PROVIDE_HIDDEN etc. were removed by 8733f6093c2b77502e7228503fc22024e51599b8 in order to support BSDs with older binutils (2.15). Maybe the ld scripts should be generated from a source file for example with CPP, so these lines could be tweaked. Doesn't guest base make the whole ld script thing useless? It's not implemented for Sparc though. > .init : { *(.init) } =0x47ff041f > .text : > { > -- > 1.7.7.3 > >
