* Handle ARMv6-J as an alias, instead of fake architectureArtyom Skrobov2015-11-202-2/+1
| | | | | | | | | | | | | | | | | | | | | | Summary: This follows D14577 to treat ARMv6-J as an alias for ARMv6, instead of an architecture in its own right. The functional change is that the default CPU when targeting ARMv6-J changes from arm1136j-s to arm1136jf-s, which is currently used as the default CPU for ARMv6; both are, in fact, ARMv6-J CPUs. The J-bit (Jazelle support) is irrelevant to LLVM, and it doesn't affect code generation, attributes, optimizations, or anything else, apart from selecting the default CPU.

* [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).

* 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
* Cull non-standard variants of ARM architectures (NFC)Artyom Skrobov2015-11-122-20/+5

* [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
