[Qemu-devel] [PATCH v1 5/9] target-arm/translate-a64.c: Use extract32 in disas_ldst_reg_imm9

[Edgar E. Iglesias]

From: "Edgar E. Iglesias" <address@hidden>

Use extract32 instead of open coding the bit masking when decoding
is_signed and is_extended. This streamlines the decoding with some
of the other ldst variants.

No functional change.
