His name may be on it, but it's actually supposed to be maintained by

I say "supposed" because apparently you can't find the answer to your
problem in the internals manual. That makes me wonder, could you
check whether MEM_ATTRS is documented in that manual? Because...
[0 a+0 S4 A32])) -1 (nil)
(nil))
...in your insn...:
(insn 9 6 10 (nil) (set (reg:SI 182)
(mem/f:SI (symbol_ref:SI ("a")) [0 a+0 S4 A32])) -1 (nil)
(nil))
...are the MEM_ATTRS for the SET_SRC of this set (the "(mem ...)"
bit). MEM_ATTRS are mainly used to store alias analysis information.
See rtl.h and rtl.def, and if you feel like this is your lucky day
then you could look at alias.c too.
