Hi Tom.

I would like to remind this issue. I believe we can benefit from it as there
are packages that combine different pointer sizes:

firescope.log:[   50s] dwz: Multi-file optimization not allowed for differe=
nt
pointer sizes or endianity
gcc10.log:[10958s] dwz: Multi-file optimization not allowed for different
pointer sizes or endianity
gcc7.log:[ 5609s] dwz: Multi-file optimization not allowed for different
pointer sizes or endianity
gcc9.log:[ 3210s] dwz: Multi-file optimization not allowed for different
pointer sizes or endianity
kernel-debug.log:[12564s] dwz: Multi-file optimization not allowed for
different pointer sizes or endianity
kernel-default.log:[ 2057s] dwz: Multi-file optimization not allowed for
different pointer sizes or endianity
kernel-kvmsmall.log:[ 1163s] dwz: Multi-file optimization not allowed for
different pointer sizes or endianity
kernel-vanilla.log:[ 1432s] dwz: Multi-file optimization not allowed for
different pointer sizes or endianity
lmms.log:[ 1200s] dwz: Multi-file optimization not allowed for different
pointer sizes or endianity
rr.log:[  112s] dwz: Multi-file optimization not allowed for different poin=
ter
sizes or endianity
valgrind.log:[  736s] dwz: Multi-file optimization not allowed for different
pointer sizes or endianity

About multifile mode: I would print warning for a situation where just a si=
ngle
shared library (or executable)
is provided for a pointer width.
