Duncan P. N. Exon Smith ec8c491a06 SDAG: Give SDDbgValues their own allocator (and reset it) Previously `SDDbgValue`s used the general allocator that lives for all of `SelectionDAG`. Instead, give them their own allocator, and reset it whenever `SDDbgInfo::clear()` is called, plugging a spiritual leak. This drops `SelectionDAGBuilder::visitIntrinsicCall()` off of my heap profile (was at around 2% of `llc` for codegen of `-flto -g`). Thanks to Pete Cooper for spotting the problem and suggesting the fix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@237998 91177308-0d34-0410-b5e6-96231b3b80d8	2015-05-22 05:45:19 +00:00

Previously `SDDbgValue`s used the general allocator that lives for all
of `SelectionDAG`.  Instead, give them their own allocator, and reset it
whenever `SDDbgInfo::clear()` is called, plugging a spiritual leak.

This drops `SelectionDAGBuilder::visitIntrinsicCall()` off of my heap
profile (was at around 2% of `llc` for codegen of `-flto -g`).  Thanks
to Pete Cooper for spotting the problem and suggesting the fix.
