2008-11-28Fix build with gcc-4.4: it doesn't like PICStyleDuncan Sands
being both a namespace and a variable name. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60208 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-14Fix command-line option printing to print two spaces where needed,Dan Gohman
instead of requiring all "short description" strings to begin with two spaces. This makes these strings less mysterious, and it fixes some cases where short description strings mistakenly did not begin with two spaces. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57521 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-30Just don't transform this memset into "bzero" if no-builtin is specified.Bill Wendling

2008-09-30Add the new `-no-builtin' flag. This flag is meant to mimic the GCCBill Wendling
`-fno-builtin' flag. Currently, it's used to replace "memset" with "_bzero" instead of "__bzero" on Darwin10+. This arguably violates the meaning of this flag, but is currently sufficient. The meaning of this flag should become more specific over time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56885 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-14Add CommonLinkage; currently tentative definitionsDale Johannesen
are represented as "weak", but there are subtle differences in some cases on Darwin, so we need both. The intent is that "common" will behave identically to "weak" unless somebody changes their target to do something else. No functional change as yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51118 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

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.
