* Propagate changes from my local tree. This patch includes:Anton Korobeynikov2007-01-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | 1. New parameter attribute called 'inreg'. It has meaning "place this parameter in registers, if possible". This is some generalization of gcc's regparm(n) attribute. It's currently used only in X86-32 backend. 2. Completely rewritten CC handling/lowering code inside X86 backend. Merged stdcall + c CCs and fastcall + fast CC. 3. Dropped CSRET CC. We cannot add struct return variant for each target-specific CC (e.g. stdcall + csretcc and so on). 4. Instead of CSRET CC introduced 'sret' parameter attribute. Setting in on first attribute has meaning 'This is hidden pointer to structure return. Handle it gently'. 5. Fixed small bug in llvm-extract + add new feature to FunctionExtraction pass, which relinks all internal-linkaged callees from deleted function to external linkage. This will allow further linking everything together. NOTEs: 1. Documentation will be updated soon. 2. llvm-upgrade should be improved to translate csret => sret. Before this, there will be some unexpected test fails. llvm-svn: 33597
* Linux GOT indirect reference is only necessary in PIC mode.Evan Cheng2007-01-221-1/+1
| | | | llvm-svn: 33441
* * Fix one more bug in PIC codegen: extra load is needed for *all*Anton Korobeynikov2007-01-171-1/+5
| | | | | | | | | non-statics. * Introduce new option to output zero-initialized data to .bss section. This can reduce size of binaries. Enable it by default for ELF & Cygwin/Mingw targets. Probably, Darwin should be also added. llvm-svn: 33299
* * PIC codegen for X86/Linux has been implementedAnton Korobeynikov2007-01-121-7/+8
| | | | | | | | * PIC-aware internal structures in X86 Codegen have been refactored * Visibility (default/weak) has been added * Docs fixes (external weak linkage, visibility, formatting) llvm-svn: 33136
* Really big cleanup.Anton Korobeynikov2007-01-031-4/+8
| | | | | | | | | | | - New target type "mingw" was introduced - Same things for both mingw & cygwin are marked as "cygming" (as in gcc) - .lcomm is supported here, so allow LLVM to use it - Correctly use underscored versions of setjmp & _longjmp for both mingw & cygwin llvm-svn: 32833
