Bill Wendling 4d5275905e Implement a special algorithm for converting uint_to_fp for i32 values on
X86. This code:

void f() {
  uint32_t x;
  float y = (float)x;
}

used to be:

     movl     %eax, -8(%ebp)
     movl     [2^52 double], -4(%ebp)
     movsd    -8(%ebp), %xmm0
     subsd    [2^52 double], %xmm0
     cvtsd2ss %xmm0, %xmm0

Is now:

   movsd        [2^52 double], %xmm0
   movsd        %xmm0, %xmm1
   movd         %ecx, %xmm2
   orps         %xmm2, %xmm1
   subsd        %xmm0, %xmm1
   cvtsd2ss     %xmm1, %xmm0

This is faster on X86. Note that there's an extra load of %xmm0 into %xmm1. That
will be fixed in a later coalescer fix.

Dan Gohman 5f8a2598b2 Instead of adding dependence edges between terminator instructions
and every other instruction in their blocks to keep the terminator
instructions at the end, teach the post-RA scheduler how to operate
on ranges of instructions, and exclude terminators from the range
of instructions that get scheduled.

Also, exclude mid-block labels, such as EH_LABEL instructions, and
schedule code before them separately from code after them. This
fixes problems with the post-RA scheduler moving code past
EH_LABELs.

Dan Gohman 157e008816 If an anti-dependence uses a non-allocatable register, set AntiDepReg
to 0, to ensure that the subsequent code doesn't try to break the
dependence.

Dan Gohman 38978ba972 Use the getNode() accessor instead of accessing the Node
member directly, which is private as of r55504.

Dan Gohman f1002495e3 Disable the post-RA scheduler on this test, since it uses a
simple %prcontext which doesn't find what it's looking for
if the scheduler has rearranged the instructions.

2009-01-16 21:40:12 +00:00
Dan Gohman 014142fd1a Fix the check for an empty basic block to check for an empty SUnits
array instead, since this is what the scheduler actually cares about.
And remove a check that is unnecessary, since it can assume that
SUnits isn't empty.

Evan Cheng 968e2e7b3d CreateVirtualRegisters does trivial copy coalescing. If a node def is used by a single CopyToReg, it reuses the virtual register assigned to the CopyToReg. This won't work for SDNode that is a clone or is itself cloned. Disable this optimization for those nodes or it can end up with non-SSA machine instructions.

Evan Cheng 5f936ef1ac Change isGVCompilationDisabled() semantics again. It should abort on any GV that's not constant whether it's "internal" or not. In a server / client environment, GV is returned in the same block of memory as code. However, the memory might not be writable.

Sanjiv Gupta 30bd194504 Few targets do not have a single directive to emit global constants.
For example, PIC16 needs to break a long or int constant into mulitple parts and emit multiple directives. So Allow targets to overried EmitConstantValueOnly().

Evan Cheng beac6f8b0c Clean up previous cast optimization a bit. Also make zext elimination a bit more aggressive: if it's not necessary to emit an AND (i.e. high bits are already zero), it's profitable to evaluate the operand at a different type.
