perf disasm: Don't include C files from the arch directory

2026-01-23T19:58:38+00:00

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.

perf disasm: Constify use of 'struct ins_op'

2026-01-23T19:58:38+00:00

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.

perf disasm: Add e_machine/e_flags to struct arch

2024-11-09T16:39:13+00:00

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.

This patch add basic arch initialization and instruction associate
support for the csky CPU architecture.
