From: Alexander Graf @ 2012-09-10 11:40 UTC (permalink / raw)
To: qemu-devel qemu-devel; +Cc: Blue Swirl, Aurelien Jarno
From: Blue Swirl <blauwirbel@gmail.com>
Before splitting op_helper.c and helper.c in the next patches,
fix style issues. No functional changes.
Replace also GCC specific __FUNCTION__ with
standard __func__.
Don't init static variable (cpu_s390x_init:inited) with 0.

From: Alexander Graf @ 2012-09-10 11:40 UTC (permalink / raw)
To: qemu-devel qemu-devel; +Cc: Blue Swirl, Aurelien Jarno
From: Blue Swirl <blauwirbel@gmail.com>
Move floating point instructions to fpu_helper.c.
While exporting some condition code helpers,
avoid duplicate identifier conflict with translate.c.
Remove unused set_cc_nz_f64() in translate.c.

To: qemu-devel qemu-devel; +Cc: Blue Swirl, Aurelien Jarno
From: Blue Swirl <blauwirbel@gmail.com>
Add an explicit CPUState parameter instead of relying on AREG0.
Remove temporary wrappers and switch to AREG0 free mode.

To: qemu-devel qemu-devel; +Cc: Blue Swirl, Aurelien Jarno
From: Aurelien Jarno <aurelien@aurel32.net>
The load/store slow path has been broken in e141ab52d:
- We need to move 4 registers for store functions and 3 registers for
load functions and not the reverse.
- According to the s390x calling convention the arguments of a function
should be zero extended. This means that the register shift should be
done with TCG_TYPE_I64 to ensure the higher word is correctly zero
extended when needed.
I am aware that CONFIG_TCG_PASS_AREG0 is being removed and thus that
this patch can be improved, but doing so means it can also be applied to
the 1.1 and 1.2 stable branches.
