[PATCH 1/3] RISC-V: Improve codegen for negative repeating large constants

Improve handling of constants where its upper and lower 32-bit halves are the same and have negative values. e.g. for: unsigned long f (void) { return 0xf0f0f0f0f0f0f0f0UL; } Without the patch: li a0,-252645376 addia0,a0,240 li a5,-252645376 addia5,a5,241 sllia5,a5,32 add
