So GCC has always accepted non-pointer types in computed gotos but
that was wrong based on the documentation:
Any expression of type void * is allowed.
So this fixes the problem by requiring the type to
be a pointer type.
OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions.
PR c/32122
gcc/c/ChangeLog:
* c-parser.c (c_parser_statement_after_labels): Pass
the c_expr instead of the tree to c_finish_goto_ptr.
* c-typeck.c (c_finish_goto_ptr): Change the second
argument type to c_expr.
* c-tree.h (c_finish_goto_ptr): Likewise.
Error out if the expression was not of a pointer type.
gcc/testsuite/ChangeLog:
* gcc.dg/comp-goto-5.c: New test.
* gcc.dg/comp-goto-6.c: New test.
OK
