This patch provides optimization of bit manipulation operations by enabling the +experimental-b target feature. It adds matching of single block patterns of instructions to specific bit-manip instructions from the single-bit subset (zbs subextension) of the experimental B extension of RISC-V. It adds also the correspondent codegen tests. This patch is based on Claire Wolf's proposal for the bit manipulation extension of RISCV: https://github.com/riscv/riscv-bitmanip/blob/master/bitmanip-0.92.pdf Differential Revision: https://reviews.llvm.org/D79874 |
