So, either we do something like:
--- gcc/cgraphclones.c.jj 2014-01-03 11:40:46.000000000 +0100
+++ gcc/cgraphclones.c 2014-01-31 14:34:59.734148380 +0100
@@ -390,6 +390,9 @@ build_function_decl_skip_args (tree orig
DECL_BUILT_IN_CLASS (new_decl) = NOT_BUILT_IN;
DECL_FUNCTION_CODE (new_decl) = (enum built_in_function) 0;
}
+ /* The FE might have information and assumptions about the other
+ arguments. */
+ DECL_LANG_SPECIFIC (new_decl) = NULL;
return new_decl;
}
(works on the testcase, otherwise untested), or add some language hook where
the FE will have a chance to adjust it's DECL_LANG_SPECIFIC based on which
arguments are being removed.
