This patch set contains the glibc port for 32-bit RISC-V. This is based on the original work from Zong Li [1] and has been updated to use a 64-bit time_t. This requires a 5.4+ kernel and all of the testing has been done using the 5.4 stable kernel. Nothing fails when running ./scripts/build-many-glibcs.py (for all targets) on my x86-64 machine. This is the current list of tests that fail when running inside QEMU RV32 system emulation on the 5.4 kernel: FAIL: elf/tst-libc_dlvsym FAIL: elf/tst-libc_dlvsym-static FAIL: io/tst-lockf FAIL: login/check-abi-libutil FAIL: rt/tst-cpuclock2 FAIL: stdlib/tst-strfrom FAIL: stdlib/tst-strfrom-locale FAIL: support/tst-timespec ---Links--- 1:

weren't working - Update the coding style to match glibc - Update the __ASSUME_TIME64_SYSCALLS work to better match Lukasz's work RFC v3: - Remove all "Hack" patches - Incorporate upstream comments -

You should never have ABI test failures (or any compilation test failures)
in a port when it is submitted; a port with such failures is not ready for
inclusion in glibc.

This is a mistake. It is actually passing, this failure is from using an incorrect prefix. I have fixed it in my tests but forgot to remove it from the cover letter. Alistair > > -- > Joseph S.
