2013-02-16[ms-inline asm] Do not omit the frame pointer if we have ms-inline assembly.Chad Rosier
If the frame pointer is omitted, and any stack changes occur in the inline assembly, e.g.: "pusha", then any C local variable or C argument references will be incorrect.

When we're recalculating the feature set of the subtarget, we need to have the ivars in their initial state. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175320 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-15Use the 'target-features' and 'target-cpu' attributes to reset the subtarget ↵Bill Wendling
features. If two functions require different features (e.g., `-mno-sse' vs. `-msse') then we want to honor that, especially during LTO. We can do that by resetting the subtarget's features depending upon the 'target-feature' attribute. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175314 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-13X86: Disable generation of rep;movsl when %esi is used as a base pointer.Benjamin Kramer
This happens when there is both stack realignment and a dynamic alloca in the function. If we overwrite %esi (rep;movsl uses fixed registers) we'll lose the base pointer and the next register spill will write into oblivion. Fixes PR15249 and unbreaks firefox on i386/freebsd. Mozilla uses dynamic allocas and freebsd a 4 byte stack alignment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175057 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-06This is a follow-up on r174446, now taking Atom processors intoEli Bendersky
account. Atoms use LEA for updating SP in prologs/epilogs, and the exact LEA opcode depends on the data model. Also reapplying the test case which was added and then reverted (because of Atom failures), this time specifying explicitly the CPU in addition to the triple. The test case now checks all variations (data mode, cpu Atom vs. Core). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174542 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-04More MSan/ASan annotations.Evgeniy Stepanov
This change lets us bootstrap LLVM/Clang under ASan and MSan. It contains fixes for 2 issues: - X86JIT reads return address from stack, which MSan does not know is initialized. - bugpoint tests run binaries with RLIMIT_AS. This does not work with certain Sanitizers. We are no longer including config.h in Compiler.h with this change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174306 91177308-0d34-0410-b5e6-96231b3b80d8

conditions are met: 1. They share the same operand and are in the same BB. 2. Both outputs are used. 3. The target has a native instruction that maps to ISD::FSINCOS node or the target provides a sincos library call. Implemented the generic optimization in sdisel and enabled it for Mac OSX. Also added an additional optimization for x86_64 Mac OSX by using an alternative entry point __sincos_stret which returns the two results in xmm0 / xmm1. rdar://13087969 PR13204 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173755 91177308-0d34-0410-b5e6-96231b3b80d8
