Nate Begeman 006bb04f3a Support multiple ValueTypes per RegisterClass, needed for upcoming vector 
work.  This change has no effect on generated code.

Evan Cheng 4b02426130 Proper support for shifts with register shift value.

Evan Cheng d94aa71e1a Use a getCopyToReg() variant to generate a flaggy CopyToReg node. 
llvm-svn: 24558
 2005-12-01 00:41:50 +00:00
Evan Cheng fed83adbe3 Teach tblgen to accept register source operands in patterns, e.g. 
def SHL8rCL  : I<0xD2, MRM4r, (ops R8 :$dst, R8 :$src),
                 "shl{b} {%cl, $dst|$dst, %CL}",
                 [(set R8:$dst, (shl R8:$src, CL))]>, Imp<[CL],[]>;

This generates a CopyToReg operand and added its 2nd result to the shl as
a flag operand.

Nate Begeman faad542d24 Nuke CodeGenInstruction's ValueType member, it is no longer used. 
llvm-svn: 24556
 2005-12-01 00:12:04 +00:00
Nate Begeman cdf2c67888 Stop checking the ValueType of the CodeGenInstruction. Instead, use the 
ValueType from the RegisterClass or Operands.  This step is necessary to
allow RegisterClasses to have multiple ValueTypes.

Nate Begeman 6f8c1ace6e No longer track value types for asm printer operands, and remove them as 
an argument to every operand printing function.  Requires some slight
tweaks to x86, the only user.

Andrew Lenharth 873ed82a36 FPSelect and more custom lowering 
llvm-svn: 24535
 2005-11-30 16:10:29 +00:00
Nate Begeman 1064d6ec43 First chunk of actually generating vector code for packed types. These 
changes allow us to generate the following code:

_foo:
        li r2, 0
        lvx v0, r2, r3
        vaddfp v0, v0, v0
        stvx v0, r2, r3
        blr

for this llvm:

void %foo(<4 x float>* %a) {
entry:
        %tmp1 = load <4 x float>* %a
        %tmp2 = add <4 x float> %tmp1, %tmp1
        store <4 x float> %tmp2, <4 x float>* %a
        ret void
}

Andrew Lenharth 6db615df14 All sorts of stuff. 
Getting in on the custom lowering thing, yay
evilness with fp setcc, yuck
trivial int select, hmmm
in memory args for functions, yay
DIV and REM, always handy.  They should be custom lowered though.

Lots more stuff compiles now (go go single source!).  Of course, none of it
probably works, but that is what the nightly tester can find out :)

Reid Spencer 3fd1b4c9bf Fix a problem with llvm-ranlib that (on some platforms) caused the archive 
file to become corrupted due to interactions between mmap'd memory segments
and file descriptors closing. The problem is completely avoiding by using
a third temporary file.

Nate Begeman 048b26387b Represent the encoding of the SPR instructions as they actually are, so

Nate Begeman c138118cdb Add the remainder of the AltiVec 4 x float instructions. Further 
enhancements will be necessary to teach the code generator that since
there is no fmul, it will have to do vmaddfp, adding +0.0.
