Now it is about time to publish the fifth progress report on porting musl on RISC-V. Last week, the toolchain itself has been built for RISC-V and running on Spike, and libc-test  can be executed with it now. I posted the result of tests on . The REPORT.txt file contains all error messages of failed tests, both run-time ones and compile-time ones. Some failures are expected since musl on x86_64 also does the same ones (e.g. errors in src/api/fcntl.c), but there are some unexpected errors too. I guess that the "warning: <the name of a header> is shorter than expected" warning indicates bugs in arch-dependent part of I/O functions or system calls (or kernel?) and it causes syntax errors in the same compilation unit. Moreover, some tests triggers a "signal 11" error (segmentation fault) in libc. I added some logs to . They are bugs in the port, obviously. I am working on them. The good news is, anyway, some results are *better than x86_64*, especially in math functions :-) (probably the cause is the difference in the floating-point precision, though. it is usual in float tests...) It takes long, long time to get but finally I have a (seems-to-be) working test suite for the port. I will continue to debug and fix the port using the result. Stay tuned! : http://nsz.repo.hu/git/?p=libc-test : https://gist.github.com/omasanori/ee828369aea844ac7fdfdc8362953299 -- Masanori Ogino
