(struct Post_fde, Post_fdes): Declare. (Cie::write): Add post_fdes param. * ehframe.cc (Fde::write): Use plt_fde_location. (struct Post_fde): Define. (Cie::write): Stash FDEs added post merge mapping. (Eh_frame::add_ehframe_for_plt): Assert no new CIEs after mapping. Adjust Fde constructor call. Bump final_data_size_ for post map FDEs. (Eh_frame::do_sized_write): Arrange to write post map FDES after other FDEs. * powerpc.cc (Target_powerpc::do_plt_fde_location): New function. (Target_powerpc::has_glink): New function. (Target_powerpc::do_relax): Add eh_frame info for stubs. (struct Eh_cie, eh_frame_cie, glink_eh_frame_fde_64, glink_eh_frame_fde_32, default_fde): New data. (Stub_table::eh_frame_added_): New var. (Stub_table::find_long_branch_entry, stub_address, stub_offset): Make const. (Stub_table::add_eh_frame): New function. (Output_data_glink::add_eh_frame): New function. (Target_powerpc::make_glink_section): Call add_eh_frame. --- gold/target.h | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'gold/target.h') diff --git a/gold/target.h b/gold/target.h index d4b9d0f35d8..d75711e766d 100644 --- a/gold/target.h +++ b/gold/target.h @@ -240,6 +240,12 @@ class Target adjust_elf_header(unsigned char* view, int len) const { return this->do_adjust_elf_header(view, len); } + // Return address and size to plug into eh_frame FDEs associated with a PLT. + void + plt_fde_location(const Output_data* plt, unsigned char* oview, + uint64_t* address, off_t* len) const + { return this->do_plt_fde_location(plt, oview, address, len); } + // Return whether NAME is a local label name.
