Be a bit more strict about what is accepted into mainline by building
with -Werror set for gcc builds.
Clang builds will get the same treatment soon.
Also turn off some ubsan compiles for some of the older arches where
there's very little value (and it probably doesn't work anyway).
This should cut down on the number of github builders, but having only
one per arch per toolchain per debug per ubsan. Still a lot, but working
on it.
Also means it automatically builds every project in the tree, instead of
just the curated list.
* Sometimes apt-get install qemu fails with fetch error, run apt-get
update first to mitigate
* unittest.py often fails due to app shell not started in 0.5s, increase
timeout
Remove clang-13 from the build list, since it's not present in ubuntu
24.04.
If someone thinks this is an issue, please drop an email and we can see
about adding it back.
-Don't try to compile any riscv targets on gcc 7.5.0 which is a bit too
old to deal with any of the newer ISA extensions.
-Stop building UBSAN on 7.5.0 builds since that's not particularly
useful.
This only builds a subset of all targets for now since the remaining
ones (32-bit targets) would require libgcc/compiler-rt for the 64-bit
integer and/or double-precision float helper functions.
Currently, only aarch64 targets build with clang, but with follow-up
this can be extended to include x86_64 and RISCV64.
Port to the really neat 68010 based board at https://rosco-m68k.com/
Port Features:
-10Mhz 68010
-1MB ram
-Dual UART + timer implemented as a 68c681 chip
-timer running at 1Khz, UART A for console
-interrupt driven RX support
Some amount of extending of the 68k exceptinon code was needed to
support the autovectored irqs that the 68681 uart uses. Added build
system support for 68010.
Switch to a more proper matrix. Build each of the projects in a list
with DEBUG=0 and DEBUG=2 and with two versions of the toolchain (7.5.0
and 11.2.0).
Sets things up to be easier to run things like unit tests in a later
patch.
Use the new github actions to replace the travis-ci builders which
seem to no longer work and are being removed.
This first stab is fairly rough, just matches the explicit matrix
that was in the travis-ci hooks, but at least gets back to a buildable
state again.
