hi folks, i was interesting in tackling some problems gcc netbsd/vax has. it has some ICEs which are in reload phase. searching around, the answer to that is "switch to LRA first". Now, I don't quite know what that is yet, but I know I need to try to do it.
As an initial step, I need to sync the source code. netbsd/vax has some outstanding work on GCC. I've done this, and I can run programs built by this compiler: http://coypu.sdf.org/gcc-9-vax.diff (My tree has more detail on the changes done: https://github.com/gcc-mirror/gcc/compare/master...coypoop:vax ) Matt Thomas (the GCC VAX maintainer) is the author of most of these changes, I suspect he will not be very responsive by email. Not being the author, I might not be able to answer all the questions, but I can try my best. How do I get this across? comments? straight to gcc-patches? :-) I know Jeff Law did not like the change to builtins.md as being wrong. I can omit them, I forgot about it until typing this email :) caveat: had an ICE during reload in the build process, I hid it under the rug with -O0.
