Below is the results of glibc testsuite run for aarch64/lp64
I have been running the glibc testsuite as well. I have only run it on
an ILP32 enabled kernel. Using that kernel, top-of-tree glibc, and the
ILP32 glibc patches I have no LP64 regressions. There are 5 failures
in LP64 mode but I get them with vanilla top-of-tree glibc sources too.
They are:
nptl/eintr1 (I actually don't run this because it kills the 'make check')
debug/tst-backtrace5
debug/tst-backtrace6
nptl/tst-stack4
nptl/tst-thread_local1
In ILP32 mode I get 33 failures, they include the above failures (minus
nptl/tst-thread_local1) plus:
c++-types-check

conform/ISO11/stdint.h/conform

I am currently looking at these ILP32 regressions (starting with the
tls failures) to see if I can figure out what is happening with them.
Is there some progresses on it? We could collabrate to fix those issues.
