are explicitly given.

Douglas Gregor 8ed0c0b99d Introduce -f{no-}spell-checking options to enable/disable 
spell-checking. By default, spell-checking is enabled for Clang
(obviously) but disabled in CIndex for performance reasons.

Chris Lattner 51924e517b Implement support for -fwrapv, rdar://7221421 
As part of this, pull together trapv handling into the same enum.

This also add support for NSW multiplies.

This also makes PCH disagreement on overflow behavior silent, since it
really doesn't matter except for warnings and codegen (no macros get 
defined etc).

Jeffrey Yasskin 2b99c6fc4f Add an option -fshow-overloads=best|all to limit the number of overload 
candidates printed.  We default to 'all'.  At the moment, 'best' prints only
the first 4 overloads, but we'll improve that over time.

Daniel Dunbar 24e52992c0 Driver: Support invoking Clang on .ll or .bc inputs. 
- We actually pretend that we have two separate types for LLVM assembly/bitcode because we need to use the standard suffixes with LTO ('clang -O4 -c t.c' should generate 't.o').

It is now possible to do something like:
  $ clang -emit-llvm -S t.c -o t.ll ... assorted other compile flags ...
  $ clang -c t.ll -o t.o ... assorted other compile flags ...
and expect that the output will be almost* identical to:
  $ clang -c t.c -o t.o ... assorted other compile flags ...
because all the target settings (default CPU, target features, etc.) will all be initialized properly by the driver/frontend.

*: This isn't perfect yet, because in practice we will end up running the optimization passes twice. It's possible to get something equivalent out with a well placed -mllvm -disable-llvm-optzns, but I'm still thinking about the cleanest way to solve this problem more generally.

Daniel Dunbar 6beaf5110f Driver/Darwin: Model dsymutil properly, as a separate action/tool kind which is 
added as the last output step, instead of just hacking it into the link step.
 - Among other things, this fixes dSYM generation when using multiple -arch options.

Chandler Carruth e039148801 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.

Chris Lattner bf6fac8415 add a new -fdiagnostics-show-category=none/id/name option, giving control 
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.

llvm-svn: 103056
 2010-05-04 21:55:25 +00:00
Douglas Gregor cd121fb013 Introduce a limit on the depth of the macro instantiation backtrace 
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.

Daniel Dunbar fca18c1b41 NeXT: Clean up dispatch method policy selection. 
- 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: 102254
 2010-04-24 17:56:39 +00:00
Douglas Gregor ffed1cb339 Introduce a limit on the depth of the template instantiation backtrace 
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.

Chandler Carruth e03aa55bfd Add support for '-fgnu-keywords' and '-fasm' to Clang's driver. They are not 
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.

Daniel Dunbar 76fa840d09 Driver/Frontend: Add support for -mllvm, which forwards options to the LLVM 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.

 2010-04-08 15:44:22 +00:00
Chris Lattner b35583df52 add a new driver-level -ferror-limit=412 option, which causes clang to stop 
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.

Blaine Garst fc83aa04db Unconditionally support block introspection data in a new field at the end 
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.

Benjamin Kramer 842bf17366 Use StringRef instead of returning a temporary std::string. 
This fixes a really nasty bug in Darwin::getDarwinArchName where we were going
StringRef -> temporary std::string -> StringRef (and return the dead StringRef).
The StringRefs from Triple live as long as the Triple itself, that should be
long enough.

Hopefully 2 of 4 MSVC buildbot failures are gone now.

Douglas Gregor ac0605e927 Introduce serialization and deserialization of diagnostic information 
so that CIndex can report diagnostics through the normal mechanisms
even when executing Clang in a separate process. This applies both
when performing code completion and when using ASTs as an intermediary
for clang_createTranslationUnitFromSourceFile().

The serialized format is not perfect at the moment, because it does
not encapsulate macro-instantiation information. Instead, it maps all
source locations back to the instantiation location. However, it does
maintain source-range and fix-it information. To get perfect fidelity
from the serialized format would require serializing a large chunk of
the source manager; at present, it isn't clear if this code will live
long enough for that to matter.
