John McCall c33dec3664 Add support for -Wwrite-strings. Patch by Mike M! Fixes PR 4804. 
llvm-svn: 98541
 2010-03-15 10:54:44 +00:00
John McCall d4324148d7 Re-introduce the ctor/dtor alias optimization, this time hidden behind a 
command-line option which defaults off.

John McCall bb79b5f6f3 Raise the responsibility for passing -disable-llvm-verifier in NDEBUG builds 
to the driver, and support it in CodeGenOptsToArgs().  Note that this changes
the default behavior of clang -cc1 to always run the verifier.

 2010-02-13 03:50:24 +00:00
John McCall cfcb775b56 Add an option to disable the LLVM verifier pass (which is still always 
disabled in NDEBUG builds).  The option applies only to -cc1 invocations and is:
  -disable_llvm_verifier

Anders Carlsson 5d40c6f658 Check in the beginnings of my new vtable layout builder idea. 
Right now, it's off by default but can be tested by passing -fdump-vtable-layouts to clang -cc1. This option will cause all vtables that will normally be emitted as part of codegen to also be dumped using the new layout code.

I've also added a very simple new vtable layout test case.

Daniel Dunbar 925152c2d0 clang -cc1: Add -fsjlj-exceptions, which requires far too much button pushing. 
llvm-svn: 95785
 2010-02-10 18:48:44 +00:00
Fariborz Jahanian 4587803919 Implement synthesizing properties by default. 
This is a non-fragile-abi feature only. Since it
breaks existing code, it is currently placed under
-fobjc-nonfragile-abi2 option for test purposes only
until further notice. WIP.

Douglas Gregor 62d311fdf4 Introduce a testbed for merging multiple ASTs into a single AST 
context with the AST importer. WIP, still useless but at least it has
a test.

Anders Carlsson fcd764a168 Add support for threadsafe statics, and make them the default (matching gcc). 
Daniel, I'd appreciate a review of the driver/cc1 parts.

Daniel Dunbar 92db0fbe5a clang -cc1: Wire up -emit-obj, for emitting object files. 
llvm-svn: 95182

Daniel Dunbar 2e3f2c805e Driver/Frontend: Add support for -fobjc-legacy-dispatch, not yet used. 
llvm-svn: 95004

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.

Dan Gohman d1e76b957b Use -fno-math-errno by default, and remove the IsMathErrnoDefault 
targethook, which is no longer being used. This fixes PR5971.

Daniel Dunbar a7d0231b66 clang -cc1: Rename -mcpu to -target-cpu to match other target options and not alias driver/backend option. 
llvm-svn: 91671
 2009-12-18 06:30:12 +00:00
Daniel Dunbar 24c7f5efc5 Add -dwarf-debug-flags, which provides a way to embed the cc1 level options used 
to compile a translation unit into the debug info for that file.
 - Used by parts of Darwin build process to check compiler flags, etc.
 - <rdar://problem/7256886> clang does not emit AT_APPLE_flags

Nuno Lopes 13c88c7269 implement PR5654: add -fassume-sane-operator-new, which is enabled by default, and adds the malloc attribute to the global function new() and to the overloaded new operators. 
feel free to chage the name to this lengthy argument

llvm-svn: 91543
 2009-12-16 16:59:22 +00:00
Daniel Dunbar a5a166d01a Add -resource-dir to clang -cc1, this allows the base directory for compiler 
resources (e.g., /usr/lib/clang/1.1) to be passed on the command line instead of
computed.

Jeffrey Yasskin 1615d45daa Un-namespace-qualify llvm_unreachable. It's a macro, so the qualification gave 
no extra safety anyway.

Mike Stump d954638f02 Implement runtime checks for undefined behavior. WIP. 
This implements a new flag -fcatch-undefined-behavior.  The flag turns
on additional runtime checks for:

  T a[I];

  a[i]    abort when i < 0 or i >= I.

Future stuff includes shifts by >= bitwidth amounts.

Daniel Dunbar a1b02a2380 Move LLVM backend options to explicit clang-cc / clang -cc1 options, which we then manually pass to the command line library; eventually the latter grossness should be fixed by a real API when creating the target machine. 
llvm-svn: 90063
 2009-11-29 07:18:39 +00:00

Daniel Dunbar da9e8e225d clang-cc: Remove some more llvm:🆑:init arguments, by only setting values when 
the argument is given.

Also, tweak Opt.Sysroot defaulting.

llvm-svn: 89074
 2009-11-17 09:15:57 +00:00

llvm-svn: 89058
 2009-11-17 07:07:28 +00:00
Daniel Dunbar 629f6bb95d Add initial cut at CompilerInvocation::toArgs, which "serializes" the CompilerInvocation into a list of arguments which can be passed to clang-cc (eventually, clang -cc1). 
- Unfortunately, this is currently a tedious and manual translation. Eventually it would be nice to automatically generate this code.
