2009-03-20pass langoptions around.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67376 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-20pass LangOptions into TargetInfo::getTargetDefines, so that targetsChris Lattner
can have language-specific defines. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67375 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-03implement support for propagating *features* down to the code generatorChris Lattner
and defining target-specific macros based on them (like __SSE3__ and friends). After extensive discussion with Daniel, this work will need driver support, which will translate things like -msse3 into a -mattr feature. Until this work is done, the code in clang.cpp is disabled and the X86TargetInfo ctor still defaults to SSE2. With these two things changed, this code will work. PR3634 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65966 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-02Add plumbing to support programatically defining __SSE2__ and friends,Chris Lattner
even though we still hard code sse2 for now. No support for 3dnow or sse4a, but someone could add that if they desired. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65886 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-13Give TargetInfo a new IntPtrType to hold the intptr_t type forChris Lattner
a target. Make Preprocessor.cpp define a new __INTPTR_TYPE__ macro based on this. On linux/32, set intptr_t to int, instead of long. This fixes PR3563. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64495 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. Use -fblocks in the various testcases that use blocks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60563 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-02More fallout from r58501: primary fix is some more corrections to make Eli Friedman
the types for size_t and ptrdiff_t more accurate. I think all of these are correct, but please compare the defines for __PTRDIFF_TYPE__ and __SIZE_TYPE__ to gcc to double-check; this particularly applies to those on BSD variants, since I'm not sure what they do here; I assume here that they're the same as on Linux. Fixes wchar_t to be "int", not "unsigned int" (which I think is correct on everything but Windows). Fixes ptrdiff_t to be "int" rather than "short" on PIC16; "short" is an somewhat strange choice because it normally gets promoted, and it's not consistent with the choice for size_t. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58556 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-31Made the mechanism of defining preprocessor defs for maxint, ptrdiff_t, wcharSanjiv Gupta
etc more generic. For some targets, long may not be equal to pointer size. For example: PIC16 has int as i16, ptr as i16 but long as i32. Also fixed a few build warnings in assert() functions in CFRefCount.cpp, CGDecl.cpp, SemaDeclCXX.cpp and ParseDeclCXX.cpp. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58501 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-05move a bunch more integer sizing out of target-specific code intoChris Lattner
target indep code. Note that this changes functionality on PIC16: it defines __INT_MAX__ correctly for it, and it changes sizeof(long) to 16-bits (to match the size of pointer). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57132 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-21Remove duplicate define from Windows-x86 target.Eli Friedman

2008-08-21Initial implementation of Windows x86 target; at the moment, the only Eli Friedman
difference from generic x86 is the defines. The rest is non-trivial to implement. I'm not planning on adding any more targets myself; if there are any targets anyone is currently using that are missing, feel free to add them, or ask me to add them. This concludes the work I'm planning for the TargetInfo implementations at the moment; all the other issues with TargetInfo require some API changes, and I haven't really thought it through. Some of the remaining issues: allowing targets to define size_t and wchar_t properly, adding some sort of __builtin_type_info intrinsic so we can finish clang's limits.h and float.h and get rid of a massive number of macro definitions, allowing target-specific command-line options, allowing target-specific defaults for certain command-line options like -fms-extensions, exposing vector alignment outside of the description string, exposing endianness outside of the description string, allowing targets to expose special bit-field layout requirements, exposing some sort of custom hook for call generation in CodeGen, and adding CPU selection to control defines like __SSE__. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55098 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-21First cut at OS detection, taking advantage of the new generic targets. Eli Friedman
This approach allows adding OS-specific targets/defines/etc. without completely breaking unknown subtargets. No new subtargets yet, although I plan to add x86-Linux soon. Others can add targets that they use as needed; adding a new subtarget takes very little code. Also does some fixups for description strings; a lot of them were unspecified. I think all the ones I added are correct, but they're unverified; corrections are welcome. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55091 91177308-0d34-0410-b5e6-96231b3b80d8
