This commit introduces a comprehensive set of new test cases for the RISC-V Vector extension, focusing on the vfwcvt.f.x.v instruction. These tests specifically explore register group overlap across various data types (i8, i16, i32) and vector lengths (m1, m2, m4, mf2, mf4, mf8). The goal is to validate the compiler’s handling of these overlap conditions for signed integer to floating-point conversions.
