Hi,
Two days ago, the test suite started failing. Initially there were
hundreds of failing tests; now only seven remain.
They appear to be related to SystemZ.
Here's the last failed test:
********************

"s390x--linux-gnu" seems wrong: either there's a dash too many or
a
word too few.

The canonicalization of the triple (actually a quadruple) always print all fields, empty or not. I'm not sure what's going on, though. How are you building this? Is your repository clean? After "make clean", do you get the same error? cheers, --renato -------------- next part -------------- An HTML attachment was scrubbed...

After "make clean", do you get the same error?Yes, same error after "make clean all check-all". This is a configure build (I usually run "make happiness" each morning) on Ubuntu LTS 12.04 with gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) It was working fine three days ago.

To process major changes to the source tree like the addition of a completely new component, it seems to be necessary to explicitly re-run configure (or sometimes even remove the build directory completely and start from scratch). I've seen similar problems in the past (e.g. when the PowerPC assembler was added, or when the SystemZ target itself was added). For some reason, a simple "make" or "make clean" does not appear to detect that it needs to re-run configure. Can you try doing this manually on your build system? Bye, Ulrich

Though, our problem was a compilation error, I'll not be surprised if a fresh build directory fixes everything. cheers, --renato -------------- next part -------------- An HTML attachment was scrubbed...
