This patch would like to refactor the helper function of the SAT_*
scalar. The helper function will convert the define_pattern ops
to the xmode reg for the underlying code-gen. This patch add
new parameter for ZERO_EXTEND or SIGN_EXTEND if the input is const_int
or the mode is non-Xmode.
The below test suites are passed for this patch.
* The rv64gcv fully regression test.
gcc/ChangeLog:
* config/riscv/riscv.cc (riscv_gen_zero_extend_rtx): Rename from ...
(riscv_extend_to_xmode_reg): Rename to and add rtx_code for
zero/sign extend if non-Xmode.
(riscv_expand_usadd): Leverage the renamed function with ZERO_EXTEND.
(riscv_expand_ussub): Ditto.
And just to be 100% clear, the other patches in this series are fine
once this one has gone onto the trunk.
