From: Ian Romanick <ian.d.roman...@intel.com>
brw_reg::type is "enum brw_reg_type type:4". For whatever reason, GCC
is treating this as an int instead of an enum. As a result, it doesn't
detect missing switch cases and it doesn't detect that flow can get out
of the switch.
This silences the warning:
src/intel/compiler/brw_reg.h: In function ‘bool brw_regs_negative_equal(const
brw_reg*, const brw_reg*)’:
src/intel/compiler/brw_reg.h:305:1: warning: control reaches end of non-void
function [-Wreturn-type]
}
