Fix to bug 1951: tblgen gratuitously renames variables when no temporary was
...
generated. This feature would only show up in fairly complex patterns, such
as this one in CellSPU:
def : Pat<(add (SPUhi tconstpool:$in, 0), (SPUlo tconstpool:$in, 0)),
(IOHLlo (ILHUhi tconstpool:$in), tconstpool:$in)>;
which generated the following emit code:
SDNode *Emit_0(const SDOperand &N, unsigned Opc0, unsigned Opc1, MVT::ValueType VT0, MVT::ValueType VT1) DISABLE_INLINE {
SDOperand N0 = N.getOperand(0);
SDOperand N00 = N0.getOperand(0);
SDOperand N01 = N0.getOperand(1);
SDOperand N1 = N.getOperand(1);
SDOperand N10 = N1.getOperand(0);
SDOperand N11 = N1.getOperand(1);
SDOperand Tmp3(CurDAG->getTargetNode(Opc0, VT0, N00), 0);
return CurDAG->SelectNodeTo(N.Val, Opc1, VT1, Tmp3, Tmp2); /* Tmp2 s/b N00 */
}
Tested against the test suites without incident.

Overhaul Cell SPU's addressing mode internals so that there are now
...
only two addressing mode nodes, SPUaform and SPUindirect (vice the
three previous ones, SPUaform, SPUdform and SPUxform). This improves
code somewhat because we now avoid using reg+reg addressing when
it can be avoided. It also simplifies the address selection logic,
which was the main point for doing this.
Also, for various global variables that would be loaded using SPU's
A-form addressing, prefer D-form offs[reg] addressing, keeping the
base in a register if the variable is used more than once.

Implement some dag combines that allow doing fneg/fabs/fcopysign in integer
...
registers if used by a bitconvert or using a bitconvert. This allows us to
avoid constant pool loads and use cheaper integer instructions when the
values come from or end up in integer regs anyway. For example, we now
compile CodeGen/X86/fp-in-intregs.ll to:
_test1:
movl $2147483648, %eax
xorl 4(%esp), %eax
ret
_test2:
movl $1065353216, %eax
orl 4(%esp), %eax
andl $3212836864, %eax
ret
Instead of:
_test1:
movss 4(%esp), %xmm0
xorps LCPI2_0, %xmm0
movd %xmm0, %eax
ret
_test2:
movss 4(%esp), %xmm0
andps LCPI3_0, %xmm0
movss LCPI3_1, %xmm1
andps LCPI3_2, %xmm1
orps %xmm0, %xmm1
movd %xmm1, %eax
ret
bitconverts can happen due to various calling conventions that require
fp values to passed in integer regs in some cases, e.g. when returning
a complex.
