* Remove Value::setName(const char*).Daniel Dunbar2009-07-261-7/+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| | | | | | | | | - Split into a separate patch because there is a slight functionality change, it is no longer valid to call setName(0), which was equivalent to setName("").

* this is (unfortunately) several changes mixed together:Chris Lattner2009-07-2511-81/+72
| | | | | | | | | | | | | | | | | 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

* Simplify JIT target selection.Daniel Dunbar2009-07-2516-145/+48
| | | | | | | | | | | - 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

* Instead of eagerly creating new SCEVs to replace all SCEVs that areDan Gohman2009-07-251-103/+56
| | | | | | | | | | | | | affected after a PHI node has been analyzed, just remove affected SCEVs from the Scalars map, so that they'll be (lazily) recreated as needed. This avoids creating SCEV objects that aren't actually needed. Also, rewrite the associated def-use walking code to be non-recursive and to continue traversing past Instructions that don't have an entry in the Scalars map. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77032 91177308-0d34-0410-b5e6-96231b3b80d8

* Change Thumb2 jumptable codegen to one that uses two level jumps:Evan Cheng2009-07-2512-72/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before: adr r12, #LJTI3_0_0 ldr pc, [r12, +r0, lsl #2] LJTI3_0_0: .long LBB3_24 .long LBB3_30 .long LBB3_31 .long LBB3_32 After: adr r12, #LJTI3_0_0 add pc, r12, +r0, lsl #2 LJTI3_0_0: b.w LBB3_24 b.w LBB3_30 b.w LBB3_31 b.w LBB3_32 This has several advantages. 1. This will make it easier to optimize this to a TBB / TBH instruction + (smaller) table. 2. This eliminate the need for ugly asm printer hack to force the address into thumb addresses (bit 0 is one). 3. Same codegen for pic and non-pic. 4. This eliminate the need to align the table so constantpool island pass won't have to over-estimate the size. Based on my calculation, the later is probably slightly faster as well since ldr pc with shifter address is very slow. That is, it should be a win as long as the HW implementation can do a reasonable job of branch predict the second branch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77024 91177308-0d34-0410-b5e6-96231b3b80d8
* More migration to raw_ostream, the water has dried up around the iostream hole.Daniel Dunbar2009-07-2545-256/+302
| | | | | | | | | | | - 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77019 91177308-0d34-0410-b5e6-96231b3b80d8
