2007-04-03Fix a bug I introduced with my patch yesterday which broke Qt (I convertedChris Lattner
some constant exprs to apints). Thanks to Anton for tracking down a small testcase that triggered this! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35633 91177308-0d34-0410-b5e6-96231b3b80d8

2007-04-03Starting implementation of the ELF32 ABI specification of varargs handling.Nicolas Geoffray
LowerVASTART emits the right code if the subtarget is ELF32, the other intrinsics (VAARG, VACOPY and VAEND) are not yet implemented. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35625 91177308-0d34-0410-b5e6-96231b3b80d8
2007-04-03The PPC64 ELF ABI is "intended to use the same structure layout and calling ↵Nicolas Geoffray
convention rules as the 64-bit PowerOpen ABI" (Reference http://www.linux-foundation.org/spec/ELF/ppc64/). Change all ELF tests to ELF32. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35624 91177308-0d34-0410-b5e6-96231b3b80d8
2007-04-03Addition to the previous commit for getCalleeSavedRegClasses:Nicolas Geoffray
"The ELF ABI specifies F1-F8 registers as argument registers for double, not F1-F10. This affects only ELF, not MachO." git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35623 91177308-0d34-0410-b5e6-96231b3b80d8

2007-04-021. Insert custom lowering hooks for ISD::ROTR and ISD::ROTL.Scott Michel
2. Help DAGCombiner recognize zero/sign/any-extended versions of ROTR and ROTL patterns. This was motivated by the X86/rotate.ll testcase, which should now generate code for other platforms (and soon-to-come platforms.) Rewrote code slightly to make it easier to read. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35605 91177308-0d34-0410-b5e6-96231b3b80d8

to be folded into non-store instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35601 91177308-0d34-0410-b5e6-96231b3b80d8
2007-04-02Ugh. Copy coalescer does not update register numbers.Evan Cheng

2007-04-02add support for the 'w' inline asm register class.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35598 91177308-0d34-0410-b5e6-96231b3b80d8
2007-04-021. Make use of APInt operation instead of using ConstantExpr::getXXX.Zhou Sheng
2. Use cheaper APInt methods. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35594 91177308-0d34-0410-b5e6-96231b3b80d8
2007-04-02Use uint32_t for bitwidth instead of unsigned.Zhou Sheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35593 91177308-0d34-0410-b5e6-96231b3b80d8
2007-04-02Pass the type of the store access, not the type of the store, into theChris Lattner
target hook. This allows us to codegen a loop as: LBB1_1: @cond_next mov r2, #0 str r2, [r0, +r3, lsl #2] add r3, r3, #1 cmn r3, #1 bne LBB1_1 @cond_next instead of: LBB1_1: @cond_next mov r2, #0 str r2, [r0], #+4 add r3, r3, #1 cmn r3, #1 bne LBB1_1 @cond_next This looks the same, but has one fewer induction variable (and therefore, one fewer register) live in the loop. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35592 91177308-0d34-0410-b5e6-96231b3b80d8
2007-04-02Fix a bug which caused us to never be able to use signed comparisons forChris Lattner
equality comparisons of a constant. This allows us to codegen the 'sintzero' loop in PR1288 as: LBB1_1: ;cond_next li r4, 0 addi r2, r2, 1 stw r4, 0(r3) addi r3, r3, 4 cmpwi cr0, r2, -1 bne cr0, LBB1_1 ;cond_next instead of: LBB1_1: ;cond_next addi r2, r2, 1 li r4, 0 xoris r5, r2, 65535 stw r4, 0(r3) addi r3, r3, 4 cmplwi cr0, r5, 65535 bne cr0, LBB1_1 ;cond_next This implements CodeGen/PowerPC/compare-simm.ll, and also cuts 74 instructions out of kc++. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35590 91177308-0d34-0410-b5e6-96231b3b80d8

2007-04-02reduce use of std::setChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35576 91177308-0d34-0410-b5e6-96231b3b80d8
2007-04-02Various passes before isel split edges and do other CFG-restructuring changes.Chris Lattner
isel has its own particular features that it wants in the CFG, in order to reduce the number of times a constant is computed, etc. Make sure that we clean up the CFG before doing any other things for isel. Doing so can dramatically reduce the number of split edges and reduce the number of places that constants get computed. For example, this shrinks CodeGen/Generic/phi-immediate-factoring.ll from 44 to 37 instructions on X86, and from 21 to 17 MBB's in the output. This is primarily a code size win, not a performance win. This implements CodeGen/Generic/phi-immediate-factoring.ll and PR1296. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35575 91177308-0d34-0410-b5e6-96231b3b80d8
2007-04-02- Divides the comparisons in two types: comparisons that only use N and ZLauro Ramos Venancio
flags (ARMISD::CMPNZ) and comparisons that use all flags (ARMISD::CMP). - Defines the instructions: TST, TEQ (ARM) and TST (Thumb). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35573 91177308-0d34-0410-b5e6-96231b3b80d8
2007-04-02For PR1297:Reid Spencer
Make sure that the CTPOP result is casted to i32 as the bit counting intrinsics all return i32 now (this affects CTLZ and CTTZ as well). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35567 91177308-0d34-0410-b5e6-96231b3b80d8

2007-04-01For PR1297:Reid Spencer
Adjust for changes in the bit counting intrinsics. They all return i32 now so we have to trunc/zext the DAG node accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35546 91177308-0d34-0410-b5e6-96231b3b80d8
