[PATCH] D130784: [AMDGPU] Support LDS spilling

[Jon Chesterfield via Phabricator via llvm-commits]

JonChesterfield added a comment.

I thought we spilled registers to the stack and promoted some stack memory to LDS. Is there any interaction with promoteAlloca? In particular that pass tries to use LDS up to some occupancy boundary, after which allocating more here should take us over that boundary
