* Fix CodeGen/PowerPC/stack-protector.ll on OpenBSDHal Finkel2013-06-281-2/+3
| | | | | | | | | | | | | | On OpenBSD, the stack-smash protection transform uses "__guard_local" and "__stack_smash_handler" instead of "__stack_chk_guard" and "__stack_chk_fail". However, CodeGen/PowerPC/stack-protector.ll doesn't specify a target OS, so on OpenBSD it fails. Add -mtriple=ppc32-unknown-linux to make the test host-OS agnostic. While there, convert to FileCheck. Patch by Matthew Dempsky. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185206 91177308-0d34-0410-b5e6-96231b3b80d8
* DebugInfo: PR14728: TLS supportDavid Blaikie2013-06-286-3/+69
| | | | | | | | | | | | | | Based on GCC's output for TLS variables (OP_constNu, x@dtpoff, OP_lo_user), this implements debug info support for TLS in ELF. Verified that this output is correct/sufficient on Linux (using gold - if you're using binutils-ld, you'll need something with the fix for http://sourceware.org/bugzilla/show_bug.cgi?id=15685 in it). Support on non-ELF is sort of "arbitrary" at the moment - if Apple folks want to discuss (or just go ahead & implement) how this should work in MachO, etc, I'm open. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185203 91177308-0d34-0410-b5e6-96231b3b80d8
* DebugInfo: Pass MCSymbolRefExprs for labels instead of MCSymbolsDavid Blaikie2013-06-285-13/+26
| | | | | | | This is a precursor to adding debug info support for TLS which requires non-default relocations applied to TLS symbols. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185202 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix a PPC rlwimi instruction-selection bugHal Finkel2013-06-282-2/+46
| | | | | | | | | Under certain (evidently rare) circumstances, this code used to convert OR(a, AND(x, y)) into OR(a, x). This was incorrect. While there, I've added a comment to the code immediately above. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185201 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | I used the class to safely reset the state of the builder's debug location. I think I have caught all places where we need to set the debug location to a new one. Therefore, we can replace the class by a function that just sets the debug location. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185165 91177308-0d34-0410-b5e6-96231b3b80d8

* ARM: ensure fixed-point conversions have sane typesTim Northover2013-06-283-5/+118
| | | | | | | | | | | We were generating intrinsics for NEON fixed-point conversions that didn't exist (e.g. float -> i16). There are two cases to consider: + iN is smaller than float. In this case we can do the conversion but need an extend or truncate as well. + iN is larger than float. In this case using the NEON conversion would be incorrect so we don't perform any combining. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185158 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | * Don't try to create parent directories in unique_file. It had two problem: * It violates the contract that it is atomic. If the directory creation success and the file creation fails, we would return an error but the file system was modified. * When creating a temporary file clang would have to first check if the parent directory existed or not to avoid creating one when it was not supposed to. * More efficient implementations of createUniqueDirectory and the unique_file that produces only the file name.
