[PATCH] D126392: [RISCV] Use two ADDIs to do some stack pointer adjustments.

[Craig Topper via Phabricator via llvm-commits]

craig.topper updated this revision to Diff 432101.
craig.topper added a comment.

Instead of dividing in half use a large immediate, either -2048 or (2048-stackalign),
to do a first adjustment. Then a smaller adjustment for the remainder.
