Evan Cheng 9add880566 Initial support for register pressure aware scheduling. The register reduction
scheduler can go into a "vertical mode" (i.e. traversing up the two-address
chain, etc.) when the register pressure is low.
This does seem to reduce the number of spills in the cases I've looked at. But
with x86, it's no guarantee the performance of the code improves.
It can be turned on with -sched-vertically option.

Loading and storing off R0 isn't what we wanted.  Also, taking some CR's out of
CRRC seems to cause failures as well.  Further investigation is required.

Chris Lattner b8065a9a3a Several related changes:
1. Change several methods in the MachineCodeEmitter class to be pure virtual.
2. Suck emitConstantPool/initJumpTableInfo into startFunction, removing them
   from the MachineCodeEmitter interface, and reducing the amount of target-
   specific code.
3. Change the JITEmitter so that it allocates constantpools and jump tables
   *right* next to the functions that they belong to, instead of in a separate
   pool of memory.  This makes all memory for a function be contiguous, and
   means the JITEmitter only tracks one block of memory now.

Chris Lattner e1c96369e2 Fix a purely hypothetical problem (for now): emitWord emits in the host
byte format.  This doesn't work when using the code emitter in a cross target
environment.  Since the code emitter is only really used by the JIT, this
isn't a current problem, but if we ever start emitting .o files, it would be.

2006-05-02 19:14:47 +00:00
Chris Lattner c9aa3715e8 Refactor the machine code emitter interface to pull the pointers for the current
code emission location into the base class, instead of being in the derived classes.

This change means that low-level methods like emitByte/emitWord now are no longer
virtual (yaay for speed), and we now have a framework to support growable code
segments.  This implements feature request #1 of PR469.

Chris Lattner fd0a5478a1 Fix a latent bug that my spiller patch last week exposed: we were leaving
instructions in the virtregfolded map that were deleted.  Because they
were deleted, newly allocated instructions could end up at the same address,
magically finding themselves in the map.  The solution is to remove entries
from the map when we delete the instructions.

Evan Cheng 24e795496d Bottom up register-pressure reduction scheduler now pushes store operations
up the schedule. This helps code that looks like this:

loads ...
computations (first set) ...
stores (first set) ...
loads
computations (seccond set) ...
stores (seccond set) ...

Without this change, the stores and computations are more likely to
interleave:

loads ...
loads ...
computations (first set) ...
computations (second set) ...
computations (first set) ...
stores (first set) ...
computations (second set) ...

Chris Lattner 84e95d00b5 When we have a two-address instruction where the input cannot be clobbered
and is already available, instead of falling back to emitting a load, fall
back to emitting a reg-reg copy.  This generates significantly better code
for some SSE testcases, as SSE has lots of two-address instructions and
none of them are read/modify/write.  As one example, this change does:

        pshufd %XMM5, XMMWORD PTR [%ESP + 84], 255
        xorps %XMM2, %XMM5
        cmpltps %XMM1, %XMM0
-       movaps XMMWORD PTR [%ESP + 52], %XMM0
-       movapd %XMM6, XMMWORD PTR [%ESP + 52]
+       movaps %XMM6, %XMM0
        cmpltps %XMM6, XMMWORD PTR [%ESP + 68]
        movapd XMMWORD PTR [%ESP + 52], %XMM6
        movaps %XMM6, %XMM0
        cmpltps %XMM6, XMMWORD PTR [%ESP + 36]
        cmpltps %XMM3, %XMM0
-       movaps XMMWORD PTR [%ESP + 20], %XMM0
-       movapd %XMM7, XMMWORD PTR [%ESP + 20]
+       movaps %XMM7, %XMM0
        cmpltps %XMM7, XMMWORD PTR [%ESP + 4]
        movapd XMMWORD PTR [%ESP + 20], %XMM7
        cmpltps %XMM4, %XMM0

... which is far better than a store followed by a load!

Evan Cheng 14215c36b6 Revamp build_vector lowering to take advantage of movss and movd instructions.
movd always clear the top 96 bits and movss does so when it's loading the
value from memory.
The net result is codegen for 4-wide shuffles is much improved. It is near
optimal if one or more elements is a zero. e.g.

__m128i test(int a, int b) {
  return _mm_set_epi32(0, 0, b, a);
}

compiles to

_test:
	movd 8(%esp), %xmm1
	movd 4(%esp), %xmm0
	punpckldq %xmm1, %xmm0
	ret

compare to gcc:

_test:
	subl	$12, %esp
	movd	20(%esp), %xmm0
	movd	16(%esp), %xmm1
	punpckldq	%xmm0, %xmm1
	movq	%xmm1, %xmm0
	movhps	LC0, %xmm0
	addl	$12, %esp
	ret

or icc:

_test:
        movd      4(%esp), %xmm0                                #5.10
        movd      8(%esp), %xmm3                                #5.10
        xorl      %eax, %eax                                    #5.10
        movd      %eax, %xmm1                                   #5.10
        punpckldq %xmm1, %xmm0                                  #5.10
        movd      %eax, %xmm2                                   #5.10
        punpckldq %xmm2, %xmm3                                  #5.10
        punpckldq %xmm3, %xmm0                                  #5.10
        ret                                                     #5.10

There are still room for improvement, for example the FP variant of the above example:

__m128 test(float a, float b) {
  return _mm_set_ps(0.0, 0.0, b, a);
}

_test:
	movss 8(%esp), %xmm1
	movss 4(%esp), %xmm0
	unpcklps %xmm1, %xmm0
	xorps %xmm1, %xmm1
	movlhps %xmm1, %xmm0
	ret

The xorps and movlhps are unnecessary. This will require post legalizer optimization to handle.
