2012-08-24Remove some spurious mayLoad = 0 flags.Jakob Stoklund Olesen
They were inserted to silence TableGen's warning about redundant properties. That warning is now gone. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162517 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-23Remove the llvm.nacl.thread.stack.padding intrinsicMark Seaborn
This intrinsic is no longer used by untrusted code's libpthread. Instead the system (the IRT and/or TCB) is responsible for aligning the stack in new threads.

2012-08-23Make function loadImmediate a member of MipsSEInstrInfo and change it to returnAkira Hatanaka
the temporary register that was used to load the immediate. Currently, it always returns register $at, but this will change if, in the future, we decide to use another register. No changes in functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162417 91177308-0d34-0410-b5e6-96231b3b80d8

Mips16RegisterInfo/MipsSERegisterInfo. No changes in functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162413 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-22[ms-inline asm] Avoid a false positive assertionChad Rosier
Assertion failed: (Start.isValid() == End.isValid() && "Start and end should either both be valid or both be invalid!") when parsing inline asm. SMLoc assumes that the first char * in the source is invalid. However, when parsing an inline asm the mnemonic is at this location. I don't want to change SMLoc, so use a trivial workaround. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162381 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-22Add a getName function to MachineFunction. Use it in places that previously ↵Craig Topper
did getFunction()->getName(). Remove includes of Function.h that are no longer needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162347 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-22Don't cache the MBB in the class. Its only used by one function. Change a ↵Craig Topper
for loop over operands to use unsigned instead of int. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162344 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162342 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-22Add register Mips::GP to the list of reserved registers if target is bare-metalAkira Hatanaka
to prevent it from being clobbered. mips uses $gp to access small data section. This bug was originally reported by Carl Norum. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162340 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-22Add option disable-mips-delay-filler. Turn on mips' delay slot filler byAkira Hatanaka
default. Patch by Carl Norum. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162339 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-22For mips64 switch statements in subroutines could generate Jack Carter
within the codegen EK_GPRel64BlockAddress. This was not supported for direct object output and resulted in an assertion. This change adds support for EK_GPRel64BlockAddress for direct object. One fallout from this is to turn on rela relocations for mips64 to match gas. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162334 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-21[ms-inline asm] Do not report a Parser error when matching inline assembly.Chad Rosier
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162306 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-21[ms-inline asm] Expose the ErrorInfo from the MatchInstructionImpl. In general,Chad Rosier
this is the index of the operand that failed to match. Note: This may cause a buildbot failure due to an API mismatch in clang. Should recover with my next commit to clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162295 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-19When unsafe math is used, we can use commutative FMAX and FMIN. In some casesNadav Rotem
this allows for better code generation. Added a new DAGCombine transformation to convert FMAX and FMIN to FMANC and FMINC, which are commutative. For example: movaps %xmm0, %xmm1 movsd LC(%rip), %xmm0 minsd %xmm1, %xmm0 becomes: minsd LC(%rip), %xmm0 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162187 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-18Remove the CAND/COR/CXOR custom ISD nodes and their select code.Jakob Stoklund Olesen
These nodes are no longer needed because the peephole pass can fold CMOV+AND into ANDCC etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162179 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-18Remove virtual from many methods. These methods replace methods in the base ↵Craig Topper
class, but the base class methods aren't virtual so it just increased call overhead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162178 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-18Also combine zext/sext into selects for ARM.Jakob Stoklund Olesen
This turns common i1 patterns into predicated instructions: (add (zext cc), x) -> (select cc (add x, 1), x) (add (sext cc), x) -> (select cc (add x, -1), x) For a function like: unsigned f(unsigned s, int x) { return s + (x>0); } We now produce: cmp r1, #0 it gt addgt.w r0, r0, #1 Instead of: movs r2, #0 cmp r1, #0 it gt movgt r2, #1 add r0, r2 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162177 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-18Also pass logical ops to combineSelectAndUse.Jakob Stoklund Olesen
Add these transformations to the existing add/sub ones: (and (select cc, -1, c), x) -> (select cc, x, (and, x, c)) (or (select cc, 0, c), x) -> (select cc, x, (or, x, c)) (xor (select cc, 0, c), x) -> (select cc, x, (xor, x, c)) The selects can then be transformed to a single predicated instruction by peephole. This transformation will make it possible to eliminate the ISD::CAND, COR, and CXOR custom DAG nodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162176 91177308-0d34-0410-b5e6-96231b3b80d8
