It looks like:
.macro note name, type .balign 4 .int 2f - 1f # n_namesz .int 4f - 3f # n_descsz .int \type # n_type .balign 4 1: .asciz "\name" 2: .balign 4 3: .endm .macro enote 4: .balign 4 .endm
so it allows you to put arbitrary stuff in the desc part of the note. The downside is that its a little more cumbersome syntactically for the common case.
