A comprehensive suite of new test cases has been added to the RISC-V testsuite to specifically address register group overlap scenarios for the vwmacc.vx vector instruction. These tests cover various data types (i8, i16, i32) and different vector lengths (m1, m2, m4, mf2, mf4, mf8), ensuring that the compiler correctly handles potential register conflicts or dependencies when generating code for these instructions.
