Given the MicroBlaze GCC patch to support DWARF EH and so allow glibc to
build, which I've extracted from the location people pointed to here,
cleaned up a bit and posted on gcc-patches for review
<https://gcc.gnu.org/ml/gcc-patches/2017-01/msg00041.html>, some glibc
fixes are also needed to get reasonably clean compilation test results
with build-many-glibcs.py.
I'll send four such patches for review in separate messages. Given those
four - and that GCC patch, and the two architecture-independent patches
for building glibc tests with GCC 7 that are pending review
<https://sourceware.org/ml/libc-alpha/2017-01/msg00070.html>
<https://sourceware.org/ml/libc-alpha/2017-01/msg00071.html> - this
reduces the failures for MicroBlaze to just elf/check-execstack. As with
hppa and ia64 where that test also fails (hppa also has a failure of
elf/check-textrel), this is probably best addressed by someone with
architecture expertise (it's possible that XFAILing as for MIPS makes
sense, but an appropriate architecture-specific comment needs writing for
the XFAIL if so). But while such architecture maintainer / expert action
is needed for that failure, these four patches do at least get us closer
to the goal of clean compilation test results for all glibc configurations
so that regressions can more readily be detected.
