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

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115160 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-30This is the last major patch to implement support for the .loc directiveKevin Enderby
and output the dwarf line number tables. This contains the code to emit and encode the dwarf line tables from the previously gathered information in the MCLineSection objects. This contains all the details to encode the line and address deltas into the dwarf line table. To do this an MCDwarfLineAddrFragment has been added. Also this moves the interface code out of Mach-O streamer into MCDwarf so it should be useable by other object file formats. There is now one call to be made from an MCObjectStreamer EmitInstruction() method: MCLineEntry::Make(this, getCurrentSection()); to create a line entry after each instruction is assembled. And one call call to be made from an MCObjectStreamer Finish() method: MCDwarfFileTable::Emit(this, DwarfLineSection); when getContext().hasDwarfFiles() is true and is passed a object file specific MCSection where to emit the dwarf file and the line tables. This appears to now be correct for 32-bit targets, at least x86. But the relocation entries for 64-bit Darwin needs some further work which is next up to work on. So for now the 64-bit Mach-O target does not output the dwarf file and line tables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115157 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-30Changes EvaluateAsAbsolute() to return the "current value" of the expressionKevin Enderby
if we are given a Layout object, even in cases when the value is not fixed. This will be needed by the final patch for the dwarf .loc support to size a new MCDwarf fragment needed to build and emit dwarf line number tables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115155 91177308-0d34-0410-b5e6-96231b3b80d8
