Implement an annoying part of the Darwin/X86 abi: the callee of a struct
...
return argument pops the hidden struct pointer if present, not the caller.
For example, in this testcase:
struct X { int D, E, F, G; };
struct X bar() {
struct X a;
a.D = 0;
a.E = 1;
a.F = 2;
a.G = 3;
return a;
}
void foo(struct X *P) {
*P = bar();
}
We used to emit:
_foo:
subl $28, %esp
movl 32(%esp), %eax
movl %eax, (%esp)
call _bar
addl $28, %esp
ret
_bar:
movl 4(%esp), %eax
movl $0, (%eax)
movl $1, 4(%eax)
movl $2, 8(%eax)
movl $3, 12(%eax)
ret
This is correct on Linux/X86 but not Darwin/X86. With this patch, we now
emit:
_foo:
subl $28, %esp
movl 32(%esp), %eax
movl %eax, (%esp)
call _bar
*** addl $24, %esp
ret
_bar:
movl 4(%esp), %eax
movl $0, (%eax)
movl $1, 4(%eax)
movl $2, 8(%eax)
movl $3, 12(%eax)
*** ret $4
For the record, GCC emits (which is functionally equivalent to our new code):
_bar:
movl 4(%esp), %eax
movl $3, 12(%eax)
movl $2, 8(%eax)
movl $1, 4(%eax)
movl $0, (%eax)
ret $4
_foo:
pushl %esi
subl $40, %esp
movl 48(%esp), %esi
leal 16(%esp), %eax
movl %eax, (%esp)
call _bar
subl $4, %esp
movl 16(%esp), %eax
movl %eax, (%esi)
movl 20(%esp), %eax
movl %eax, 4(%esi)
movl 24(%esp), %eax
movl %eax, 8(%esi)
movl 28(%esp), %eax
movl %eax, 12(%esi)
addl $40, %esp
popl %esi
ret
This fixes SingleSource/Benchmarks/CoyoteBench/fftbench with LLC and the
JIT, and fixes the X86-backend portion of PR729. The CBE still needs to
be updated.

- Use of load's chain result should be redirected to load's chain operand.

If it reads the chain result of the call, then the use, callseq_start,
and call would form a cycle!
- Don't forget handle node replacement!
- There could also be a TokenFactor between the load and the callseq_start.

Fixing truncate. Previously we were emitting truncate from r16 to r8 as
...
movw. That is we promote the destination operand to r16. So
%CH = TRUNC_R16_R8 %BP
is emitted as
movw %bp, %cx.
This is incorrect. If %cl is live, it would be clobbered.
Ideally we want to do the opposite, that is emitted it as
movb ??, %ch
But this is not possible since %bp does not have a r8 sub-register.
We are now defining a new register class R16_ which is a subclass of R16
containing only those 16-bit registers that have r8 sub-registers (i.e.
AX - DX). We isel the truncate to two instructions, a MOV16to16_ to copy the
value to the R16_ class, followed by a TRUNC_R16_R8.
Due to bug 770, the register colaescer is not going to coalesce between R16 and
R16_. That will be fixed later so we can eliminate the MOV16to16_. Right now, it
can only be eliminated if we are lucky that source and destination registers are
the same.

Better implementation of truncate. ISel matches it to a pseudo instruction
...
that gets emitted as movl (for r32 to i16, i8) or a movw (for r16 to i8). And
if the destination gets allocated a subregister of the source operand, then
the instruction will not be emitted at all.

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.

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.

Added X86 SSE2 intrinsics which can be represented as vector_shuffles. This is
...
a temporary workaround for the 2-wide vector_shuffle problem (i.e. its mask
would have type v2i32 which is not legal).

JumpTable support! What this represents is working asm and jit support for

x86 and ppc for 100% dense switch statements when relocations are non-PIC.
This support will be extended and enhanced in the coming days to support
PIC, and less dense forms of jump tables.

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.
