------- Comment #4 from jakub at gcc dot gnu dot org 2009-09-03 11:58 ------- Created an attachment (id=18472) --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=18472&action=view) gcc45-pr41238.patch
Here is an untested fix (well, tested on the provided testcase, but nothing else). The function.c change is only needed for arguments passed by invisible reference which don't have the pointers passed in registers, but on the stack (say long double argument on alpha or sparc -m32 with -mlong-double-128 which has 6 or so other integral arguments before it). Saying the stack slot contains the parameter is certainly wrong in that case. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41238
