The way it's being done right now is that 'make install'
installs to the /usr prefix. After that a tarball of this
prefix is created (via tar cJf gdc-triplet.txz /usr). I'm not
sure if that's suitable as a release as is because tar omits
the root / so the result will be extracted as usr/
There isn't a lot of time budget left in that task but it
should be possible to run some more scripts.
If the time limit won't suffice it should be possible to
cache /usr and move the tar ball script into a new task.
If it follows the convention of the existing packages, it
should be fine. e.g: tar extracts gdc into
'x86_64-unknown-linux-gnu/bin/gdc'
The tar ball is 443MiB. That's because it includes half the
docker container :)
You should be able to get yourself down to about ~30MB. ;-)
I'll see if there's any miscellaneous tweaks you can do, but the
most obvious one is `strip --strip-debug`.
The buildci script [1] uses hard coded --prefix=/usr and
lib-dirs=/usr/lib.
Is there a particular reason for that ?
Or, rather, could I just change it or introduce a variable
prefix in order to be able to use an isolated directory ?

IIRC, that top line just matches Debian/Ubuntu built gcc (in the
hope that no weirdness would happen when running testsuite).
Seems reasonable to break it out into a variable that can be
overridden by the CI.
Just looking at an old binary, the builder used
`--prefix=/home/build/share/cache/install/x86_64-unknown-linux-gnu`. Not saying that you should do the same, but the last part being the target triplet is the key.

It may only be a marginal gain, but I find that
--disable-libstdcxx-pch helps with speeding up incremental builds
(a long time is spent compiling headers in libstdc++).
