* Cleanup code to use iterators instead of ".size()".Bill Wendling2009-07-281-21/+25

* Rip all of the global variable lowering logic out of TargetAsmInfo. SinceChris Lattner2009-07-285-25/+43
| | | | | | | | | | | | | | | | | | | | it is highly specific to the object file that will be generated in the end, this introduces a new TargetLoweringObjectFile interface that is implemented for each of ELF/MachO/COFF/Alpha/PIC16 and XCore. Though still is still a brutal and ugly refactoring, this is a major step towards goodness. This patch also: 1. fixes a bunch of dangling pointer problems in the PIC16 backend. 2. disables the TargetLowering copy ctor which PIC16 was accidentally using. 3. gets us closer to xcore having its own crazy target section flags and pic16 not having to shadow sections with its own objects. 4. fixes wierdness where ELF targets would set CStringSection but not CStringSection_. Factor the code better. 5. fixes some bugs in string lowering on ELF targets. llvm-svn: 77294

* Remove Value::{isName, getNameRef}.Daniel Dunbar2009-07-251-1/+1
| | | | | | Also, change MDString to use a StringRef. llvm-svn: 77098
* this is (unfortunately) several changes mixed together:Chris Lattner2009-07-251-1/+1
| | | | | | | | | | | | | | 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. llvm-svn: 77085
* Convert a few more things to use raw_ostream.Dan Gohman2009-07-252-26/+27
| | | | llvm-svn: 77039
* More migration to raw_ostream, the water has dried up around the iostream hole.Daniel Dunbar2009-07-2516-86/+101
| | | | | | | | | | - Some clients which used DOUT have moved to DEBUG. We are deprecating the "magic" DOUT behavior which avoided calling printing functions when the statement was disabled. In addition to being unnecessary magic, it had the downside of leaving code in -Asserts builds, and of hiding potentially unnecessary computations. llvm-svn: 77019
* Revert the ConstantInt constructors back to their 2.5 forms where possible, ↵Owen Anderson2009-07-246-44/+44

* "fix" PR4612, which is a crash on:Chris Lattner2009-07-231-1/+5
| | | | | | | | | | %0 = malloc [3758096384 x i32] The "malloc" instruction doesn't support 64-bits correctly (see PR715), and should be removed. Victor is actively working on fixing this, in the meantime just don't crash. llvm-svn: 76899
* Convert StringMap to using StringRef for its APIs.Daniel Dunbar2009-07-231-6/+3
| | | | | | | | | | | | - Yay for '-'s and simplifications! - I kept StringMap::GetOrCreateValue for compatibility purposes, this can eventually go away. Likewise the StringMapEntry Create functions still follow the old style. - NIFC. llvm-svn: 76888

* remove the SelectSectionForMachineConst hook, replacing it withChris Lattner2009-07-222-3/+10
| | | | | | | | a new getSectionForMergableConstant hook. This removes one dependence of TAI on Type, and provides the hook with enough info to make the right decision based on whether the global has relocations etc. llvm-svn: 76705
