s390: Instruction cleanups
Series of patches to clean up s390 instruction definitions and test cases in binutils.
This is the cover letter for a series of 20 patches that clean up various aspects of s390 instruction definitions and assembler test cases within binutils. The changes include enhancing opcode table headings, standardizing test names, and correcting operand validation for several instructions. This series prepares for future work on adding all instruction formats to .insn pseudo-mnemonics.
In Details
This patch series targets the s390 architecture support within the binutils assembler. It involves routine maintenance such as improving table headings, standardizing test case naming conventions, and fixing specific instruction operand validations. The series aims to improve code clarity and correctness and serves as a prerequisite for more extensive future changes.
