* Fix the R600 build.Rafael Espindola2013-05-102-3/+2

* [ms-inline asm] Fix a crasher when we fail on a direct match.Chad Rosier2013-05-102-6/+9
| | | | | | | | | | | | | | | | | | The issue was that the MatchingInlineAsm and VariantID args to the MatchInstructionImpl function weren't being set properly. Specifically, when parsing intel syntax, the parser thought it was parsing inline assembly in the at&t dialect; that will never be the case. The crash was caused when the emitter tried to emit the instruction, but the operands weren't set. When parsing inline assembly we only set the opcode, not the operands, which is used to lookup the instruction descriptor. rdar://13854391 and PR15945 Also, this commit reverts r176036. Now that we're correctly parsing the intel syntax the pushad/popad don't match properly. I've reimplemented that fix using a MnemonicAlias. llvm-svn: 181620

* Better output for long help strings for command-line options.Alexander Kornienko2013-05-101-8/+16
| | | | | | | | | | | | | | | | | | | | | Summary: This patch allows using \n inside long help strings for command-line options, so that all lines are equally indented. This is not a perfect solution, as we don't (and probably don't want to) know about terminal width, but it allows to format long help strings somehow readable without manually padding them with spaces. A motivating example is -help output from clang-format (source code in tools/clang-format/ClangFormat.cpp, see cl options offset, length, style, and dump-config).

* Implement AsmParser for ARM unwind directives.Logan Chien2013-05-102-27/+284
| | | | | | | | | | | | | | | | | | | This commit implements the AsmParser for fnstart, fnend, cantunwind, personality, handlerdata, pad, setfp, save, and vsave directives. This commit fixes some minor issue in the ARMELFStreamer: * The switch back to corresponding section after the .fnend directive. * Emit the unwind opcode while processing .fnend directive if there is no .handlerdata directive. * Emit the unwind opcode to .ARM.extab while processing .handlerdata even if .personality directive does not exist. llvm-svn: 181603

* Generate a compact unwind encoding in the face of a stack alignment push.Bill Wendling2013-05-091-0/+6
| | | | | | | | | | | | | We generate a `push' of a random register (%rax) if the stack needs to be aligned by the size of that register. However, this could mess up compact unwind generation. In particular, we want to still generate compact unwind in the presence of this monstrosity. Check if the push of of the %rax/%eax register. If it is and it's marked with the `FrameSetup' flag, then we can generate a compact unwind encoding for the function only if the push is the last FrameSetup instruction. llvm-svn: 181540

* Don't replace an alias in llvm.used with its target.Rafael Espindola2013-05-091-2/+102

* [XCore] Fix handling of functions where only the LR is spilled.Richard Osborne2013-05-091-27/+30
| | | | | | | | | | | | | | Previously we only checked if the LR required saving if the frame size was non zero. However because the caller reserves 1 word for the callee to use that doesn't count towards our frame size it is possible for the LR to need saving and for the frame size to be 0. We didn't hit when the LR needed saving because of a function calls because the 1 word of stack we must allocate for our callee means the frame size is always non zero in this case. However we can hit this case if the LR is clobbered in inline asm. llvm-svn: 181520
* InstCombine: Don't just copy known bits from the first operand of an srem.Benjamin Kramer2013-05-091-1/+1

* [PowerPC] Fix regression in generating @ha/@l relocsUlrich Weigand2013-05-081-1/+10
| | | | | | | | | | | | | | | | The patch I committed as revision 167864 introduced a regression that causes LLVM to no longer generate appropriate relocs for @ha/@l symbol references (but fail an assertion instead). This is fixed here by re-enabling support for the VK_PPC_GAS_HA16/ VK_PPC_GAS_LO16 variant kinds (and their Darwin variants) in PPCELFObjectWriter.cpp. Tested by running projects/test-suite in -m32 mode with the integrated assembler forced on. A standalone test case will be committed shortly as well. llvm-svn: 181450

* Debug Info: Support DW_TAG_imported_declarationDavid Blaikie2013-05-081-1/+3
| | | | | | | | | | | | | | This provides basic functionality for imported declarations. For subprograms and types some amount of lazy construction is supported (so the definition of a function can proceed the using declaration), but it still doesn't handle declared-but-not-defined functions (since we don't generally emit function declarations). Variable support is really rudimentary at the moment - simply looking up the existing definition with no support for out of order (declaration, imported_module, then definition). llvm-svn: 181392
