Description Jan-Jaap van der Heijden 2009-02-05 11:50:14 UTC 
Compiling the the most trivial program with GCC (using the SGI linker) results in warnings :

$ gcc -o hello hello.c
ld: WARNING 84: /usr/local/gnu/lib/gcc/mips-sgi-irix5.3/4.3.3/libgcc.a is not used for resolving any symbol.
ld: WARNING 84: /usr/local/gnu/lib/gcc/mips-sgi-irix5.3/4.3.3/libgcc.a is not used for resolving any symbol.
ld: WARNING 84: /usr/local/gnu/lib/gcc/mips-sgi-irix5.3/4.3.3/libgcc_eh.a is not used for resolving any symbol.

In IRIX6, this is prevented by setting the linker option '-dont_warn_unused' before linking libgcc, and unsetting it again afterward.

This trivial patch assumes the patch for PR39104 has also been applied, but they are otherwise unrelated.

Mine.
Comment 3 Rainer Orth 2010-04-22 15:07:04 UTC 
Discovered independently and fixed for 4.5.0.
