Subject: Remove expanding complex EQ/NE inside a GIMPLE_RETURN [PR115721]
X-Git-Tag: basepoints/gcc-16~7620

Remove expanding complex EQ/NE inside a GIMPLE_RETURN [PR115721]

This code has been dead at least since the move over to tuples
in 0-88576-g726a989a8b74bf, when gimple returns could only have
a simple expression in it. So let's remove it.

Bootstrapped and tested on x86_64-linux-gnu with no regressions.

gcc/ChangeLog:

	PR tree-optimization/115721
	* tree-complex.cc (expand_complex_comparison): Remove
	support for GIMPLE_RETURN.
