2010-11-29Merge System into Support.Michael J. Spencer
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120298 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-16This is the first step in adding sane error handling support to LLVMSystem.Michael J. Spencer
The system API's will be shifted over to returning an error_code, and returning other return values as out parameters to the function. Code that needs to check error conditions will use the errc enum values which are the same as the posix_errno defines (EBADF, E2BIG, etc...), and are compatable with the error codes in WinError.h due to some magic in system_error. An example would be: if (error_code ec = KillEvil("Java")) { // error_code can be converted to bool. handle_error(ec); } git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119360 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-28Revert r117582, which reverted r77396. Searching PATH for a stringDan Gohman
which contains slashes is inconsistent with the meaning of PATH on Unix-type platforms, and pretty surprising. If the user has given a specific path to execute and we can't execute it, we should fail and say why. (Apparently the new posix_spawn code doesn't always say why, but that's a separate issue.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117596 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-28Revert r77396.Mikhail Glushenkov
Original commit message: On "Unix", if Program::FindProgramByName is given a name containing slashes, just go with it, regardless of whether it looks like it will be executable. This follows the behavior of sh(1) more closely. It's better when behaviour is consistent between platforms. This change also makes FindExecutable() behave as expected on unix-likes (before this commit, it used to always succeed). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117582 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-19CrashRecovery/Darwin: On Darwin, raise sends a signal to the main thread insteadDaniel Dunbar
of the current thread. This has the unfortunate effect that assert() and abort() will end up bypassing our crash recovery attempts. We work around this for anything in the same linkage unit by just defining our own versions of the assert handler and abort. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111583 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-27Factor out the handler work from SignalHandler into a helper function,Dan Gohman
and change llvm::sys::RunInterruptHandlers to call that function directly instead of calling SignalHandler, because the rest of SignalHandler invokes side effects which aren't appropriate, including raising the signal. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104896 91177308-0d34-0410-b5e6-96231b3b80d8
