Craig Topper	81efb82570	[RISCV] Teach RISCVMatInt about cases where it can use LUI+SLLI to replace LUI+ADDI+SLLI for large constants. ... If we need to shift left anyway we might be able to take advantage of LUI implicitly shifting its immediate left by 12 to cover part of the shift. This allows us to use more bits of the LUI immediate to avoid an ADDI. isDesirableToCommuteWithShift now considers compressed instruction opportunities when deciding if commuting should be allowed. I believe this is the same or similar to one of the optimizations from D79492. Reviewed By: luismarques, arcbbb Differential Revision: https://reviews.llvm.org/D105417	2021-07-20 09:22:06 -07:00
