Nate Begeman 5ca7b345b9 PR 5245 - The imediate size target flag was not set on 3A-prefixed SSSE3 instructions.

Dan Gohman 8f986672a1 Fix SplitBlockPredecessors' LoopInfo updating code to handle the case 
where a loop's header is being split and it has predecessors which are not
contained by the most-nested loop which contains the loop.
This fixes PR5235.

Dan Gohman 511d2e26dd Change instnamer to name arguments "arg" instead of "tmp" for clarity, and 
to name basic blocks "bb" instead of "BB", for consistency.

Torok Edwin 033f01c922 Fix PR5247, "lock addq" pattern (and other atomics), it DOES modify EFLAGS. 
LLC was scheduling compares before the adds causing wrong branches to be taken
in programs, resulting in misoptimized code wherever atomic adds where used.

Evan Cheng 0e9d9ca855 -Revert parts of 84326 and 84411. Distinquishing between fixed and non-fixed 
stack slots and giving them different PseudoSourceValue's did not fix the
problem of post-alloc scheduling miscompiling llvm itself.
- Apply Dan's conservative workaround by assuming any non fixed stack slots can
alias other memory locations. This means a load from spill slot #1 cannot 
move above a store of spill slot #2. 
- Enable post-alloc scheduling for x86 at optimization leverl Default and above.

Nick Lewycky bb1410ea8b Fix test/Bindings/Ocaml/vmcore.ml. When IRBuilder::CreateMalloc was removed, 
LLVMBuildMalloc was reimplemented but with the bug that it didn't insert the
resulting instruction.

Chris Lattner f67d297eda Teach vm core to more aggressively fold 'trunc' constantexprs, 
allowing it to simplify the crazy constantexprs in the testcases
down to something sensible.  This allows -std-compile-opts to
completely "devirtualize" the pointers to member functions in
the testcase from PR5176.

Evan Cheng 0818d87ed1 Rename getFixedStack to getStackObject. The stack objects represented are not 
necessarily fixed. Only those will negative frame indices are "fixed."

Victor Hernandez a3aaf85e23 Remove MallocInst from LLVM Instructions. 
llvm-svn: 84299
 2009-10-17 01:18:07 +00:00
Dan Gohman 0d3d9ee03e Enhance CodePlacementOpt's unconditional intra-loop branch elimination logic 
to be more general and understand more varieties of loops.

Teach CodePlacementOpt to reorganize the basic blocks of a loop so that
they are contiguous. This also includes a fair amount of logic for preserving
fall-through edges while doing so. This fixes a BranchFolding-ism where blocks
which can't be made to use a fall-through edge and don't conveniently fit
anywhere nearby get tossed out to the end of the function.

Victor Hernandez c7d6a8327c Autoupgrade malloc insts to malloc calls. 
Update testcases that rely on malloc insts being present.

Also prematurely remove MallocInst handling from IndMemRemoval and RaiseAllocations to help pass tests in this incremental step.
