2012-08-24Missed tLEApcrelJT.Jakob Stoklund Olesen
ARMConstantIslandPass expects this instruction to stay in the same basic block as the jump table branch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162615 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-24Explicitly mark LEApcrel pseudos with hasSideEffects.Jakob Stoklund Olesen
It's not clear that they should be marked as such, but tbb formation fails if t2LEApcrelJT is hoisted of of a loop. This doesn't change the flags on these instructions, UnmodeledSideEffects was already inferred from the missing pattern. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162603 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-24Fix call instruction operands in ARMFastISel.Jakob Stoklund Olesen
The ARM BL and BLX instructions don't have predicate operands, but the thumb variants tBL and tBLX do. The argument registers should be added as implicit uses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162593 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-24Mark X86::RET and RETI instructions as variadic.Jakob Stoklund Olesen
There is special magic happening when returning floating point values on the x87 stack. The RET instructions get extra f80 operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162592 91177308-0d34-0410-b5e6-96231b3b80d8

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.

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 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

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] 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
