Extra 4.0 -fpic/-fPIC testsuite failures on i686-unknown-linux-gnu

2005-01-01 Thread Kaveh R. Ghazi 
Finally, here are the excess -fpic/-fPIC testsuite failures from
mainline on i686-pc-linux-gnu as noted here:
http://gcc.gnu.org/ml/gcc-testresults/2005-01/msg00027.html

I'd like some assistance categorizing them please.

A. Fixable in the testcase.
B. Expected failures, use dg-skip-if or equiv.
C. Real bugs in the compiler, file a PR.

Mainline also has all of the excess -fpic/-fPIC failures from 3.4.x, I
didn't bother to repeat them.  The ones below are all from new
testcases.  Because of that, I don't know if they are regressions.
(If it turns out they are PR-worthy I'll check later.)

Thanks,

This is expected as the function might be overridden in a different
TU (yes this is a weird case but it can happen).

Hi Kaveh,

I'm trying to help for the libstdc++-v3 failure: can you confirm that, in
order to reproduce, I should just add -fpic/-fPIC to the CXXFLAGS? Or,
please clarify, otherwise, thanks...

This is a rather new testcase that I adapted from the plain char 
counterpart.
I think it's just a bug in the testcases (present also in the char 
version actually):
In fact i1 is computed as:

   i1 = ctraits_type::length(array1);
but array1 is *not* zero terminated ;)

Any thoughts on {char,wchar_t}/13189.cc ?
 

Yes, I'm working on it: something is messed up wrt the includes
necessary when _GLIBCXX_USE___ENC_TRAITS: in normal
builds you don't notice because PCHs (which drag in everything)
are used when running the testsuite, invalidated by -fpic/-fPIC.
I should have something pretty soon...
Thanks for posting the actual error,
Paolo.
