Chris Lattner	43a5ff8d40	Emit x86 instructions for: A = B op C, where A and B are 16-bit registers, ... C is a constant which can be sign-extended from 8 bits without value loss, and op is one of: add, sub, imul, and, or, xor. This allows the JIT to emit the one byte version of the constant instead of the two or 4 byte version. Because these instructions are very common, this can save a LOT of code space. For example, I sampled two benchmarks, 176.gcc and 254.gap. BM Old New Reduction 176.gcc 2673621 2548962 4.89% 254.gap 498261 475104 4.87% Note that while the percentage is not spectacular, this did eliminate 124.6 _KILOBYTES_ of codespace from gcc. Not bad.

Chris Lattner	927b185c17	Major refactoring of the bytecode reader. This includes the following ... changes: * BytecodeReader::getType(...) used to return a null pointer on error.

This was checked in before, but psmith crashed and lost the change :( * insertValue no longer returns -1 on error, so callers don't need to check for it. * Substantial rewrite of InstructionReader.cpp, to use more efficient, simpler, data structures.

This simple change improves the performance of loading a file from HDF5 (contributed by Bill) from 2.36s to 1.93s, a 22% improvement.

Chris Lattner	884d6c4e10	Speed up the predicate used to decide when to inline by caching the size ... of callees between executions. On eon, in release mode, this changes the inliner from taking 11.5712s to taking 2.2066s. In debug mode, it went from taking 14.4148s to taking 7.0745s. In release mode, this is a 24.7% speedup of gccas, in debug mode, it's a total speedup of 11.7%. This also makes it slightly more aggressive. This could be because we are not judging the size of the functions quite as accurately as before. When we start looking at the performance of the generated code, this can be investigated further. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8893 91177308-0d34-0410-b5e6-96231b3b80d8	2003-10-06 15:52:43 +00:00

Chris Lattner	69091be83b	This changes the PromoteMemToReg function to create "pruned" SSA form, not ... "minimal" SSA form (in other words, it doesn't insert dead PHIs). This speeds up the mem2reg pass very significantly because it doesn't have to do a lot of frivolous work in many common cases. In the 252.eon function I have been playing with, this doesn't even insert the 120 PHI nodes that it used to which were trivially dead (in the process of promoting 356 alloca instructions overall). This speeds up the mem2reg pass from 1.2459s to 0.1284s. More significantly, the DCE pass used to take 2.4138s to remove the 120 dead PHI nodes that mem2reg constructed, now it takes 0.0134s (which is the time to scan the function and decide that there is nothing dead). So overall, on this one function, we speed things up a total of 3.5179s, which is a 24.8x speedup! :) This change is tested by the Mem2Reg/2003-10-05-DeadPHIInsertion.ll test, which now passes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8884 91177308-0d34-0410-b5e6-96231b3b80d8	2003-10-05 22:19:20 +00:00

Chris Lattner	24011be956	Speed up the mem2reg transform for allocas which are only read/written in a single ... basic block. This is amazingly common in code generated by the C/C++ front-ends. This change makes it not have to insert ANY phi nodes, whereas before it would insert a ton of dead ones which DCE would have to clean up. Thus, this fix improves compile-time performance of these trivial allocas in two ways: 1. It doesn't have to do the walking and book-keeping for renaming 2. It does not insert dead phi nodes for them which would have to subsequently be cleaned up. On my favorite testcase from 252.eon, this special case handles 305 out of 356 promoted allocas in the function. It speeds up the mem2reg pass from 7.5256s to 1.2505s. It inserts 677 fewer dead PHI nodes, which speeds up a subsequent -dce pass from 18.7524s to 2.4806s. There are still 120 trivially dead PHI nodes being inserted for variables used in multiple basic blocks, but they are not handled by this patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8881 91177308-0d34-0410-b5e6-96231b3b80d8	2003-10-05 20:54:03 +00:00

Chris Lattner	7685ac8d35	This checkin basically amounts to a complete rewrite of the type-resolution ... machinery. This dramatically simplifies how things works, removes irritating little corner cases, and overall improves speed and reliability. Highlights of this change are: 1. The exponential algorithm built into the code is now gone. For example the time to disassemble one bytecode file from the mesa benchmark went from taking 12.5s to taking 0.16s. 2. The linker bugs should be dramatically reduced. The one remaining bug has to do with constant handling, which I actually introduced in "union-find" checkins. 3. The code is much easier to follow, as a result of fewer special cases.

Chris Lattner	8ef852f4ea	Dramatically simplify DerivedType::refineAbstractTypeToInternal ... This makes use of the new PATypeHolder's to keep types from being deleted prematurely, instead of the wierd "self reference" garbage. This is easier to understand and more efficient as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8834 91177308-0d34-0410-b5e6-96231b3b80d8	2003-10-03 04:48:21 +00:00
Chris Lattner	1c5164e9cf	Make the PATypeHolder use a simple union-find implementation to handle ... merging of types. This makes it MUCH more efficient than before, also making things simpler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8833 91177308-0d34-0410-b5e6-96231b3b80d8	2003-10-02 23:35:57 +00:00
Chris Lattner	c7b6f03501	There is no need for BytecodeParser to be an AbstractTypeUser. Instead, it ... can just use PATypeHolders git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8832 91177308-0d34-0410-b5e6-96231b3b80d8	2003-10-02 20:26:18 +00:00
Chris Lattner	3200219843	There is no reason for Value to be an AbstractTypeUser. This just makes things ... significantly more complete. Instead, just make DerivedType's AbstractTypeUser's, and make Value contain a PATypeHolder. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8828 91177308-0d34-0410-b5e6-96231b3b80d8	2003-10-02 19:44:40 +00:00
