[Qemu-devel] [PATCH v2 3/3] target-tricore: Fix psw_read() clearing too many bits

[Bastian Koppelmann <kbastian@mail.uni-paderborn.de>]

psw_read() ought to sync the PSW value with the
cached status bits (C,V,SV,AV,SAV). For this the bits
are cleared in the PSW before they are written from the
cached bits. The clear mask is too big and clears two
additional bits.
