* It's not legal to fold a load from a narrower stack slot into a wider ↵Evan Cheng2009-09-11

One exception is when the instruction that folds the load is a move, then we can simply turn it into a 32-bit load from the stack slot. rdar://7170444 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81494 91177308-0d34-0410-b5e6-96231b3b80d8
* Added the ParseInstruction() hook for target specific assembler directives soKevin Enderby2009-09-10
| | | | | | | | | that things like .word can be parsed as target specific. Moved parsing .word out of AsmParser.cpp into X86AsmParser.cpp as it is 2 bytes on X86 and 4 bytes for other targets that support the .word directive. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81461 91177308-0d34-0410-b5e6-96231b3b80d8

* remove DebugLoc from MCInst and eliminate "Comment printing" fromChris Lattner2009-09-09
| | | | | | | | | | | | | | | the MCInst path of the asmprinter. Instead, pull comment printing out of the autogenerated asmprinter into each target that uses the autogenerated asmprinter. This causes code duplication into each target, but in a way that will be easier to clean up later when more asmprinter stuff is commonized into the base AsmPrinter class. This also fixes an xcore strangeness where it inserted two tabs before every instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81396 91177308-0d34-0410-b5e6-96231b3b80d8

* hoist the call to processDebugLoc out of the generatedChris Lattner2009-09-09
| | | | | | | | | | | | | | asm printer into the "printInstruction" routine. This fixes a problem where the experimental asmprinter would drop debug labels in some cases, and fixes issues on ppc/xcore where pseudo instructions like "mr" didn't get debug locs properly. It is annoying that this moves the call from one place into each target, but a future set of more invasive refactorings will fix that problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81377 91177308-0d34-0410-b5e6-96231b3b80d8
