* Testing for _XCR_XFEATURE_ENABLED_MASK instead of a specific MSVC version ↵Aaron Ballman2013-04-231-1/+1
| | | | | | because some MSVC 2010 SP1 installations do not have the _xgetbv intrinsic. Patch thanks to Serge Pavlov! llvm-svn: 180125

* [Support] Fix argv string escape bug on WindowsReid Kleckner2013-04-221-4/+42
| | | | | | | | | | | | | | | | Summary: This is http://llvm.org/PR15802. Backslashes preceding double quotes in arguments must be escaped. The interesting bit is that all other backslashes should *not* be escaped, because the un-escaping logic is only triggered by the presence of a double quote character.

* Make the host endianness check an integer constant expression.Rafael Espindola2013-04-152-3/+3
| | | | | | | | | | | | | | | I will remove the isBigEndianHost function once I update clang. The ifdef logic is designed to * not use configure/cmake to avoid breaking -arch i686 -arch ppc. * default to little endian * be as small as possible It looks like sys/endian.h is the preferred header on most modern BSD systems, but it is better to change this in a followup patch as machine/endian.h is available on FreeBSD, OpenBSD, NetBSD and OS X. llvm-svn: 179527
* Add a function to check if an argument list is too long.Rafael Espindola2013-04-112-0/+40
| | | | | | | | | This will be used in clang to decide if it should create an @file or not. It will be tested on the clang side. Patch by Nathan Froyd. llvm-svn: 179285
* <rdar://problem/13551789> Fix a race in the LockFileManager.Douglas Gregor2013-04-051-5/+32
| | | | | | | | It's possible for the lock file to disappear and the owning process to return before we're able to see the generated file. Spin for a little while to see if it shows up before failing. llvm-svn: 178909
* <rdar://problem/13551789> Fix yet another race in unique_file.Douglas Gregor2013-04-051-3/+1
| | | | | | | | | If the directory that will contain the unique file doesn't exist when we tried to create the file, but another process creates it before we get a chance to try creating it, we would bail out rather than try to create the unique file. llvm-svn: 178908

* [Support] Disable assertion dialogs from the MSVC debug CRTReid Kleckner2013-04-051-0/+22
| | | | | | | | | | | | | | | | Summary: Sets a report hook that emulates pressing "retry" in the "abort, retry, ignore" dialog box that _CrtDbgReport normally raises. There are many other ways to disable assertion reports, but this was the only way I could find that still calls our exception handler.

* Second pass at addressing PR15351 by explicitly checking for AVX supportAaron Ballman2013-04-031-2/+25
| | | | | | when getting the host processor information. It emits a .byte sequence on GNUC compilers to work around lack of xgetbv support with older assemblers, and resolves a comment typo found in the previous patch. llvm-svn: 178636
* Rolling back the AVX support patch due to breaking a gcc 4.6 build bot that ↵Aaron Ballman2013-04-031-23/+2

* Add a boolean parameter to the llvm::report_fatal_error() function to indicatedChad Rosier2013-03-271-8/+8

* Add a boolean parameter to the ExecuteAndWait static function to indicatedChad Rosier2013-03-261-4/+7
| | | | | | | | | | if execution failed. ExecuteAndWait returns -1 upon an execution failure, but checking the return value isn't sufficient because the wait command may return -1 as well. This new parameter is to be used by the clang driver in a subsequent commit. Part of rdar://13362359 llvm-svn: 178087

* Add a new watchdog timer interface. The interface does not permit handling ↵Nick Lewycky2013-03-265-1/+86
| | | | | | | | | timeouts, so it's only really useful if you're going to crash anyways. Use it in the pretty stack trace printer to kill the compiler if we hang while printing the stack trace. llvm-svn: 177962
* Revert r177543: Add timing of the IR parsing code with a newChandler Carruth2013-03-222-22/+0
| | | | | | | | | | | | | | | -time-ir-parsing flag This breaks the layering of the Support library. We can't add an implementation side to IRReader because it refers directly to entities only accessible as part of the IR, AsmParser, and BitcodeReader libraries. It can only be used in a context where all of those libraries will be available. We'll need to find some other way to get this functionality, and hopefully solve the long-standing layering problem of IRReader.h... llvm-svn: 177695
* <rdar://problem/13477190> On Darwin, use DARWIN_USER_TEMP_DIR or ↵Douglas Gregor2013-03-211-0/+24
| | | | | | | | | | DARWIN_USER_CACHE_DIR for the system temporary directory. The DARWIN_USER_TEMP_DIR and DARWIN_USER_CACHE_DIR configuration settings are more idiomatic for Darwin than the TMPDIR environment variable. llvm-svn: 177669
* Use pre-inc, pre-dec when possible.Jakub Staszak2013-03-201-4/+4
| | | | | | They are generally faster (at least not slower) than post-inc, post-dec. llvm-svn: 177608

* [Support] Fix lifetime of file descriptors when using MemoryBuffer.Michael J. Spencer2013-03-144-24/+37
| | | | | | | Clients of MemoryBuffer::getOpenFile expect it not to take ownership of the file descriptor passed in. So don't. llvm-svn: 176995
* Don't crash if write_impl() leaves less buffer space available than expected.Matt Beaumont-Gay2013-03-121-1/+6

* Disable statistics on Release builds and move tests that depend on -stats.Jan Wen Voung2013-03-081-1/+17
| | | | | | | | | | | | | | | | | Summary: Statistics are still available in Release+Asserts (any +Asserts builds), and stats can also be turned on with LLVM_ENABLE_STATS. Move some of the FastISel stats that were moved under DEBUG() back out of DEBUG(), since stats are disabled across the board now. Many tests depend on grepping "-stats" output. Move those into a orig_dir/Stats/. so that they can be marked as unsupported when building without statistics. Differential Revision: http://llvm-reviews.chandlerc.com/D486 llvm-svn: 176733
* In llvm::MemoryBuffer::getFile() remove an unnecessary stat call check.Argyrios Kyrtzidis2013-03-011-0/+3
| | | | | | | | | | The sys::fs::is_directory() check is unnecessary because, if the filename is a directory, the function will fail anyway with the same error code returned. Remove the check to avoid an unnecessary stat call. Someone needs to review on windows and see if the check is necessary there or not. llvm-svn: 176386
* [PathV2] In llvm::sys::fs::unique_file, make sure it doesn't fall into an ↵Argyrios Kyrtzidis2013-02-281-1/+7
| | | | | | | | | | | infinite loop by constantly trying to create the parent path. This can happen if the path is a relative filename and the current directory was removed. Thanks to Daniel D. for the hint in fixing it. llvm-svn: 176226
* Add support for autodetection of ADM bdver2.Roman Divacky2013-02-261-1/+4
| | | | llvm-svn: 176130
* Previously, parsing capability of the .debug_frame section was addedEli Bendersky2013-02-211-0/+1
| | | | | | | | | | | | | | | | to lib/DebugInfo, with dumping in llvm-dwarfdump. This patch adds initial ability to parse and dump CFA instructions contained in entries. To keep it manageable, the patch omits some more advanced capabilities (accounted in TODOs): * Parsing of instructions with BLOCK arguments (expression lists) * Dumping of actual instruction arguments (currently only names are dumped). This is quite tricky since the dumper has to effectively "interpret" the instructions. llvm-svn: 175820
* Provide a "None" value for convenience when using Optional<T>()David Blaikie2013-02-211-2/+2
| | | | | | | This implementation of NoneType/None does have some holes but I haven't found one that doesn't - open to improvement. llvm-svn: 175696
