I posted build results showing the error is still present. I had a patch in the
previous version and it should apply.
Now I am a bit confused. This patch
https://git.rtems.org/rtems-source-builder/commit/?id=5a0dba77b13eec49f86ce3812fb74f65dfa1e98d
changes the GCC version from 9.1.0 to 9.2.0 on or1k, riscv, and x86_64.
I didn't change the patches:
https://git.rtems.org/rtems-source-builder/tree/rtems/config/tools/rtems-gcc-9.1.0-newlib-6661a67.cfg?id=5a0dba77b13eec49f86ce3812fb74f65dfa1e98d
The GCC bug doesn't seem to be a GCC 9.1.0 to 9.2.0 regression. In your
build log only riscv failed, or1k and x86_64 passed. Is this a sporadic
problem?
Since there will be probably no RTEMS 5 in the near future, maybe we should move
to GCC 9.2 in general.
This is a catch-22, I hope to start on the release process soon but things like
this add to the complexity and add to the time it takes.
If we do this on PowerPC, then the SPE is no longer supported.
Joel has stated many times in talks I have seen that we follow the architectures
GCC supports and if one is removed we remove support.
Does this mean 5.1 is the last version of RTEMS to support SPE?
This was my plan.
Should the specific BSPs be moved to tier 4 and marked for removal?
The SPE support should bit rot for a while. The chips are still in
production and used with RTEMS, e.g. by EPICS users.
On ARM a breaking change in compiler options is necessary.
What options are these?
ARM changed the FPU options in GCC 8 and later.
Also this seems back to front to me. Should all hosts be on 9.2.0 and those that
cannot have specific versions?
Only PowerPC should stay at GCC 7 until the next RTEMS release from my
point of view. Everything else can move on.
