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

2009-07-23Make the JIT code emitter properly retry and ask for more memory when it runsReid Kleckner
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

2009-07-07Eliminate the static constructors and locks from DynamicLibrary.cpp.Chris Lattner
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
