Subject: [Qemu-devel] [PATCH v2 0/4] qom-cpu: Wrap set_pc hook and use in bootloaders
Date: Mon, 15 Jun 2015 22:46:04 -0700 [thread overview]
Message-ID: <cover.1434432813.git.crosthwaite.peter@gmail.com> (raw)
Wrap the CPUClass::set_pc fn hook in a caller helper to reduce
verbosity of calls. Simplify the call from the gdbstub.
Then use the call to abstract away the PC env fields from the ARM and
Microblaze bootloaders.
This moves towards the goal of minimising system level code of the CPU
env (and one step closer to common-obj'ing the bootloaders). There's a
long way to go (at least for ARM, not so far for MB), but this is a
small win in that direction.
This helps with multi-arch where the current thinking is to compile
out the maximum content possible from cpu.h. This removes program
counter definitions from the multi-arch cpu.h compile-in list.
changed since v1:
Remove thumb changes

qom: cpu: Add wrapper to the set-pc hook
gdbstub: Use cpu_set_pc helper
arm: boot: Use cpu_set_pc
microblaze: boot: Use cpu_set_pc
