2022-01-04T03:14:01Z

This is the OpenRISC port for glibc that I have been working on.

Changes since v4:
- Fix suggestion from Joseph Myers
- Remove libnsl.abilist
- Fixed suggestions from Adhemerval:
- Use Elf32_Addr and Elf32_Sym on link.h and sotruss-lib.c.
- Remove the superflous atomic typedefs on atomic-machine.h.
- Add the _dl_find_object on libc.abilist.
- Update wording for the NEWS entry.
- Other fixes
- Update date to 2022
- Remove uneeded REGSIZE
- Remove trailing newlines in Makefile
- Fix space vs tabs indentation in sysdep.h

Changes since v3:
- Fix suggestion from Paul Eggert
- Fix typo pore/port
- Fixed suggestions from Adhemerval:
- Used ENTRY/END asm macros where missing
- Remove block in dl-machine.h suggesting LD_PROFILE
- Remove jmp_buf-macros.h macros and use new default.
- Remove tcb-offsets.sym file and Makefile reference.
- Remove tcb-offsets.h include in tls.h.
- Define lib-audit register layout inline with other architectures.
- Fix usage of locally defined register in or1k_get_got. Also, fixup
indentation when using or1k_get_got.
- Cleanup abilists after rebasing, adding rseq and removing
empty files.
- Remove prctl and other unused entries in the linux Makefile.
- Fix STACK_ALIGN to 4 bytes, from incorrect copy-n-paste 16 bytes.
- Use default pthreadtypes-arch.h.
- Mention only soft-float supported in NEWS.
- Remove sysdeps/unix/sysv/linux/or1k/bits/timesize.h and use new
default.

Changes since v2:
- Fixed suggestions from Joseph Myers:
- Fix comment style, and description on top of each file
- Make sure macros have parentheses when needed,
- Bump required kernel down to 5.4.0 and document
- Regenerate arch-syscall.h
- Fixed suggestions from Adhemerval:
- Remove kernel_stat.h
- Just set MMAP2_PAGE_UNIT to 8K
- Remove ioctl.c and syscall.c files
- Update TCB alignment to 32 bytes

Changes since v1:
- Update api's as suggested by Florian
- Remove hard float support
- Updates to get all tests passing
- Split patch into managable bits similar to recent ARC port

Test Results:

build-many-glibcs.py:

PASS with mainline ang gcc-11.

Full test suite:

This time I ran the test suite with timeout of 300 and with patch for forcing
O_LARGEFILE in open64 [0]. The test has one failure but it seems like flaky
test as it passed after the second run.
