[PATCH] D44814: [CodeGenPrepare] Split huge basic blocks for faster compilation.

[escha via Phabricator via llvm-commits]

escha added a comment.

this does not feel like the right solution, but even if it is, this will hurt us; we *commonly* have shaders with single basic blocks exceeding 1000 instructions, and splitting them could sabotage scheduling quite badly. in the worst case, it could guarantee spilling, by splitting the block at a point that creates too many live values between the top and bottom.
