Chris Lattner 801f47512d Clean up the FFS optimization code, and make it correctly create the appropriate 
unsigned llvm.cttz.* intrinsic, fixing the 2005-05-11-Popcount-ffs-fls regression
last night.

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.

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)

Reid Spencer b4f9a6f110 For PR411: 
This patch is an incremental step towards supporting a flat symbol table.
It de-overloads the intrinsic functions by providing type-specific intrinsics
and arranging for automatically upgrading from the old overloaded name to
the new non-overloaded name. Specifically:
  llvm.isunordered -> llvm.isunordered.f32, llvm.isunordered.f64
  llvm.sqrt -> llvm.sqrt.f32, llvm.sqrt.f64
  llvm.ctpop -> llvm.ctpop.i8, llvm.ctpop.i16, llvm.ctpop.i32, llvm.ctpop.i64
  llvm.ctlz -> llvm.ctlz.i8, llvm.ctlz.i16, llvm.ctlz.i32, llvm.ctlz.i64
  llvm.cttz -> llvm.cttz.i8, llvm.cttz.i16, llvm.cttz.i32, llvm.cttz.i64
New code should not use the overloaded intrinsic names. Warnings will be
emitted if they are used.

Reid Spencer 84c00ea718 For PR411: 
This file makes the helper functions for auto-upgrade of llvm assembly and
bytecode more accessible. This is part of de-overloading of intrinsic
functions to support the flat symbol table (no type planes).

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.

Nate Begeman 2642a35f4c Expand case for 64b Legalize, even though no one should end up using this 
(itanium supports bswap natively, alpha should custom lower it using the
VAX floating point swapload, ha ha).

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.

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
