Subject: opcodes: blackfin: mark push/pop insns with a P6/P7 range as illegal
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=775f1cf0c29d662e29905b5b06f0dc079ba10e5a;p=binutils-gdb.git

opcodes: blackfin: mark push/pop insns with a P6/P7 range as illegal

The push/pop multiple insn has a 3 bit field for the P register range,
but only values of 0...5 are valid (P0 - P5).  There is no such P6 or
P7 register, so mark these insns as illegal.
