* CrashRecovery/Darwin: On Darwin, raise sends a signal to the main thread insteadDaniel Dunbar2010-08-191-0/+34
| | | | | | | | | 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

* Factor out the handler work from SignalHandler into a helper function,Dan Gohman2010-05-271-5/+12
| | | | | | | | | | 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
