2007-10-31Make ARM an X86 memcpy expansion more similar to each other.Rafael Espindola
Now both subtarget define getMaxInlineSizeThreshold and the expansion uses it. This should not change generated code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43552 91177308-0d34-0410-b5e6-96231b3b80d8

2007-04-16In the event that some really old non-Intel or -AMD CPU is encountered...Jeff Cohen

2007-04-16Before assuming that the original code didn't work for Athlon64, the person whoJeff Cohen
replaced it with a FIXME should have determined what did work. Then he would have realized that the code was in fact correct, and would have avoided breaking it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@36173 91177308-0d34-0410-b5e6-96231b3b80d8

2007-01-28Propagate changes from my local tree. This patch includes:Anton Korobeynikov
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33597 91177308-0d34-0410-b5e6-96231b3b80d8

2007-01-17* Fix one more bug in PIC codegen: extra load is needed for *all*Anton Korobeynikov
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33299 91177308-0d34-0410-b5e6-96231b3b80d8

2007-01-03Really big cleanup.Anton Korobeynikov
- 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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32833 91177308-0d34-0410-b5e6-96231b3b80d8
