2005-04-10* store immediate values as int64_t, not int. come on, we should be happyDuraid Madina
when there are immediates, let's not worry about the memory overhead of this :) * add addU64Imm(uint64_t val) to machineinstrbuilder (seriously: this seems required to support 64-bit immediates cleanly. if it _really_ gets on your nerves, feel free to pull it out ;) ) coming up next week: "all your floating point constants are belong to us" git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21208 91177308-0d34-0410-b5e6-96231b3b80d8

2005-04-10Until we have a dag combiner, promote using zextload's instead of extloads.Chris Lattner
This gives the optimizer a bit of information about the top-part of the value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21205 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21198 91177308-0d34-0410-b5e6-96231b3b80d8

2005-04-10Fix a thinko. If the operand is promoted, pass the promoted value intoChris Lattner
the new zero extend, not the original operand. This fixes cast bool -> long on ppc. Add an unrelated fixme git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21196 91177308-0d34-0410-b5e6-96231b3b80d8
2005-04-10rename getPPCOpcodeForSetCCNumber -> getPPCOpcodeForSetCCOpode to be moreChris Lattner
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! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21195 91177308-0d34-0410-b5e6-96231b3b80d8

2005-04-09Fix CodeGen/Generic/2005-05-09-GlobalInPHI.ll, which was reduced from 254.gap.Chris Lattner
This caused the "use before a def" assertion on some programs. With this patch, 254.gap now passes with the PPC backend. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21191 91177308-0d34-0410-b5e6-96231b3b80d8
2005-04-09new testcase that used to crash the ppc fe. It could effect any simpleiselChris Lattner
that is not careful, so I'm checking it into the generic tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21190 91177308-0d34-0410-b5e6-96231b3b80d8
2005-04-09add a little peephole optimization. This allows us to codegen:Chris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21189 91177308-0d34-0410-b5e6-96231b3b80d8

2005-04-09Switch this instruction selector over to using liveins and liveouts, eliminatingChris Lattner
implicit defs on entry to the function. yaay :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21184 91177308-0d34-0410-b5e6-96231b3b80d8

removes noop moves. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21183 91177308-0d34-0410-b5e6-96231b3b80d8

2005-04-09Use live out sets for return values instead of imp_defs, which is cleaner ↵Chris Lattner
and faster. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21181 91177308-0d34-0410-b5e6-96231b3b80d8

2005-04-09ok, the "ia64 has a boatload of registers" joke stopped being funny today ;)Duraid Madina
* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21178 91177308-0d34-0410-b5e6-96231b3b80d8
2005-04-09Optimize FSEL a bit for fneg arguments. This fixes the recently added testNate Begeman
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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21177 91177308-0d34-0410-b5e6-96231b3b80d8
2005-04-09Add a testcase to make sure that we don't emit two fneg instructions backNate Begeman
to back for certain fsel instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21176 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21173 91177308-0d34-0410-b5e6-96231b3b80d8
2005-04-09recognize some patterns as fabs operations, so that fabs at the source levelChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21171 91177308-0d34-0410-b5e6-96231b3b80d8
