Dan Gohman 906716c40f Fix a compile error on compilers that still want a return value 
in a non-void function that calls abort.

Chris Lattner 5287765d1a Add a new SparsePropagation analysis utility, which allows you to do 
SCCP like sparse lattice analysis with relative ease.  Just pick your
lattice function and implement the transfer function and you're good.
Just make sure you don't break monotonicity ;-)

Nick Lewycky c38c1712f7 Make constructors target-specific. This fixes problems where the path would

Chris Lattner 47fed61526 Fix various DOUTs to not call the extremely expensive Value::getName() 
method.  DOUT statements are disabled when assertions are off, but the
side effects of getName() are still evaluated.  Just call getNameSTart,
which is close enough and doesn't cause heap traffic.

Dan Gohman 3c0e11af64 For now, abort when an ISD::VAARG is encountered on x86-64, rather 
than silently generate invalid code.

llvm-gcc does not currently use VAArgInst; it lowers va_arg in the
front-end.

llvm-svn: 50861
 2008-05-08 17:46:35 +00:00
Chris Lattner 49a594e6ab More than just loads can read from memory: readonly calls like strlen 
also need to be checked for memory modifying instructions before we
can sink them.  THis fixes the second half of PR2297.

llvm-svn: 50860
 2008-05-08 17:37:37 +00:00
Chris Lattner 4fa09669d8 Make instcombine's DSE respect loads as well as stores. It is not safe to 
delete the first store in:

store x -> p
load p

This is for PR2297.

llvm-svn: 50859
 2008-05-08 17:20:30 +00:00

Duncan Sands 9897eee483 Get exception handling working again on 64 bit 
Darwin.  This is a hack of course, but it does
at least look at the right thing: gotpcrel means
that this is already an offset, so an explicit
offset is not needed (and wrong).  I think this
is good enough for the moment: Anton is working
on something better.

llvm-svn: 50850
 2008-05-08 12:33:11 +00:00

llvm-svn: 50828
 2008-05-07 20:04:18 +00:00
Chris Lattner 621d33bbc0 Add a new LibCallAliasAnalysis pass, which is parameterized 
by an instance of LibCallInfo to provide mod/ref info of
standard library functions.  This is powerful enough to
say that 'sqrt' is readonly except that it modifies errno,
or that "printf doesn't store to memory unless the %n
constraint is present" etc.

llvm-svn: 50827
 2008-05-07 19:53:05 +00:00
Ted Kremenek 7b66ad294b Fix some serious logical errors in CStrInCStrNoCase pointed out by Bill.

 2008-05-07 19:22:36 +00:00
Duncan Sands e2b0bf43a7 Output correct exception handling and frame info 
on x86-64 linux.  This causes no regressions on
32 bit linux and 32 bit ppc.  More tests pass
on 64 bit ppc with no regressions.  I didn't
turn on eh on 64 bit linux because the intrinsics
needed to compile the eh runtime aren't done
yet.  But if you turn it on and link with the
mainline runtime then eh seems to work fine
on x86-64 linux with this patch.  Thanks to
Dale for testing.  The main point of the patch
is that if you output that some object is
encoded using 4 bytes you had better not output
8 bytes for it: the patch makes everything
consistent.

llvm-svn: 50825
 2008-05-07 19:11:09 +00:00

 2008-05-07 18:35:46 +00:00
Chris Lattner 9a35f1b702 Add a new interface for describing the behavior of library calls. This 
Currently is sufficient to describe mod/ref behavior but will hopefully
eventually be extended for other purposes.

This isn't used by anything yet.

llvm-svn: 50820

Nick Lewycky 5fcecbffca Typo. 
llvm-svn: 50805
 2008-05-07 06:39:04 +00:00
Evan Cheng 7ca4a67ca1 Yet another nasty spiller bug. 
%ecx = op
store %cl<kill>, (addr)
(addr) = op %al

It's not safe to unfold the last operand and eliminate store even though %cl is marked kill. It's a sub-register use which means one of its super-register(s) may be used below.
