[linuxsh-shmedia-dev] modutils-2.4.2

[Benedict R. G. <ben...@su...>]

hi,

i am currently porting modutils-2.4.2 to sh64 Linux and have a question
concerning the handling of relocations of instructions that are the
destination of an shmedia branch. 

the problem i am having is how to determine when the relocation is to be
included in an instruction that is an shmedia branch destination. if one
looks at the code in dl-machine.h it calculates the value of the
variable lsb, to be 1 or 0, by anding STO_SH5_ISA32 with the field
st_other in the symbol structure (Elf32_Sym) being relocated and this
result is then ored into the resulting value during the calculation the
of relocation. 

--- it is a little strange that we are using the st_other field as this
seems to be for symbol visibility! 

unfortunately unlike binutils and bfd the modutils does not use the bfd
library, instead choosing to implement its own symbol structure
(obj_symbol in obj.h) which does not contain a mapping to the symbol
visibility.

does any one have any ideas of what might be the best approach to
solving this problem?

ben.
