Ok, now I have some results from the auto-compile-script-generation.
I got it to work, but it required some manual corrections. First of all, I got link errors, because sched-ebb etc were trying to call various functions, but those functions were not being compiled in because INSN_SCHEDULING was not defined (that's my quick analysis, anyway). So I just grepped those files out of the "source list". Next, a stack of libiberty files were not compiled - strcasecmp, vasprintf, asprintf, getpagesize, strdup. I don't know why this would be the case, because e.g. HAVE_STRCASECMP is not defined. Anyway, I added them to the source list manually, and with a script, awk and m4, I was able to produce my traditional compile script (which is a stepping stone for doing the same thing on MVS). Oh, one other change I made - I normally define PREFIX in a common header file. However, this caused a conflict between prefix.c and regex.c which both try to use this keyword. It would be good if this define was made unique within the source base. I realise there are different ways around this, but it would still be good to be unique. For now I just updated prefix.c to use "" as a default prefix if none is provided. That's neater than any immediate alternative I can think of. But anyway, the short story is that things are looking great, and it is looking like I have managed to slot into the existing build process with fairly minimal intrusive code, which bodes well for a future GCC 4 port attempt. :-) The remaining work I know of doesn't require any more intrusive code. BFN. Paul.
