this name is used by capstone and will lead to a build failure of QEMU, when capstone is enabled. So we rename it to tricore_has_feature(), to match has_feature() in translate.c.

2023-06-21target/tricore: Fix helper_ret() not correctly restoring PSWBastian Koppelmann
We are always taking the TRICORE_FEATURE_13 branch as every CPU has TRICORE_FEATURE_13. For CPUs with ISA > 1.3 we have to take the else branch. We fix this by inverting the condition. We check for TRICORE_FEATURE_131, which every CPU except TRICORE_FEATURE_13 CPUs have.

2018-04-11icount: fix cpu_restore_state_from_tb for non-tb-exit casesPavel Dovgalyuk
In icount mode, instructions that access io memory spaces in the middle of the translation block invoke TB recompilation. After recompilation, such instructions become last in the TB and are allowed to access io memory spaces. When the code includes instruction like i386 'xchg eax, 0xffffd080' which accesses APIC, QEMU goes into an infinite loop of the recompilation. This instruction includes two memory accesses - one read and one write. After the first access, APIC calls cpu_report_tpr_access, which restores the CPU state to get the current eip. But cpu_restore_state_from_tb resets the cpu->can_do_io flag which makes the second memory access invalid. Therefore the second memory access causes a recompilation of the block. Then these operations repeat again and again. This patch moves resetting cpu->can_do_io flag from cpu_restore_state_from_tb to cpu_loop_exit* functions. It also adds a parameter for cpu_restore_state which controls restoring icount. There is no need to restore icount when we only query CPU state without breaking the TB. Restoring it in such cases leads to the incorrect flow of the virtual time. In most cases new parameter is true (icount should be recalculated). But there are two cases in i386 and openrisc when the CPU state is only queried without the need to break the TB. This patch fixes both of these cases.

2018-01-25accel/tcg: add size paremeter in tlb_fill()Laurent Vivier
The MC68040 MMU provides the size of the access that triggers the page fault. This size is set in the Special Status Word which is written in the stack frame of the access fault exception. So we need the size in m68k_cpu_unassigned_access() and m68k_cpu_handle_mmu_fault(). To be able to do that, this patch modifies the prototype of handle_mmu_fault handler, tlb_fill() and probe_write(). do_unassigned_access() already includes a size parameter. This patch also updates handle_mmu_fault handlers and tlb_fill() of all targets (only parameter, no code change).

2017-12-27target/*helper: don't check retaddr before calling cpu_restore_stateAlex Bennée
cpu_restore_state officially supports being passed an address it can't resolve the state for. As a result the checks in the helpers are superfluous and can be removed. This makes the code consistent with other users of cpu_restore_state. Of course this does nothing to address what to do if cpu_restore_state can't resolve the state but so far it seems this is handled elsewhere. The change was made with included coccinelle script.

2016-12-20Move target-* CPU file into a target/ folderThomas Huth
We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.
