Hi,
some time ago boost-md was enabled for powerpc, but the proper context
create and switch functions from
pobj/boost_1_66_0/boost_1_66_0/libs/context/src/asm are not selected
and linked in.
The diff below fixes that part (and now powerdns recursor builds), but
the actual context switching does not work, it segfaults:
Program received signal SIGSEGV, Segmentation fault.
[Switching to thread 466468]
0xa85695f0 in jump_fcontext () from /usr/local/lib/libboost_context-mt.so.9.0
What I'm seeing is (in jump_ppc32_sysv_elf_gas.S/jump_context)
register r3 that is supposed to point to the memory that will receive
the transfer_t (the return value of jump_fcontext()) is 0.
# return transfer_t
stw %r6, 0(%r3)
stw %r5, 4(%r3)
Any suggestion os help is welcome,
Also, is there any point in enabling the boost-md lib for an arch if
this is not working?
