Hi all, as Tomas' ran into an OOM situation for the testsuite, I took over and bootstrapped gcc-16-20251214 on my rx2800 i2 in ca. mid December. Testsuite results are on [1]. I'll send a separate email for a possible discussion of these to the gcc list.
[1]: https://gcc.gnu.org/pipermail/gcc-testresults/2025-December/865397.html As shown in the testsuite results, the build time increased to some degree compared to older runs. For bootstrap this took nearly an hour longer (375 mins) compared to GCC 15.2.0 (319 mins; unfortunately I don't have the timing data for GCC 15.1.0, which is directly from trunk IINM). Together with the testsuite run, we are now close to 13 hours for the whole process on a rx2800 i2 w/1 x Itanium 2 9320 (4 cores, 8 threads) with everything done in `/dev/shm`. Only languages C and C++ were made. I used Linux v6.19-rc1 for bootstrapping gcc-16-20251214 and v6.17-rc1 for GCC 15.2.0. I'm unsure if the build time increase could be due to the used kernel, but I'll also look if cross compilations on GHA and locally show a comparable build time difference. Still, I wonder, do other arches show a similar increase in bootstrap timings for gcc-16-[...] compared to GCC 15.x.x? I'll try to follow this with another bootstrap and testsuite run until end of the month. Cheers, Frank
