* Include st_dev to make the result of getUniqueID actually unique.Rafael Espindola2013-07-291-12/+4
| | | | | | This will let us use getUniqueID instead of st_dev directly on clang. llvm-svn: 187378
* Revert "[PowerPC] Improve consistency in use of __ppc__, __powerpc__, etc."Rafael Espindola2013-07-261-2/+2
| | | | | | This reverts commit r187248. It broke many bots. llvm-svn: 187254
* [PowerPC] Improve consistency in use of __ppc__, __powerpc__, etc.Bill Schmidt2013-07-261-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Both GCC and LLVM will implicitly define __ppc__ and __powerpc__ for all PowerPC targets, whether 32- or 64-bit. They will both implicitly define __ppc64__ and __powerpc64__ for 64-bit PowerPC targets, and not for 32-bit targets. We cannot be sure that all other possible compilers used to compile Clang/LLVM define both __ppc__ and __powerpc__, for example, so it is best to check for both when relying on either inside the Clang/LLVM code base. This patch makes sure we always check for both variants. In addition, it fixes one unnecessary check in lib/Target/PowerPC/PPCJITInfo.cpp. (At least one of __ppc__ and __powerpc__ should always be defined when compiling for a PowerPC target, no matter which compiler is used, so testing for them is unnecessary.) There are some places in the compiler that check for other variants, like __POWERPC__ and _POWER, and I have left those in place. There is no need to add them elsewhere. This seems to be in Apple-specific code, and I won't take a chance on breaking it. There is no intended change in behavior; thus, no test cases are added. llvm-svn: 187248
* Add missing 'n'.Rafael Espindola2013-07-261-1/+1
| | | | | | Thanks to Han Finkel for noticing it. llvm-svn: 187241
* Remove dead or useless header checks from cmake and autoconfReid Kleckner2013-07-262-14/+4
| | | | | | | | | | On Windows, this improves clean cmake configuration time on my workstation from 1m58s to 1m32s, which is pretty significant. There's probably more that can be done here, but this is the low hanging fruit. Eric volunteered to regenerate ./configure for me. llvm-svn: 187209
* Extend the lifetime of the strings passed to posix_spawn_file_actions_addopen.Rafael Espindola2013-07-261-7/+21
| | | | | | Thanks to Hal Finkel for finding the bug and for the initial patch. llvm-svn: 187208
* Split openFileForWrite into windows and unix versions.Rafael Espindola2013-07-191-0/+25
| | | | | | It is similar to 186511, but for creating files for writing. llvm-svn: 186679
* Remove dead code.Rafael Espindola2013-07-181-59/+0
| | | | llvm-svn: 186561
* Split openFileForRead into Windows and Unix versions.Rafael Espindola2013-07-171-0/+9
| | | | | | | | | | | This has some advantages: * Lets us use native, utf16 windows functions. * Easy to produce good errors on windows about trying to use a directory when we want a file. * Simplifies the unix version a bit. llvm-svn: 186511
* Don't fallback to copy + delete in rename.Rafael Espindola2013-07-171-11/+2
| | | | | | | | | Rename's documentation says "Files are renamed as if by POSIX rename()". and it is used for atomically updating output files from a temporary. Having rename fallback to a non atomic copy has the potential to hide bugs, like using a temporary file in /tmp instead of a unique name next to the final destination. llvm-svn: 186483
* Add a version of sys::fs::status that uses fstat.Rafael Espindola2013-07-161-18/+30
| | | | llvm-svn: 186378
* Instead friending status, provide windows and posix constructors to file_status.Rafael Espindola2013-07-161-16/+12
| | | | | | | This opens the way of having static helpers in the .inc files that can construct a file_status. llvm-svn: 186376
* Revert part of 186302 to fix buildbots.Craig Topper2013-07-151-1/+2
| | | | llvm-svn: 186303
* Use llvm::array_lengthof to replace sizeof(array)/sizeof(array[0]).Craig Topper2013-07-151-6/+3
| | | | llvm-svn: 186301
* Fix a FIXME about the format and add a test.Rafael Espindola2013-07-111-12/+7
| | | | | | | While at it, use strftime on Unix too and use the thread safe versions of localtime. llvm-svn: 186090
* Use status to implement file_size.Rafael Espindola2013-07-101-14/+1
| | | | | | | | | | The status function is already using a syscall that returns the file size. Remember it and implement file_size as a simple wrapper. No functionally change, but clients that already use status now can avoid calling file_size. llvm-svn: 186016
* We now always create files with the correct permissions. Simplify the interface.Rafael Espindola2013-07-081-31/+1
| | | | llvm-svn: 185834
* Reapply r185601 with a fix for the cmake build.Eric Christopher2013-07-041-0/+10
| | | | llvm-svn: 185605
* Temporarily revert 185601 as it caused cmake build regressions.Eric Christopher2013-07-041-10/+0
| | | | llvm-svn: 185603
* Add support for futimens for platforms that don't support futimes.Eric Christopher2013-07-041-0/+10
| | | | | | Patch by pashev.igor. llvm-svn: 185601
* Suppress GCC "control reaches end of non-void function" warning.Patrik Hagglund2013-06-281-0/+1
| | | | llvm-svn: 185136
* Improvements to unique_file and createUniqueDirectory.Rafael Espindola2013-06-281-86/+70
| | | | | | | | | | | | | | | | | | | * Don't try to create parent directories in unique_file. It had two problem: * It violates the contract that it is atomic. If the directory creation success and the file creation fails, we would return an error but the file system was modified. * When creating a temporary file clang would have to first check if the parent directory existed or not to avoid creating one when it was not supposed to. * More efficient implementations of createUniqueDirectory and the unique_file that produces only the file name. Now all 3 just call into a static function passing what they want (name, file or directory). Clang also has to be updated, so tests might fail if a bot picks up this commit and not the corresponding clang one. llvm-svn: 185126
* Rename PathV2 to just Path now that it is the only one.Rafael Espindola2013-06-261-2/+2

| | | | | | With this we can remove the last use of PathV1 from llvm-ar.cpp. llvm-svn: 184464
* Add support for getting the last modification time from a file_status.Rafael Espindola2013-06-201-0/+7

* Only delete regular files and directories.Rafael Espindola2013-06-171-0/+16
| | | | | | | | This ports a missing feature from PathV1.h. I am not sure how to test this with the regular infrastructure, but an Apple bot should check this when r183985 is reapplied. llvm-svn: 184119
* Fix incorrectly finding 'executable' directories instead of files.Manuel Klimek2013-06-171-1/+8
| | | | | | | | | | | | | | | This broke for example the 'not' utility, if a directory called 'FileCheck' is executable and in the path before the actual 'FileCheck'. This patch steals the implementation of the "old" PathV1 canExecute implementation: - checks for R_OK (file readable): this is necessary for executing scripts; we should not regress here unless we have good reasons - checks for S_ISREG; if we want to get rid of this, we'd need to change all callers who already made the assumption when depending on Path V1. llvm-svn: 184074
* Add GetCurrentDirectory back.Rafael Espindola2013-06-141-0/+11
| | | | | | | | It looks like clang-tools-extra/unittests/cpp11-migrate/TransformTest.cpp depends on the behaviour of the old one on Windows. Maybe a difference between GetCurrentDirectoryA and GetCurrentDirectoryW? llvm-svn: 184009
