and APFloat::convertToInteger.  Restore return value to
IEEE754.  Adjust all users accordingly.

Duncan Sands 32052e8272 Use template to distinguish between function variants. 
GCC 4.4.0 gives an error on the "int" declaration for example
saying that it has already been declared (using the "short"
one). Using templates here allow the compiler to distinguish
between the function to choose.

Also, "llvm/Support/DataTypes.h" was not included, leading to
error messages about not knowing "uint32_t" for example.

Patch by Samuel Tardieu.

Dan Gohman 60ad173dfe Remove -disable-fast-isel. Use cl::boolOrDefault with -fast-isel 
instead.

So now: -fast-isel or -fast-isel=true enable fast-isel, and
-fast-isel=false disables it. Fast-isel is also on by default
with -fast, and off by default otherwise.

Dan Gohman b3ba449cfb Add MBB successors and physreg Uses in the same order that 
SDISel typically adds them in. This makes it a little easier
to compare FastISel output with SDISel output.

Dan Gohman c1d47c56f9 Avoid emitting redundant materializations of integer constants 
for things like null pointers, which at this level aren't
different from regular integer constants.

 2008-10-07 22:03:27 +00:00
Dan Gohman d3917157d5 Instead of emitting an implicit use for the super-register of 
X86::CL that was used, emit an EXTRACT_SUBREG from the CL
super-register to CL. This more precisely describes how the
CL register is being used.

Dale Johannesen 7221af384d Mark negative-zero-to-int conversion as Inexact, 
since -0.0 can't be represented as an int.
This prevents llvm from reducing -0.0 to a
load-and-convert of int 0.  Fixes
ieee.exp/mzero[2356].c in gcc testsuite.

Dale Johannesen 6c6729f3a8 Be more precise about which conversions of NaNs 
are Inexact.  (These are not Inexact as defined
by IEEE754, but that seems like a reasonable way
to abstract what happens:  information is lost.)
