Jim Laskey e220821deb Groups were not emitted if the dominator node and the node in the ordering list 
were not the same node.  Ultimately the test was bogus.

Nate Begeman 53c1f75090 Since extload can also be used by FP, split STDIntExtLoad into two parts, 
one for use with extload, one for use with sextload and zextload, which
are integer only.

Chris Lattner 5580e69df6 Add constant pool support, including folding into addresses. 
Pretty print addresses a bit, to not print [%r1+%g0]: just print [%r1]

Chris Lattner 726075fdf8 Teach the addressing mode stuff to fold "%lo" into 'ri' addressing modes, 
allowing us to compile this:

to this:

%G1 = external global int
%G2 = external global int
void %test() {
        %X = load int* %G1
        store int %X, int* %G2
        ret void
}

test:
        save -96, %sp, %sp
        sethi %hi(G1), %l0
        ld [%l0+%lo(G1)], %l0
        sethi %hi(G2), %l1
        st %l0, [%l1+%lo(G2)]
        restore %g0, %g0, %g0
        retl
        nop

instead of this:

test:
        save -96, %sp, %sp
        sethi %hi(G1), %l0
        or %g0, %lo(G1), %l1
        ld [%l1+%l0], %l0
        sethi %hi(G2), %l1
        or %g0, %lo(G2), %l2
        st %l0, [%l2+%l1]
        restore %g0, %g0, %g0
        retl
        nop

Chris Lattner a49b652a62 Claiming that branch targets are registers is not very wholesome. Change them 
to be basic blocks.  Also, add uncond branches.

Chris Lattner e39ab718c0 add andn/orn/xorn patterns. This allows us to compile this: 
long %test(ubyte, short, long %X, long %Y) {
  %A = xor long %X, -1
  %B = and long %Y, %A
  ret long %B
}

to this:

test:
        save -96, %sp, %sp
        andn %i4, %i2, %i0
        andn %i5, %i3, %i1
        restore %g0, %g0, %g0
        retl
        nop

instead of this:

test:
        save -96, %sp, %sp
        xor %i2, -1, %l0
        xor %i3, -1, %l1
        and %i4, %l0, %i0
        and %i5, %l1, %i1
        restore %g0, %g0, %g0
        retl
        nop

The simpleisel emits:  :(

test:
        save -96, %sp, %sp
        or %g0, -1, %l0
        or %g0, -1, %l0
        or %g0, -1, %l0
        or %g0, -1, %l1
        xor %i2, %l0, %l0
        xor %i3, %l1, %l1
        and %i4, %l0, %i0
        and %i5, %l1, %i1
        restore %g0, %g0, %g0
        retl

Evan Cheng 1d71248392 Darwin API issue: indirect load of external and weak symbols. 
llvm-svn: 24775
 2005-12-17 09:13:43 +00:00
Chris Lattner 866cef563b Add some simple integer patterns. This allows us to compile this: 
int %test(int %A) {
  %B = add int %A, 1
  %C = xor int %B, 123
  ret int %C
}

into this:

test:
        save -96, %sp, %sp
        add %i0, 1, %l0
        xor %l0, 123, %i0
        restore %g0, %g0, %g0
        retl
        nop

for example.  I guess it would make sense to add reg/reg versions too.
