2005-10-19This is a generic test for all code generators. It originally came fromJohn Criswell
Regression/Codegen/X86. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23826 91177308-0d34-0410-b5e6-96231b3b80d8

2005-10-19add support for literal immediates in patterns to match, allowing us toChris Lattner
write things like this: def : Pat<(add GPRC:$in, 12), (ADD12 GPRC:$in)>; Andrew: if this isn't enough or doesn't work for you, please lemme know. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23819 91177308-0d34-0410-b5e6-96231b3b80d8

2005-10-19Nate wants to define 'Pat's which turn into instructions that don't haveChris Lattner

the pair of elements is a legal type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23804 91177308-0d34-0410-b5e6-96231b3b80d8
2005-10-19Make a new reg class for 64 bit regs that aliases the 32 bit regs. ThisNate Begeman
will have to tide us over until we get real subreg support, but it prevents the PrologEpilogInserter from spilling 8 byte GPRs on a G4 processor. Add some initial support for TRUNCATE and ANY_EXTEND, but they don't currently work due to issues with ScheduleDAG. Something wll have to be figured out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23803 91177308-0d34-0410-b5e6-96231b3b80d8
2005-10-18Add the ability to lower return instructions to TargetLowering. ThisNate Begeman
allows us to lower legal return types to something else, to meet ABI requirements (such as that i64 be returned in two i32 regs on Darwin/ppc). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23802 91177308-0d34-0410-b5e6-96231b3b80d8

2005-10-18Add an option to this pass. If it is set, we are allowed to internalizeChris Lattner
all but main. If it's not set, we can still internalize, but only if an explicit symbol list is provided. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23783 91177308-0d34-0410-b5e6-96231b3b80d8

2005-10-18Fold (select C, load A, load B) -> load (select C, A, B). This happens quiteChris Lattner
a lot throughout many programs. In particular, specfp triggers it a bunch for constant FP nodes when you have code like cond ? 1.0 : -1.0. If the PPC ISel exposed the loads implicit in pic references to external globals, we would be able to eliminate a load in cases like this as well: %X = external global int %Y = external global int int* %test4(bool %C) { %G = select bool %C, int* %X, int* %Y ret int* %G } Note that this breaks things that use SrcValue's (see the fixme), but since nothing uses them yet, this is ok. Also, simplify some code to use hasOneUse() on an SDOperand instead of hasNUsesOfValue directly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23781 91177308-0d34-0410-b5e6-96231b3b80d8

2005-10-18Do the right thing and enable 64 bit regs under the control of a subtargetNate Begeman
option. Currently the only way to enable this is to specify the 64bitregs mattr flag. It is never enabled by default on any config yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23779 91177308-0d34-0410-b5e6-96231b3b80d8
