* 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
