2009-03-08add some explicit llvm:: qualifiers to the unix side, fix problems on the ↵Chris Lattner
windows side. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66386 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-07When a crash signal is delivered do two things: remove all of ourChris Lattner
signal handlers to prevent reentrance on unrelated things (a sigabort where the handle bus errors) also, clear the signal mask so that the signal doesn't infinitely reissue.

2009-03-05move some code to gracefully handle the case when a handler crashes.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66171 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-04Add a new 'AddSignalHandler' function to Signals.h that allowsChris Lattner
arbitrary functions to be run when a crash happens. Delete RemoveDirectoryOnSignal as it is dead and has never had clients. Change PrintStackTraceOnErrorSignal to be implemented in terms of AddSignalHandler. I updated the Win32 versions of these APIs, but can't test them. If there are any problems, I'd be happy to fix them as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66072 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-19If an executable is run through a symlink, dladdr will return theChris Lattner
symlink. We really want the ultimate executable being run, not the symlink. This lets clang find its headers when invoked through a symlink. rdar://6602012 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65017 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-05Don't use plain %x to print pointer values. I had changed it from %pDan Gohman
since %p isn't formatted consistently, but obviously plain %x is wrong. PRIxPTR with a cast to uintptr_t would work here, but that requires inconvenient build-system changes. %lu works on all current and foreseable future hosts. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60616 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-20Update the stub and callback code to handle lazy compilation. The stubJim Grosbach
is re-written by the callback to branch directly to the compiled code in future invocations. Added back in range-based memory permission functions for the updating of the stub on Darwin. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57846 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-03On Darwin ARM, memory needs special handling to do JIT. This patch expandsJim Grosbach

2008-06-12Fix redirection of stderr in sys::Program::ExecuteAndWait. There was logicMatthijs Kooijman
error that caused it to redirect stderr to stdout too often. This fix is applied identically to the win32 code as well, but that is untested. --Thi line, and those below, will be ignored-- M System/Unix/Program.inc M System/Win32/Program.inc git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52233 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-12Make I/O redirection handling in sys::Program a bit more consistent. NoMatthijs Kooijman
functional changes. Win32 code is untested, but should work fine. In the unix variant, rename RedirectFD to RedirectIO and let that function handle empty and null paths instead of doing that in the caller 3 times. This is the same as win32 already does it. In the win32 variant, use Path::isEmpty() instead of checking the resulting c_str() manually. This is the same as unix already does it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52230 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-03Re-implemented Path::createDirectoryOnDisk (for Unix).Ted Kremenek
This method allows one to create a directory, and optionally create all parent directories that do not exist. The original implementation would require that *all* directories along a path are writable by the user, including directories that already exist. For example, suppose we wanted to create the directory "/tmp/foo/bar", and the directory "/tmp" already exists, but not "/tmp/foo". Since "/tmp" is writable by all users, the original implementation would work, and create "/tmp/foo", followed by "/tmp/bar". A problem occurred, however if one wanted to created the directory "/Users/myuser/bar" (or equivalently "/home/myuser/bar"), and "/Users/myuser" already existed and is writable by the current user. The directory "/User/myuser" is writable by the user, but "/User" is not. The original implementation of createDirectoryOnDisk would return with failure since "/User" is not writable, even though "/User/mysuser" is writable. The new implementation works by recursively creating parents as needed, and thus doesn't need to check the permissions on every directory in a path. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49162 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-01Remove MappedFile support for mapping files for write and execChris Lattner
and shared. This complicates the design, is not used, and probably doesn't even work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49022 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-01cleanup the MappedFile API and comments. This removes and updatesChris Lattner
tons of out of date comments (really nothing throws here!) and fixes some other fairly glaring issues: "size" used to return the size of the file *and* change it, depending on how you called it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49009 91177308-0d34-0410-b5e6-96231b3b80d8
