I guess the closest match is A.

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!

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.

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

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.

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.

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

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

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

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

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  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_maskat Linux.sa_mask_posrange 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

Great.

Yes, android should also use
  EH_MECHANISM=-arm

I'll make that change.

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:
