--- Comment #7 from Joshua Kinard <kumba at gentoo dot org> --- (In reply to Eric Botcazou from comment #6) > Please retry with the current 7 branch, it contains additional fixes. I did about a week ago. Tried building gcc-7-branch HEAD with both gcc-6.4.0 and gcc-5.3.0, and both failed in the same spot. If something was added in the last week, I can re-test. I also tried gcc-HEAD with gcc-6.4.0 and that also failed. FWIW, reversing PR59461 (some manual edits required) on gcc-7_1_0-release compiles cleanly, which is the first time that's happened on this machine under N32. Successful builds on this machine take about 8 hours. Fail builds....~3-4 hours. It's during stage2-bubble when compiling genrecog.c will bail out, claiming no more virtual memory (2GB RAM + 3GB of swap). So PR59461 clearly has some kind of issue on N32, with -march=mips3 or -march=r12000 (build machine is an SGI Octane w/ an R14000 CPU, so fairly old school). The only other working MIPS machine I have is an SGI O2 with a rare RM7000 CPU. But gcc on that thing takes about 2-3 days for a successful build. However, it is running O32 ABI under uclibc-ng, so odds are likely gcc-7.x would compile successfully.
