Hi,
This is reposting of glibc port to ARC processors from synopsys.
The original posting was a while back [1]. The issues at the time were
(1). Need for working upstream gcc/binutils (vs. the github forks)
(2). Too many testsuite failures.
All the ducks seem to be in a row now, with last remaining gcc patch backported to
gcc-8-branch last week [2] and testsuite failures tended to/reduced significantly.
(a) build-many-glibcs.py check results are clean
| Summary of test results:
| 1173 PASS
| 15 XFAIL
|
| PASS: glibcs-arc-linux-gnu check
(b) Full testsuite ran in a cross compile setup using buildroot on HSDK development
platform.
Summary of test results:
24 FAIL
5124 PASS
27 UNSUPPORTED
19 XFAIL
| FAIL: localedata/sort-test # Needs more RAM:
| FAIL: stdio-common/bug22 # Needs more RAM: 2 GB memory
| FAIL: sunrpc/bug20790 # missing cpp on target
| FAIL: nptl/test-mutexattr-printers # need Python3 and target GDB on target

| FAIL: posix/tst-getaddrinfo5 # DNS server not configured
| FAIL: posix/globtest # require same user on target and host
| FAIL: elf/check-localplt # passes for build-many-glibcs.py
# buildroot builds with slightly different toggles (-Os)
# such that gcc generates an extra memcpy PLT call
| FAIL: gmon/tst-gmon-pie-gprof
| FAIL: gmon/tst-sprofil
| FAIL: posix/tst-spawn
| FAIL: posix/tst-spawn-static
| FAIL: nptl/tst-cond16
| FAIL: nptl/tst-cond17
| FAIL: nptl/tst-umask1
| FAIL: nptl/tst-setuid2
| FAIL: nss/bug-erange
| FAIL: nss/tst-nss-test3
The full log for above can be found at [3]
Bulk of failures are due to cross test setup and/or RAM accessible on target.
We are analysing the other failures and will tend to them as we go along.
(c) Code was rebased off of master yesterday. Please review and comment.
(d) We currently only support soft float ABI, although I'm working on hard float
and hopefully will have it ready sometime during the review of this series
Thx,
-Vineet
