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 :)

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.

 2008-03-21 15:53:17 +00:00
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 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

	ret

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

Evan Cheng 44c0b4f754 Fix live variables issues: 
1. If part of a register is re-defined, an implicit kill and an implicit def are added to denote read / mod / write. However, this should only be necessary if the register is actually read later. This is a performance issue.
2. If a sub-register is being defined, and it doesn't have a previous use, do not add a implicit kill to the last use of a super-register:
   = EAX, AX<imp-use,kill>
...
AX =
In this case, EAX is live but AX is killed, this is wrong and will cause the coalescer to do bad things.

the error message.

Christopher Lamb d3d0ad3f58 Make insert_subreg a two-address instruction, vastly simplifying LowerSubregs pass. Add a new TII, subreg_to_reg, which is like insert_subreg except that it takes an immediate implicit value to insert into rather than a register.

Bill Wendling 68a930b33e The inst combining of inttoptr into GEP with one index was using the bit size of 
the type instead of the byte size. This was causing troublesome mis-compilations.

True to form, this took 2 days to find and is a one-line fix. :-P
