Daniel re-educated me about what Alias does and does not do. Turn that off for '-fasm' and explicitly map from that flag to -fgnu-keywords in the driver. Turn off the driver in the lexer test for this madness and add a test to the driver that the translation actually works. llvm-svn: 104428

Make using '-fshort-enums' an error until it is actually implemented (changes the ABI, so it is dangerous to not error out if we don't support it). Fixes <rdar://problem/7461006>. llvm-svn: 91191

// CHECK_OPTIONS2: -fno-gnu-keywords
Use -fno-math-errno by default, and remove the IsMathErrnoDefault targethook, which is no longer being used. This fixes PR5971. llvm-svn: 92987

Tests: Fix some bugs in clang_f_opts, options were out of order but it worked because it had two inputs, except on Win32 where /dev/null doesn't exist. llvm-svn: 91235

There were some frustrating problems with the implementation of -Wwrite-strings. First and foremost, once the positive form of the flag was passed, it could never be disabled by passing -Wno-write-strings. Also, the diagnostic engine couldn't in turn use -Wwrite-strings to control diagnostics (as GCC does) because it was essentially hijacked to drive the language semantics. Fix this by giving CC1 a clean '-fconst-strings' flag to enable const-qualified strings in C and ObjC compilations. Corresponding '-fno-const-strings' is also added. Then the driver is taught to introduce '-fconst-strings' in the CC1 command when '-Wwrite-strings' dominates. This entire flag is basically GCC-bug-compatibility driven, so we also match GCC's bug where '-w' doesn't actually disable -Wwrite-strings. I'm open to changing this though as it seems insane. llvm-svn: 130051

Fix Clang's __DEPRECATED define to be controled by -Wdeprecated. This matches GCC behavior which libstdc++ uses to limit #warning-based messages about deprecation. The machinery involves threading this through a new '-fdeprecated-macro' flag for CC1. The flag defaults to "on", similarly to -Wdeprecated. We turn the flag off in the driver when the warning is turned off (modulo matching some GCC bugs). We record this as a language option, and key the preprocessor on the option when introducing the define. A separate flag rather than a '-D' flag allows us to properly represent the difference between C and C++ builds (only C++ receives the define), and it allows the specific behavior of following -Wdeprecated without potentially impacting the set of user-provided macro flags. llvm-svn: 130055

Move all of the logic for __DEPRECATED to the driver based on comments from dgregor. llvm-svn: 130066
