2011-01-10Rename TargetFrameInfo into TargetFrameLowering. Also, put couple of FIXMEs ↵Anton Korobeynikov

2011-01-07Do not model all INLINEASM instructions as having unmodelled side effects.Evan Cheng
Instead encode llvm IR level property "HasSideEffects" in an operand (shared with IsAlignStack). Added MachineInstrs::hasUnmodeledSideEffects() to check the operand when the instruction is an INLINEASM. This allows memory instructions to be moved around INLINEASM instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123044 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-07Add ARM patterns to match EXTRACT_SUBVECTOR nodes.Bob Wilson
Also fix an off-by-one in SelectionDAGBuilder that was preventing shuffle vectors from being translated to EXTRACT_SUBVECTOR. Patch by Tim Northover. The test changes are needed to keep those spill-q tests from testing aligned spills and restores. If the only aligned stack objects are spill slots, we no longer realign the stack frame. Prior to this patch, an EXTRACT_SUBVECTOR was legalized by loading from the stack, which created an aligned frame index. Now, however, there is nothing except the spill slot in the stack frame, so I added an aligned alloca. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122995 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-30Massive rewrite of MMX: Dale Johannesen
The x86_mmx type is used for MMX intrinsics, parameters and return values where these use MMX registers, and is also supported in load, store, and bitcast. Only the above operations generate MMX instructions, and optimizations do not operate on or produce MMX intrinsics. MMX-sized vectors <2 x i32> etc. are lowered to XMM or split into smaller pieces. Optimizations may occur on these forms and the result casted back to x86_mmx, provided the result feeds into a previous existing x86_mmx operation. The point of all this is prevent optimizations from introducing MMX operations, which is unsafe due to the EMMS problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115243 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-30When isel is emitting instructions for an x86 target without CMOV, the CFG isJakob Stoklund Olesen
edited during emission. If the basic block ends in a switch that gets lowered to a jump table, any phis at the default edge were getting updated wrong. The jump table data structure keeps a pointer to the header blocks that wasn't getting updated after the MBB is split. This bug was exposed on 32-bit Linux when disabling critical edge splitting in codegen prepare. The fix is to uipdate stale MBB pointers whenever a block is split during emission. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115191 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-23SDISel should not optimize a unconditional branch following a conditional branchEvan Cheng
when the unconditional branch destination is the fallthrough block. The canonicalization makes it easier to allow optimizations on DAGs to invert conditional branches.
