstantFPSDNode to use ConstantInt* and ConstantFP* instead of APInt and APFloat directly. This reduces the amount of time to create ConstantSDNode and ConstantFPSDNode nodes when ConstantInt* and ConstantFP* respectively are already available, as is the case in SelectionDAGBuild.cpp. Also, it reduces the amount of time to legalize constants into constant pools, and the amount of time to add ConstantFP operands to MachineInstrs, due to eliminating ConstantInt::get and ConstantFP::get calls. It increases the amount of work needed to create new constants in cases where the client doesn't already have a ConstantInt* or ConstantFP*, such as legalize expanding 64-bit integer constants to 32-bit constants. And it adds a layer of indirection for the accessor methods. But these appear to be outweight by the benefits in most cases. It will also make it easier to make ConstantSDNode and ConstantFPNode more consistent with ConstantInt and ConstantFP. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56162 91177308-0d34-0410-b5e6-96231b3b80d8	2008-09-12 18:08:03 +00:00

Owen Anderson	369e98760b	Fix a bug in the coalescer where it didn't check if a live interval existed before trying to manipulate it. This was exposed by fast isel's handling of shifts on X86-64. With this, FreeBench/pcompress2 passes on X86-64 in fast isel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56067 91177308-0d34-0410-b5e6-96231b3b80d8	2008-09-10 20:41:13 +00:00

Bill Wendling	aeb5c7b353	Implement "visitPow". This is mainly used to see if we have a pow() call of this form: powf(10.0f, x); If this is the case, and also we want limited precision floating-point calculations, then lower to do the limited-precision stuff. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56035 91177308-0d34-0410-b5e6-96231b3b80d8	2008-09-10 00:20:20 +00:00

Dan Gohman	4344a5d0d7	Change -fast-isel-no-abort to -fast-isel-abort, which now defaults to being off by default. Also, add assertion checks to check that the various fast-isel-related command-line options are only used when -fast-isel itself is enabled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56029 91177308-0d34-0410-b5e6-96231b3b80d8	2008-09-09 23:05:00 +00:00

Dale Johannesen	d2e51af035	Move the uglier parts of deciding not to emit a UsedDirective for some symbols in llvm.used into Darwin-specific code. I've decided LessPrivateGlobal is potentially a useful abstraction and left it in the target-independent area, with improved comment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56024 91177308-0d34-0410-b5e6-96231b3b80d8	2008-09-09 22:29:13 +00:00

Dan Gohman	cf01f7a78c	Remove the code that protected FastISel from aborting in the case of loads, stores, and conditional branches. It can handle those now, so any that aren't handled should trigger the abort. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55977 91177308-0d34-0410-b5e6-96231b3b80d8	2008-09-09 02:40:04 +00:00

Dale Johannesen	b2dfb89e0e	Fix logic for not emitting no-dead-strip for some objects in llvm.used (thanks Anton). Makes visible the magic 'l' prefix for symbols on Darwin which are to be passed through the assembler, then removed at linktime (previously all references to this had been hidden in the ObjC FE code, oh well). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55973 91177308-0d34-0410-b5e6-96231b3b80d8	2008-09-09 01:21:22 +00:00

Dan Gohman	be0034e3c2	Revert r55817. It broke PIC. FastISel will need to find a different approach here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55842 91177308-0d34-0410-b5e6-96231b3b80d8	2008-09-05 18:13:01 +00:00

Dan Gohman	c7f4a8a80c	In FastISel mode, the scheduler may be invoked multiple times in the same block. Fix the entry-block handling to only run at at the beginning of the entry block, and not any other times. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55817 91177308-0d34-0410-b5e6-96231b3b80d8	2008-09-05 01:07:48 +00:00
Owen Anderson	95267a1e67	Add initial support for selecting constant materializations that require constant pool loads on X86 in fast isel. This isn't actually used yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55814 91177308-0d34-0410-b5e6-96231b3b80d8	2008-09-05 00:06:23 +00:00

Evan Cheng	90960280ee	Fix an overly strict assertion. Source register of a copy may not be killed, it may be killed by an implicit super-register use. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55762 91177308-0d34-0410-b5e6-96231b3b80d8	2008-09-04 05:43:55 +00:00
Dale Johannesen	7794f2a3a7	Add intrinsics for log, log2, log10, exp, exp2. No functional change (and no FE change to generate them). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55753 91177308-0d34-0410-b5e6-96231b3b80d8	2008-09-04 00:47:13 +00:00

Dan Gohman	3df24e667f	Create HandlePHINodesInSuccessorBlocksFast, a version of HandlePHINodesInSuccessorBlocks that works FastISel-style. This allows PHI nodes to be updated correctly while using FastISel. This also involves some code reorganization; ValueMap and MBBMap are now members of the FastISel class, so they needn't be passed around explicitly anymore. Also, SelectInstructions is changed to SelectInstruction, and only does one instruction at a time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55746 91177308-0d34-0410-b5e6-96231b3b80d8	2008-09-03 23:12:08 +00:00
Dale Johannesen	61e6093dc8	Do not emit a UsedDirective for things in the llvm.used list that have internal linkage; the linker doesn't need or want this.

Owen Anderson	99aaf108cd	Fix an issue where we were reusing materializations of constants in blocks not dominated by the materialization. This is the simple fix, materializing the constant before every use. It might be better to either track domination of uses or to materialize all constants and the beginning of the function and let remat sort when to do materialization at uses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55703 91177308-0d34-0410-b5e6-96231b3b80d8	2008-09-03 17:37:03 +00:00

Dan Gohman	3f62940561	Fix addRegisterDead and addRegisterKilled to be more thorough when searching for redundant subregister dead/kill bits. Previously it was common to see instructions marked like this: "RET %EAX<imp-use,kill>, %AX<imp-use,kill>" With this change, addRegisterKilled continues scanning after finding the %EAX operand, so it proceeds to discover the redundant %AX kill and eliminates it, producing this: "RET %EAX<imp-use,kill>" This currently has no effect on the generated code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55698 91177308-0d34-0410-b5e6-96231b3b80d8	2008-09-03 15:56:16 +00:00

Gabor Greif	ed63214fcb	Provide two overloads of AnalyzeNewNode. The first can update the SDNode in an SDValue while the second is called with SDNode* and returns a possibly updated SDNode*. This patch has no intended functional impact, but helps eliminating ugly temporary SDValues. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55608 91177308-0d34-0410-b5e6-96231b3b80d8	2008-09-01 15:10:19 +00:00

Owen Anderson	cc54e76cc6	Fix an issue where a use might be selected before a def, and then we didn't respect the pre-chosen vreg assignment when selecting the def. This is the naive solution to the problem: insert a copy to the pre-chosen vreg. Other solutions might be preferable, such as: 1) Passing the dest reg into FastEmit_. However, this would require the higher level code to know about reg classes, which they don't currently. 2) Selecting blocks in reverse postorder. This has some compile time cost for computing the order, and we'd need to measure its impact. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55555 91177308-0d34-0410-b5e6-96231b3b80d8	2008-08-30 00:38:46 +00:00

Dan Gohman	a3f8b7a4ce	Optimize DAGCombiner's worklist processing. Previously it started its work by putting all nodes in the worklist, requiring a big dynamic allocation. Now, DAGCombiner just iterates over the AllNodes list and maintains a worklist for nodes that are newly created or need to be revisited. This allows the worklist to stay small in most cases, so it can be a SmallVector. This has the side effect of making DAGCombine not miss a folding opportunity in alloca-align-rounding.ll. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55498 91177308-0d34-0410-b5e6-96231b3b80d8	2008-08-28 21:01:56 +00:00

Dale Johannesen	e00a8a2a2e	Split the ATOMIC NodeType's to include the size, e.g. ATOMIC_LOAD_ADD_{8,16,32,64} instead of ATOMIC_LOAD_ADD. Increased the Hardcoded Constant OpActionsCapacity to match. Large but boring; no functional change. This is to support partial-word atomics on ppc; i8 is not a valid type there, so by the time we get to lowering, the ATOMIC_LOAD nodes looks the same whether the type was i8 or i32. The information can be added to the AtomicSDNode, but that is the largest SDNode; I don't fully understand the SDNode allocation, but it is sensitive to the largest node size, so increasing that must be bad. This is the alternative. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55457 91177308-0d34-0410-b5e6-96231b3b80d8	2008-08-28 02:44:49 +00:00
Dan Gohman	7c3234c6be	Reorganize the lifetimes of the major objects SelectionDAGISel works with. SelectionDAG, FunctionLoweringInfo, and SelectionDAGLowering objects now get created once per SelectionDAGISel instance, and can be reused across blocks and across functions. Previously, they were created and destroyed each time they were needed. This reorganization simplifies the handling of PHI nodes, and also SwitchCases, JumpTables, and BitTestBlocks. This simplification has the side effect of fixing a bug in FastISel where successor PHI nodes weren't being updated correctly. This is also a step towards making the transition from FastISel into and out of SelectionDAG faster, and also making plain SelectionDAG faster on code with lots of little blocks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55450 91177308-0d34-0410-b5e6-96231b3b80d8	2008-08-27 23:52:12 +00:00

Chris Lattner	944fac71e0	Switch the asmprinter (.ll) and all the stuff it requires over to use raw_ostream instead of std::ostream. Among other goodness, this speeds up llvm-dis of kc++ with a release build from 0.85s to 0.49s (88% faster). Other interesting changes: 1) This makes Value::print be non-virtual. 2) AP[S]Int and ConstantRange can no longer print to ostream directly, use raw_ostream instead. 3) This fixes a bug in raw_os_ostream where it didn't flush itself when destroyed. 4) This adds a new SDNode::print method, instead of only allowing "dump". A lot of APIs have both std::ostream and raw_ostream versions, it would be useful to go through and systematically anihilate the std::ostream versions. This passes dejagnu, but there may be minor fallout, plz let me know if so and I'll fix it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55263 91177308-0d34-0410-b5e6-96231b3b80d8	2008-08-23 22:23:09 +00:00

Dan Gohman	f350b277f3	Move the point at which FastISel taps into the SelectionDAGISel process up to a higher level. This allows FastISel to leverage more of SelectionDAGISel's infastructure, such as updating Machine PHI nodes. Also, implement transitioning from SDISel back to FastISel in the middle of a block, so it's now possible to go back and forth. This allows FastISel to hand individual CallInsts and other complicated things off to SDISel to handle, while handling the rest of the block itself. To help support this, reorganize the SelectionDAG class so that it is allocated once and reused throughout a function, instead of being completely reallocated for each block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55219 91177308-0d34-0410-b5e6-96231b3b80d8	2008-08-23 02:25:05 +00:00
