llvm-svn: 33619
 2007-01-29 17:51:02 +00:00
Reid Spencer d7035b654b Use TargetData to obtain the correct size of the "size_t" argument for 
functions like memcpy, memmove and memset. Ensure only one prototype is
used for these functions and that it matches the system definition by
using the appropriate type for the size argument.

Nick Lewycky 56639800c9 Simplify names of lattice values. SGTUNE becomes SGT, for example. 
Fix initializeConstant, now initializeInt. Fixes major performance
bottleneck.

X == Y || X->DominatedBy(Y) is redundant. Remove the X == Y part.

Fix crasher in makeEqual where getOrInsertNode would add a new constant,
producing an NE relationship between the two members we're trying to make
equal. This now allows us to mark more BBs as unreachable.

llvm-svn: 33610
 2007-01-29 00:21:34 +00:00
Reid Spencer c7765617d2 For PR1138: 
Force memcpy to be the 32-bit variant. Since this is only used with
CBE and lli which both target 32-bit machines, this should be okay.

Anton Korobeynikov 06f7d4bec7 Arguments are counting from 1. not from 0. Maybe we should change

Anton Korobeynikov 75e8a144d4 Regenerate 
llvm-svn: 33599
 2007-01-28 13:37:39 +00:00
Anton Korobeynikov 037c867b54 Propagate changes from my local tree. This patch includes: 
1. New parameter attribute called 'inreg'. It has meaning "place this
parameter in registers, if possible". This is some generalization of
gcc's regparm(n) attribute. It's currently used only in X86-32 backend.
2. Completely rewritten CC handling/lowering code inside X86 backend.
Merged stdcall + c CCs and fastcall + fast CC.
3. Dropped CSRET CC. We cannot add struct return variant for each
target-specific CC (e.g. stdcall + csretcc and so on).
4. Instead of CSRET CC introduced 'sret' parameter attribute. Setting in
on first attribute has meaning 'This is hidden pointer to structure
return. Handle it gently'.
5. Fixed small bug in llvm-extract + add new feature to
FunctionExtraction pass, which relinks all internal-linkaged callees
from deleted function to external linkage. This will allow further
linking everything together.

NOTEs: 1. Documentation will be updated soon.
       2. llvm-upgrade should be improved to translate csret => sret.
          Before this, there will be some unexpected test fails.

We only want to do this if the src and destination types have the same

making a special case for integer types and avoiding the transform if
they don't match.

Chris Lattner 479a9fc492 Fix a regression in my isIntegral patch that broke 471.omnetpp. This is 
because TargetData::getTypeSize() returns the same for i1 and i8.  This fix
is not right for the full generality of bitwise types, but it fixes the
regression.

Nick Lewycky 6ce36cff3a Don't print address of ETNode. Print the DFSNumIn which uniquely identifies 
the basic block and is stable across runs in gdb or valgrind.

Make Node::update handle edges which dominate and are tighter than
existing edges.

Replace makeEqual's "squeeze theorem" code. Fixes miscompilation.

Gate the calls to defToOps and opsToDef. Before this, we were getting IG
edges about values which weren't even defined in the dominated area. This
reduces the size of the IG by about half.

llvm-svn: 33228
 2007-01-15 06:25:39 +00:00
Chris Lattner 03c4953cdd rename Type::isIntegral to Type::isInteger, eliminating the old Type::isInteger. 
rename Type::getIntegralTypeMask to Type::getIntegerTypeMask.

This makes naming much more consistent.  For example, there are now no longer any
instances of IntegerType that are not considered isInteger! :)
