Nico Weber 4a603af6f2 Fix nested CrashRecoveryContexts with LLVM_ENABLE_THREADS=OFF, allow them. ... libclang uses a CrashRecoveryContext, and building a module does too. If a module gets built through libclang, nested CrashRecoveryContexts are used. They work fine with threads as things are stored in ThreadLocal variables, but in LLVM_ENABLE_THREADS=OFF builds the two recovery contexts would write to the same globals. To fix, keep active CrashRecoveryContextImpls in a list and have the global point to the innermost one, and do something similar for tlIsRecoveringFromCrash. Necessary (but not sufficient) for PR11974 and PR20325 http://reviews.llvm.org/D11770 llvm-svn: 244251		2015-08-06 19:21:25 +00:00
