* StringRef-ify some Option APIsDavid Blaikie2015-11-171-26/+25
| | | | | | | | Patch by Eugene Kosov! Differential Revision: http://reviews.llvm.org/D14711 llvm-svn: 253360
* [Support] Tweak path::system_temp_directory() on Windows.Pawel Bylica2015-11-171-16/+15
| | | | | | | | | | | | | | | | | Summary: This patch changes the behavior of path::system_temp_directory() on Windows to be closer to GetTempPath Windows API call. Enforces path separator to be the native one, makes path absolute, etc. GetTempPath is not used directly because of limitations/implementation bugs on Windows 7. Windows specific unit tests are added. Most of them runs in separated process with modified environment variables. This change fixes FileSystemTest.CreateDir unittest that had been failing when run from Unix-like shell on Windows (Unix-like path separator (/) used in env variables).

* [JIT/Memory] Fix up semantic of setExecutable().Davide Italiano2015-11-171-4/+1

* Handle ARMv6KZ namingArtyom Skrobov2015-11-162-4/+3
| | | | | | | | | | | | | | | | | | | | | | | Summary: * ARMv6KZ is the "canonical" name, given in the ARMARM * ARMv6Z is an "official abbreviation" for it, mentioned in the ARMARM * ARMv6ZK is a popular misspelling, which we should support as an alias. The patch corrects the handling of the names. Functional changes: * ARMv6Z no longer treated as an architecture in its own right * ARMv6ZK renamed to ARMv6KZ, accepting ARMv6ZK as an alias * arm1176jz-s and arm1176jzf-s recognized as ARMv6ZK, instead of ARMv6K * default ARMv6K CPU changed to arm1176j-s Reviewers: rengolin, logan, compnerd Subscribers: aemerson, llvm-commits, rengolin Differential Revision: http://reviews.llvm.org/D14568 llvm-svn: 253206

* [ARM] Allow TargetParser to accurately target architecturesBradley Smith2015-11-161-5/+14
| | | | | | | | | | | | Instead of defaulting to an empty string, we want to default to the CPU 'generic' in the case of no valid default CPU being found, (as long as the architecture is actually valid). In order to do this we add a default FPU for each architecture, as well as falling back to architecture defaults for extensions and FPU in the case of a generic CPU is specified. llvm-svn: 253198

* [Support] Use GetTempDir to get the temporary dir path on Windows.Pawel Bylica2015-11-061-37/+10
| | | | | | | | | | | | | | | Summary: In general GetTempDir follows the same logic as the replaced code: checks env variables TMP, TEMP, USERPROFILE in order. However, it also perform other checks like making separators native (\), making the path absolute, etc. This change fixes FileSystemTest.CreateDir unittest that had been failing when run from Unix-like shell on Windows (Unix-like path separator (/) used in env variables).

* [Windows] Symbolize with llvm-symbolizer instead of dbghelp in a self-hostReid Kleckner2015-11-053-97/+227
| | | | | | | | | | | | | | | | Summary: llvm-symbolizer understands both PDBs and DWARF, so it is more likely to succeed at symbolization. If llvm-symbolizer is unavailable, we will fall back to dbghelp. This also makes our crash traces more similar between Windows and Linux.

| | | | | | | | | | | | | | | | | | | | Summary: The new function sys::path::user_cache_directory tries to discover a directory suitable for cache storage for current system user. On Windows and Darwin it returns a path to system-specific user cache directory. On Linux it follows XDG Base Directory Specification, what is: - use non-empty $XDG_CACHE_HOME env var, - use $HOME/.cache.

* Fix rename() sometimes failing if another process uses openFileForRead()Greg Bedwell2015-10-121-10/+28
| | | | | | | | | | | | | | | | | | | On Windows, fs::rename() could fail is another process was reading the file at the same time using fs::openFileForRead(). In most cases the user wouldn't notice as fs::rename() will continue to retry for 2000ms. Typically this is enough for the read to complete and a retry to succeed, but if the disk is being it too hard then the response time might be longer than the retry time and the rename would fail with a permission error. Add FILE_SHARE_DELETE to the sharing flags for CreateFileW() in fs::openFileForRead() and try ReplaceFileW() prior to MoveFileExW() in fs::rename(). Based on an initial patch by Edd Dawson!

* Support: Stop relying on iterator auto-conversion, NFCDuncan P. N. Exon Smith2015-10-081-6/+6
| | | | | | | | | | | | | | Stop relying on ilist implicit conversions from `value_type&` to `iterator` in YAMLParser.cpp. I eventually want to outlaw this entirely. It encourages `getNextNode()` and `getPrevNode()` in iterator logic, which is extremely fragile (and relies on them never returning `nullptr`). FTR, there's nothing nefarious going on in this case, it was just easy to clean up since the callers really wanted iterators to begin with. llvm-svn: 249767

* [BranchProbability] Manually round the floating point output.Benjamin Kramer2015-09-261-28/+7
| | | | | | | | | | | llvm::format compiles down to snprintf which has no defined rounding for floating point arguments, and MSVC has implemented it differently from what the BSD libcs and glibc do. Try to emulate the glibc rounding behavior to avoid changing tests. While there simplify code a bit and move trivial methods inline. llvm-svn: 248665
* Use fixed-point representation for BranchProbability.Cong Hou2015-09-251-5/+51
| | | | | | | | | | | | | | | | | | | | BranchProbability now is represented by its numerator and denominator in uint32_t type. This patch changes this representation into a fixed point that is represented by the numerator in uint32_t type and a constant denominator 1<<31. This is quite similar to the representation of BlockMass in BlockFrequencyInfoImpl.h. There are several pros and cons of this change: Pros: 1. It uses only a half space of the current one. 2. Some operations are much faster like plus, subtraction, comparison, and scaling by an integer. Cons: 1. Constructing a probability using arbitrary numerator and denominator needs additional calculations. 2. It is a little less precise than before as we use a fixed denominator. For example, 1 - 1/3 may not be exactly identical to 1 / 3 (this will lead to many BranchProbability unit test failures). This should not matter when we only use it for branch probability. If we use it like a rational value for some precise calculations we may need another construct like ValueRatio. One important reason for this change is that we propose to store branch probabilities instead of edge weights in MachineBasicBlock. We also want clients to use probability instead of weight when adding successors to a MBB. The current BranchProbability has more space which may be a concern.

* [ARM] Handle +t2dsp feature as an ArchExtKind in ARMTargetParser.defArtyom Skrobov2015-09-241-0/+5
| | | | | | | | | | | | | | | | | | Currently, the availability of DSP instructions (ACLE 6.4.7) is handled in a hand-rolled tricky condition block in tools/clang/lib/Basic/Targets.cpp, with a FIXME: attached. This patch changes the handling of +t2dsp to be in line with other architecture extensions. Following a revert of r248152 and new review comments, this patch also includes renaming FeatureDSPThumb2 -> FeatureDSP, hasThumb2DSP() -> hasDSP(), etc. The spelling of "t2dsp" is preserved, pending a further investigation of its possible external usage.
