2011-06-28FileCheck-ize a test that had the strangest TCL quote I've seen yet: anChandler Carruth
opening single quote with no closing single quote, and with {} quotes "inside" of it. This broke some of our tools that scrape test cases. Also, while here, make the test actually assert what the comment says it asserts. This was essentially authored by Nick Lewycky, and merely typed in by myself. Let me know if this is still missing the mark, but the previous test only succeeded due to the improper quoting preventing *anything* from matching the grep -- it had a '4(%...)' sequence in the output! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133980 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-27ARM Assembly support for Thumb mov-immediate.Jim Grosbach
Correctly parse the forms of the Thumb mov-immediate instruction: 1. 8-bit immediate 0-255. 2. 12-bit shifted-immediate. The 16-bit immediate "movw" form is also legal with just a "mov" mnemonic, but is not yet supported. More parser logic necessary there due to fixups. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133966 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-27During bottom up fast-isel, instructions emitted to materalize registers are ↵Devang Patel
at top of basic block and do not have debug location. This may misguide debugger while entering the basic block and sometimes debugger provides semi useful view of current location to developer by picking up previous known location as current location. Assign a sensible location to the first instruction in a basic block, if it does not have one location derived from source file, so that debugger can provide meaningful user experience to developers in edge cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133953 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-27pre-RA-sched: Cleanup register pressure tracking.Andrew Trick
Removed the check that peeks past EXTRA_SUBREG, which I don't think makes sense any more. Intead treat it as a normal register def. No significant affect on x86 or ARM benchmarks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133917 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-27Move all inline-asm-fpstack tests to a single file.Jakob Stoklund Olesen
Also fix some of the tests that were actually testing wrong behavior - An input operand in {st} is only popped by the inline asm when {st} is also in the clobber list. The original bug reports all had ~{st} clobbers as they should. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133916 91177308-0d34-0410-b5e6-96231b3b80d8

alloca that only holds a copy of a global and we're going to replace the users of the alloca with that global, just nuke the lifetime intrinsics. Part of PR10121. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133905 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-27Grow the X86FloatingPoint register map to hold 16 registers.Jakob Stoklund Olesen
This allows for more live scratch registers which is needed to handle live ST registers before return and inline asm instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133903 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-27Distinguish early clobber output operands from clobbered registers.Jakob Stoklund Olesen
Both become <earlyclobber> defs on the INLINEASM MachineInstr, but we now use two different asm operand kinds. The new Kind_Clobber is treated identically to the old Kind_RegDefEarlyClobber for now, but x87 floating point stack inline assembly does care about the difference. This will pop a register off the stack: asm("fstp %st" : : "t"(x) : "st"); While this will pop the input and push an output: asm("fst %st" : "=&t"(r) : "t"(x)); We need to know if ST0 was a clobber or an output operand, and we can't depend on <dead> flags for that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133902 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-27Decode and pretty print inline asm operand descriptors.Jakob Stoklund Olesen
The INLINEASM MachineInstrs have an immediate operand describing each original inline asm operand. Decode the bits in MachineInstr::print() so it is easier to read: INLINEASM <es:rorq $1,$0>, $0:[regdef], %vreg0<def>, %vreg1<def>, $1:[imm], 1, $2:[reguse] [tiedto:$0], %vreg2, %vreg3, $3:[regdef-ec], %EFLAGS<earlyclobber,imp-def> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133901 91177308-0d34-0410-b5e6-96231b3b80d8
