Evan Cheng a7bfbe996e Two peepholes: 
(or (x >> c) | (y << (32 - c))) ==> (shrd x, y, c)
(or (x << c) | (y >> (32 - c))) ==> (shld x, y, c)

Duraid Madina e08a95d3c1 oops, this shouldn't have gotten in

 2006-01-17 03:09:48 +00:00
Evan Cheng 0d5b69f734 SSE does not support i64 SINT_TO_FP (FP stack doesn't either, but we custom 
expand it), so ask legalizer to expand i32 UINT_TO_FP.

 2006-01-17 02:32:49 +00:00
Duraid Madina 266ff6056a use proper (82-bit) spills/fills when spilling FP regs, so that 
divides don't get broken. this fixes obsequi, smg2000, and probably
a bunch of other stuff (tm)

Evan Cheng 561881f30a Added a FIXME comment about why FST is currently flagged to fpGETRESULT. 
llvm-svn: 25381
 2006-01-17 00:37:42 +00:00
Evan Cheng bec9d720b0 Bug fixes: fpGETRESULT should produces a flag result and X86ISD::FST should 
read a flag.

Duraid Madina e995910e64 fixing divides: FP should now be 100%, and integers are fine too 
unless you try to div/mod 0 by anything, in which case you will
get some cute number, and not 0, which is bad.

Chris Lattner e636ba84b5 Silly Sparc is big endian. If we have to load args out of incoming stack slots 
that are smaller than an int, make sure to adjust the frame pointer to take
this into consideration.

 2006-01-16 01:40:00 +00:00
Chris Lattner 9d41ecc95b Make sure that bool,byte and short arguments are the right type when loaded 
from memory.

Chris Lattner e96523474b Don't print a label for the first MBB in a function. 
Compile this:

%_2E_str_8 = external global [75 x sbyte]
implementation   ; Functions:
declare int %printf(sbyte*, ...)
void %test()
        %tmp.101 = call int (sbyte*, ...)* %printf( sbyte* getelementptr ([75 x sbyte]* %_2E_str_8, int 0, int 0) )             ; <int> [#uses=0]
        unreachable
}

to this:

main_endif_2E_8:
        save -96, %o6, %o6
        sethi %hi(_2E_str_8), %l0
        add %l0, %lo(_2E_str_8), %o0
        call printf
        nop

instead of this:

main_endif_2E_8:
        save -96, %o6, %o6
        sethi %hi(_2E_str_8), %l0
        or %g0, %lo(_2E_str_8), %l1   ;; extra instruction
        add %l1, %l0, %o0
        call printf
        nop
