Daniel Dunbar 9b92e2be30 sys::Process: Add a SetWorkingDirectory method. 
llvm-svn: 140433
 2011-09-23 23:23:36 +00:00
Bob Wilson 49621cb209 Remove the hack to check UNAME_RELEASE when identifying the Darwin version. 
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.

Bill Wendling bdaa57fe6d Include limits.h to make sure PATH_MAX is known on Solaris 10.

Bob Wilson de9ec45e5a Recognize the UNAME_RELEASE environment variable to match Darwin's uname. 
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.

Nick Lewycky 9ee5f77141 Don't look at $PWD in GetCurrentDirectory. 
llvm-svn: 136477
 2011-07-29 18:26:59 +00:00
Nick Lewycky 38b9b568b9 Teach Path::GetCurrentDirectory to use $PWD, to support users who like to do 
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.

Argyrios Kyrtzidis 348937de07 Add an optional 'bool makeAbsolute' in llvm::sys::fs::unique_file function. 
If true and 'model' parameter is not an absolute path, a temp directory will be prepended.
Make it true by default to match current behaviour.

Chad Rosier 30c3463309 By default mkstemp() creates a temporary file with mode 0600, but the mode 
used for open is 0666.  Therefore, add the necessary permission bits for
consistency.

info in the error message. Per Dan's request.

Rafael Espindola 0693182265 Don't include information about the build into the information returned by 
getHostTriple. This fixes a 32 bit clang running on a 64 bit ubuntu.

Andrew Trick 55aeb55aa3 Bugpoint support for miscompilations that result in a crash. 
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.

Benjamin Kramer dce83c522c Avoid initializing posix_spawn_file_actions_t if not used. 
- glibc falls back to fork+exec if a file actions object is present.
- On BSDs this saves a malloc.

Douglas Gregor 56b2ffdaba Rip out realpath() support. It's expensive, and often a bad idea, and 
I have another way to achieve the same goal.

Douglas Gregor 529329e859 Add llvm::sys::path::canonical(), which provides the canonicalized 
name of a path, after resolving symbolic links and eliminating excess
path elements such as "foo/../" and "./".

This routine still needs a Windows implementation, but I don't have a
Windows machine available. Help? Please?
