Hello there. I am trying to track down a problem with gcc 4.1 which has to do with inlining and templates on PowerPC. Is there any documentation I can look related to the output generated with -fdump? I am getting extraneous lwz (load word and zero extend) instructions inserted when calling various methods - after $toc (r2) has been switched to the destination method's global data, just before the method call with the bctrl instruction. This lwz instruction causes a crash on IBM AIX when 32-bit shared libraries are loaded non-contiguously in memory. It looks like various code blocks are not being combined correctly when code is inlined - the extra lwz is being left behind.
I have figured out that turning off gcse optimizations will stop this behavior, but doing this causes a performance hit. I would prefer not to upgrade the compiler at this time. With the compiler dump using -fdump, I am looking for a better way to work around this problem. Tim Crook.
