* Re-apply 60689 now my head is screwed on right.Evan Cheng2008-12-081-0/+2
| | | | llvm-svn: 60711
* Revert 60689. It caused many regressions on Darwin targets.Dan Gohman2008-12-081-3/+1
| | | | llvm-svn: 60705
* Perform cheap checks first.Evan Cheng2008-12-081-1/+3
| | | | llvm-svn: 60689
* Make LoopStrengthReduce smarter about hoisting things out ofDale Johannesen2008-12-051-1/+17
| | | | | | | | | | | loops when they can be subsumed into addressing modes. Change X86 addressing mode check to realize that some PIC references need an extra register. (I believe this is correct for Linux, if not, I'm sure someone will tell me.) llvm-svn: 60608
* Re-did 60519. It turns out Darwin's handling of hidden visibility symbols ↵Evan Cheng2008-12-051-4/+8
| | | | | | are a bit more complicate than I expected. Both declarations and weak definitions still need a stub indirection. However, the stubs are in data section and they contain the addresses of the actual symbols. llvm-svn: 60571
* Temporarily revert r60519. It was causing a bootstrap failure:Bill Wendling2008-12-041-3/+0

* Fix command-line option printing to print two spaces where needed,Dan Gohman2008-10-141-2/+2
| | | | | | | | | 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. llvm-svn: 57521
* Just don't transform this memset into "bzero" if no-builtin is specified.Bill Wendling2008-09-301-2/+2

* Add the new `-no-builtin' flag. This flag is meant to mimic the GCCBill Wendling2008-09-301-8/+6
| | | | | | | | | `-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. llvm-svn: 56885

* Don't use the GOT for symbols that are not externally visible.Rafael Espindola2008-06-021-3/+6
| | | | llvm-svn: 51865
* Add CommonLinkage; currently tentative definitionsDale Johannesen2008-05-141-0/+1
| | | | | | | | | | 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. llvm-svn: 51118

* Add AsmPrinter support for emitting a directive to declare thatDan Gohman2008-05-051-0/+5
| | | | | | | | | the code being generated does not require an executable stack. Also, add target-specific code to make use of this on Linux on x86. llvm-svn: 50634

* Make ARM an X86 memcpy expansion more similar to each other.Rafael Espindola2007-10-311-1/+1
| | | | | | | | Now both subtarget define getMaxInlineSizeThreshold and the expansion uses it. This should not change generated code. llvm-svn: 43552
* Mac OS X X86-64 low 4G address not available.Evan Cheng2007-08-011-0/+4

* In the event that some really old non-Intel or -AMD CPU is encountered...Jeff Cohen2007-04-161-2/+5
| | | | llvm-svn: 36177
* Before assuming that the original code didn't work for Athlon64, the person whoJeff Cohen2007-04-161-6/+2
| | | | | | | 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. llvm-svn: 36173
* Add support for our first SSSE3 instruction "pmulhrsw".Bill Wendling2007-04-101-0/+1

* For PR1136: Rename GlobalVariable::isExternal as isDeclaration to avoidReid Spencer2007-01-301-2/+2
| | | | | | confusion with external linkage types. llvm-svn: 33663
* 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

* * 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
