2022-07-09gas: rename md_end to md_finishAlan Modra1-2/+2
Currently md_end is typically used for some final actions rather than freeing memory like other *_end functions. Rename it to md_finish, and rename target implementation. The renaming of target functions makes it possible to find them all with "grep md_finish", eg. md_mips_end is renamed to mips_md_finish, not md_mips_finish. This patch leaves a number of md_end functions unchanged, those that either do nothing or deallocate memory, and calls them late. The idea here is that target maintainers implement md_end functions to tidy memory, if anyone cares. Freeing persistent memory in gas is not at all important, except that it can hide more important memory leaks, those that happen once per some frequent gas operation, amongst these unimportant memory leaks. * as.c (main): Rename md_end to md_finish. * config/tc-alpha.c, * config/tc-alpha.h, * config/tc-arc.c, * config/tc-arc.h, * config/tc-arm.c, * config/tc-arm.h, * config/tc-csky.c, * config/tc-csky.h, * config/tc-ia64.c, * config/tc-ia64.h, * config/tc-mcore.c, * config/tc-mcore.h, * config/tc-mips.c, * config/tc-mips.h, * config/tc-mmix.c, * config/tc-mmix.h, * config/tc-msp430.c, * config/tc-msp430.h, * config/tc-nds32.c, * config/tc-nds32.h, * config/tc-ppc.c, * config/tc-ppc.h, * config/tc-pru.c, * config/tc-pru.h, * config/tc-riscv.c, * config/tc-riscv.h, * config/tc-s390.c, * config/tc-s390.h, * config/tc-sparc.c, * config/tc-sparc.h, * config/tc-tic4x.c, * config/tc-tic4x.h, * config/tc-tic6x.c, * config/tc-tic6x.h, * config/tc-v850.c, * config/tc-v850.h, * config/tc-xtensa.c, * config/tc-xtensa.h, * config/tc-z80.c, * config/tc-z80.h: Similarly. * output-file.c (output_file_close): Call md_end.

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.

2019-02-10gas: Pass max_bytes to TC_FRAG_INITH.J. Lu1-1/+1

2017-11-27gas: xtensa: rewrite xg_relax_trampolineMax Filippov1-1/+0
Replace linked list of trampoline frags with an ordered array, so that instead of indexing fixups trampolines could be indexed. Keep each array in the trampoline_seg structure, so there's no need to rebuild it for every new processed segment. Don't run relaxation for each trampoline frag, instead run it for each fixup in the current segment that needs relaxation at the beginning of each relaxation pass. This way the complexity of this process drops from about O(n^2 * m) to about O(log n * m), where n is the number of trampoline frags and m is the number of fixups that need relaxation in the segment. gas/ 2017-11-27 Max Filippov <jcmvbkbc@gmail.com> * config/tc-xtensa.c (trampoline_index): New structure.

2016-03-31make xtensa_section_rename () take const char *Trevor Saunders1-1/+1
Xtensa uses it in several macros passing it a literal string, so its convenient for the argument type to be const char *. However some of the code in symbols.c seems to assume tc_canonicalize_symbol_name () will return a non const pointer, and some other target's implementations even modify the argument, so it seems best to return a char * which means casting away const on the argument when we return it instead of another string. gas/ChangeLog: 2016-03-31 Trevor Saunders <tbsaunde+binutils@tbsaunde.org> * config/tc-xtensa.c (struct rename_section_struct): Make old_name const.
