2009-08-04It helps if I remember to actually add the file...Owen Anderson
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78116 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-04Factor some of the constants+context related code out into a separate ↵Owen Anderson
header, to make LLVMContextImpl.h not hideous. Also, fix some MSVC compile errors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78115 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-04Replace dregsingle operand modifier with explicit escaped curly brackets.Bob Wilson
For other VLDn and VSTn operations, we need to list the multiple registers explicitly anyway, so there's no point in special-casing this one usage. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78109 91177308-0d34-0410-b5e6-96231b3b80d8

This fixes PR4528. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78107 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-04Don't give implicit machine operands special treatment in the register ↵Jakob Stoklund Olesen
scavenger. Imp-def is *not* allowed to redefine a live register. Imp-use is *not* allowed to use a dead register. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78106 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-04Add NEON single-precision FP support for fabs and fneg.David Goodwin
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78101 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-04When exec() fails, return 127 instead of errno; the parent process has no way toDaniel Dunbar
distinguish that the result is errno, so it can't use it to provide more information about the error (it also exposes the numeric value of errno). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78098 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78097 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-04rip out SectionEndDirectiveSuffix support, only uses byChris Lattner
the masm backend. If anyone cares about masm in the future, we'll have semantic sections it can hang off of. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78096 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-04Don't tamper with <undef> operands in MachineInstr::addRegisterKilled.Jakob Stoklund Olesen
For an undef operand, MO.getReg() is meaningless and we should not use it. Undef operands should be skipped entirely. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78095 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-04LowerSubregsInstructionPass::LowerExtract should not extend the live range ↵Jakob Stoklund Olesen
of registers. When LowerExtract eliminates an EXTRACT_SUBREG with a kill flag, it moves the kill flag to the place where the sub-register is killed. This can accidentally overlap with the use of a sibling sub-register, and we have trouble. In the test case we have this code: Live Ins: %R0 %R1 %R2 %R2L<def> = EXTRACT_SUBREG %R2<kill>, 1 %R2H<def> = LOAD16fi <fi#-1>, 0, Mem:LD(2,4) [FixedStack-1 + 0] %R1L<def> = EXTRACT_SUBREG %R1<kill>, 1 %R0L<def> = EXTRACT_SUBREG %R0<kill>, 1 %R0H<def> = ADD16 %R2H<kill>, %R2L<kill>, %AZ<imp-def>, %AN<imp-def>, %AC0<imp-def>, %V<imp-def>, %VS<imp-def> subreg: CONVERTING: %R2L<def> = EXTRACT_SUBREG %R2<kill>, 1 subreg: eliminated! subreg: killed here: %R0H<def> = ADD16 %R2H, %R2L, %R2<imp-use,kill>, %AZ<imp-def>, %AN<imp-def>, %AC0<imp-def>, %V<imp-def>, %VS<imp-def> The kill flag on %R2 is moved to the last instruction, and the live range overlaps with the definition of %R2H: *** Bad machine code: Redefining a live physical register *** - function: f - basic block: 0x18358c0 (#0) - instruction: %R2H<def> = LOAD16fi <fi#-1>, 0, Mem:LD(2,4) [FixedStack-1 + 0] Register R2H was defined but already live. The fix is to replace EXTRACT_SUBREG with IMPLICIT_DEF instead of eliminating it completely: subreg: CONVERTING: %R2L<def> = EXTRACT_SUBREG %R2<kill>, 1 subreg: replace by: %R2L<def> = IMPLICIT_DEF %R2<kill> Note that these IMPLICIT_DEF instructions survive to the asm output. It is necessary to fix the stack-color-with-reg test case because of that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78093 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-04Enforce stricter rules in machine code verifier.Jakob Stoklund Olesen
Implicit operands no longer get a free pass: Imp-use requires a live register and imp-def requires a dead register. There is also no special rule allowing redefinition of a sub-register when the super-register is live. The super register must have imp-kill+imp-def operands instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78090 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-04Fix PR4528. This scavenger assertion is too strict. The two-address value isEvan Cheng
killed by another operand. There is probably a better fix. Either 1) scavenger can look at other operands, or 2) livevariables can be smarter about kill markers. Patches welcome. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78072 91177308-0d34-0410-b5e6-96231b3b80d8
