* Revert "Get rid of GetProcessId in Win32/Program.inc.", this breaksDaniel Dunbar2009-09-222-22/+43
| | | | | | ExecuteAndWait. llvm-svn: 82522
* Get rid of GetProcessId in Win32/Program.inc.Mikhail Glushenkov2009-09-152-43/+22
| | | | | | | GetProcessId was introduced only in XP. As a bonus, this change makes Program objects copyable, since Program is now basically a PID. llvm-svn: 81826
* Experimental fix for PR4960.Daniel Dunbar2009-09-121-5/+14
| | | | | | - Could we just always implement this as __clear_cache for __GNUC__? llvm-svn: 81655
* Fix llvm-extract's "writing bitcode to a terminal" warning, which wasn'tDan Gohman2009-09-112-16/+14
| | | | | | | | | | | | | | | working. To support this, add an is_displayed() function to raw_ostream, and generalize Process::StandardOutIsDisplayed and friends in order to support it. Also, call RemoveFileOnSignal before creating a file instead of after, so that the file isn't left behind if the program is interrupted between when the file is created and RemoveFileOnSignal is called. While here, add a -S to llvm-extract and port it to IRReader so that it supports assembly input. llvm-svn: 81568
* Add a shortcut for OS X to Path::GetMainExecutable. This gives a nice speedup onBenjamin Kramer2009-09-091-1/+15

| | | | | | Thanks to Duncan Sands for spotting this. llvm-svn: 81328

* Remove some not-really-used variables, as warnedDuncan Sands2009-09-061-3/+0

* Tweak code into an equivalent form for which iccDuncan Sands2009-09-063-17/+13

| | | | llvm-svn: 79873
* Prune #includes from llvm/Linker.h and llvm/System/Path.h,Chris Lattner2009-08-237-26/+16
| | | | | | | | | | | | | | | | | | forcing them down into various .cpp files. This change also: 1. Renames TimeValue::toString() and Path::toString() to ::str() for similarity with the STL. 2. Removes all stream insertion support for sys::Path, forcing clients to call .str(). 3. Removes a use of Config/alloca.h from bugpoint, using smallvector instead. 4. Weans llvm-db off <iostream> sys::Path really needs to be gutted, but I don't have the desire to do it at this point. llvm-svn: 79869
* Get rid of a helgrind warning. If this is _actually_ a performance problem,Owen Anderson2009-08-191-3/+3
| | | | | | we can find a way to cache the answer that isn't racy. llvm-svn: 79472
* Add locking around signal handler registration.Owen Anderson2009-08-171-0/+14
| | | | llvm-svn: 79254

| | | | llvm-svn: 78215
* Remove needless uses of std::flush in the parent process after aDan Gohman2009-08-051-7/+0
| | | | | | | fork call. This eliminates a need for <iostream>. Also remove needless fsync calls. llvm-svn: 78131
* Use _exit rather than exit in the child process after a failed exec.Dan Gohman2009-08-051-3/+7
| | | | | | Add a comment explaining why. llvm-svn: 78128
* Follow Unix behavior and return 127 if the command is not found,Dan Gohman2009-08-041-1/+1
| | | | | | and 126 if it is not executable. llvm-svn: 78120
* When exec() fails, return 127 instead of errno; the parent process has no way toDaniel Dunbar2009-08-041-3/+3
| | | | | | | distinguish that the result is errno, so it can't use it to provide more information about the error (it also exposes the numeric value of errno). llvm-svn: 78098

* On "Unix", if Program::FindProgramByName is given a name containingDan Gohman2009-07-281-1/+1

* It isn't necessary to use F_OK when using R_OK or similar.Dan Gohman2009-07-281-2/+2
| | | | llvm-svn: 77392
* Fix a fixme; don't take binaries from the working directory.Benjamin Kramer2009-07-281-3/+3
| | | | | | | This fixes clang on non-darwin platforms if a file called 'ld' or 'as' is in the working directory. Based on patch by Pawel Worach! llvm-svn: 77379

* Make the JIT code emitter properly retry and ask for more memory when it runsReid Kleckner2009-07-232-6/+8
| | | | | | | | | | | | | out of memory, and also make the default memory manager allocate more memory when it runs out. Also, switch function stubs and global data over to using the BumpPtrAllocator. This makes it so the JIT no longer mmaps (or the equivalent on Windows) 16 MB of memory, and instead allocates in 512K slabs. I suspect this size could go lower, especially on embedded platforms, now that more slabs can be allocated. llvm-svn: 76828
* Remove duplication in Program::Execute{And,No}Wait.Mikhail Glushenkov2009-07-183-276/+91
