2011-04-23Fix Clang's __DEPRECATED define to be controled by -Wdeprecated. ThisChandler Carruth
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130055 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-23There were some frustrating problems with the implementation ofChandler Carruth
-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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130051 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-22Add -fdelayed-template-parsing option. Using this option all templated ↵Francois Pichet
function definitions are parsed at the end of the translation unit only if it is required by an actual instantiation. As such all the symbols of the TU are available during name lookup. Using this flag is necessary for compatibility with Microsoft template code. This also provides some parsing speed improvement. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130022 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-21Wire up the -ftest-coverage and -fprofile-arcs flags to .gcno file emission (atNick Lewycky
compile time) and .gcda emission (at runtime). --coverage enables both. This does not yet add the profile_rt library to the link step if -fprofile-arcs is enabled when linking. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129956 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-09refactor -ccc-gcc-name codeDylan Noblesmith
Put the logic for deciding the default name for gcc/g++ in the only place that actually cares about it.

2011-03-27Add an option to suppress include stack printing on note diagnostics.Chandler Carruth
These stacks are often less important than those on primary diagnostics. As the number of notes grows, this becomes increasingly important. The include stack printing is clever and doesn't print stacks for adjacent diagnostics from the same file, but when a note is in between a sequence of errors in a header file, and the notes all refer to some other file, we end up getting a worst-case ping-pong of include stacks that take up a great deal of vertical space. Still, for now, the default behavior isn't changed. We can evaluate user feedback with the flag. Patch by Richard Trieu, a couple of style tweaks from me. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128371 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-27Add -f[no-]strict-overflow to the Clang driver. Use it to set theChandler Carruth
default for -fwrapv if that flag isn't specified explicitly. We always prefer an explict setting of -fwrapv when present. Also adds support for -fno-wrapv to allow disabling -fwrapv even when -fno-strict-overflow is passed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128353 91177308-0d34-0410-b5e6-96231b3b80d8
