2026-01-23	perf disasm: Don't include C files from the arch directory	Ian Rogers
	Move the arch instructions.c files into appropriately named files in annotate-arch in the util directory. Don't #include to compile the code, switch to building the files and fix up the #includes accordingly. Move powerpc specific disasm code out of disasm.c and into annotate-powerpc.c. Declarations and static removed as appropriate for the code to compile as separate compilation units. The e_machine and e_flags set up is moved to the disasm.c architectures array so that later patches can sort by them.

2026-01-23	perf disasm: Constify use of 'struct ins_op'	Ian Rogers
	The 'struct ins_op' holds variables to function pointers that are read but not written. Change uses to be for a "const struct ins_op *" version to capture this immutability.

2024-11-09	perf disasm: Add e_machine/e_flags to struct arch	Ian Rogers
	Currently functions like get_dwarf_regnum only work with the host architecture. Carry the elf machine and flags in struct arch so that in disassembly these can be used to allow cross platform disassembly.
