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/inttypes.h/conform
conform/ISO11/stdint.h/conform
conform/ISO99/inttypes.h/conform
conform/ISO99/stdint.h/conform
conform/POSIX2008/inttypes.h/conform

nptl/tst-sem3
rt/tst-mqueue1
rt/tst-mqueue2
rt/tst-mqueue4
rt/tst-mqueue7
stdlib/tst-makecontext3

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.
