2012-08-02X86 Peephole: fold loads to the source register operand if possible.Manman Ren
Add more comments and use early returns to reduce nesting in isLoadFoldable. Also disable folding for V_SET0 to avoid introducing a const pool entry and a const pool load. rdar://10554090 and rdar://11873276 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161207 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-02Add yaml2obj. A utility to convert YAML to binaries.Michael J. Spencer
yaml2obj takes a textual description of an object file in YAML format and outputs the binary equivalent. This greatly simplifies writing tests that take binary object files as input. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161205 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-02X86 Peephole: fold loads to the source register operand if possible.Manman Ren
Machine CSE and other optimizations can remove instructions so folding is possible at peephole while not possible at ISel.

2012-07-31MachineSink: Sort the successors before trying to find SuccToSinkTo.Manman Ren
One motivating example is to sink an instruction from a basic block which has two successors: one outside the loop, the other inside the loop.

Empty macro arguments at the end of the list should be as-if not specified at all, but those in the middle of the list need to be kept so as not to screw up the positional numbering. E.g.: .macro foo foo_-bash___: nop .endm foo 1, 2, 3, 4 foo 1, , 3, 4 Should create two labels, "foo_1_2_3_4" and "foo_1__3_4". rdar://11948769 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161002 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-26Eliminate a batch of uses of sub_ss and sub_sd in the X86 target.Jakob Stoklund Olesen
These idempotent sub-register indices don't do anything --- They simply map XMM registers to themselves. They no longer affect register classes either since the SubRegClasses field has been removed from Target.td. This patch replaces XMM->XMM EXTRACT_SUBREG and INSERT_SUBREG patterns with COPY_TO_REGCLASS patterns which simply become COPY instructions. The number of IMPLICIT_DEF instructions before register allocation is reduced, and that is the cause of the test case changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160816 91177308-0d34-0410-b5e6-96231b3b80d8

It is redundant; RegisterCoalescer will do the remat if it can't eliminate the copy. Collected instruction counts before and after this.
