2022-09-12ld: pe: Apply review suggestions on the existing exports/imports arraysMartin Storsjö1-2/+4
Use a separate explicit max_exports/imports field, instead of deducing it from the number of allocated elements. Use a named constant for the incremental growth of the array. Use bool instead of int for boolean values. Remove an unnecessary if statement/scope in the def_file_free function. Add more verbose comments about parameters, and about insertion into an array of structs. Generally use unsigned integers for all array indices and sizes. The num_exports/imports fields are kept as is as signed integers, since changing them to unsigned would require a disproportionate amount of changes ti pe-dll.c to avoid comparisons between signed and unsigned. Simply use xrealloc instead of a check and xmalloc/xrealloc; xrealloc can take NULL as the first parameter (and does a similar check internally). (This wasn't requested in review though, but noticed while working on the code.)
2022-09-12ld: pe: Improve performance of object file exclude symbol directivesMartin Storsjö1-1/+1
Store the list of excluded symbols in a sorted list, speeding up checking for duplicates when inserting new entries. This is done in the same way as is done for exports and imports (while the previous implementation was done with a linked list, based on the implementation for aligncomm). When linking object files with excluded symbols, there can potentially be very large numbers of excluded symbols (just like builds with exports can have a large number of exported symbols). This improves the link performance somewhat, when linking with large numbers of excluded symbols. The later actual use of the excluded symbols within pe-dll.c handles them via an unordered linked list still, though.

EXCLUDE_SYMBOLS keyword This was requested in review.
2022-08-01ld: Add support for a new option, -exclude-symbols, in COFF object file ↵Martin Storsjö1-0/+6
directives This maps to the same as ld's --exclude-symbols command line option, but allowing specifying the option via directives embedded in the object files instead of passed manually on the command line.
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.

2018-04-04Speed up direct linking with DLLs on Windows (2/2).Eric Botcazou1-0/+10
This patch deals with the generation of the import library on the fly. The implementation is inefficient because the linker makes a lot of calls to realloc and memmove when importing the symbols in order to maintain a sorted list of symbols. This is fixable by relying on the fact that, for every linked DLL, the list of symbols it exports is already sorted so you can import them en masse once you have found the insertion point. ld/ * deffile.h (def_file_add_import_from): Declare.
