2013-02-11Revert "Rename LLVMContext diagnostic handler types and functions."Bob Wilson
This reverts my commit 171047. Now that I've removed my misguided attempt to support backend warnings, these diagnostics are only about inline assembly. It would take quite a bit more work to generalize them properly, so I'm just reverting this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174860 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-02Move all of the header files which are involved in modelling the LLVM IRChandler Carruth
into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project. I'll be committing updates to Clang, DragonEgg, and Polly momentarily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171366 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-25Rename LLVMContext diagnostic handler types and functions.Bob Wilson
These are now generally used for all diagnostics from the backend, not just for inline assembly, so this drops the "InlineAsm" from the names. No functional change. (I've left aliases for the old names but only for long enough to let me switch over clang to use the new ones.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171047 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-03Use the new script to sort the includes of every file under lib.Chandler Carruth
Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-21The inline asm operand modifier 'n' is suppose Jack Carter
to be generic across architectures. It has the following description in the gnu sources: Negate the immediate constant Several Architectures such as x86 have local implementations of operand modifier 'n' which go beyond the above description slightly. This won't affect them. Affected files: lib/CodeGen/AsmPrinter/AsmPrinterInlineAsm.cpp Added 'n' to the switch cases. test/CodeGen/Generic/asm-large-immediate.ll Generic compiled test (x86 for me) test/CodeGen/Mips/asm-large-immediate.ll Mips compiled version of the generic one Contributer: Jack Carter git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158939 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-21The inline asm operand modifier 'c' is suppose Jack Carter
to be generic across architectures. It has the following description in the gnu sources: Substitute immediate value without immediate syntax Several Architectures such as x86 have local implementations of operand modifier 'c' which go beyond the above description slightly. To make use of the generic modifiers without overriding local implementation one can make a call to the base class method for AsmPrinter::PrintAsmOperand() in the locally derived method's "default" case in the switch statement. That way if it is already defined locally the generic version will never get called. This change is needed when test/CodeGen/generic/asm-large-immediate.ll failed on a native Mips board. The test was assuming a generic implementation was in place. Affected files: lib/Target/Mips/MipsAsmPrinter.cpp: Changed the default case to call the base method. lib/CodeGen/AsmPrinter/AsmPrinterInlineAsm.cpp Added 'c' to the switch cases. test/CodeGen/Mips/asm-large-immediate.ll Mips compiled version of the generic one Contributer: Jack Carter git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158925 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-09Change createAsmParser to take a MCSubtargetInfo instead of triple,Evan Cheng
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134795 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-08Eliminate asm parser's dependency on TargetMachine:Evan Cheng
- 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". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134678 91177308-0d34-0410-b5e6-96231b3b80d8
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
2010-11-17With the newly simplified SourceMgr interfaces and the generalizedChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119488 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-17now that AsmPrinter::EmitInlineAsm is factored right, we can eliminate theChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119486 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-19Target: Give the TargetAsmParser access to the TargetMachine.Daniel Dunbar

2010-07-02Propagate the AlignStack bit in InlineAsm's to the Dale Johannesen
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107506 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-07introduce a new recoverable error handling API to LLVMContextChris Lattner
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.
