2012-03-14target-s390x: Don't overuse CPUStateAndreas Färber
Scripted conversion: sed -i "s/CPUState/CPUS390XState/g" target-s390x/*.[hc] sed -i "s/#define CPUS390XState/#define CPUState/" target-s390x/cpu.h Signed-off-by: Andreas Färber <afaerber@suse.de> Acked-by: Anthony Liguori <aliguori@us.ibm.com>

2012-02-28target-s390x: Clean includesStefan Weil
The change in cpu.h is needed when HOST_LONG_BITS is defined in qemu-common.h. Signed-off-by: Stefan Weil <sw@weilnetz.de>
2011-11-14s390x: add ldeb instructionAlexander Graf
While running perl, we encountered the ldeb instruction to be used, so we implement it :). Signed-off-by: Alexander Graf <agraf@suse.de>
2011-08-21Fix conversions from pointer to tcg_target_longStefan Weil
tcg_gen_exit_tb takes a parameter of type tcg_target_long, so the type casts of pointer to long should be replaced by type casts of pointer to tcg_target_long. These changes are needed for build environments where sizeof(long) != sizeof(void *), especially for w64. See 4b4a72e55660abf7efe85aca78762dcfea5519ad which fixed the same issue for the other targets.

Most exec-all.h include directives are now useless, remove them. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-06-03s390x: implement lrvgrAlexander Graf
The LRVGR instruction was missing. Implement it, so everyone's happy. Reported-by: Balazs Kutil <bkutil@novell.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2011-06-03s390x: free tmp explicitly in every opcode for disas_a5()Alexander Graf
The disas_a5() function provided a TCG tmp variable which was populated by the respective opcode implementations, but freed at the end of the function in generic code. That makes it really hard for code review, so let's move the freeing to the same scope as the actual allocation. Signed-off-by: Alexander Graf <agraf@suse.de>

2011-06-03target-s390x: Fix duplicate call of tcg_temp_new_i64Stefan Weil
tmp2 = tcg_temp_new_i64() is already executed unconditionally, so there is no need to call it a second time for 64 bit hosts. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2011-06-03target-s390x: Fix wrong argument in call of tcg_gen_shl_i64()Stefan Weil
tcg_gen_shl_i64 needs a 3rd argument of type TCGv_i64. Set tmp4 so it can be used here. v2: Don't call tcg_const_i64() inside of the loop because it creates additional code. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2011-05-20s390x: translate engine for s390x CPUAlexander Graf
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>
2011-05-20s390x: helper functions for system emulationAlexander Graf
When running system emulation, we need to transverse through the MMU and deliver interrupts according to the specification. This patch implements those two pieces and in addition adjusts the CPU initialization code to account for the new fields in CPUState. Signed-off-by: Alexander Graf <agraf@suse.de>
2011-04-20Remove unused function parameters from gen_pc_load and rename the functionStefan Weil
Function gen_pc_load was introduced in commit d2856f1ad4c259e5766847c49acbb4e390731bd4. The only reason for parameter searched_pc was a debug statement in target-i386/translate.c. Parameter puc was needed by target-sparc until commit d7da2a10402f1644128b66414ca8f86bdea9ae7c. Remove searched_pc from the debug statement and remove both parameters from the parameter list of gen_pc_load. As the function name gen_pc_load was also misleading, it is now called restore_state_to_opc. This new name was suggested by Peter Maydell, thanks. v2: Remove last parameter, too, and rename the function. v3: Fix [] typo in target-arm/translate.c. Fix wrong SHA1 object name in commit message (copy+paste error).

2011-04-18s390x: Prepare cpu.h for emulationAlexander Graf
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.

2009-12-05S/390 CPU fake emulationAlexander Graf
Because Qemu currently requires a TCG target to exist and there are quite some useful helpers here to lay the groundwork for out KVM target, let's create a stub TCG emulation target for S390X CPUs. This is required to make tcg happy. The emulation target itself won't work though. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
