2009-06-28Add stack protector support to clang. This generates the 'ssp' and 'sspreq'Bill Wendling
function attributes. There are predefined macros that are defined when stack protectors are used: __SSP__=1 with -fstack-protector and __SSP_ALL__=2 with -fstack-protector-all. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74405 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-22This patch adds support for sender-aware dispatch in Objective-C for the GNU ↵Fariborz Jahanian
runtime, when compiled with -fobjc-sender-dependent-dispatch. This is used in AOP, COP, implementing object planes, and a few other things. Patch by David Chisnall. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72275 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-07Remove -fobjc-tight-layout, seems to work!Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71184 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-04Add -fobjc-tight-layout.Daniel Dunbar
- This implements gcc style Objective-C interface layout (I think). Currently it is always off, there is no functionality change unless this is passed. For the curious, the deal is that gcc lays out the fields of a subclass as if they were part of the superclass. That is, the subclass fields immediately follow the super class fields instead of being padded to the alignment of the superclass structure. - Currently gcc uses the tight layout in 32-bit and 64-bit modes, and llvm-gcc uses it in 32-bit only, for reasons which aren't clear yet. We probably want to switch to matching gcc, once this makes it through testing... my hope is that we can also fix llvm-gcc in order to maintain compatibility between the compilers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70827 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-08More fixes to builtin preprocessor defines.Daniel Dunbar
- Add -static-define option driver can use when __STATIC__ should be defined (instead of __DYNAMIC__). - Don't set __OPTIMIZE_SIZE__ on Os, __OPTIMIZE_SIZE__ is tied to Oz. - Set __NO_INLINE__ following GCC 4.2. - Set __GNU_GNU_INLINE__ or __GNU_STDC_INLINE__ following GCC 4.2. - Set __EXCEPTIONS for Objective-C NonFragile ABI. - Set __STRICT_ANSI__ for standard conforming modes. - I added a clang style test case in utils for this, but its not particularly portable and I don't think it belongs in the test suite. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68621 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-08Make debug info work when using -save-temps.Daniel Dunbar
- This is pretty ugly, but the most obvious solution. Chime in if you have a nicer one. - The problem is that with -save-temps, clang-cc has no idea what the name of the original input file is. However, the user expects to be able to set breakpoints based on the input file name. - We support this by providing a new option -main-file-name (similar to -dumpbase used by gcc) which allows the driver to pass in the original file name. - <rdar://problem/6753383> building with clang using --save-temps gets the compile unit name from the .i file... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68595 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-08Set __PIC__ (more) correctly.Daniel Dunbar
- Add -pic-level clang-cc option to specify the value for the define, updated driver to pass this. - Added __pic__ - Added OBJC_ZEROCOST_EXCEPTIONS define while I was here (to match gcc). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68584 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-02Fixup -ftrapv to be more gcc compatible. -ftrapu (for want of aMike Stump
better name) is the option that SmallTalk can use to intercept all overflows, including unsigned. I added some testcases so we don't break anything. Also included is another patch from David for += and friends. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68267 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-13introduce a new -fheinous-gnu-extensions flag that enables reallyChris Lattner
really horrible extensions that are disabled by default but that can be accepted by -fheinous-gnu-extensions (but which always emit a warning when enabled). As our first instance of this, implement PR3788/PR3794, which allows non-lvalues in inline asms in contexts where lvalues are required. bleh. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66910 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-10Limit the template instantiation depth to some user-configurable valueDouglas Gregor
(default: 99). Beyond this limit, produce an error and consider the current template instantiation a failure. The stack we're building to track the instantiations will, eventually, be used to produce instantiation backtraces from diagnostics within template instantiation. However, we're not quite there yet. This adds a new Clang driver option -ftemplate-depth=NNN, which should eventually be generated from the GCC command-line operation -ftemplate-depth-NNN (note the '-' rather than the '='!). I did not make the driver changes to do this mapping. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66513 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-16Support IRgen of sqrt -> llvm.sqrt, pow -> llvm.pow.Daniel Dunbar
- Define pow[lf]?, sqrt[lf]? as builtins. - Add -fmath-errno option which binds to LangOptions.MathErrno - Add new builtin flag Builtin::Context::isConstWithoutErrno for functions which can be marked as const if errno isn't respected for math functions. Sema automatically marks these functions as const when they are defined, if MathErrno=0. - IRgen uses const attribute on sqrt and pow library functions to decide if it can use the llvm intrinsic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64689 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-04instead of forcing blocks on by default, make them default to off, but letChris Lattner
specific targets default them to on. Default blocks to on on 10.6 and later. Add a -fblocks option that allows the user to override the target's default.
