2004-04-09Testcase to make sure we can apply the shift to the operands of the select,Chris Lattner
eliminating the shifts git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12801 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-09Implement select.ll:test12*Chris Lattner
This transforms code like this: %C = or %A, %B %D = select %cond, %C, %A into: %C = select %cond, %B, 0 %D = or %A, %C Since B is often a constant, the select can often be eliminated. In any case, this reduces the usage count of A, allowing subsequent optimizations to happen. This xform applies when the operator is any of: add, sub, mul, or, xor, and, shl, shr git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12800 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-09Add testcases for harder combining cases.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12799 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-09Fold code like:Chris Lattner
if (C) V1 |= V2; into: Vx = V1 | V2; V1 = select C, V1, Vx when the expression can be evaluated unconditionally and is *cheap* to execute. This limited form of if conversion is quite handy in lots of cases. For example, it turns this testcase into straight-line code: int in0 ; int in1 ; int in2 ; int in3 ; int in4 ; int in5 ; int in6 ; int in7 ; int in8 ; int in9 ; int in10; int in11; int in12; int in13; int in14; int in15; long output; void mux(void) { output = (in0 ? 0x00000001 : 0) | (in1 ? 0x00000002 : 0) | (in2 ? 0x00000004 : 0) | (in3 ? 0x00000008 : 0) | (in4 ? 0x00000010 : 0) | (in5 ? 0x00000020 : 0) | (in6 ? 0x00000040 : 0) | (in7 ? 0x00000080 : 0) | (in8 ? 0x00000100 : 0) | (in9 ? 0x00000200 : 0) | (in10 ? 0x00000400 : 0) | (in11 ? 0x00000800 : 0) | (in12 ? 0x00001000 : 0) | (in13 ? 0x00002000 : 0) | (in14 ? 0x00004000 : 0) | (in15 ? 0x00008000 : 0) ; } git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12798 91177308-0d34-0410-b5e6-96231b3b80d8

2004-04-09Reversed the order of the llvm.writeport() operands so that the valueJohn Criswell
is listed first and the address is listed second. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12795 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-09Fold binary operators with a constant operand into select instructionsChris Lattner
that have a constant operand. This implements add.ll:test19, shift.ll:test15*, and others that are not tested git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12794 91177308-0d34-0410-b5e6-96231b3b80d8

2004-04-09Modified the prototypes of the llvm.readport and llvm.writeport intrinsicsJohn Criswell
so that they do not specify specific integer sizes (as those are constrained by the code generator, not the intrinsic itself). Also put these intrinsics into their own "Operating System" section. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12789 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12788 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-09Changed assertions to error messages.John Criswell
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12787 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-08Changes recommended by Chris:John Criswell
InstSelectSimple.cpp: Change the checks for proper I/O port address size into an exit() instead of an assertion. Assertions aren't used in Release builds, and handling this error should be graceful (not that this counts as graceful, but it's more graceful). Modified the generation of the IN/OUT instructions to have 0 arguments. X86InstrInfo.td: Added the OpSize attribute to the 16 bit IN and OUT instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12786 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-08Implement InstCombine/cast-propagate.llChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12784 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-08New testcaseChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12783 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-08Added the llvm.readport and llvm.writeport intrinsics for x86. These doJohn Criswell
I/O port instructions on x86. The specific code sequence is tailored to the parameters and return value of the intrinsic call. Added the ability for implicit defintions to be printed in the Instruction Printer. Added the ability for RawFrm instruction to print implict uses and defintions with correct comma output. This required adjustment to some methods so that a leading comma would or would not be printed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12782 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-08Added the llvm.readport and llvm.writeport intrinsics.John Criswell
The Verifier ensures that their parameters are of integral types and have the correct sign, but it does not enforce any size restrictions because such restrictions are platform dependent. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12781 91177308-0d34-0410-b5e6-96231b3b80d8

2004-04-08Disable strict alias analysis in the backend c compiler, as the code weChris Lattner
generate is not TBAA safe. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12774 91177308-0d34-0410-b5e6-96231b3b80d8

2004-04-08Right, we break strict aliasing requirements. Make sure to disable strictChris Lattner
aliasing in the C compiler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12772 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-08Remove the "really gross hacks" that are there to deal with recursive functions.Chris Lattner
Now we collect all of the call sites we are interested in inlining, then inline them. This entirely avoids issues with trying to inline a call site we got by inlining another call site. This also eliminates iterator invalidation issues. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12770 91177308-0d34-0410-b5e6-96231b3b80d8
