2022-07-09gas: rename md_end to md_finishAlan Modra1-1/+1
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.
2022-05-27Remove use of bfd_uint64_t and similarAlan Modra1-5/+5
Requiring C99 means that uses of bfd_uint64_t can be replaced with uint64_t, and similarly for bfd_int64_t, BFD_HOST_U_64_BIT, and BFD_HOST_64_BIT. This patch does that, removes #ifdef BFD_HOST_* and tidies a few places that print 64-bit values.
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.

2021-03-29TRUE/FALSE simplificationAlan Modra1-20/+20
There is really no need to write code like "foo != 0 ? TRUE : FALSE" unless we had stupidly defined FALSE as something other than 0 or TRUE as something other than 1. The simpler "foo != 0" does just as well. Similarly "(condition == TRUE)" or "(condition == FALSE) can be simplified to "(condition)" and "(!condition)" respectively. I'll note that there is reason to use "integer_expression != 0" when assigning a bfd_boolean rather than the simpler "integer_expression", if you expect the variable to have 0 or 1 value. It's probably even a good idea to not rely on implicit conversion if bfd_boolean were _Bool. bfd/ * aoutx.h (aout_link_write_symbols): Don't cast boolean expression to bfd_boolean. * elf32-or1k.c (or1k_set_got_and_rela_sizes): Dont compare booleans against FALSE. * elf32-arc.c (name_for_global_symbol): Don't compare boolean to TRUE.

2020-08-23PR26513, 629310abec breaks assembling PowerPC Linux kernelsAlan Modra1-6/+5
Inserting with replacement is wrong for some gas hash table uses. This patch implements an htab_insert that conditionally replaces, and similarly for str_hash_insert. str_hash_insert with replace=0 is roughly equivalent to the older hash_insert, and str_hash_insert with replace=1 to the older hash_jam, but return values are different. I found it useful to know whether the slot was occupied prior to inserting/replacing. I've also reinstated the fatal errors on messing up opcode tables with duplicates.

2018-07-30Add support for the C_SKY series of processors.Andrew Jenner1-0/+7299
This patch series is a new binutils port for C-SKY processors, including support for both the V1 and V2 processor variants. V1 is derived from the MCore architecture while V2 is substantially different, with mixed 16- and 32-bit instructions, a larger register set, a different (but overlapping) ABI, etc. There is support for bare-metal ELF targets and Linux with both glibc and uClibc. This code is being contributed jointly by C-SKY Microsystems and Mentor Graphics. C-SKY is responsible for the technical content and has proposed Lifang Xia and Yunhai Shang as port maintainers. (Note that C-SKY does have a corporate copyright assignment on file with the FSF.) Mentor Graphics' role has been cleaning up the code, adding documentation and additional test cases, etc, to address issues we anticipated reviewers would complain about. bfd * Makefile.am (ALL_MACHINES, ALL_MACHINES_CFILES): Add C-SKY.
