7ab65934a0 The X86 instruction selector already handles codegen of:
store float 123.45, float* %P

18ad19488d Allow the selection-dag based selector to be diabled with -disable-pattern-isel.

To enable the new selector, pass -disable-pattern-isel=false to llc or lli.

cfa0f2edd3 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.

6e7ba45460 This is a bulk commit that implements the following primary improvements:
* We can now fold cast instructions into select instructions that
    have at least one constant operand.
  * We now optimize expressions more aggressively based on bits that are
    known to be zero.  These optimizations occur a lot in code that uses
    bitfields even in simple ways.
  * We now turn more cast-cast sequences into AND instructions.  Before we
    would only do this if it if all types were unsigned.  Now only the
    middle type needs to be unsigned (guaranteeing a zero extend).
  * We transform sign extensions into zero extensions in several cases.

This corresponds to these test/Regression/Transforms/InstCombine testcases:
  2004-11-22-Missed-and-fold.ll
  and.ll: test28-29
  cast.ll: test21-24

6dec0b09d5 Fix a FIXME: Select instructions on longs were miscompiled.
While we're at it, improve codegen of select instructions.  For this
testcase:

int %test(bool %C, int %A, int %B) {
  %D = select bool %C, int %A, int %B
  ret int %D
}

We used to generate this code:

_test:
        cmpwi cr0, r3, 0
        bne .LBB_test_2 ;
.LBB_test_1:    ;
        b .LBB_test_3   ;
.LBB_test_2:    ;
        or r5, r4, r4
.LBB_test_3:    ;
        or r3, r5, r5
        blr

Now we emit:

_test:
        cmpwi cr0, r3, 0
        bne .LBB_test_2 ;
.LBB_test_1:    ;
        or r4, r5, r5
.LBB_test_2:    ;
        or r3, r4, r4
        blr

e7f96c515e Substantially improve the code generated by non-folded setcc instructions.
In particular, instead of compiling this:

bool %test(int %A, int %B) {
  %C = setlt int %A, %B
  ret bool %C
}

to this:

test:
        save %sp, -96, %sp
        subcc %i0, %i1, %g0
        bl .LBBtest_1   !
        nop
        ba .LBBtest_2   !
        nop
.LBBtest_1:     !
        or %g0, 1, %i0
        ba .LBBtest_3   !
        nop
.LBBtest_2:     !
        or %g0, 0, %i0
        ba .LBBtest_3   !
        nop
.LBBtest_3:     !
        restore %g0, %g0, %g0
        retl
        nop

We now compile it to this:

test:
        save %sp, -96, %sp
        subcc %i0, %i1, %g0
        or %g0, 1, %i0
        bl .LBBtest_2   !
        nop
.LBBtest_1:     !
        or %g0, %g0, %i0
.LBBtest_2:     !
        restore %g0, %g0, %g0
        retl
        nop

aeb47b8db9 Fix a bug that made the nightly tester *really* slow. During changes for
portability, the --track-space option was inadvertently ignored. This patch
fixes that so that sys::Process::GetMallocUsage() is only invoked if the
--track-spaces option is given. Apparently the mallinfo() call that
GetMallocUsage() uses is *very* slow, especially when processing very large
modules like projects/llvm-test/MultiSource/Applications/kimwitu++.

c0354c904b Set the rounding mode for the X86 FPU to 64-bits instead of 80-bits. We
don't support long double anyway, and this gives us FP results closer to
other targets.

This also speeds up 179.art from 41.4s to 18.32s, by eliminating a problem
with extra precision that causes an FP == comparison to fail (leading to
extra loop iterations).

f731be0dd5 Finally enable the setcc-branch folding code.
Also, fix a bug where ubyte 255 would sometimes be output as -1. This
was afflicting hbd.

077f1a8292 Though the previous xform applies to literally dozens (hundreds?) of variables
in SPEC, the subsequent optimziations that we are after don't play with
with FP values, so disable this xform for them.  Really we just don't want
stuff like:

double G;   (always 0 or 412312.312)
  = G;

turning into:

bool G_b;
  = G_b ? 412312.312 : 0;

We'd rather just do the load.

96a86b2993 If a variable can only hold two values, and is not already a bool, shrink it
down to actually BE a bool.  This allows simple value range propagation
stuff work harder, deleting comparisons in bzip2 in some hot loops.

This implements GlobalOpt/integer-bool.ll, which is the essence of the
loop condition distilled into a testcase.

a177c67471 If one side of and/or is known to be 0/-1, it doesn't matter
if the other side is overdefined.

This allows us to fold conditions like:  if (X < Y || Y > Z) in some cases.

dade2d22ba Two bug fixes:
1. Actually increment the Statistic for the GV elim optzn
 2. When resolving undef branches, only resolve branches in executable blocks,
    avoiding marking a bunch of completely dead blocks live.  This has a big
    impact on the quality of the generated code.

With this patch, we positively rip up vortex, compiling Ut_MoveBytes to a
single memcpy call. In vortex we get this:

     12 ipsccp           - Number of globals found to be constant
    986 ipsccp           - Number of arguments constant propagated
   1378 ipsccp           - Number of basic blocks unreachable
   8919 ipsccp           - Number of instructions removed

56c5d7369b Bools are *also* not ints. Sigh. Furthermore, most of the TargetMachine
ctor parameters can be defaulted.

Print the transformed llvm code input to the instruction selector
when -print-machineinstrs is on, just like V9.

4658ba13a8 Look for many more moves to fold (previously, we only
*or g0, x      add g0, x          recognized * as a move)
 or  x, g0     add  x, g0
 or  0, x      add  0, x
 or  x, 0      add  x, 0

4f70b63ebc Make GEPs not suck so much:
* Don't emit the Index * ElementSize multiply if Index is a constant.
* Use a shift, not a multiply, if ElementSize is 1/2/4/8.
* If ElementSize fits in the immediate field of SMUL, then put it there.

Fix a bug where struct offsets might be truncated (ConstantSInt::get is
now used instead of ConstantInt::get).
