The processor function hooks and constants are ad hoc and need better documentation. -When a linker script uses @samp{SIZEOF_HEADERS}, the ELF backend must -guess at the number of program segments which will be required, in -@samp{get_program_header_size}. This is because the linker calls -@samp{bfd_sizeof_headers} before it knows all the section addresses and -sizes. The ELF backend may later discover, when creating program -segments, that more program segments are required. This is currently -reported as an error in @samp{assign_file_positions_for_segments}. - -In practice this makes it difficult to use @samp{SIZEOF_HEADERS} except -with a carefully defined linker script. Unfortunately, -@samp{SIZEOF_HEADERS} is required for fast program loading on a native -system, since it permits the initial code section to appear on the same -page as the program segments, saving a page read when the program starts -running. Fortunately, native systems permit careful definition of the -linker script. Still, ideally it would be possible to use relaxation to -compute the number of program segments. - @node BFD glossary @section BFD glossary @cindex glossary for bfd |
