* Change default error_code ctor to a 'named ctor' so it's more self-documenting.David Blaikie2012-02-091-17/+17
| | | | | | | | | | | Unify default construction of error_code uses on this idiom so that users don't feel compelled to make static globals for naming convenience. (unfortunately I couldn't make the original ctor private as some APIs don't return their result, instead using an out parameter (that makes sense to default construct) - which is a bit of a pity. I did, however, find/fix some cases of unnecessary default construction of error_code before I hit the unfixable cases) llvm-svn: 150197
* Remove SetWorkingDirectory from the Process interface. Nothing in LLVMChandler Carruth2012-01-151-4/+0
| | | | | | | | | | | | or Clang is using this, and it would be hard to use it correctly given the thread hostility of the function. Also, it never checked the return which is rather dangerous with chdir. If someone was in fact using this, please let me know, as well as what the usecase actually is so that I can add it back and make it more correct and secure to use. (That said, it's never going to be "safe" per-se, but we could at least document the risks...) llvm-svn: 148211

* use getHostTriple instead of getDefaultTargetTriple in getClosestTargetForJITSebastian Pop2012-01-041-6/+12
| | | | | | | | | | Get back getHostTriple. For JIT compilation, use the host triple instead of the default target: this fixes some JIT testcases that used to fail when the compiler has been configured as a cross compiler. llvm-svn: 147542

* Remove the hack to check UNAME_RELEASE when identifying the Darwin version.Bob Wilson2011-09-201-9/+0
| | | | | | | | | This was only needed to locate llvm-gcc's installation directory when clang falls back to run llvm-gcc for i386 kexts. As of clang svn r140187, we're now just searching paths with several different Darwin versions on either side of the current version, so this is no longer needed. llvm-svn: 140188

* Recognize the UNAME_RELEASE environment variable to match Darwin's uname.Bob Wilson2011-08-091-0/+6
| | | | | | | | When this variable is set, "uname -r" will return its value instead of the real OS version. Make this affect LLVM's triple for consistency. <rdar://problem/9919167> llvm-svn: 137111

* Teach Path::GetCurrentDirectory to use $PWD, to support users who like to doNick Lewycky2011-07-291-2/+5
| | | | | | | | | | | | screwy things by setting PWD != getcwd(). For example, some developers I know will use this to control the value in gcc's DW_AT_comp_dir value in debug output. With this patch, that trick will now work on clang too. The only other effect of this change is that the static analysis will now respect $PWD when reporting the directory of the files in its HTML output. I think that's fine. llvm-svn: 136459
* Add an optional 'bool makeAbsolute' in llvm::sys::fs::unique_file function.Argyrios Kyrtzidis2011-07-281-8/+11

* Bugpoint support for miscompilations that result in a crash.Andrew Trick2011-05-111-2/+5
| | | | | | | | | This change allows bugpoint to pinpoint the "opt" pass and bitcode segment responsible for a crash caused by miscompilation. At least it works well for me now, without having to create any custom execution wrappers. llvm-svn: 131186
