[PATCH] D109037: [RISCV] Enable shrink wrap by default

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

GCC's shrink wrapping is more sophisticated than LLVM's. LLVM's has very little tuning and doesn't support wrapping in more than one basic blocks. With this, future optimization will ... need to adjust the RISC-V tests but that's probably fine.
