Chris Lattner 03503b5e31 new testcase for x86 backend miscompilation 
llvm-svn: 33883
 2007-02-04 20:15:15 +00:00
Chris Lattner 19083a4671 switch the VRBaseMap in the scheduler from an std::map to a DenseMap. This 
speeds up the isel pass from 2.5570s to 2.4722s on kc++ (3.4%).

llvm-svn: 33879
 2007-02-04 08:47:20 +00:00
Chris Lattner 9af2c86bc8 Introduce new UnarySDNode/BinarySDNode/TernarySDNode nodes, which coallocate 
their operands with the node itself.  This reduces malloc traffic for operand
lists.  This reduces isel time on kc++ from 2.6164 to 2.5570s, about 2.3%.

llvm-svn: 33878
 2007-02-04 08:35:21 +00:00
Chris Lattner 69b02ab54c Add a new SDNode ctor and InitOperands method. This allows the operands for 
an SDNode to be allocated as part of the node itself, instead of being a
separate new[]'d object.  Switch HandleSDNode, LoadSDNode, and StoreSDNode
to use this mechanism.  This saves one heap allocation and free for each node
of this type that is allocated.  This reduces isel time from 2.7638 to 2.6164s
on kc++, which is a 5.6% speedup.

Reid Spencer d9f7298477 For PR1151: 
Make llvm-upgrade valgrind clean. Deleting type instances is a really
nasty thing to do to LLVM. This was a hold-over from the re-write.
This fixes test/Assembler/2007-01-22-UpgradeTypeMapInvalidMemory.ll and
potentially many other bugs.
