Chris Lattner 53ccb62712 implement an initial hack at a straight-line store -> memset optimization. 
This fires dozens of times across spec and multisource, but I don't know
if it actually speeds stuff up.  Hopefully the testers will show something
nice :)

Dan Gohman 9988569af8 Don't include <map> in Pass.h, which doesn't need it. This requires 
adding <map> to many files that actually do need it.

Dan Gohman 026eed69e7 Avoid calling array_endof in a static initializer, as it incurs 
dynamic initialization.

Dan Gohman 5a6ac79738 Specialize FORCE_DEFINING_FILE_TO_BE_LINKED using a GCC trick 
to avoid using constructor calls for static objects. This reduces
the number of objects requiring static constructors in a typical
LLVM build by around 20%.

Duncan Sands dec270a6db Make it possible to get an empty struct using 
the new StructType::get method.  The second NULL
is to pacify the gcc warning mechanism.  This
patch compiles but is otherwise untested.

Duncan Sands d97eea372a Introduce a new node for holding call argument 
flags.  This is needed by the new legalize types
infrastructure which wants to expand the 64 bit
constants previously used to hold the flags on
32 bit machines.  There are two functional changes:
(1) in LowerArguments, if a parameter has the zext
attribute set then that is marked in the flags;
before it was being ignored; (2) PPC had some bogus
code for handling two word arguments when using the
ELF 32 ABI, which was hard to convert because of
the bogusness.  As suggested by the original author
(Nicolas Geoffray), I've disabled it for the moment.
Tested with "make check" and the Ada ACATS testsuite.

Chris Lattner 68b11e14bc remove Evan's "ugly hack" that sorta attempted to get 
x86-64 return conventions correct, but was never enabled.
We can now do the "right thing" with multiple return values.

llvm-svn: 48635
 2008-03-21 06:50:21 +00:00
Chris Lattner 5abbe6cef5 Add support for calls that return two FP values in 
ST(0)/ST(1).

Chris Lattner 7e59a30e9f disable a bogus assertion. 
llvm-svn: 48633
 2008-03-21 06:01:05 +00:00
Chris Lattner b6f04a3e0a Enable support for returning two long-double values in ST(0)/ST(1). 
This allows us to compile fp-stack-2results.ll into:

_test:
	fldz
	fld1
	ret

which returns 1 in ST(0) and 0 in ST(1).  This is needed for x86-64
_Complex long double.

Chris Lattner c44160ce6e Teach masked value is zero about add and sub, and use MVIZ to 
simplify things like (X & 4) >> 1 == 2  --> (X & 4) == 4.

since it is obvious that the shift doesn't remove any bits.
