2023-02-03bpf: fix error conversion from long unsigned int to unsigned int ↵Guillermo E. Martinez1-1/+1
[-Werror=overflow] Regenerating BPF target using the maintainer mode emits: .../opcodes/bpf-opc.c:57:11: error: conversion from ‘long unsigned int’ to ‘unsigned int’ changes value from ‘18446744073709486335’ to ‘4294902015’ [-Werror=overflow] 57 | 64, 64, 0xffffffffffff00ff, { { F (F_IMM32) }, { F (F_OFFSET16) }, { F (F_SRCLE) }, { F (F_OP_CODE) }, { F (F_DSTLE) }, { F (F_OP_SRC) }, { F (F_OP_CLASS) }, { 0 } } The use of a narrow size to handle the mask CGEN in instruction format is causing this error. Additionally eBPF `call' instructions constructed by expressions using symbols (BPF_PSEUDO_CALL) emits annotations in `src' field of the instruction, used to identify BPF target endianness. cpu/ * bpf.cpu (define-call-insn): Remove `src' field from instruction mask. include/ *opcode/cge.h (CGEN_IFMT): Adjust mask bit width. opcodes/ * bpf-opc.c: Regenerate.
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.
2022-05-12cgen: increase buffer for hash_insn_listAlan Modra1-5/+5
As was done for hash_insn_array in commit d3d1cc7b13b4. * cgen-dis.c (hash_insn_list): Increase size of buf. Assert size is large enough.
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.
2021-06-22opcodes: make use of __builtin_popcount when availableAndrew Burgess1-0/+4
This commit provides a small performance improvement when starting up CGEN based disassemblers by making use of __builtin_popcount. The #if check used in this commit was copied from bfd/elf32-arm.c where __builtin_popcount is also used. I ran into this code while investigating some GDB tests that would occasionally timeout. One of the reason these tests were having problems is that the m16c and m32c disassemblers take so long to initialise themselves. Speeding up count_decodable_bits helps, but is not a total solution. Still, this felt like an easy win which added minimal extra complexity, so I figure its worth doing. opcodes/ChangeLog: * cgen-dis.c (count_decodable_bits): Use __builtin_popcount when available.
