  "message": "perf annotate: add Alpha instruction support\n\nTeach perf annotate about the Alpha control-transfer instructions so jump/call/\nreturn arrows and cross-CPU annotation work for Alpha perf.data.\n\nAdd tools/perf/util/annotate-arch/annotate-alpha.c with arch__new_alpha() and an\nassociate_instruction_ops() that classifies:\n  call:   bsr, jsr, jsr_coroutine\n  ret:    ret\n  jump:   br, jmp, and the conditional branches beq/bne/blt/ble/bgt/bge/blbc/\n          blbs and fbeq/fbne/fblt/fble/fbgt/fbge\n  mov:    mov, fmov (objdump pseudos)\n\nEM_ALPHA is 0x9026, far too large to index the e_machine-keyed arch_new_fn[]\ntable in arch__find(), so select arch__new_alpha explicitly before the table\nlookup. Declare it in disasm.h and add the object to the annotate-arch Build.\n\nDisassembly itself comes from objdump/binutils, which already supports Alpha;\nthis provides perf\u0027s instruction-class metadata for annotation.\n",
