* ParseIR: don't take ownership of the MemoryBufferAlp Toker2014-06-27
| | | | | | | | | | clang was needlessly duplicating whole memory buffer contents in an attempt to satisfy unclear ownership semantics. Let's just hide internal LLVM quirks and present a simple non-owning interface. The public C API preserves previous behaviour for stability. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211861 91177308-0d34-0410-b5e6-96231b3b80d8

* Introduce a string_ostream string builder faciltyAlp Toker2014-06-26
| | | | | | | | | | | | | | | | | | | | string_ostream is a safe and efficient string builder that combines opaque stack storage with a built-in ostream interface. small_string_ostream<bytes> additionally permits an explicit stack storage size other than the default 128 bytes to be provided. Beyond that, storage is transferred to the heap. This convenient class can be used in most places an std::string+raw_string_ostream pair or SmallString<>+raw_svector_ostream pair would previously have been used, in order to guarantee consistent access without byte truncation. The patch also converts much of LLVM to use the new facility. These changes include several probable bug fixes for truncated output, a programming error that's no longer possible with the new interface. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211749 91177308-0d34-0410-b5e6-96231b3b80d8

* Random Number Generator (llvm)JF Bastien2014-06-25
| | | | | | | | | | | | | | | | | | | | | | | | Provides an abstraction for a random number generator (RNG) that produces a stream of pseudo-random numbers. The current implementation uses C++11 facilities and is therefore not cryptographically secure. The RNG is salted with the text of the current command line invocation. In addition, a user may specify a seed (reproducible builds). In clang, the seed can be set via -frandom-seed=X In the back end, the seed can be set via -rng-seed=X This is the llvm part of the patch. clang part: D3391 URL: http://reviews.llvm.org/D3390 Author: yln I'm landing this for the second time, it broke Windows bots the first time around. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211705 91177308-0d34-0410-b5e6-96231b3b80d8

* Re-apply r211399, "Generate native unwind info on Win64" with a fix to ↵NAKAMURA Takumi2014-06-25
| | | | | | | | | | | | | | | | | | | | | | | ignore SEH pseudo ops in X86 JIT emitter. -- This patch enables LLVM to emit Win64-native unwind info rather than DWARF CFI. It handles all corner cases (I hope), including stack realignment. Because the unwind info is not flexible enough to describe stack frames with a gap of unknown size in the middle, such as the one caused by stack realignment, I modified register spilling code to place all spills into the fixed frame slots, so that they can be accessed relative to the frame pointer.

* R600: Fix inconsistency in rsq instructions.Matt Arsenault2014-06-24
| | | | | | | | | | | | | R600 was using a clamped version of rsq, but SI was not. Add a new rsq_clamped intrinsic and use them consistently. It's unclear to me from the documentation what behavior the R600 instructions have, so I assume they have the legacy behavior described by the SI documents. For R600, use RECIPSQRT_IEEE for both llvm.AMDGPU.rsq.legacy and llvm.AMDGPU.rsq. R600 also has RECIPSQRT_FF, which I'm not sure how it fits in here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211637 91177308-0d34-0410-b5e6-96231b3b80d8
* Add new debug kind LocTrackingOnly.Diego Novillo2014-06-24
| | | | | | | | | | | | | | | | | | | | | | | | Summary: This new debug emission kind supports emitting line location information in all instructions, but stops code generation from emitting debug info to the final output. This mode is useful when the backend wants to track source locations during code generation, but it does not want to produce debug info. This is currently used by optimization remarks (-pass-remarks, -pass-remarks-missed and -pass-remarks-analysis). To prevent debug info emission, DIBuilder never inserts the annotation 'llvm.dbg.cu' when LocTrackingOnly is enabled.
