* Update Triple to use StringRef/Twine based APIs.Daniel Dunbar2009-07-263-108/+85
| | | | | | | - This is now shorter, simpler, safer, and more efficient, what a deal. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77119 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | and efficient on a StringRef. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77117 91177308-0d34-0410-b5e6-96231b3b80d8

* Kill Target specific ModuleMatchQuality stuff.Daniel Dunbar2009-07-2616-286/+13
| | | | | | | - This was overkill and inconsistently implemented. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77114 91177308-0d34-0410-b5e6-96231b3b80d8
* Add TargetRegistry::lookupTarget.Daniel Dunbar2009-07-268-107/+57
| | | | | | | | | | | | | | | - This is a simplified mechanism which just looks up a target based on the target triple, with a few additional flags. - Remove getClosestStaticTargetForModule, the moral equivalent is now: lookupTarget(Mod->getTargetTriple, true, false, ...); - This no longer does the fuzzy matching with target data (based on endianness and pointer width) that getClosestStaticTargetForModule was doing, but this was deemed unnecessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77111 91177308-0d34-0410-b5e6-96231b3b80d8

* finish simplifying DarwinTargetAsmInfo::SelectSectionForGlobalChris Lattner2009-07-263-23/+42
| | | | | | | | for now. Make the section switching directives more consistent by not including \n and including \t for them all. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77107 91177308-0d34-0410-b5e6-96231b3b80d8
* Some clients rely on getName{Start,End} not returning 0, even if the length isDaniel Dunbar2009-07-261-2/+8

* simplify DarwinTargetAsmInfo::SelectSectionForGlobal a bitChris Lattner2009-07-262-16/+37
| | | | | | | | | | | | | and make it more aggressive, we now put: const int G2 __attribute__((weak)) = 42; into the text (readonly) segment like gcc, previously we put it into the data (readwrite) segment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77104 91177308-0d34-0410-b5e6-96231b3b80d8
* simplify some predicates, add isMergableString()Chris Lattner2009-07-261-12/+10
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77103 91177308-0d34-0410-b5e6-96231b3b80d8
* Simplify.Daniel Dunbar2009-07-261-12/+5
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77102 91177308-0d34-0410-b5e6-96231b3b80d8
* Add support for ARM Neon VREV instructions.Bob Wilson2009-07-264-0/+214
| | | | | | | Patch by Anton Korzh, with some modifications from me. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77101 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove Value::setName(const char*, unsigned).Daniel Dunbar2009-07-264-12/+15
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77100 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove Value::setName(const char*).Daniel Dunbar2009-07-262-8/+1
| | | | | | | | | - Split into a separate patch because there is a slight functionality change, it is no longer valid to call setName(0), which was equivalent to setName(""). I'm hoping no one depends on this... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77099 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove Value::{isName, getNameRef}.Daniel Dunbar2009-07-2515-71/+49
| | | | | | | Also, change MDString to use a StringRef. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77098 91177308-0d34-0410-b5e6-96231b3b80d8

* this is (unfortunately) several changes mixed together:Chris Lattner2009-07-2514-89/+100
| | | | | | | | | | | | | | | | | 1. Spell SectionFlags::Writeable as "Writable". 2. Add predicates for deriving SectionFlags from SectionKinds. 3. Sink ELF-specific getSectionPrefixForUniqueGlobal impl into ELFTargetAsmInfo. 4. Fix SectionFlagsForGlobal to know that BSS/ThreadBSS has the BSS bit set (the real fix for PR4619). 5. Fix isSuitableForBSS to not put globals with explicit sections set in BSS (which was the reason #4 wasn't fixed earlier). 6. Remove my previous hack for PR4619. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77085 91177308-0d34-0410-b5e6-96231b3b80d8

* add the most expedient hack to fix PR4619, along with a testcase.Chris Lattner2009-07-252-0/+13
| | | | | | | Thanks to Rafael for the great example. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77083 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix a few comments to say "backedge-taken count" instead ofDan Gohman2009-07-251-2/+3
| | | | | | | "trip count". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77081 91177308-0d34-0410-b5e6-96231b3b80d8

* When attempting to sign-extend an addrec by interpretingDan Gohman2009-07-252-2/+76
| | | | | | | | the step value as unsigned, the start value and the addrec itself still need to be treated as signed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77078 91177308-0d34-0410-b5e6-96231b3b80d8

* Simplify JIT target selection.Daniel Dunbar2009-07-2517-156/+58
| | | | | | | | | | | - Instead of requiring targets to define a JIT quality match function, we just have them specify if they support a JIT. - Target selection for the JIT just gets the host triple and looks for the best target which matches the triple and has a JIT. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77060 91177308-0d34-0410-b5e6-96231b3b80d8

* remove this test. It is currently failing because we now emit the stringChris Lattner2009-07-251-11/+0
| | | | | | | | | on darwin with ".cstring" instead of ".section __TEXT,__cstring". They are the same and the former is better. Remove this because this is no longer magic pixie dust in the frontend. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77055 91177308-0d34-0410-b5e6-96231b3b80d8

* Initial update to VMCore to use Twines for string arguments.Daniel Dunbar2009-07-2519-276/+392
| | | | | | | | - The only meat here is in Value.{h,cpp} the rest is essential 'const std::string &' -> 'const Twine &'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77048 91177308-0d34-0410-b5e6-96231b3b80d8
