2010-05-04Introduce a limit on the depth of the macro instantiation backtraceDouglas Gregor
printed in a diagnostic, similar to the limit we already have on the depth of the template instantiation backtrace. The macro instantiation backtrace is limited to 10 "instantiated from:" diagnostics; when it's longer than that, we'll show the first half, then say how many were suppressed, then show the second half. The limit can be changed with -fmacro-instantiation-limit=N, and turned off with N=0. This eliminates a lot of note spew with libraries making use of the Boost.Preprocess library. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103014 91177308-0d34-0410-b5e6-96231b3b80d8

- Replace -cc1 level -fobjc-legacy-dispatch with -fobjc-dispatch-method={legacy,non-legacy,mixed}. - Lift "mixed" vs "non-mixed" policy choice up to driver level, instead of being buried in CGObjCMac.cpp. - No intended functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102255 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-20Introduce a limit on the depth of the template instantiation backtraceDouglas Gregor
we will print with each error that occurs during template instantiation. When the backtrace is longer than that, we will print N/2 of the innermost backtrace entries and N/2 of the outermost backtrace entries, then skip the middle entries with a note such as: note: suppressed 2 template instantiation contexts; use -ftemplate-backtrace-limit=N to change the number of template instantiation entries shown This should eliminate some excessively long backtraces that aren't providing any value. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101882 91177308-0d34-0410-b5e6-96231b3b80d8

implemented precisely the same as GCC, but the distinction GCC makes isn't useful to represent.

2010-04-15Driver/Frontend: Add support for -mllvm, which forwards options to the LLVM ↵Daniel Dunbar
option parser. - Note that this is a behavior change, previously -mllvm at the driver level forwarded to clang -cc1. The driver does a little magic to make sure that '-mllvm -disable-llvm-optzns' works correctly, but other users will need to be updated to use -Xclang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101354 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-07add a new driver-level -ferror-limit=412 option, which causes clang to stopChris Lattner
emitting diagnostics after it has produced that many errors. Give this a default value of 20 which produces plenty of errors for people to fix before recompiling but not so many that their entire console scrolls away when the compiler gets confused. The experience looks like this: $ clang foo.c <tons of crap> foo.c:102:3: error: unknown type name 'somethingbad' somethingbad x; ^ fatal error: too many errors emitted, stopping now 36 warnings and 20 errors generated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100689 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-23Unconditionally support block introspection data in a new field at the endBlaine Garst
of the block descriptor field. This field is the ObjC style @encode signature of the implementation function, and was to this point conditionally provided in the block literal data structure. That provisional support is removed. Additionally, eliminate unused enumerations for the block literal flags field. The first shipping ABI unconditionally set (1<<29) but this bit is unused by the runtime, so the second ABI will unconditionally have (1<<30) set so that the runtime can in fact distinguish whether the additional data is present or not. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96989 91177308-0d34-0410-b5e6-96231b3b80d8
