2024-04-03elf: Use mmap to map in read-only sectionsH.J. Lu1-7/+1
There are many linker input files in LLVM debug build with huge string sections. All these string sections can be treated as read-only. But linker copies all of them into memory which consumes huge amount of memory and slows down linker significantly. Add _bfd_mmap_readonly_persistent and _bfd_mmap_readonly_temporary to mmap in reado-only sections with size >= 4 * page size. NB: All string sections in valid ELF inputs must be null terminated. There is no need to terminate it again and string sections are mmapped as read-only. * bfd.c (bfd_mmapped_entry): New. (bfd_mmapped): Likewise. (bfd): Add mmapped. * bfdwin.c (bfd_get_file_window): Use _bfd_pagesize. * cache.c (cache_bmmap): Remove pagesize_m1 and use pagesize_m1 instead. * elf.c (bfd_elf_get_str_section): Call _bfd_mmap_readonly_persistent instead of _bfd_alloc_and_read. Don't terminate the string section again. (get_hash_table_data): Call _bfd_mmap_readonly_temporary and _bfd_munmap_readonly_temporary instead of _bfd_malloc_and_read and free. (_bfd_elf_get_dynamic_symbols): Call _bfd_mmap_readonly_persistent instead of _bfd_alloc_and_read. Don't terminate the string section again. Call _bfd_mmap_readonly_temporary and _bfd_munmap_readonly_temporary instead of _bfd_malloc_and_read and free. (_bfd_elf_slurp_version_tables): Call _bfd_mmap_readonly_temporary and _bfd_munmap_readonly_temporary instead of _bfd_malloc_and_read and free. * elflink.c (bfd_elf_link_record_dynamic_symbol): Use bfd_malloc to get the unversioned symbol. * libbfd-in.h (_bfd_pagesize): New. (_bfd_pagesize_m1): Likewise. (_bfd_minimum_mmap_size): Likewise. (_bfd_mmap_readonly_persistent): Likewise. (_bfd_mmap_readonly_temporary): Likewise.

Define if undefined. * bfd-in2.h: Regenerated. * libbfd.h: Likewise.
2024-03-13bfd: Use MAP_FAILED for mmap failureH.J. Lu1-9/+1
Use MAP_FAILED, instead of ((void *) -1), for mmap failure and use ((void *) -1) only if MAP_FAILED is undefined. * bfdio.c (bfd_mmap): Replace (void *) -1 with MAP_FAILED for mmap failure. * bfdwin.c: Don't include <sys/mman.h>. (MAP_FILE): Removed. (bfd_get_file_window): Replace (void *) -1 with MAP_FAILED for mmap failure. * cache.c: Don't include <sys/mman.h>. (cache_bmmap): Replace (void *) -1 with MAP_FAILED for mmap failure. * opncls.c (opncls_bmmap): Likewise. * sysdep.h: Include <sys/mman.h> if HAVE_MMAP is define. (MAP_FILE): New. Defined as 0 if undefined. (MAP_FAILED): New. Defined as ((void *) -1) if undefined.
2024-01-04Update year range in copyright notice of binutils filesAlan Modra1-1/+1
Adds two new external authors to etc/update-copyright.py to cover bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then updates copyright messages as follows: 1) Update cgen/utils.scm emitted copyrights. 2) Run "etc/update-copyright.py --this-year" with an extra external author I haven't committed, 'Kalray SA.', to cover gas testsuite files (which should have their copyright message removed). 3) Build with --enable-maintainer-mode --enable-cgen-maint=yes. 4) Check out */po/*.pot which we don't update frequently.
2023-08-09Rename bfd_bread and bfd_bwriteAlan Modra1-1/+1
These were renamed from bfd_read and bfd_write back in 2001 when they lost an unnecessary parameter. Rename them back, and get rid of a few casts that are only needed without prototyped functions (K&R C).
2023-05-03Generated docs and include filesAlan Modra1-5/+59
bfd/doc/chew.c extracts documentation from source code comments annotated with keywords, and generates much of bfd.h and libbfd.h from those same comments. The docs have suffered from people (me too) adding things like CODE_FRAGMENT to the source to put code into bfd.h without realising that CODE_FRAGMENT also puts @example around said code into the docs. So we have random senseless things in the docs. This patch fixes that problem (well, the senseless things from CODE_FRAGMENT), moves most of the code out of bfd-in.h, and improves a few chew.c features. libbfd.h now automatically gets ATTRIBUTE_HIDDEN prototypes, and indentation in bfd.h and libbfd.h is better.
2023-01-01Update year range in copyright notice of binutils filesAlan Modra1-1/+1
The newer update-copyright.py fixes file encoding too, removing cr/lf on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and embedded cr in binutils/testsuite/binutils-all/ar.exp string match.
2022-01-02Update year range in copyright notice of binutils filesAlan Modra1-1/+1
The result of running etc/update-copyright.py --this-year, fixing all the files whose mode is changed by the script, plus a build with --enable-maintainer-mode --enable-cgen-maint=yes, then checking out */po/*.pot which we don't update frequently. The copy of cgen was with commit d1dd5fcc38ead reverted as that commit breaks building of bfp opcodes files.

2020-04-02coff-go32-exe: support variable-length stubsJan W. Jagersma1-0/+1
The stub size in GO32 executables has historically been fixed at 2048 bytes, due to hardcoded limitations in bfd. Recent patches to djgpp by Stas Sergeev (CC'd) have pushed the stub right up to this limit, so if any further expansion is desired, this must first be patched in bfd. This series includes three patches: The first changes the meaning of the bfd->origin field slightly, so that target code can use this to specify an offset into the file where the actual bfd is located. The second patch then uses this to enable support for variable-sized stubs in the coff-go32-exe format. The final patch is only a cleanup, it normalizes function and variable names in coff-stgo32.c so that they all begin with the same prefix. bfd * bfdio.c (bfd_bread, bfd_tell, bfd_seek, bfd_mmap): Always add bfd->origin to file offset. * bfdwin.c (bfd_get_file_window): Likewise. * bfd.c: Clarify the use of the bfd->origin field. * bfd-in2.h: Regenerate. * coff-i386.c: Don't include go32exe.h.
