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

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

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76828 91177308-0d34-0410-b5e6-96231b3b80d8

| * Eliminate the static constructors and locks from DynamicLibrary.cpp.Chris Lattner2009-07-071-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes PR4512 and eliminating static ctors is always good. Losing thread safety is unfortunate, but the code is just incredibly poorly designed. If someone is interested, the "right" solution is to split DynamicLibrary.cpp into two separate pieces: a stateless piece in libsystem, and a simple support file in libsupport that has the "state" (e.g. AddSymbol) in managed static objects. Doing this would both fix memory leaks we already have, as well as make the code thread safe again. it would also make sense to move all the unix specific code in System/DynamicLibrary.cpp into System/Unix/DynamicLibrary.inc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74927 91177308-0d34-0410-b5e6-96231b3b80d8
