I think the use of this feature (label-attributes) here isn't

of basic blocks observed with GCC without this label attribute?

GCC does the same, but I wanted to have the exception stuff be in
.text.cold, but alas it doesn't do that. I left the attribute because of
it's descriptive value.

 Unless the cold attribute is helping move
("shrink-wrap"?) the basic block to a whole other section
(.text.cold.)?

I was hoping it would do that, but it doesn't on gcc-11.
