Akira Hatanaka e96273e75d Preparation for adding simple Mips64 instructions. 
llvm-svn: 140443
 2011-09-24 01:34:44 +00:00
Akira Hatanaka f25c37e384 Make changes in instruction and pattern definitions so that tablegen does not 
complain it cannot infer types in patterns. Fix a mistake in definition of 
SDT_MipsExtractElementF64.

Akira Hatanaka fba4bd62b1 Add pattern used to match MipsLo, which is needed when the instruction selector 
tries to match a dead MipsLo node (explanation in the link below).

Akira Hatanaka 27292638bd Set mayLoad or mayStore flags for SC and LL in order to prevent LICM from 
moving them out of the loop. Previously, stores and loads to a stack frame
object were inserted to accomplish this. Remove the code that was needed to do
this. Patch by Sasa Stankovic.

Akira Hatanaka 9f6f6f6ecc Rather than having printMemOperand change the way memory operands are printed 
based on a modifier, split it into two functions.

before the offset. This change will enable simplification of function
MipsRegisterInfo::eliminateFrameIndex.

Akira Hatanaka d8373a4680 Add comments for wrapper node patterns in MipsInstrInfo.td. 
llvm-svn: 132717
 2011-06-07 18:00:14 +00:00
Bruno Cardoso Lopes 98fc4c8bbc This patch implements atomic intrinsics atomic.load.add (sub,and,or,xor, 
nand), atomic.swap and atomic.cmp.swap, all in i8, i16 and i32 versions.
The intrinsics are implemented by creating pseudo-instructions, which are
then expanded in the method MipsTargetLowering::EmitInstrWithCustomInserter.

Patch by Sasa Stankovic.
