Hello all,
This is the fourth issue of weekly report on porting musl to RISC-V
GSoC project.
This week, I have tried to run libc-test [1] on Spike with the
musl-based toolchain, but not succeeded. I found a minor problem with
recent cpp (I will report it to the maintainer of libc-test later) but
it is not the main issue preventing the test. I will continue
debugging this weekend.
There is no significant progress on the project this week. I will try
to contact other developers more and more to gain speed.
Have a nice weekend!

you have to s/-E/-E -P/ in the makefile
i was reluctant to do this upstream as it is a non-standard flag.

Thank you for letting me know!

If gcc isn't planning to fix this, I think we should find a good
out-of-the-box workaround in libc-test. That would probably be either
a probe for gcc needing -P, or a filter to undo whatever mangling gcc
does without -P. It seems like a fairly trivial sed script could do
the latter.

Just pin minimum gcc version to 5

libc-test does not depend on gcc much less a particular gcc version.
Ability to apply tests with different compilers is fairly important
since, for some interfaces, a buggy compiler might transform how
they're invoked in invalid ways that result in breakage, and these
sorts of bugs are useful to be able to track down.
