* Implement -mno-sse: if SSE is disabled on x86-64, don't store XMM on stack forTorok Edwin2009-02-011-1/+1
| | | | | | var-args, and don't allow FP return values llvm-svn: 63495
* should have removed the + when manually applying a patch!Torok Edwin2009-01-251-2/+2
| | | | llvm-svn: 62973
* revert this patch for now, because Codegen does still want to generate SSE code,Torok Edwin2009-01-251-0/+4
| | | | | | for example in the case of va-args. XFAIL associated tests. llvm-svn: 62972
* If user explicitly asks not to use SSE, don't force it. This fixes LLVM part ↵Torok Edwin2009-01-251-2/+0
| | | | | | of PR3402. llvm-svn: 62967
* Add the private linkage.Rafael Espindola2009-01-151-2/+2
| | | | llvm-svn: 62279
* Atom and Core i7 do not have same model number after all.Evan Cheng2009-01-051-4/+3
| | | | llvm-svn: 61686
* Add Intel processors core i7 and atom.Evan Cheng2009-01-031-1/+2

* Fix PR3210: Detect more Intel processors. Patch by Torok Edwin.Evan Cheng2009-01-031-2/+15

* Do not isel load folding bt instructions for pentium m, core, core2, and AMD ↵Evan Cheng2009-01-021-11/+25
| | | | | | processors. These are significantly slower than a load followed by a bt of a register. llvm-svn: 61557
* Fix x86 CPU id detection to identify Penryn (and future processors).Evan Cheng2009-01-021-2/+11
| | | | llvm-svn: 61556
* Add initial support for back-scheduling address computations,Dan Gohman2008-12-161-0/+11
| | | | | | | especially in the case of addresses computed from loop induction variables. llvm-svn: 61075
* 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
| | | | llvm-svn: 56888
* 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
* x86-64 PIC JIT fixes: do not generate the extra load for external GV's.Evan Cheng2008-07-161-1/+2

* 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

* Use a dedicated IsLinux flag instead of an ELFLinux TargetType.Dan Gohman2008-05-051-2/+5

* 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
