This is the final big of factoring. This shares cases in suboperand
...
differences, which means that identical instructions (after stripping off
the first literal string) do not run any different code at all. On the X86,
this turns this code:
switch (MI->getOpcode()) {
case X86::ADC32mi: printOperand(MI, 4, MVT::i32); break;
case X86::ADC32mi8: printOperand(MI, 4, MVT::i8); break;

case X86::SBB32mi8: printOperand(MI, 4, MVT::i8); break;
case X86::SBB32mr: printOperand(MI, 4, MVT::i32); break;
case X86::SHL32mi: printOperand(MI, 4, MVT::i8); break;

case X86::XOR32mi: printOperand(MI, 4, MVT::i32); break;
case X86::XOR32mi8: printOperand(MI, 4, MVT::i8); break;
case X86::XOR32mr: printOperand(MI, 4, MVT::i32); break;
}
into this:
switch (MI->getOpcode()) {
case X86::ADC32mi:
case X86::ADC32mr:
case X86::ADD32mi:
case X86::ADD32mr:
case X86::AND32mi:

case X86::SBB32mi:
case X86::SBB32mr:
case X86::SHLD32mrCL:
case X86::SHRD32mrCL:
case X86::SUB32mi:
case X86::SUB32mr:
case X86::TEST32mi:
case X86::TEST32mr:
case X86::XCHG32mr:
case X86::XOR32mi:
case X86::XOR32mr: printOperand(MI, 4, MVT::i32); break;
case X86::ADC32mi8:

case X86::SUB32mi8:
case X86::TEST8mi:
case X86::XOR32mi8: printOperand(MI, 4, MVT::i8); break;
}
After this, the generated asmwriters look pretty much as though they were
generated by hand. This shrinks the X86 asmwriter.inc files from 55101->39669
and 55429->39551 bytes each, and PPC from 16766->12859 bytes.

Implement *even more* factoring. In particular, if all of the instruction
...
strings starts out with a constant string, we emit the string first, using
a table lookup (instead of a switch statement).
Because this is usually the opcode portion of the asm string, the differences
between the instructions have now been greatly reduced. This allows many
more case statements to be grouped together.
This patch also allows instruction cases to be grouped together when the
instruction patterns are exactly identical (common after the opcode string
has been ripped off), and when the differing operand is a MachineInstr
operand that needs to be formatted.
The end result of this is a mean and lean generated AsmPrinter!

emitting code like this:
case PPC::ADD: O << "add "; printOperand(MI, 0, MVT::i64); O << ", "; prin
tOperand(MI, 1, MVT::i64); O << ", "; printOperand(MI, 2, MVT::i64); O << '\n
'; break;
case PPC::ADDC: O << "addc "; printOperand(MI, 0, MVT::i64); O << ", "; pr
intOperand(MI, 1, MVT::i64); O << ", "; printOperand(MI, 2, MVT::i64); O << '
\n'; break;
case PPC::ADDE: O << "adde "; printOperand(MI, 0, MVT::i64); O << ", "; pr
intOperand(MI, 1, MVT::i64); O << ", "; printOperand(MI, 2, MVT::i64); O << '
\n'; break;
...
Emit code like this:
case PPC::ADD:
case PPC::ADDC:
case PPC::ADDE:
...
switch (MI->getOpcode()) {
case PPC::ADD: O << "add "; break;
case PPC::ADDC: O << "addc "; break;
case PPC::ADDE: O << "adde "; break;
...
}
printOperand(MI, 0, MVT::i64);
O << ", ";
printOperand(MI, 1, MVT::i64);
O << ", ";
printOperand(MI, 2, MVT::i64);
O << "\n";
break;
This shrinks the PPC asm writer from 24785->15205 bytes (even though the new
asmwriter has much more whitespace than the old one), and the X86 printers shrink
quite a bit too. The important implication of this is that GCC no longer hits swap
when building the PPC backend in optimized mode. Thus this fixes PR448.

Seperate asmstring parsing from emission. This allows the code to be simpler
...
and more understandable. It also allows us to do simple things like fold
consequtive literal strings together. For example, instead of emitting this
for the X86 backend:
O << "adc" << "l" << " ";
we now generate this:
O << "adcl ";
*whoa* :)
This shrinks the X86 asmwriters from 62729->58267 and 65176->58644 bytes
for the intel/att asm writers respectively.

6 or more cycles). This also saves code space.
For example, instead of emitting:
rotr:
mov %EAX, DWORD PTR [%ESP + 4]
mov %CL, BYTE PTR [%ESP + 8]
shrd %EAX, %EAX, %CL
ret
rotli:
mov %EAX, DWORD PTR [%ESP + 4]
shrd %EAX, %EAX, 27
ret
Emit:
rotr32:
mov %CL, BYTE PTR [%ESP + 8]
mov %EAX, DWORD PTR [%ESP + 4]
ror %EAX, %CL
ret
rotli32:
mov %EAX, DWORD PTR [%ESP + 4]
ror %EAX, 27
ret
We also emit byte rotate instructions which do not have a sh[lr]d counterpart
at all.

Non-volatile loads can be freely reordered against each other. This fixes
...
X86/reg-pressure.ll again, and allows us to do nice things in other cases.
For example, we now codegen this sort of thing:
int %loadload(int *%X, int* %Y) {
%Z = load int* %Y
%Y = load int* %X ;; load between %Z and store
%Q = add int %Z, 1
store int %Q, int* %Y
ret int %Y
}
Into this:
loadload:
mov %EAX, DWORD PTR [%ESP + 4]
mov %EAX, DWORD PTR [%EAX]
mov %ECX, DWORD PTR [%ESP + 8]
inc DWORD PTR [%ECX]
ret
where we weren't able to form the 'inc [mem]' before. This also lets the
instruction selector emit loads in any order it wants to, which can be good
for register pressure as well.

Implement a target independent optimization to codegen arguments only into
...
the basic block that uses them if possible. This is a big win on X86, as it
lets us fold the argument loads into instructions and reduce register pressure
(by not loading all of the arguments in the entry block).
For this (contrived to show the optimization) testcase:
int %argtest(int %A, int %B) {
%X = sub int 12345, %A
br label %L
L:
%Y = add int %X, %B
ret int %Y
}
we used to produce:
argtest:
mov %ECX, DWORD PTR [%ESP + 4]
mov %EAX, 12345
sub %EAX, %ECX
mov %EDX, DWORD PTR [%ESP + 8]
.LBBargtest_1: # L
add %EAX, %EDX
ret
now we produce:
argtest:
mov %EAX, 12345
sub %EAX, DWORD PTR [%ESP + 4]
.LBBargtest_1: # L
add %EAX, DWORD PTR [%ESP + 8]
ret
This also fixes the FIXME in the code.
BTW, this occurs in real code. 164.gzip shrinks from 8623 to 8608 lines of
.s file. The stack frame in huft_build shrinks from 1644->1628 bytes,
inflate_codes shrinks from 116->108 bytes, and inflate_block from 2620->2612,
due to fewer spills.

Revamp supported ops. Instead of just being supported or not, we now keep
...
track of how to deal with it, and provide the target with a hook that they
can use to legalize arbitrary operations in arbitrary ways.
Implement custom lowering for a couple of ops, implement promotion for select
operations (which x86 needs).

Turn select C, (X+Y), (X-Y) --> (X+(select C, Y, (-Y))). This occurs in
...
the 'sim' program and probably elsewhere. In sim, it comes up for cases
like this:
#define round(x) ((x)>0.0 ? (x)+0.5 : (x)-0.5)
double G;
void T(double X) { G = round(X); }
(it uses the round macro a lot). This changes the LLVM code from:
%tmp.1 = setgt double %X, 0.000000e+00 ; <bool> [#uses=1]
%tmp.4 = add double %X, 5.000000e-01 ; <double> [#uses=1]
%tmp.6 = sub double %X, 5.000000e-01 ; <double> [#uses=1]
%mem_tmp.0 = select bool %tmp.1, double %tmp.4, double %tmp.6
store double %mem_tmp.0, double* %G
to:
%tmp.1 = setgt double %X, 0.000000e+00 ; <bool> [#uses=1]
%mem_tmp.0.p = select bool %tmp.1, double 5.000000e-01, double -5.000000e-01
%mem_tmp.0 = add double %mem_tmp.0.p, %X
store double %mem_tmp.0, double* %G

Implement an optimization for == and != comparisons like this:
...
_Bool test2(int X, int Y) {
return &arr[X][Y] == arr;
}
instead of generating this:
bool %test2(int %X, int %Y) {
%tmp.3.idx = mul int %X, 160 ; <int> [#uses=1]
%tmp.3.idx1 = shl int %Y, ubyte 2 ; <int> [#uses=1]
%tmp.3.offs2 = sub int 0, %tmp.3.idx ; <int> [#uses=1]
%tmp.7 = seteq int %tmp.3.idx1, %tmp.3.offs2 ; <bool> [#uses=1]
ret bool %tmp.7
}
generate this:
bool %test2(int %X, int %Y) {
seteq int %X, 0 ; <bool>:0 [#uses=1]
seteq int %Y, 0 ; <bool>:1 [#uses=1]
%tmp.7 = and bool %0, %1 ; <bool> [#uses=1]
ret bool %tmp.7
}
This idiom occurs in C++ programs when iterating from begin() to end(),
in a vector or array. For example, we now compile this:
void test(int X, int Y) {
for (int *i = arr; i != arr+100; ++i)
foo(*i);
}
to this:
no_exit: ; preds = %entry, %no_exit
...
%exitcond = seteq uint %indvar.next, 100 ; <bool> [#uses=1]
br bool %exitcond, label %return, label %no_exit
instead of this:
no_exit: ; preds = %entry, %no_exit
...
%inc5 = getelementptr [100 x [40 x int]]* %arr, int 0, int 0, int %inc.rec ; <int*> [#uses=1]
%tmp.8 = seteq int* %inc5, getelementptr ([100 x [40 x int]]* %arr, int 0, int 100, int 0) ; <bool> [#uses=1]
%indvar.next = add uint %indvar, 1 ; <uint> [#uses=1]

movsbl 4(%esp), %eax
movl %eax, %edx

Now we generate:

mov %ECX, -32768
add %ECX, DWORD PTR [l4_match_start]
mov DWORD PTR [l4_match_start], %ECX
Now we get:
add DWORD PTR [l4_match_start], -32768
For other values we used to get:
mov %EBP, %EDI ;; because the add destroys the value
add %EBP, DWORD PTR [l4_input_len]
mov DWORD PTR [l4_input_len], %EBP
now we get:
add DWORD PTR [l4_input_len], %EDI
Both of these use less registers than the alternative, are faster and smaller.

passes the -module option on the libtool command line to ensure that the

is intended to be the target of an LLVM -load option. Note that loadable
modules will not have the lib prefix but otherwise look like shared
libraries. This is per the libtool recommendations and prevents these
special shared libraries from being linked in via -l option to the linker.

Take register pressure into account when we have to decide whether to
...
evaluate the LHS or the RHS of an operation first. This causes good things
to happen. For example, instead of compiling a loop to this:
.LBBstrength_result7_1: # loopentry
movl 16(%esp), %edi
movl (%edi), %edi ;;; LOAD
movl (%ecx), %ebx
movl $2, (%eax,%ebx,4)
movl (%edx), %ebx
movl %esi, %ebp
addl $21, %ebp
addl $42, %esi
cmpl $0, %edi ;;; USE
cmovne %esi, %ebp
cmpl %ebp, %ebx
movl %ebp, %esi
jg .LBBstrength_result7_1
We now compile it to this:
.LBBstrength_result7_1: # loopentry
movl %edi, %ebx
addl $42, %ebx
addl $21, %edi
movl (%ecx), %ebp ;; LOAD
cmpl $0, %ebp ;; USE
cmovne %ebx, %edi
movl (%edx), %ebx
movl $2, (%eax,%ebx,4)
movl (%esi), %ebx
cmpl %edi, %ebx
jg .LBBstrength_result7_1
Which reduces register pressure enough (in this case) to avoid spilling in the
loop.
As another example, consider the CodeGen/X86/regpressure.ll testcase. We
used to generate this code for both cases:
regpressure1:
subl $32, %esp
movl %esi, 12(%esp)
movl %edi, 8(%esp)
movl %ebx, 4(%esp)
movl %ebp, (%esp)
movl 36(%esp), %ecx
movl (%ecx), %eax
movl 4(%ecx), %edx
movl %edx, 24(%esp)
movl 8(%ecx), %edx
movl %edx, 16(%esp)
movl 12(%ecx), %edx
movl 16(%ecx), %esi
movl 20(%ecx), %edi
movl 24(%ecx), %ebx
movl %ebx, 28(%esp)
movl 28(%ecx), %ebx
movl 32(%ecx), %ebp
movl %ebp, 20(%esp)
movl 36(%ecx), %ecx
imull 24(%esp), %eax
imull 16(%esp), %eax
imull %edx, %eax
imull %esi, %eax
imull %edi, %eax
imull 28(%esp), %eax
imull %ebx, %eax
imull 20(%esp), %eax
imull %ecx, %eax
movl (%esp), %ebp
movl 4(%esp), %ebx
movl 8(%esp), %edi
movl 12(%esp), %esi
addl $32, %esp
ret
This code is basically trying to do all of the loads first, then execute all
of the multiplies. Because we run out of registers, lots of spill code happens.
We now generate this code for both cases:
regpressure1:
movl 4(%esp), %ecx
movl (%ecx), %eax
movl 4(%ecx), %edx
imull %edx, %eax
movl 8(%ecx), %edx
imull %edx, %eax
movl 12(%ecx), %edx
imull %edx, %eax
movl 16(%ecx), %edx
imull %edx, %eax
movl 20(%ecx), %edx
imull %edx, %eax
movl 24(%ecx), %edx
imull %edx, %eax
movl 28(%ecx), %edx
imull %edx, %eax
movl 32(%ecx), %edx
imull %edx, %eax
movl 36(%ecx), %ecx
imull %ecx, %eax
ret
which is much nicer (when we fold loads into the muls it will be even better).
The old instruction selector used to produce the good code for regpressure1
but not for regpressure2, as it depended on the order of operations in the
LLVM code.

The pattern isel is aggressively codegen'ing all of the loads in these
...
functions together at the start of the basic block, causing massive spillage.
The old isel codegened the loads wherever they happened to land, so it
generated good code for the first case, but bad code for the second.
We really want the pattern isel to generate (the same) good code for both.

Make the 2-address instruction lowering pass smarter in two ways:
...
1. If we are two-addressing a commutable instruction and the LHS is not the
last use of the variable, see if the instruction is the last use of the
RHS. If so, commute the instruction, allowing us to avoid a
register-register copy in many cases for common instructions like ADD, OR,
AND, etc on X86.
2. If #1 doesn't hold, and if this is an instruction that also existing in
3-address form, promote the instruction to a 3-address instruction to
avoid the register-register copy. We can do this for several common
instructions in X86, including ADDrr, INC, DEC, etc.
This patch implements test/Regression/CodeGen/X86/commute-two-addr.ll,
overlap-add.ll, and overlap-shift.ll when I check in the X86 support for it.
