ASSERT NOT IMPLEMENTED hit in ARM Android: aarchxx/mangle.c:2534 "base reg is in the reglist"
Created by: sudakshina-das-arm
I am continuing on one of the crash reports #2465 (closed) and #2492 After @egrimley merged his patch of adding some missing instructions, the APKs that were earlier failing with the missing vmov.f32 instructions are all now failing with a signal 11. The modified debug version (refer to #2492 ) gave out
