Sanjoy Das f73780ec1a [RewriteStatepointsForGC] Strip deref info after rewriting. ... Summary: Once a gc.statepoint has been rewritten to relocate live references, the SSA values represent physical pointers instead of logical references. Logical dereferencability does not imply physical dereferencability and after RewriteStatepointsForGC has run any attributes that imply dereferencability of the logical references need to be stripped. This current approach is conservative, and can be made more precise later if needed. For starters, we need to strip dereferencable attributes only from pointers that live in the GC address space.

basics.ll	[RewriteStatepointsForGC] For some values (like gep's and bitcasts) it's cheaper to clone them after statepoint than to emit proper relocates for them. This change implements this logic. There is alredy similar optimization in CodeGenPrepare, but doing so during RewriteStatepointsForGC allows to capture more opprtunities such as relocates in loops and longer instruction chains.	2015-05-19 15:59:05 +00:00
