I was testing building several gcc compilers in blfs and ran into some
issues. Just looking at gcc, I'm getting the following:
=== gcc Summary ===
# of expected passes 96351
# of unexpected failures 50
# of unexpected successes 39
# of expected failures 270
# of unsupported tests 1395
I've used the same instructions we used in LFS, but there I got:
=== gcc Summary ===
# of expected passes 93302
# of expected failures 261
# of unsupported tests 1368
To me there is an issue that the total number of tests is not the same.
The source package is the same. The difference is that I now have
additional packages installed like valgrind and gdb.
All the FAIL and XPASS entries are in one testsuite:
testsuite/gcc.dg/guality/guality.exp
The actual entries are only from a couple of programs:
XPASS example.c 3 times
XPASS guality.c 8 times
XPASS inline-params.c 5 times
XPASS pr41353-1.c 8 times
XPASS pr41447-1.c 8 times
XPASS pr41616-1.c 7 times
FAIL pr43051-1.c 2 times
FAIL pr54200.c 1 time
FAIL pr54519-?.c 15 times
FAIL vla-?.c 32 times
Looking at gcc's bugzilla, I see similar results from 4.8.1 from as late
as last May and even some for 4.8.2 (pre-release) from this month.
The question becomes how to address this in the book. Any suggestions?
