Essentially, libstdc++ testsuite results are being lost because the
`libstdc++.log' is being overwritten by `check-abi'.
The regression is caused by this patch:
2005-05-12 Mark Mitchell <[EMAIL PROTECTED]>
2005-04-04 Mark Mitchell <[EMAIL PROTECTED]>
* testsuite/Makefile.am (check-local): Remove.
(curent_symbols.txt): Likewise.
(check-abi): Do not depend on current_symbols.txt.
* testsuite/Makefile.in: Regenerated.
* testsuite/libstdc++-abi/abi.exp: Build current_symbols.txt.
2005-04-01 Mark Mitchell <[EMAIL PROTECTED]>
* testsuite/Makefile.am (noinst_PROGRAMS): Remove.
(site.exp): Write out the path to the baseline file.
(check-abi): Use DejaGNU.
(check-abi-verbose): Remove.
* testsuite/Makefile.in: Regenerated.
* testsuite/abi_check.cc (main): Check the return value from
compare_symbols.
* testsuite/testsuite_abi.cc (compare_symbols): Return a value.
* testsuite/testsuite_abi.h (compare_symbols): Adjust prototype.
* testsuite/libstdc++-abi/abi.exp: New file.
2004-03-19 Phil Edwards <[EMAIL PROTECTED]>
* testsuite/Makefile.am (site.exp): New target, based on that
created by automake. Also set libiconv.
I'm not sure what the right fix is. Will try to investigate.
