[libclang] Fix crash when a #pragma diagnostic is included in the preamble. A PCH file keeps track of #pragma diagnostics state; when loading the preamble, they conflicted with the #pragma diagnostic state already present in the DiagnosticsEngine object due to parsing the preamble. Fix this by clearing the state of the DiagnosticsEngine object. Fixes rdar://10363572 && http://llvm.org/PR11254. llvm-svn: 143644 2011-11-04 04:28:19 +08:00			`#pragma clang diagnostic ignored "-Wtautological-compare"`
[PCH] Fix reading from PCH of diagnostic pragmas. In certain cases ASTReader would call the normal DiagnosticsEngine API to initialize the state of diagnostic pragmas but DiagnosticsEngine would try to compare source locations leading to crash because the main FileID was not yet initialized. Yet another case of the ASTReader trying to use the normal APIs and inadvertently breaking invariants. Fix this by having the ASTReader set up the internal state directly. llvm-svn: 144153 2011-11-09 09:24:17 +08:00			`#include "pragma_disable_warning.h"`
For Diagnostic::Reset() also reset the state related to #pragma diagnostic. Fixes rdar://9170766. llvm-svn: 128346 2011-03-27 02:58:17 +08:00
