> Please submit a single patch to fix this bug.
How is
https://sourceware.org/ml/binutils/2019-12/msg00346.html
not a single patch? From that series
- patches 1 and 2 have been committed
- patch 3 demonstrates current (good as well as bad) behavior, to help show
more clearly how ...
- patch 4 fixes this issue (alongside other ones, but all by the same actual
code changes).
Would you _please_ take a _proper_ look at patches 3 and 4 of that series? It
is telling enough that you moved from an initial
"We can't change the encoding nor disallow it."
response to
"movzbw %al, %ecx
movzbw %al, %rcx
movzbl %al, %cx
movzbl %al, %rcx
movzbq %al, %cx
movzbq %al, %ecx
should be hard error. Clearly they are typos."
