* Fix TimeValue::now() on Unix.Torok Edwin2010-01-221-1/+1
| | | | | | | | | TimeValue()::now().toEpochTime() is supposed to be the same as time(), but it wasn't, because toEpoch subtracted PosixZeroTime, but now() didn't add PosixZeroTime! Add a unittest to check this works. llvm-svn: 94178

* Use 'waitpid' instead of 'wait'. Basing Program::Wait() on 'wait()' ↵Ted Kremenek2009-10-221-1/+1
| | | | | | | | | | | prevents it being correct within a multithreaded context. This address: PR 5277 (Program::Wait is unsafe to call from multiple threads). Note: If waitpid() turns out to be non-portable, we can add more autoconf magic, or look into another solution. llvm-svn: 84903

* Get rid of GetProcessId in Win32/Program.inc.Mikhail Glushenkov2009-09-151-18/+5
| | | | | | | 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
* Fix llvm-extract's "writing bitcode to a terminal" warning, which wasn'tDan Gohman2009-09-111-13/+7
| | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | 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

| | | | | | 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
