Bob Wilson	6b89aa57e6	Revert Anton's most recent EH patch (r96637), since it breaks a lot of ARM and Thumb tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96680 91177308-0d34-0410-b5e6-96231b3b80d8	2010-02-19 17:10:59 +00:00
Duncan Sands	3eba667081	Revert commits 96556 and 96640, because commit 96556 breaks the dragonegg self-host build. I reverted 96640 in order to revert 96556 (96640 goes on top of 96556), but it also looks like with both of them applied the breakage happens even earlier. The symptom of the 96556 miscompile is the following crash: llvm[3]: Compiling AlphaISelLowering.cpp for Release build cc1plus: /home/duncan/tmp/tmp/llvm/lib/CodeGen/SelectionDAG/SelectionDAG.cpp:4982: void llvm::SelectionDAG::ReplaceAllUsesWith(llvm::SDNode, llvm::SDNode, llvm::SelectionDAG::DAGUpdateListener*): Assertion `(!From->hasAnyUseOfValue(i) \|\| From->getValueType(i) == To->getValueType(i)) && "Cannot use this version of ReplaceAllUsesWith!"' failed. Stack dump: 0. Running pass 'X86 DAG->DAG Instruction Selection' on function '@_ZN4llvm19AlphaTargetLowering14LowerOperationENS_7SDValueERNS_12SelectionDAGE' g++: Internal error: Aborted (program cc1plus) This occurs when building LLVM using LLVM built by LLVM (via dragonegg). Probably LLVM has miscompiled itself, though it may have miscompiled GCC and/or dragonegg itself: at this point of the self-host build, all of GCC, LLVM and dragonegg were built using LLVM. Unfortunately this kind of thing is extremely hard to debug, and while I did rummage around a bit I didn't find any smoking guns, aka obviously miscompiled code.

Jim Grosbach	cf43e60544	Radar 7636153. In the presence of large call frames, it's not sufficient for ARM to just check if a function has a FP to determine if it's safe to simplify the stack adjustment pseudo ops prior to eliminating frame indices. Allow targets to override the default behavior and does so for ARM and Thumb2. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96634 91177308-0d34-0410-b5e6-96231b3b80d8	2010-02-19 00:16:24 +00:00
Dan Gohman	1b7bf18def	When determining the set of interesting reuse factors, consider strides in foreign loops. This helps locate reuse opportunities with existing induction variables in foreign loops and reduces the need for inserting new ones. This fixes rdar://7657764. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96629 91177308-0d34-0410-b5e6-96231b3b80d8	2010-02-19 00:05:23 +00:00
Dan Gohman	aa11defd1c	Indvars needs to explicitly notify ScalarEvolution when it is replacing a loop exit value, so that if a loop gets deleted, ScalarEvolution isn't stick holding on to dangling SCEVAddRecExprs for that loop.

Jakob Stoklund Olesen	352d352c02	Always normalize spill weights, also for intervals created by spilling. Moderate the weight given to very small intervals. The spill weight given to new intervals created when spilling was not normalized in the same way as the original spill weights calculated by CalcSpillWeights. That meant that restored registers would tend to hang around because they had a much higher spill weight that unspilled registers. This improves the runtime of a few tests by up to 10%, and there are no significant regressions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96613 91177308-0d34-0410-b5e6-96231b3b80d8	2010-02-18 21:33:05 +00:00

Sanjiv Gupta	e74c3bae3a	Initial implementation of PIC16 Cloner pass. This pass is supposed to be run on the linked .bc module. It traveses the module call graph twice. Once starting from the main function and marking each reached function as "ML". Again, starting from the ISR and cloning any reachable function that was marked as "ML". After cloning the function, it remaps all the call sites in IL functions to call the cloned functions. Currently only marking is being done. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96435 91177308-0d34-0410-b5e6-96231b3b80d8	2010-02-17 01:11:53 +00:00

Evan Cheng	ae3ecf9603	Look for SSE and instructions of this form: (and x, (build_vector c1,c2,c3,c4)). If there exists a use of a build_vector that's the bitwise complement of the mask, then transform the node to (and (xor x, (build_vector -1,-1,-1,-1)), (build_vector ~c1,~c2,~c3,~c4)). Since this transformation is only useful when 1) the given build_vector will become a load from constpool, and 2) (and (xor x -1), y) matches to a single instruction, I decided this is appropriate as a x86 specific transformation. rdar://7323335 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96389 91177308-0d34-0410-b5e6-96231b3b80d8	2010-02-16 21:09:44 +00:00

Jakob Stoklund Olesen	f0907fe590	Enable the inlinehint attribute in the Inliner. Functions explicitly marked inline will get an inlining threshold slightly more aggressive than the default for -O3. This means than -O3 builds are mostly unaffected while -Os builds will be a bit bigger and faster. The difference depends entirely on how many 'inline's are sprinkled on the source. In the CINT2006 suite, only these tests are significantly affected under -Os: Size Time 471.omnetpp +1.63% -1.85% 473.astar +4.01% -6.02% 483.xalancbmk +4.60% 0.00% Note that 483.xalancbmk runs too quickly to give useful timing results. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96066 91177308-0d34-0410-b5e6-96231b3b80d8	2010-02-13 01:51:53 +00:00

Dale Johannesen	c12da8d30a	When save/restoring CR at prolog/epilog, in a large stack frame, the prolog/epilog code was using the same register for the copy of CR and the address of the save slot. Oops. This is fixed here for Darwin, sort of, by reserving R2 for this case. A better way would be to do the store before the decrement of SP, which is safe on Darwin due to the red zone. SVR4 probably has the same problem, but I don't know how to fix it; there is no red zone and R2 is already used for something else. I'm going to leave it to someone interested in that target. Better still would be to rewrite the CR-saving code completely; spilling each CR subregister individually is horrible code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96015 91177308-0d34-0410-b5e6-96231b3b80d8	2010-02-12 21:35:34 +00:00

Chris Lattner	5526b69901	fix a really nasty bug I introduced in r95693: r12 (and r12d, r12b, etc) also encodes to a R/M value of 4, which is just as illegal as ESP/RSP for the non-sib version an address. This fixes x86-64 jit miscompilations of a bunch of programs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95866 91177308-0d34-0410-b5e6-96231b3b80d8	2010-02-11 08:41:21 +00:00

We can now emit fixups like this: subl $20, %esp ## encoding: [0x83,0xec,A] ## fixup A - offset: 2, value: 20, kind: fixup_1byte_imm Emitting $20 as a single-byte fixup to be later resolved by the assembler is ridiculous of course (vs just emitting the byte) but this is a failure of the matcher, which should be producing an imm of 20, not an MCExpr of 20. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95860 91177308-0d34-0410-b5e6-96231b3b80d8	2010-02-11 07:06:31 +00:00

Chris Lattner	8c5ad3a5da	Rename ValueRequiresCast to ShouldOptimizeCast, to better reflect what it does. Enhance it to return false to optimizing vector sign extensions from vector comparisions, which is the idiom used to get a splatted vector for a vector comparison. Doing this breaks vector-casts.ll, add some compensating transformations to handle the important case they cover without depending on this canonicalization. This fixes rdar://7434900 a serious pessimization of vector compares. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95855 91177308-0d34-0410-b5e6-96231b3b80d8	2010-02-11 06:26:33 +00:00
Chris Lattner	98df4f9cf2	Make DSE only scan blocks that are reachable from the entry block. Other blocks may have pointer cycles that will crash basicaa and other alias analyses.

Jeffrey Yasskin	40966a7c68	Make it possible to create multiple JIT instances at the same time, by removing the global TheJIT and TheJITResolver variables.

Mon P Wang	f7ea6c3ee8	The previous fix of widening divides that trap was too fragile as it depends on custom lowering and requires that certain types exist in ValueTypes.h. Modified widening to check if an op can trap and if so, the widening algorithm will apply only the op on the defined elements. It is safer to do this in widening because the optimizer can't guarantee removing unused ops in some cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95823 91177308-0d34-0410-b5e6-96231b3b80d8	2010-02-10 23:37:45 +00:00

These can be created due to type legalization even when the IR-level optimizer has removed dead phis, such as when the high half of an i64 value is unused on a 32-bit target.

Chris Lattner	3484110c67	unify the paths for external symbols and global variables: 2 files changed, 48 insertions(+), 83 deletions(-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95599 91177308-0d34-0410-b5e6-96231b3b80d8	2010-02-08 23:03:41 +00:00
Chris Lattner	8fb2e233a0	switch the rest of the "@ concatentation" logic in the X86 backend to use X86MCTargetExpr, simplifying a bunch of code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95595 91177308-0d34-0410-b5e6-96231b3b80d8	2010-02-08 22:52:47 +00:00
Sean Callanan	3bdbdd06c8	Fixed the AT&T AsmLexer to report the proper strings for register tokens. Before, if it encountered '%al,' it would report 'al,' as the token. Now it correctly reports '%al'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95594 91177308-0d34-0410-b5e6-96231b3b80d8	2010-02-08 22:50:23 +00:00
Chris Lattner	017ec35e28	switch ELF @GOTOFF references to use X86MCTargetExpr. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95593 91177308-0d34-0410-b5e6-96231b3b80d8	2010-02-08 22:33:55 +00:00
Dan Gohman	54e72eca0c	ConstantFoldConstantExpression can theoretically return the original expression; don't go into an infinite loop if it does. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95591 91177308-0d34-0410-b5e6-96231b3b80d8	2010-02-08 22:19:11 +00:00
Chris Lattner	25ceb5f317	add an x86 implementation of MCTargetExpr for representing @GOT and friends. Use it for personality references as a first use. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95588 91177308-0d34-0410-b5e6-96231b3b80d8	2010-02-08 22:09:08 +00:00
Chris Lattner	df9c4380ee	don't make hte dtor private or we can't construct the class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95587 91177308-0d34-0410-b5e6-96231b3b80d8	2010-02-08 22:07:36 +00:00
Johnny Chen	15b423f772	Add VCVTR (between floating-point and integer, VFP) for disassembly purpose. The 'R' suffix means the to-integer operations use the rounding mode specified by the FPSCR, encoded as Inst{7} = 0. A8.6.295 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95584 91177308-0d34-0410-b5e6-96231b3b80d8	2010-02-08 22:02:41 +00:00
Dan Gohman	618f17702d	When CodeGen'ing unoptimized code, there may be unfolded constant expressions in global initializers. Instead of aborting, attempt to fold them on the spot. If folding succeeds, emit the folded expression instead. This fixes PR6255. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95583 91177308-0d34-0410-b5e6-96231b3b80d8	2010-02-08 22:02:38 +00:00
