From: Pan Li <pan2...@intel.com>
This patch would like to fix one ICE when vector is not enabled
in hook TARGET_FUNCTION_VALUE_REGNO_P implementation. The vector
regno is available if and only if the TARGET_VECTOR is true. The
previous implement missed this condition and then result in ICE
when rv64gc build option without vector.
PR target/114639
The below test suite is passed for this patch.
* The rv64gcv fully regression tests.
* The rv64gc fully regression tests.
gcc/ChangeLog:
* config/riscv/riscv.cc (riscv_function_value_regno_p): Add
TARGET_VECTOR predicate for V_RETURN regno.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/pr114639-1.c: New test.
* gcc.target/riscv/pr114639-2.c: New test.
* gcc.target/riscv/pr114639-3.c: New test.
* gcc.target/riscv/pr114639-4.c: New test.
