Hi, This patch fixes the bug PR50663, as I reported at: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50663
It records the missing information and add implicit set info to AVIN of the
basic block that implicit set is recorded for.
The patch has been tested on x86 and arm-none-eabi, and no failure
introduced.
Is it OK?
Thanks
