X-Git-Tag: basepoints/gcc-15~6277
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b90a4c3dd502974f352084c23a6cdfd767e1340b;p=thirdparty%2Fgcc.git

RISC-V: Elimilate warning in class vcreate

The following is the content of class vcreate:
class vcreate : public function_base
{
public:
  gimple *fold (gimple_folder &f) const override
  {
    ....
  }

  rtx expand (function_expander &e) const override
  {
    return NULL_RTX;
  }
};

The warning caused is:
./riscv-gcc/gcc/config/riscv/riscv-vector-builtins-bases.cc:1719:34:
  warning: unused parameter 'e' [-Wunused-parameter]
  rtx expand (function_expander &e) const override
                                 ^

gcc/ChangeLog:

	* config/riscv/riscv-vector-builtins-bases.cc: remove unused
		parameter e and replace NULL_RTX with gcc_unreachable.
