Suffix the instruction description of conditional branch extended mnemonics with their condition (e.g. "on A high").

2023-12-20s390: Use safe string functions and length macros in s390-mkopcJens Remus1-25/+52
Use strncpy() and snprintf() instead of strcpy() and strcat(). Define and use macros for string lengths, such as mnemonic, instruction format, and instruction description. This is a mechanical change, although some buffers have increased in length by one character. This has been confirmed by verifying that the generated opcode/s390-opc.tab is unchanged. opcodes/ * s390-mkopc.c: Use strncpy() and strncat().

2023-12-20s390: Enhance error handling in s390-mkopcJens Remus1-14/+35
When the s390-mkopc utility detects an error it prints an error message to strerr and either continues processing or exists with a non-zero return code. If it continues without detecting any further error the final return code was zero, potentially hiding the detected error. Introduce a global variable to hold the final return code and initialize it to EXIT_SUCCESS. Introduce a helper function print_error() that prints an error message to stderr and sets the final return code to EXIT_FAILURE. Use it to print all error messages. Return the final return code at the end of the processing. While at it enhance error messages to state more clearly which mnemonic an error was detected for. Also continue processing for cases where subsequent mnemonics can be processed. opcodes/ * s390-mkopc.c: Enhance error handling. Return EXIT_FAILURE in case of an error, otherwise EXIT_SUCCESS.

2023-12-04s390: Support for jump visualization in disassemblyJens Remus1-0/+12
Add support for jump visualization for the s390 architecture in disassembly: objdump -d --visualize-jumps ... Annotate the (conditional) jump and branch relative instructions with information required for jump visualization: - jump: Unconditional jump / branch relative. - condjump: Conditional jump / branch relative. - jumpsr: Jump / branch relative to subroutine. Unconditional jump and branch relative instructions are annotated as jump. Conditional jump and branch relative instructions, jump / branch relative on count/index, and compare and jump / branch relative instructions are annotated as condjump. Jump and save (jas, jasl) and branch relative and save (bras, brasl) instructions are annotated as jumpsr (jump to subroutine). Provide instruction information required for jump visualization during disassembly. The instruction type is provided after determining the opcode. For non-code it is set to dis_noninsn. Otherwise it defaults to dis_nonbranch. No annotation is done for data reference instructions (i.e. instruction types dis_dref and dis_dref2). Note that the instruction type needs to be provided before printing of the instruction, as it is used in print_address_func() to translate the argument value into an address if it is assumed to be a PC-relative offset. Note that this is never the case on s390, as print_address_func() is only called with addresses and never with offsets. The target of the (conditional) jump and branch relative instructions is provided during print, when the PC relative operand is decoded. include/ * opcode/s390.h: Define opcode flags to annotate instruction class information for jump visualization: S390_INSTR_FLAG_CLASS_BRANCH, S390_INSTR_FLAG_CLASS_RELATIVE, S390_INSTR_FLAG_CLASS_CONDITIONAL, and S390_INSTR_FLAG_CLASS_SUBROUTINE. Define opcode flags mask S390_INSTR_FLAG_CLASS_MASK for above instruction class information.

2020-07-29PR26279 Work around maybe-uninitialized warning in s390-mkopc.cAndreas Arnez1-1/+2
In s390-mkopc.c, the function insertExpandedMnemonic() searches for the first occurrence of '*' or '$' in the given mnemonic, and, if a match is found, chooses an extension table using a switch() on that character. The switch statement contains a default case that prints an error message and does not set the extension table. Although this case cannot occur, some GCC versions obviously conclude that the extension table might have been left uninitialized after the switch statement and consequently emit maybe-uninitialized warnings for the variables 'ext_table' and 'ext_table_length'. Circumvent the warning by handling the unreachable default case with abort(). opcodes/ * s390-mkopc.c (insertExpandedMnemonic): Handle unreachable default case with abort() instead of printing an error message and continuing, to avoid a maybe-uninitialized warning.
