[Bug 1889288] [NEW] aarch64 BICS instruciton doesn't set flags


From: Robert

Date: Tue, 28 Jul 2020 17:05:59 -0000

Public bug reported:

When reading the source for translate-a64.c here:

https://github.com/qemu/qemu/blob/a466dd084f51cdc9da2e99361f674f98d7218559/target/arm/translate-a64.c#L4783

I noticed that it does not appear to call gen_logic_CC for the BICS
instruction so is not setting the flags as required. I haven't tried to
produce a test case for it but it seems like it might be a bug.
