COVER: glibc port for 32-bit RISC-V (RV32)
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-ldconfig-ld_so_conf-update
FAIL: io/tst-lockf
FAIL: misc/test-errno-linux
FAIL: nss/tst-nss-files-hosts-long
FAIL: resolv/tst-resolv-res_init-thread
FAIL: stdio-common/bug22
FAIL: stdlib/tst-strfrom
FAIL: stdlib/tst-strfrom-locale
FAIL: sysvipc/test-sysvmsg
