To: qemu-devel; +Cc: peter.maydell, aurelien, rth
We need to add some more logic to the CPU description to leverage emulation
of an s390x CPU. This patch adds all the required helpers, fields in CPUState
and constant definitions required for user and system emulation.
Signed-off-by: Alexander Graf <agraf@suse.de>
---
v1 -> v2:
- remove FPReg definition
- remove EXCP_EXECUTE_SVC in non user-mode
- add descriptions to more cc_ops
- add comment on time2tod
- remove redundant EXECUTE_SVC
- describe EXCP_EXT

To: qemu-devel; +Cc: peter.maydell, aurelien, rth
There are some instructions that can't (or shouldn't) be expressed by pure
tcg code. For those, we call into externally compiled C functions.
This patch implements those C functions.
Signed-off-by: Alexander Graf <agraf@suse.de>
---
v1 -> v2:
- new clock syntax
- use float_chs
- use float compare built-ins
- remove redundant EXECUTE_SVC

From: Alexander Graf @ 2011-03-29 13:29 UTC (permalink / raw)
To: qemu-devel; +Cc: peter.maydell, aurelien, rth
This is the main meat part of the patch set. It implements emulation for an
s390x CPU.
The code does all the optimizations that are common for TCG code:
- direct branches
- cc optimization
- unrolling of simple microcode loops
I'm still open for suggestions on speedups of course :).
Signed-off-by: Alexander Graf <agraf@suse.de>
---
v1 -> v2:
- don't pass env into DisasContext
- remove if 0'd code
- truncate at 80 chars
- enable disas debug by default (-d in_asm)
- remove explicit psw.addr advancing on SVC
