2010-03-26remove a constructor implementation that isn't declaredChris Lattner
in the header. How can both clang and gcc accept this? PR6703 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99658 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-17Fix a false-positive memory leak in code using RemoveFileOnSignal(). BecauseJeffrey Yasskin
libstdc++'s std::string class points to the interior of an allocation, valgrind reports strings still alive at program termination as possible leaks. I didn't use a ManagedStatic for this because System can't depend on Support. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98716 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-22Fix TimeValue::now() on Unix.Torok Edwin
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94178 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-16remove use of SmallVector from Path::makeUnique. Path::makeUniqueChris Lattner
is not used by anything performance sensitive, so just use std::string. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@91528 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-29This patch ensures that Path::GetMainExecutable is able to handle theKovarththanan Rajaratnam
case where realpath() fails. When this occurs we segfault trying to create a std::string from a NULL pointer. Fixes PR5635. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90082 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-26Move DataTypes.h to include/llvm/System, update all users. This breaks the lastChandler Carruth
direct inclusion edge from System to Support. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85086 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-22Use 'waitpid' instead of 'wait'. Basing Program::Wait() on 'wait()' ↵Ted Kremenek
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84903 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-15Get rid of GetProcessId in Win32/Program.inc.Mikhail Glushenkov
GetProcessId was introduced only in XP. As a bonus, this change makes Program objects copyable, since Program is now basically a PID. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81826 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-11Fix llvm-extract's "writing bitcode to a terminal" warning, which wasn'tDan Gohman
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81568 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-23Prune #includes from llvm/Linker.h and llvm/System/Path.h,Chris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79869 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-04When exec() fails, return 127 instead of errno; the parent process has no way toDaniel Dunbar
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). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78098 91177308-0d34-0410-b5e6-96231b3b80d8
