2019-10-03bfd, ld: add CTF section linkingNick Alcock1-0/+1
This is quite complicated because the CTF section's contents depend on the final contents of the symtab and strtab, because it has two sections whose contents are shuffled to be in 1:1 correspondence with the symtab, and an internal strtab that gets deduplicated against the ELF strtab (with offsets adjusted to point into the ELF strtab instead). It is also compressed if large enough, so its size depends on its contents! So we cannot construct it as early as most sections: we cannot even *begin* construction until after the symtab and strtab are finalized. Thankfully there is already one section treated similarly: compressed debugging sections: the only differences are that compressed debugging sections have extra handling to deal with their changing name if compressed (CTF sections are always called ".ctf" for now, though we have reserved ".ctf.*" against future use), and that compressed debugging sections have previously-uncompressed content which has to be stashed away for later compression, while CTF sections have no content at all until we generate it (very late). BFD also cannot do the link itself: libctf knows how to do it, and BFD cannot call libctf directly because libctf already depends on bfd for file I/O. So we have to use a pair of callbacks, one, examine_strtab, which allows a caller to examine the symtab and strtab after finalization (called from elf_link_swap_symbols_out(), right before the symtabs are written, and after the strtab has been finalized), and one which actually does the emission (called emit_ctf simply because it is grouped with a bunch of section-specific late-emission function calls at the bottom of bfd_elf_final_link, and a section-specific name seems best for that). emit_ctf is actually called *twice*: once from lang_process if the emulation suggests that this bfd target does not examine the symtab or strtab, and once via a bfd callback if it does. (This means that non-ELF targets still get CTF emitted, even though the late CTF emission stage is never called for them). v2: merged with non-ELF support patch: slight commit message adjustments. v3: do not spend time merging CTF, or crash, if the CTF section is explicitly discarded. Do not try to merge or compress CTF unless linking. v4: add CTF_COMPRESSION_THRESHOLD. Annul the freed input ctf_file_t's after writeout: set SEC_IN_MEMORY on the output contents so a future bfd enhancement knows it could free it. Add SEC_LINKER_CREATED | SEC_KEEP to avoid having to add .ctf to the linker script. Drop now-unnecessary ldlang.h-level elf-bfd.h include and hackery around it. Adapt to elf32.em->elf.em and elf-generic.em->ldelf*.c changes. v5: fix tabdamage. Drop #inclusions in .h files: include in .c files, .em files, and use struct forwards instead. Use bfd_section_is_ctf inline function rather than SECTION_IS_CTF macro. Move a few comments. * Makefile.def (dependencies): all-ld depends on all-libctf. * Makefile.in: Regenerated. include/ * bfdlink.h (elf_strtab_hash): New forward. (elf_sym_strtab): Likewise. (struct bfd_link_callbacks <examine_strtab>): New. (struct bfd_link_callbacks <emit_ctf>): Likewise. bfd/ * elf-bfd.h (bfd_section_is_ctf): New inline function. * elf.c (special_sections_c): Add ".ctf". (assign_file_positions_for_non_load_sections): Note that compressed debugging sections etc are not assigned here. Treat CTF sections like SEC_ELF_COMPRESS sections when is_linker_output: sh_offset -1. (assign_file_positions_except_relocs): Likewise. (find_section_in_list): Note that debugging and CTF sections, as well as reloc sections, are assigned later. (_bfd_elf_assign_file_positions_for_non_load): CTF sections get their size and contents updated. (_bfd_elf_set_section_contents): Skip CTF sections: unlike compressed sections, they have no uncompressed content to copy at this stage. * elflink.c (elf_link_swap_symbols_out): Call the examine_strtab callback right before the strtab is written out. (bfd_elf_final_link): Don't cache the section contents of CTF sections: they are not populated yet. Call the emit_ctf callback right at the end, after all the symbols and strings are flushed out. ld/ * ldlang.h: (struct lang_input_statement_struct): Add the_ctf.

(ldemul_examine_strtab_for_ctf): Likewise. * ldlang.c: Include ctf-api.h. (CTF_COMPRESSION_THRESHOLD): New. (ctf_output): New. Initialized in... (ldlang_open_ctf): ... this new function. Open all the CTF sections in the input files: mark them non-loaded and empty so as not to copy their contents to the output, but linker-created so the section gets created in the target. (ldlang_merge_ctf): New, merge types via ctf_link_add_ctf and ctf_link. (ldlang_ctf_apply_strsym): New, an examine_strtab callback: wrap ldemul_examine_strtab_for_ctf.

(lang_process): Call ldlang_open_ctf, ldlang_merge_ctf, and lang_write_ctf. * ldmain.c (link_callbacks): Add ldlang_ctf_apply_strsym, ldlang_write_ctf_late. * emultempl/aix.em: Add ctf-api.h. * emultempl/armcoff.em: Likewise. * emultempl/beos.em: Likewise. * emultempl/elf.em: Likewise. * emultempl/generic.em: Likewise. * emultempl/linux.em: Likewise. * emultempl/msp430.em: Likewise. * emultempl/pe.em: Likewise. * emultempl/pep.em: Likewise. * emultempl/ticoff.em: Likewise. * emultempl/vanilla.em: Likewise. * ldcref.c: Likewise. * ldctor.c: Likewise. * ldelf.c: Likewise. * ldelfgen.c: Likewise. * ldemul.c: Likewise. * ldexp.c: Likewise. * ldfile.c: Likewise. * ldgram.c: Likewise. * ldlex.l: Likewise. * ldmain.c: Likewise. * ldmisc.c: Likewise. * ldver.c: Likewise. * ldwrite.c: Likewise. * lexsup.c: Likewise. * mri.c: Likewise. * pe-dll.c: Likewise. * plugin.c: Likewise. * ldelfgen.c (ldelf_emit_ctf_early): New.
