2005-04-12Implement bitfield clearsNate Begeman
Implement divide by negative power of two git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21240 91177308-0d34-0410-b5e6-96231b3b80d8
2005-04-11Update PPC readme. Remove things that are done or aren't ppc specificNate Begeman

2005-04-11Teach the dag mechanism that this:Chris Lattner
long long test2(unsigned A, unsigned B) { return ((unsigned long long)A << 32) + B; } is equivalent to this: long long test1(unsigned A, unsigned B) { return ((unsigned long long)A << 32) | B; } Now they are both codegen'd to this on ppc: _test2: blr or this on x86: test2: movl 4(%esp), %edx movl 8(%esp), %eax ret git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21231 91177308-0d34-0410-b5e6-96231b3b80d8
2005-04-11Fix expansion of shifts by exactly NVT bits on arch's (like X86) that haveChris Lattner
masking shifts. This fixes the miscompilation of this: long long test1(unsigned A, unsigned B) { return ((unsigned long long)A << 32) | B; } into this: test1: movl 4(%esp), %edx movl %edx, %eax orl 8(%esp), %eax ret allowing us to generate this instead: test1: movl 4(%esp), %edx movl 8(%esp), %eax ret git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21230 91177308-0d34-0410-b5e6-96231b3b80d8

2005-04-11Revert the previous patch, which I didn't mean to check in.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21226 91177308-0d34-0410-b5e6-96231b3b80d8
2005-04-11Fix a minor bug (ORo didn't mark that it set CR0).Chris Lattner
Refactor how . instructions are handled. In particular, instead of passing the RC flag all the way up the inheritance hierarchy, just make a new tblgen class 'DOT' which can be added to an instruction definition. For example, instead of this: -def AND : XForm_6<31, 28, 0, 0, 0, (ops GPRC:$rA, GPRC:$rS, GPRC:$rB), -let Defs = [CR0] in -def ANDo : XForm_6<31, 28, 1, 0, 0, (ops GPRC:$rA, GPRC:$rS, GPRC:$rB), - "and. $rA, $rS, $rB">; We now have this: +def AND : XForm_6<31, 28, 0, 0, (ops GPRC:$rA, GPRC:$rS, GPRC:$rB), "and $rA, $rS, $rB">; git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21225 91177308-0d34-0410-b5e6-96231b3b80d8
2005-04-11hmm, should probably change addImm() to take 64-bit arguments one day anyway.Duraid Madina
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21224 91177308-0d34-0410-b5e6-96231b3b80d8

2005-04-11Add recording variants of ISD::AND and ISD::OR. This kills almost 1000Nate Begeman
(1.5%) instructions in 186.crafty git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21222 91177308-0d34-0410-b5e6-96231b3b80d8
2005-04-11assorted fixes:Duraid Madina
* clean up immediates (we use 14, 22 and 64 bit immediates now. sane.) * fold r0/f0/f1 registers into comparisons against 0/0.0/1.0 * fix nasty thinko - didn't use two-address form of conditional add for extending bools to integers, so occasionally there would be garbage in the result. it's amazing how often zeros are just sitting around in registers ;) - this should fix a bunch of tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21221 91177308-0d34-0410-b5e6-96231b3b80d8
2005-04-11Ensure that the arguments passed to sys::Program::ExecuteAndWait includeReid Spencer
the program name as the first argument. Thanks go to Markus Oberhumer for noticing this problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21220 91177308-0d34-0410-b5e6-96231b3b80d8

2005-04-11Fix libcall code to not pass a NULL Chain to LowerCallToNate Begeman
Fix libcall code to not crash or assert looking for an ADJCALLSTACKUP node when it is known that there is no ADJCALLSTACKDOWN to match. Expand i64 multiply when ISD::MULHU is legal for the target. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21214 91177308-0d34-0410-b5e6-96231b3b80d8
2005-04-10Don't bother sign/zext_inreg'ing the result of an and operation if we knowChris Lattner
the result does change as a result of the extend. This improves codegen for Alpha on this testcase: int %a(ushort* %i) { %tmp.1 = load ushort* %i %tmp.2 = cast ushort %tmp.1 to int %tmp.4 = and int %tmp.2, 1 ret int %tmp.4 } Generating: a: ldgp $29, 0($27) ldwu $0,0($16) and $0,1,$0 ret $31,($26),1 instead of: a: ldgp $29, 0($27) ldwu $0,0($16) and $0,1,$0 addl $0,0,$0 ret $31,($26),1 btw, alpha really should switch to livein/outs for args :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21213 91177308-0d34-0410-b5e6-96231b3b80d8

2005-04-10The first argument to ExecuteAndWait should be the program name, but pointedChris Lattner
out by Markus F.X.J. Oberhumer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21211 91177308-0d34-0410-b5e6-96231b3b80d8

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

have to inform the register allocator it might be stepped on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21202 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

2005-04-09add 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
