I finish tried testsuit under Darwin x86_64, originally, I incorrectly
installed mpc: need "brew install libmpc", not "brew install mpc", and
also need "brew link libmpc" which I missed.

At present, except for libjave Throw_2.exe test, I guess all others are
OK, please help check the result below, thanks. 

If it passes checking, next, I shall try to fix libjava Throw_2 issue
within this month (others, include Throw_1 and Throw_3 are all OK).

Oh, sorry, I forgot to mention 2 things:

 - config with "--disable-multilibs", and I shall try normal configiure
   again (although I guess, it will also be OK), hope I can finish
   within 2 days.

 - And during test libjava, it will quit with error because of Throw_2,
   so I modified the related Makefile to skip it.

After try normal configure, get almost the same result, I guess, our
testsuite under Darwin x86_64 is OK.

If no any additional reply within a week, I shall continue to try to
analyze the libjava Throw_2 issue.

Libjava test failure Was: [PATCH] microblaze: microblaze.md: Use 'SI' instead of 'VOID' for operand 1 of 'call_value_intern'

Throw_2 is a test specially contrived to detect segfaults that are
not being correctly detected and turned into NullPointerException()s.
A failure indicates that the segfault signal handler is broken.

OK, thank, at present, it passes compiling (can generate 'Throw_2.exe'),
and after run it without any parameters, "1" is printed, but "2" is not
printed.

Under Fedora 20 x86_64, the same gcc code, it is OK ("2" can be printed),
but under Darwin x86_64, it is "Abort trap: 6" instead of. The related
code: "try{Double.parseDouble(str());}catch", and "str(){return null;}".

And I shall continue to try to analyze it (within this month), and 
welcome any additional ideas, suggestions, and completion for it,

Not every platform supports unwinding through signal handlers.  In x86
Linux there is some very clever code which interacts with the kernel to
allow this.

Excuse me, I am not quite familiar with Java, I guess what you said is:

 - The related feature need OS kernel support, if OS kernel does not
   support, it may report "Abort trap: 6" or others.

 - And OS kernel has feature to support "1" printed does not mean it
   also has feature to support "2" printed.

 - And I need try to make sure that my current Darwin kernel whether
   supports it or not.

If what I guess is incorrect, please let me know, thanks.

For me, whether Darwin kernel supports or not, we have to improve
current implementation (may be testsuite configure or Makefile) to
avoid testsuite breaking.


Thanks.

That sounds approximately right, but it's changed a lot since I last
looked.  It may be that the magic is in glibc rather than the kernel.

The testsuite isn't breaking: it's telling you something useful.

OK, thanks, I shall also notice about glibc when I try to analyze it,
e.g. need try to build and install upstream glibc instead of the Darwin
glibc (I am not quite sure whether I can do that, I guess I can).

Sorry it is breaked, at present, I temporarily skipped it and then can

You're missing what I'm saying.  The testuite is not broken.

You should be running "make -k check".

For me, "make -k check" is suitable for one sub-system (e.g. for cross
building, and mainly focus on gcc), but not for global check (full
non-cross building check):

 - "make check" is the standard check for global, so when find new
   issues (include environment construction), need stop in time.

 - If one sub-system wants to skip the known issue, it can mark it as
   'unexpected', or just simply return 0 to Makefile to let checking
   continue (I guess, most of other sub-system do in this way).

 - Or for other members (especially for newbies, e.g. me), he/she can
   not sure whether the environment construction for testsuite is OK or
   not:

     e.g. For our case, after build upstream glibc and let testsuite use
     it instead of Darwin glibc, all things may go OK. If really it is,
     it is environments construction (not testsuite or code) issue.

In our world, there is no sub-system, so, talk of such is outside the scope of gcc.

Let me repeat what he said differently.

You have two choices, fixing the port so that there are no unexpected failures or running check with -k.

I’d like to get to the point where all primary/secondary platforms can use make check directly, we’re not there yet.

The idea is that the single return value tells if if the suite passed or not.  This is an absolute measure, that, when achieved means one never has to compare previous/present results, just know that the suite passed.  Sometimes simple is better.

No sub-system, no global.

Theoretically, in each system (include gcc), always can be separated
into several 'sub-systems', and then 'global' means the system itself.

In our case, we say let 'global' pass checking means let gcc, gfortran,
g++, libjava ... all pass checking. But for mainly focus on constructing
environments, I will try to use upstream glibc instead of Darwin glibc:

 - If fix Throw_2, we know it is environments construction issue.

 - Else, I shall skip it (since "make -k check" should be OK).

And after finish testsuite under Darwin, within this month, I shall try
to find and send a patch for gcc, and pass testsuite under Darwin (it
seems it is not quite difficult to me).

It is really unlucky, The upstream glibc does not support Darwin! And
sorry, send patches to glibc is really out of my current border, so I
have to give up. :-(

And I guess, this thread can be ended, and next, I shall try to find a
patch for gcc, and let it pass testsuite under Darwin.
