Bug#566234: [mips only] /usr/lib/libgnarl-4.4.so: undefined reference to `__gnat_alternate_stack'
Hi, I can reproduce the bug by using a qemu MIPS image [1]. Thanks to Aurélien Jarno for providing these images. The reproducer is simple: procedure Alternate is task Test; task body Test is begin null; end; begin null; end Alternate; r...@debian-mips:~/reproducers$ gnatmake alternate.adb gcc-4.4 -c alternate.adb gnatbind -x alternate.ali gnatlink alternate.ali /usr/lib/gcc/mips-linux-gnu/4.4.3/../../../../lib/libgnarl-4.4.so: undefined reference to `__gnat_alternate_stack' collect2: ld returned 1 exit status gnatlink: error when calling /usr/bin/gcc-4.4 gnatmake: *** link failed. The 'Test' task in the reproducer is just there to trigger linkage with GNARL. On MIPS, the reference to '__gnat_alternate_stack' in libgnarl cannot be resolved: /$ objdump -t /usr/lib/debug/usr/lib/libgnarl-4.4.so.1 | grep __gnat_alternate_stack *UND* __gnat_alternate_stack /$ objdump -t /usr/lib/debug/usr/lib/libgnat-4.4.so.1 | grep __gnat_alternate_stack /$ On amd64, '__gnat_alternate_stack' is provided in the bss of libgnat: ~$ objdump -t /usr/lib/debug/usr/lib/libgnarl-4.4.so.1 | grep __gnat_alternate_stack *UND* __gnat_alternate_stack ~$ objdump -t /usr/lib/debug/usr/lib/libgnat-4.4.so.1 | grep __gnat_alternate_stack 00520f80 g O .bss 4000 __gnat_alternate_stack The question is why '__gnat_alternate_stack' is not in the bss segment of libgnat on MIPS. The following #ifdef combination in gcc/ada/init.c looks suspicious: #elif defined (linux) (defined (i386) || defined (__x86_64__) \ || defined (__ia64__) || defined (__powerpc__)) ... #if defined (i386) || defined (__x86_64__) char __gnat_alternate_stack[16 * 1024]; /* 2 * SIGSTKSZ */ #endif ... #endif So gcc/ada/init.c does not provide '__gnat_alternate_stack' when compiled on MIPS, but s-osinte-linux.ads (which is linked into libgnarl) imports it. There seems to be some inconsistency about whether the alternate signal stack should be used on MIPS or not ... - reto [1] - http://people.debian.org/~aurel32/qemu/mips/ -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.
