Owen Anderson c0daf5fe53 A first stab at memory dependence analysis. This is an interface on top of 
alias analysis, adding caching and lazy computation of queries.  This will
be used in planned improvements to memory access optimizations.

Owen Anderson 7d4bbc1c0c Be more aggressive in the heuristic. This mostly exposes more opportunities 
for the GVN part of GVNPRE to apply.

Owen Anderson 3c3dd902ec Achieve what the incorrect test was trying to do by simply requiring that all 
critical edges be split before we begin.

Owen Anderson bcdd7ec4c9 Remove an incorrect check.

Duncan Sands 9d97420473 The exception handling intrinsics return values, 
so must be lowered to a value, not nothing at all.
Subtle point: I made eh_selector return 0 and
eh_typeid_for return 1.  This means that only
cleanups (destructors) will be run as the exception
unwinds [if eh_typeid_for returned 0 then it would
be as if the first catch always matched, and the
corresponding handler would be run], which is
probably want you want in the CBE.

files.
bitcode files are the only LLVM format left.

operand numbering.

Dan Gohman bab5355ff4 Add an explicit triple to the big-endian tests so that the assembly 
output format is always consistent with what the greps are looking for.

Duncan Sands c5b1984f57 Indexes into the list of filter ids cannot be output 
directly: they need to be turned into byte offsets
(often the same, but may not be if there are many
type infos).

llvm-svn: 37942
 2007-07-06 12:46:24 +00:00
Duncan Sands 6ddf75174a Test that byte offsets are used to index into the list 
of filter ids, and not simply the id index.  Testing
this requires at least 128 type infos!

Dan Gohman d258e80583 Add a parameter to getCopyToParts and getCopyFromParts to specify whether 
endian swapping should be done, and update the code to use it. This fixes
some register ordering issues on big-endian systems, such as PowerPC,
introduced by the recent illegal by-val arguments changes.
