Add tests for the various combines. This should always be at least cycle neutral on all subtargets for f64, and faster on some. For f32 we should prefer selecting v_mad_f32 over v_fma_f32. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@227484 91177308-0d34-0410-b5e6-96231b3b80d8

2015-01-29DebugInfo: Teach Fast ISel to respect the debug location of comparisons in jumpsDavid Blaikie1-9/+9
The use of the DbgLoc in FastISel is probably something we should fix. It's prone to leaking the wrong location into instructions - we should have a clear chain of custody from the debug location of an IR Instruction to that of a MachineInstr to avoid such leakage. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@227481 91177308-0d34-0410-b5e6-96231b3b80d8
2015-01-29Disable compilation of llvm-pdbdump for versions of MSVC < 2013.Zachary Turner1-1/+4
Certain aspects of llvm-pdbdump require language support only present in MSVC 2013 and higher. Since this is strictly a utility, and since we hope to drop support for MSVC 2012 soon, don't build this unless MSVC 2013 or higher. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@227479 91177308-0d34-0410-b5e6-96231b3b80d8

2015-01-29Compute the ELF SectionKind from the flags.Rafael Espindola21-393/+198
Any code creating an MCSectionELF knows ELF and already provides the flags. SectionKind is an abstraction used by common code that uses a plain MCSection. Use the flags to compute the SectionKind. This removes a lot of guessing and boilerplate from the MCSectionELF construction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@227476 91177308-0d34-0410-b5e6-96231b3b80d8

2015-01-29[X86] Use single add/sub for large stack offsetsRobert Lougher2-13/+105
For large stack offsets the compiler generates multiple immediate mode sub/add instructions in the prologue/epilogue.

2015-01-29[PowerPC] Complete setting the baseline for ppc64leBill Schmidt2-2/+10
Patch by Nemanja Ivanovic. As was uncovered by the failing test case (when run on non-PPC platforms), the feature set when compiling with -march=ppc64le was not being picked up.

2015-01-29Don't create multiple mergeable sections with -fdata-sections.Rafael Espindola2-12/+13
ELF has support for sections that can be split into fixed size or null terminated entities. Since these sections can be split by the linker, it is not necessary to split them in codegen. This reduces the combined .o size in a llvm+clang build from 202,394,570 to 173,819,098 bytes. The time for linking clang with gold (on a VM, on a laptop) goes from 2.250089985 to 1.383001792 seconds. The flip side is the size of rodata in clang goes from 10,926,785 to 10,929,345 bytes. The increase seems to be because of http://sourceware.org/bugzilla/show_bug.cgi?id=17902. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@227431 91177308-0d34-0410-b5e6-96231b3b80d8

to get a powerpc64 host so that I can reproduce and test this, but it only impacts that platform so trying the only other realistic option. According to Ulrich, who debugged this initially, initial-exec is likely to be sufficient for our needs and not subject to this bug. Will watch the build bots to see. If this doesn't work, I'll be forced to cut a really ugly pthread-based approach into the primary user (our stack trace printing) as that user cannot use the ThreadLocal implementation due to lifetime issues. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@227414 91177308-0d34-0410-b5e6-96231b3b80d8

2015-01-29[LPM] Clean up the use of TLS in pretty stack trace and disable itChandler Carruth2-20/+37
entirely when threads are not enabled. This should allow anyone who needs to bootstrap or cope with a host loader without TLS support to limp along without threading support. There is still some bug in the PPC TLS stuff that is not worked around. I'm getting access to a machine to reproduce and debug this further. There is some chance that I'll have to add a terrible workaround for PPC. There is also some problem with iOS, but I have no ability to really evaluate what the issue is there. I'm leaving it to folks maintaining that platform to suggest a path forward -- personally I don't see any useful path forward that supports threading in LLVM but does so without support for *very basic* TLS. Note that we don't need more than some pointers, and we don't need constructors, destructors, or any of the other fanciness which remains widely unimplemented. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@227411 91177308-0d34-0410-b5e6-96231b3b80d8

2015-01-29Add a Windows EH preparation pass that zaps resumesReid Kleckner8-3/+199
If the personality is not a recognized MSVC personality function, this pass delegates to the dwarf EH preparation pass. This chaining supports people on *-windows-itanium or *-windows-gnu targets. Currently this recognizes some personalities used by MSVC and turns resume instructions into traps to avoid link errors. Even if cleanups are not used in the source program, LLVM requires the frontend to emit a code path that resumes unwinding after an exception. Clang does this, and we get unreachable resume instructions. PR20300 covers cleaning up these unreachable calls to resume.
