 2008-03-14 21:17:54 +00:00
Evan Cheng 84aec09fdb Fix PR2138. Apparently any modification to a std::multimap (including remove entries for a different key) can invalidate multimap iterators.

Dale Johannesen 0dfd3f33f7 Implement the real calling convention for ppc32 Altivec: 
vectors go at the end of the memory area, after all
non-vector parameters.

Duncan Sands a06e4f3050 Simplify using getIntPtrConstant. 
llvm-svn: 48355
 2008-03-14 05:23:57 +00:00
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

Evan Cheng db443ca377 Livein copy scheduling fixes: do not coalesce physical register copies, correctly determine the safe location to insert the copies.

Owen Anderson 7a69e3aef3 Fix a bug in GVN that Duncan noticed, where we potentially need to insert a 
pointer bitcast when performing return slot optimization.

Evan Cheng 8f8a8b28e9 Don't try to sink 3-address instruction if convertToThreeAddress created more than one instructions.

Evan Cheng ecde45ecb5 A test case I forgot to check in.

llvm-svn: 48334
 2008-03-13 06:38:28 +00:00
Evan Cheng 5c26bde55e TwoAddressInstructionPass enhancement. After it converts a two address instruction into a 3-address one, sink it past the instruction that kills the read-mod-write register if its definition is used past the kill. This reduces the number of live register by one.

Christopher Lamb dd55d3f1b2 Get rid of a pseudo instruction and replace it with subreg based operation on real instructions, ridding the asm printers of the hack used to do this previously. In the process, update LowerSubregs to be careful about eliminating copies that have side affects. 
Note: the coalescer will have to be careful about this too, when it starts coalescing insert_subreg nodes.

Evan Cheng 0ceb8eb150 Improve VarInfo::removeKill() by using std::find instead of linear search. 
llvm-svn: 48321
 2008-03-13 02:42:55 +00:00
Nick Lewycky 7698bfbe16 Update -mem2reg to use succ_iterator instead of iterating across TerminatorInst 
successors. This makes it support nounwind.

Dan Gohman 1412f515c3 Don't redundantly clear std::vector members in destructors. 
llvm-svn: 48316
 2008-03-13 01:57:34 +00:00
Dan Gohman 73caf5ff10 Change PMTopLevelManager's PassManagers vector element type from 
Pass* to PMDataManager*. PMDataManager is more specific than Pass,
so this more accurately describes the objects that are being stored.

This eliminates the need for several dynamic_casts to PMDataManager*.
It does introduce one dynamic_cast though, in dumpPasses(). Give
this one a comment describing why a dynamic_cast is being used.

llvm-svn: 48315
 2008-03-13 01:48:32 +00:00
Dan Gohman 11eecd635c Change PMStack::push to accept a PMDataManager* instead of 
a Pass*. PMDataManager* is what it actually holds, so this
makes it clearer.
