Probably a Sun 'as' bug, a similar problem was reported on Solaris 7: http://gcc.gnu.org/install/specific.html GCC 4.0.0 is known to bootstrap on Solaris 8 with: as: Sun WorkShop 6 03/08/05 Compiler Common 6.0 Patch 114802-01 ld: Software Generation Utilities - Solaris Link Editors: 5.8-1.285 > Would it be possible to document this requirement in the platform pages? > http://gcc.gnu.org/install/specific.html#sparc-sun-solaris2 It is already documented in *-*-solaris2* that 2.15 is broken on the platform. > Speaking of the sparc-sun-solaris2* platform, I read: > GCC 3.4 changed the default debugging format from STABS > to DWARF-2 for 32-bit code on Solaris 7 and later.

Not sure whether the bug ID is correct though. -- Eric Botcazou
