x86: helper function + variables for templates' ->operand_types[] accesses
Introduces a helper function to access operand types, preparing for their removal from instruction templates.
As part of a series to refactor x86 instruction templates, Jan Beulich introduces a helper function get_operand_types in tc-i386.c. This function is designed to abstract away the direct access to insn_template->operand_types, serving as a preparatory step for moving this data out of the template structure itself. This change aims to reduce churn in subsequent modifications.
In Details
This patch is part of a series modifying how operand types are handled in the x86 assembler (gas). It introduces a helper function get_operand_types in gas/config/tc-i386.c. This function centralizes the retrieval of operand type information associated with an insn_template. Its primary purpose is to facilitate a future change where operand_types will no longer be directly embedded within insn_template structs, thus reducing churn during that refactoring.
- insn_template
- A structure defining the properties and operands of an assembly instruction.
- operand_types[]
- An array specifying the type of each operand for an instruction.
- helper function
- A function designed to perform a specific, often small, task that can be reused by other parts of the program.
- churn
- In software development, 'churn' refers to the amount of code that is changed or modified, often indicating instability or frequent refactoring.
