            Bug ID: 60411
           Summary: ADA canadian cross build fails.
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: ada
          Assignee: unassigned at gcc dot gnu.org
          Reporter: bernd.edlinger at hotmail dot de

I start with build=host=x86_64-unknown-linux-gnu target=arm-linux-gnueabihf 

../gcc-4.9-20140302/configure --prefix=/home/ed/gnu/arm-linux-gnueabihf-linux64
--target=arm-linux-gnueabihf --enable-languages=c,c++,fortran,ada
--with-arch=armv7-a --with-tune=cortex-a9 --with-fpu=vfpv3-d16
--with-float=hard


that one works.


But when I build build=x86_64-unknown-linux-gnu host=target=arm-linux-gnueabihf

../gcc-4.9-20140302/configure --prefix=/home/ed/gnu/arm-linux-gnueabihf-cross
--host=arm-linux-gnueabihf --target=arm-linux-gnueabihf
--enable-languages=c,c++,fortran,ada --with-arch=armv7-a --with-tune=cortex-a9
--with-fpu=vfpv3-d16 --with-float=hard


this build fails:

I'll try that on monday,

but how about linux-androideabi?

isn't that one broken now?

OK,

the cross build for arm-linux-gnueabihf succeeds again.

So I will close this tracker now.

Thanks,

BUT if I look at these lines in gcc/ada/gcc-interace/Makefile.in:

# ARM android
ifeq ($(strip $(filter-out arm% linux-androideabi,$(target_cpu)

So they use the same system.ads, which now links with a-exexpr-gcc.adb;
Should'nt this target now also use EH_MECHANISM=-gcc or -arm?

Great.

Yes, android should also use
  EH_MECHANISM=-arm

I'll make that change.

--- Comment #11 from John Marino <gnugcc at marino dot st> ---
Eric,
Thanks for these commits.  However, I'm still unable to build
arm-aux-linux-androideabi cross-compiler target after 209227.

This is the current error:
s-osinte.ads:593:07: component "sa_flags" overlaps "sa_mask" at line 592

This happens when a-dynpri.adb is being compiled.  s-osinte.ads is
s-osinte-android.ads of course.

I think this is a direct consequence of #include <asm/signal.h> at sigtramp.h

s-ointe-android.ads, lines 590-594:
   for struct_sigaction use record
      sa_handler at Linux.sa_handler_pos range 0 .. Standard'Address_Size - 1;
      sa_mask    at Linux.sa_mask_pos    range 0 .. 1023;
      sa_flags   at Linux.sa_flags_pos   range 0 .. Standard'Address_Size - 1;
   end record;

asm/signal.h (NDK, API 15):
typedef unsigned long sigset_t;
struct sigaction {
 union {
 __sighandler_t _sa_handler;
 void (*_sa_sigaction)(int, struct siginfo *, void *);
 } _u;
 sigset_t sa_mask;
 unsigned long sa_flags;
 void (*sa_restorer)(void);
};

So it does seem that struct_sigaction record isn't correct after all.
John

Hi Eric,
The compiler builds happily now.
It started right into ACATS testing and has passed the first 3 chapters
flawlessly (with the current setup ACATS takes hours because each test is
SCP'd/SSH'd to the device, but I'm going to improve the remote testing soon).

Thanks,
John

Hi Eric,
In the end, there were 6 failures.  It appears that the ARM unwinder isn't
quite right yet.  After 2314 passes, the six ACATS failures were:

C52103x
C52104x
C52104y
c74004a (hung)
cb1010c
cb1010d

It's not the ARM unwinder, it's the stack checking, see:

ah sorry, I always seem to conclude wrongly that stack checking requires unwind
support.  I'm not sure why I always conflate those two things.

So this patch was proposed 9 months ago but never got committed?  Or was it
only partially committed?

Will stack-check support get added soon?
Thanks,
John

Yes, it does, but it first needs to be fully functional.

Never reviewed and therefore not installed, I'll resubmit it at some point.

Hi Eric,
When I tried to build the ARMv5 cross compiler (-march=armv5te) I get the
following error:

/tmp//cc5BKnWK.s: Assembler messages:
/tmp//cc5BKnWK.s:31: Error: selected processor does not support Thumb mode
`stmfd sp!,{r2,r3,lr}'
/tmp//cc5BKnWK.s:46: Error: lo register required -- `ldmfd sp,{r2,r3,pc}'
gmake[8]: *** [sigtramp-armdroid.o] Error 1


Does this mean effectively nothing lower than ARMv7 can build
arm-*-linux-androideabi?  I don't know which ARM arch supports ldmfd
sp,{r2,r3,pc} but I assume ARMv5 and lower doesn't.

Apparently so, but it should be quite easy to fix this in sigtramp-armdroid.c
by means of some preprocessor magic.

To follow up, I reworked the testsuite handler to reduce the test times from 6
hours to about 15 minutes, so I've since re-run ACATS several times.  There are
only 5 failures.  I can't reproduce the hung c74004a test, it's executing fine
now.

So it's only the stack-check related tests that are failing.

This statement is a little ambiguous to me, which is the current situation?

A) There are no plans to alter sigtramp-android.c to support ARM architectures
below ARMv7.  Patches would be accepted though.
B) There are no plans to alter sigtramp-android.c to support ARM architectures
below ARMv7.  Patches will not be accepted, so to support ARMv5 requires local
modification
C) We are planning to alter sigtramp-android.c to support earlier ARM
architectures, please be patient!

If scenario C, when / what version of GCC?

Thanks!

I guess the closest match is A.
