'-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.

short name of the tool in use, instead of the name of the action that created
the command. The practical impact is we now get:
clang: error: clang frontend command failed due to signal 6 (use -v to see invocation)
instead of:
clang: error: assembler command failed due to signal 6 (use -v to see invocation)
when clang crashes on a job that uses the integrated assembler.

print out all of the category numbers with their description. This is useful
for clients that want to map the numbers produced by
--fdiagnostics-show-category=id to their human readable string form. The
output is simple but utilitarian:
$ clang --print-diagnostic-categories
1,Format String
2,Something Else
This implements rdar://7928193

over choice of:
t.c:3:11: warning: conversion specifies type 'char *' but the argument has type 'int' [-Wformat]
t.c:3:11: warning: conversion specifies type 'char *' but the argument has type 'int' [-Wformat,1]
t.c:3:11: warning: conversion specifies type 'char *' but the argument has type 'int' [-Wformat,Format String]
dox to come.

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.

- 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.
llvm-svn: 102255
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.

implemented precisely the same as GCC, but the distinction GCC makes isn't
useful to represent. This allows parsing code which uses GCC-specific keywords
('asm', etc.) without parsing in a fully GNU mode.

- 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.

means it isn't really possible to write the test case for this code, but this is
the kind of thing that really requires testing against the installed compiler
anyway.

Clang is installed. This is designed to match gcc, and is important when
installed in a non-standard location.
- This is gross, but no worse than ever. It will die when we finally move to
the compiler-rt based toolchain, any day now.
llvm-svn: 100915
Remove -faccess-control from -cc1; add -fno-access-control.
Make the driver pass -fno-access-control by default.
Update a bunch of tests to be correct under access control.

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.

deciding when we need to emit an extra "command failed" diagnostic.
- This also fixes the case where we were emitting that extra diagnostics, even
when using clang w/ the integrated assembler, which has good diagnostics.
