Here's a patch which fixes the bug. It also fixes an unrelated problem I noticed in that section of code, which was that the structure- return code was clobbering cr3 and cr4, which are designated as callee-saved in the ppc abi documentation I have. (I've never seen a compiler actually use those fields, but still.) This involved moving some of the bitfields in the flags word around. With this patch, libffi-3.0.8 passes four of the five tests which were failing on netbsd5/ppc32 (the fifth test failure is an unrelated problem), as well as the odd_struct.c tests I linked to in my last message. -- Wim Lewis <wiml@hhhh.org>, Seattle, WA, USA.
