commit r17-2509-g15fd8d8b5b5b4abf181d7440ac1e05119e936fb9 Author: Pan Li <[email protected]> Date: Sat Jul 18 11:23:16 2026 +0800 RISC-V: Split the pr112431-13 test in to 2 file The vfwcvt_x_f_v and vfwcvt_rtz_x_f_v are placed in one file, and when allow overlap for vfwcvt_x_f_v. The csrr scan still xfail. Therefore, split it into two files to make sure both the vfwcvt_x_f_v and vfwcvt_rtz_x_f_v has no csrr after enable overlap. gcc/testsuite/ChangeLog: * gcc.target/riscv/rvv/base/pr112431-13.c: Move to... * gcc.target/riscv/rvv/base/pr112431-13-0.c: ...here. * gcc.target/riscv/rvv/base/pr112431-13-1.c: New test.
