Comment (by ken@…):
I've now done a build, test, DESTDIR install with gdb installed - using
the shipped LLVM.
{{{
./configure --prefix=/usr --docdir=/usr/share/doc/rust-1.16.0 --enable-
dist-host-only
./x.py build
./x.py test
DESTDIR=/some/path ./x.py dist --install
}}}
That --enable-dist-host-only ensures files for e.g. AArch64, ARM, MIPS,
PowerPC, Sparc, SystemZ are only compiled, not installed (no option to
prevent them getting compiled).
This seems to do the right thing, but is (of course) much slower building
LLVM. The tests took 22m25 on this machine (about 8.5 SBU) - in the
previous build without gdb the tests were only just over 10 minutes.
Unfortunately, 10 of hte gdb tests still failed.
I think this is now ready to give it a go (I suspect that I will probably
need to build cargo before I can use this for firefox, and maybe there is
still some problem that will stop it working, but it looks as if it might
work.
Summary of build sizes and SBUs (all with 4 cores)
configure, make using shared system LLVM about 2.3G (369M installed), 15
SBU
configure, rustbuild using static system LLVM about 2.1G (264M installed),
11 SBU
configure, rustbuild using shipped LLVM about 3.5G (288M installed), 20
SBU.
So, in an ideal world static linking is best for this, and using system
LLVM.
In reality, we have already moved LLVM to 4.0 (and the next version will
apparently be inflated to 5.0) but it seems unlikely that rust will cope
with newer versions by the time we need to use it.
