glibc-2.11.1 lfs6.6rc1 configparms can cause more test failures

[Robert L. Inglis]

I compiled this same set of sources except using kernel 2.6.32.5 using lfs-svn-20100126-28 and only had the one ignored posix/annexc test error.

Tonight I seen the lfs6.6rc1 on the website so I started setting up a new build.

Using the command: case uname -m in

i?86) echo "CFLAGS += -march=i486 -mtune=native -O3 -pipe" > configparms ;;

esac

Produced the following error log: root:/sources/glibc-build# grep Error ../glibc-check-log make[2]: sources/glibc-build/posix/annexc.out Error 1 (ignored) make[2]: * sources/glibc-build/rt/tst-cpuclock2.out Error 1 make[1]: * [rt/tests] Error 2 make: * [check] Error 2

Removing the "-O3" from the same configparms command produced this error log: root:/sources/glibc-build# grep Error ../glibc-check-log-2 make[2]: sources/glibc-build/posix/annexc.out Error 1 (ignored) root:/sources/glibc-build#

Machine is AMD Phenom II 955 running a svn build from Christmas, using 2.6.32.2 kernel, if this is of any help.

What are the contents of /sources/glibc-build/rt/tst-cpuclock2.out?

We already say that The nptl/tst-clock2 and tst-attr3 tests sometimes fail, but we may need to update this to rt/tst-cpuclock2. It sounds like the same thing. It's a random failure in the the test, probably not the CFLAGS.

The rt/tst-cpuclock2 failure is an intermittent timing failure on some systems. This is now noted in the book at revision 9185.
