The following testcase ICEs on i686-linux, because c_finish_return wraps c_fully_folded retval back into EXCESS_PRECISION_EXPR, but when the function return type is void, we don't call convert_for_assignment on it that would then be fully folded again, but just put the retval into RETURN_EXPR's operand, so nothing removes it anymore and during gimplification we ICE as EXCESS_PRECISION_EXPR is not handled. This patch fixes it by not adding that EXCESS_PRECISION_EXPR in functions returning void, the return value is ignored and all we need is evaluate any side-effects of the expression. 2021-02-18 Jakub Jelinek <jakub@redhat.com> PR c/99136 * c-typeck.c (c_finish_return): Don't wrap retval into EXCESS_PRECISION_EXPR in functions that return void. * gcc.dg/pr99136.c: New test.
