* rename getPPCOpcodeForSetCCNumber -> getPPCOpcodeForSetCCOpode to be moreChris Lattner2005-04-101-21/+21
| | | | | | | | | correct. Remove the EmitComparison retvalue, as it is always the first arg. Fix a place where we incorrectly passed in the setcc opcode instead of the setcc number, causing us to miscompile crafty. Crafty now works! llvm-svn: 21195
* fix ISD::BRCONDTWOWAY codegen to not deference the end() iteratorNate Begeman2005-04-091-1/+1
| | | | llvm-svn: 21193
* Fix CodeGen/Generic/2005-05-09-GlobalInPHI.ll, which was reduced from 254.gap.Chris Lattner2005-04-091-0/+16
| | | | | | | | This caused the "use before a def" assertion on some programs. With this patch, 254.gap now passes with the PPC backend. llvm-svn: 21191
* add a little peephole optimization. This allows us to codegen:Chris Lattner2005-04-091-0/+11
| | | | | | | | | | | | | | | | | | | | | | | int a(short i) { return i & 1; } as _a: andi. r3, r3, 1 blr instead of: _a: rlwinm r2, r3, 0, 16, 31 andi. r3, r2, 1 blr on ppc. It should also help the other risc targets. llvm-svn: 21189
* do not set the root to null if an argument is deadChris Lattner2005-04-091-1/+2
| | | | llvm-svn: 21188
* Add rlwnm instruction for variable rotateNate Begeman2005-04-092-29/+79
| | | | | | | | Generate rotate left/right immediate Generate code for brcondtwoway Use new livein/liveout functionality llvm-svn: 21187
* Fix a crash on 173.applu by asking for a constant bigger than 32-bits.Chris Lattner2005-04-091-1/+1

* Switch this instruction selector over to using liveins and liveouts, eliminatingChris Lattner2005-04-091-8/+26
| | | | | | implicit defs on entry to the function. yaay :) llvm-svn: 21184
* there is no need to remove this instruction, linscan does it already as itChris Lattner2005-04-091-5/+0
| | | | | | removes noop moves. llvm-svn: 21183
* Adjust live intervals to support a livein setChris Lattner2005-04-091-2/+44
| | | | llvm-svn: 21182
* Use live out sets for return values instead of imp_defs, which is cleaner ↵Chris Lattner2005-04-092-14/+41
| | | | | | and faster. llvm-svn: 21181
* Consider the livein/out set for a function, allowing targets to not have toChris Lattner2005-04-091-0/+20
| | | | | | use ugly imp_def/imp_uses for arguments and return values. llvm-svn: 21180
* ok, the "ia64 has a boatload of registers" joke stopped being funny today ;)Duraid Madina2005-04-091-1/+6
| | | | | | | | | | * fix overallocation of integer (stacked) registers: we can't allocate registers for local use if they are required as output registers this fixes 'toast' in the test suite, and all sorts of larger programs like bzip2 etc. llvm-svn: 21178
* Optimize FSEL a bit for fneg arguments. This fixes the recently added testNate Begeman2005-04-091-11/+12
| | | | | | | | | | | | | | | | | | | | case so that we emit _test_fneg_sel: .LBB_test_fneg_sel_0: ; fsel f1, f1, f3, f2 blr instead of: _test_fneg_sel: .LBB_test_fneg_sel_0: ; fneg f0, f1 fneg f0, f0 fsel f1, f0, f3, f2 blr llvm-svn: 21177
* Fix CodeGen/SparcV9/2005-05-09-GEP-Crash.ll a crash on some specfp programChris Lattner2005-04-091-1/+1
| | | | | | lets hope this doesn't break other programs with induced entropy llvm-svn: 21174
* recognize some patterns as fabs operations, so that fabs at the source levelChris Lattner2005-04-091-0/+21
| | | | | | | | | | | | | is deconstructed then reconstructed here. This catches 19 fabs's in 177.mesa 9 in 168.wupwise, 5 in 171.swim, 3 in 172.mgrid, and 14 in 173.applu out of specfp2000. This allows the X86 code generator to make MUCH better code than before for each of these and saves one instr on ppc. This depends on the previous CFE patch to expose these correctly. llvm-svn: 21171

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | this into sign/zero extension instructions later. On PPC, for example, this testcase: %G = external global sbyte implementation void %test(int %X, int %Y) { %C = setlt int %X, %Y %D = cast bool %C to sbyte store sbyte %D, sbyte* %G ret void } Now codegens to: cmpw cr0, r3, r4 li r3, 1 li r4, 0 blt .LBB_test_2 ; .LBB_test_1: ; or r3, r4, r4 .LBB_test_2: ; addis r2, r2, ha16(L_G$non_lazy_ptr-"L00000$pb") lwz r2, lo16(L_G$non_lazy_ptr-"L00000$pb")(r2) stb r3, 0(r2) instead of: cmpw cr0, r3, r4 li r3, 1 li r4, 0 blt .LBB_test_2 ; .LBB_test_1: ; or r3, r4, r4 .LBB_test_2: ; *** rlwinm r3, r3, 0, 31, 31 addis r2, r2, ha16(L_G$non_lazy_ptr-"L00000$pb") lwz r2, lo16(L_G$non_lazy_ptr-"L00000$pb")(r2) stb r3, 0(r2) llvm-svn: 21148

* This patch does two things. First, it canonicalizes 'X >= C' -> 'X > C-1'Chris Lattner2005-04-071-7/+49
| | | | | | | | | | | | | | | | | | | | (likewise for <= >=u >=u). Second, it implements a special case hack to turn 'X gtu SINTMAX' -> 'X lt 0' On powerpc, for example, this changes this: lis r2, 32767 ori r2, r2, 65535 cmplw cr0, r3, r2 bgt .LBB_test_2 into: cmpwi cr0, r3, 0 blt .LBB_test_2 llvm-svn: 21142
