* Move TargetRegistry and TargetSelect from Target to Support where they belong.Evan Cheng2011-08-241-1/+1
| | | | | | These are strictly utilities for registering targets and components. llvm-svn: 138450
* Remove unused Target argument from AsmParser construction methods.Jim Grosbach2011-08-161-1/+1
| | | | | | The argument is unused, and is a layering violation in any case. llvm-svn: 137735
* Rename TargetAsmParser to MCTargetAsmParser and TargetAsmLexer to ↵Evan Cheng2011-07-261-2/+3
| | | | | | MCTargetAsmLexer; rename createAsmLexer to createMCAsmLexer and createAsmParser to createMCAsmParser. llvm-svn: 136027

* Change createAsmParser to take a MCSubtargetInfo instead of triple,Evan Cheng2011-07-091-5/+10
| | | | | | | | | CPU, and feature string. Parsing some asm directives can change subtarget state (e.g. .code 16) and it must be reflected in other modules (e.g. MCCodeEmitter). That is, the MCSubtargetInfo instance must be shared. llvm-svn: 134795
* Eliminate asm parser's dependency on TargetMachine:Evan Cheng2011-07-081-1/+6
| | | | | | | | | | - Each target asm parser now creates its own MCSubtatgetInfo (if needed). - Changed AssemblerPredicate to take subtarget features which tablegen uses to generate asm matcher subtarget feature queries. e.g. "ModeThumb,FeatureThumb2" is translated to "(Bits & ModeThumb) != 0 && (Bits & FeatureThumb2) != 0". llvm-svn: 134678
* Do not model all INLINEASM instructions as having unmodelled side effects.Evan Cheng2011-01-071-1/+1
| | | | | | | | | | 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. llvm-svn: 123044

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SrcMgrDiagHandler, we can improve clang diagnostics for inline asm: instead of reporting them on a source line of the original line, we can report it on the correct line wherever the string literal came from. For something like this: void foo() { asm("push %rax\n" ".code32\n"); } we used to get this: (note that the line in t.c isn't helpful) t.c:4:7: error: warning: ignoring directive for now asm("push %rax\n" ^ <inline asm>:2:1: note: instantiated into assembly here .code32 ^ now we get: t.c:5:8: error: warning: ignoring directive for now ".code32\n" ^ <inline asm>:2:1: note: instantiated into assembly here .code32 ^ Note that we're pointing to line 5 properly now. llvm-svn: 119488
* now that AsmPrinter::EmitInlineAsm is factored right, we can eliminate theChris Lattner2010-11-171-9/+5
| | | | | | | | cookie argument to the SourceMgr diagnostic stuff. This cleanly separates LLVMContext's inlineasm handler from the sourcemgr error handling definition, increasing type safety and cleaning things up. llvm-svn: 119486

* Target: Give the TargetAsmParser access to the TargetMachine.Daniel Dunbar2010-07-191-1/+1
| | | | | | - Unfortunate, but necessary for now to handle subtarget instruction matching. Eventually we should factor out the lower level target machine information so we don't need to do this. llvm-svn: 108664
* MC: Move several clients to using AsmParser constructor function.Daniel Dunbar2010-07-181-6/+7

* Propagate the AlignStack bit in InlineAsm's to the Dale Johannesen2010-07-021-1/+1
| | | | | | | | | | | | | | | | | | | PrologEpilog code, and use it to determine whether the asm forces stack alignment or not. gcc consistently does not do this for GCC-style asms; Apple gcc inconsistently sometimes does it for asm blocks. There is no convenient place to put a bit in either the SDNode or the MachineInstr form, so I've added an extra operand to each; unlovely, but it does allow for expansion for more bits, should we need it. PR 5125. Some existing testcases are affected. The operand lists of the SDNode and MachineInstr forms are indexed with awesome mnemonics, like "2"; I may fix this someday, but not now. I'm not making it any worse. If anyone is inspired I think you can find all the right places from this patch. llvm-svn: 107506

* introduce a new recoverable error handling API to LLVMContextChris Lattner2010-04-071-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | and use it in one place in inline asm handling stuff. Before we'd generate this for an invalid modifier letter: $ clang asm.c -c -o t.o fatal error: error in backend: Invalid operand found in inline asm: 'abc incl ${0:Z}' INLINEASM <es:abc incl ${0:Z}>, 10, %EAX<def>, 2147483657, %EAX, 14, %EFLAGS<earlyclobber,def,dead>, <!-1> Now we generate this: $ clang asm.c -c -o t.o error: invalid operand in inline asm: 'incl ${0:Z}' asm.c:3:12: note: generated from here __asm__ ("incl %Z0" : "+r" (X)); ^ 1 error generated. This is much better but still admittedly not great ("why" is the operand invalid??), codegen should try harder with its diagnostics :) llvm-svn: 100723
