We don't encourage use of #ifdef like that. It's better to have an
inline function defined everywhere and used unconditionally, for which
most systems have a dummy definition (see dl-machine-reject-phdr.h and
elf_machine_reject_phdr_p for an example - if you have a header for a
single function, you don't need to update lots of dl-machine.h headers,
just add a generic version - which has the comments detailing the
semantics of the function and when it's needed - and a MIPS version).
Thanks Joseph. It's been a while since I did a glibc patch and couldn't
remember the recommended approach.
Do you think I should add a whole new header for this? Or, since this
is directly related to the reject_phdr feature for MIPS and only MIPS
is affected then I could just add it to dl-machine-reject-phdr.h?
