Yes, it's supposed to call cexp(complex(0,x)), but now looking at the code
there
seems to be a typo:
narg = fold_build2 (COMPLEX_EXPR, ctype,
build_real (type, dconst0), arg);
/* Make sure not to fold the cexp call again. */
call = build1 (ADDR_EXPR, build_pointer_type (TREE_TYPE (fn)), fn);
return expand_expr (build_call_nary (ctype, call, 1, arg),
target, VOIDmode, 0);
it builds the call with 'arg' instead of 'narg'. Argh. This bug was
introduced
by the CALL_EXPR changes:
narg = fold_build2 (COMPLEX_EXPR, ctype,
build_real (type, dconst0), arg);
/* Make sure not to fold the cexp call again. */
call = build1 (ADDR_EXPR, build_pointer_type (TREE_TYPE (fn)), fn);
- return expand_expr (build3 (CALL_EXPR, ctype, call,
- build_tree_list (NULL_TREE, narg),
- NULL_TREE), target, VOIDmode, 0);
+ return expand_expr (build_call_nary (ctype, call, 1, arg),
+ target, VOIDmode, 0);
I'll fix it in a second.
