* Update year range in copyright notice of binutils filesAlan Modra2023-01-011-1/+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.
* Update year range in copyright notice of binutils filesAlan Modra2022-01-021-1/+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.

* opcodes: discriminate endianness and insn-endianness in CGEN portsJose E. Marchesi2020-06-041-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The CGEN support code in opcodes accesses instruction contents using a couple of functions defined in cgen-opc.c: cgen_get_insn_value and cgen_put_insn_value. These functions use the "instruction endianness" in the CPU description to order the read/written bytes. The process of writing an instruction to the object file is: a) cgen_put_insn_value ;; Writes out the opcodes. b) ARCH_cgen_insert_operand insert_normal insert_1 cgen_put_insn_value ;; Writes out the bytes of the ;; operand. Likewise, the process of reading an instruction from the object file is: a) cgen_get_insn_value ;; Reads the opcodes. b) ARCH_cgen_extract_operand extract_normal extract_1 cgen_get_insn_value ;; Reads in the bytes of the ;; operand. As can be seen above, cgen_{get,put}_insn_value are used to both process the instruction opcodes (the constant fields conforming the base instruction) and also the values of the instruction operands, such as immediates. This is problematic for architectures in which the endianness of instructions is different to the endianness of data. An example is BPF, where instructions are always encoded big-endian but the data may be either big or little. This patch changes the cgen_{get,put}_insn_value functions in order to get an extra argument with the endianness to use, and adapts the existin callers to these functions in order to provide cd->endian or cd->insn_endian, whatever appropriate. Callers like extract_1 and insert_1 pass cd->endian (since they are reading/writing operand values) while callers reading/writing the base instruction pass cd->insn_endian instead. A few little adjustments have been needed in some existing CGEN based ports: * The BPF assembler uses cgen_put_insn_value. It has been adapted to pass the new endian argument. * The mep port has code in mep.opc that uses cgen_{get,put}_insn_value. It has been adapted to pass the new endianargument. Ditto for a call in the assembler. Tested with --enable-targets=all. Regested in all supported targets. No regressions. include/ChangeLog: 2020-06-04 Jose E.

* opcodes/cgen: Rework calculation of shift when inserting fieldsAndrew Burgess2016-02-021-3/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The calculation of the shift amount, used to insert fields into the instruction buffer, is not correct when the following conditions are all true: - CGEN_INT_INSN_P is defined, and true. - CGEN_INSN_LSB0_P is true - Total instruction length is greater than the length of a single instruction word (the instruction is made of multiple words) - The word offset is non-zero (the field is outside the first word) When the above conditions are all true, the calculated shift fails to take account of the total instruction length. After this commit the calculation of the shift amount is split into two parts, first we calculate the shift required to get to BIT0 of the word in which the field lives, then we calculate the shift required to place the field within the instruction word. The change in this commit only effects the CGEN_INT_INSN_P defined true case, but changes the code for both CGEN_INSN_LSB0_P true, and false. In the case of CGEN_INSN_LSB0_P being false, the code used to say: shift = total_length - (word_offset + start + length); Now it says: shift_to_word = total_length - (word_offset + word_length); shift_within_word = word_length - start - length; shift = shift_to_word + shift_within_word; From which we can see that in all cases the computed shift value should be unchanged. In the case of CGEN_INSN_LSB0_P being true, the code used to say: shift = (word_offset + start + 1) - length; Now it says: shift_to_word = total_length - (word_offset + word_length); shift_within_word = start + 1 - length; shift = shift_to_word + shift_within_word; In the case where 'total_length == word_length' AND 'word_offset == 0' (which indicates an instruction of a single word), we see that the computed shift value will be unchanged. However, when the total_length and word_length are different, and the word_offset is non-zero then the computed shift value will be different (and correct). opcodes/ChangeLog: * cgen-ibld.in (insert_normal): Rework calculation of shift. * epiphany-ibld.c: Regenerate. * fr30-ibld.c: Regenerate. * frv-ibld.c: Regenerate. * ip2k-ibld.c: Regenerate. * iq2000-ibld.c: Regenerate. * lm32-ibld.c: Regenerate. * m32c-ibld.c: Regenerate. * m32r-ibld.c: Regenerate. * mep-ibld.c: Regenerate. * mt-ibld.c: Regenerate. * or1k-ibld.c: Regenerate. * xc16x-ibld.c: Regenerate. * xstormy16-ibld.c: Regenerate.
