* module/system/vm/linker.scm (make-linker-object): (linker-object-section-symbol): (linker-object-symbols*): Create a symbol to the start of a linker object. Hide it from the external linker-object-symbols* accessor. (segment-kind, count-segments): Sections without SHF_ALLOC don't get segments. (collate-objects-into-segments): Allow for #f segment types. If two sections have the same type and flags, leave them in the same order. (align): Allow for 0 alignment. (add-elf-objects): New helper: puts the ELF data structures (header, segment table, and section table) in sections of their own. This lends a nice clarity and conceptual unity to the linker. (relocate-section-header, allocate-segment): Lay out segments with congruent, contiguous addresses, so that we can just mmap the file and if debugging sections that are not in segments are present, they can be lazily paged in if needed by the kernel's VM system. (link-elf): Refactor to use the new interfaces. * test-suite/tests/linker.test: Update to expect the additional sections for the header and section table. |
