2021-06-03target/ppc: fix single-step exception regressionLuis Pires1-3/+2
Commit 6086c75 (target/ppc: Replace POWERPC_EXCP_BRANCH with DISAS_NORETURN) broke the generation of exceptions when CPU_SINGLE_STEP or CPU_BRANCH_STEP were set, due to nip always being reset to the address of the current instruction. This fix leaves nip untouched when generating the exception.

Additionally, REQUIRE_64BIT when L=1 to match what is specified in The Programming Environments Manual: "For 32-bit implementations, the L field must be cleared, otherwise the instruction form is invalid." Some CPUs are known to deviate from this specification by ignoring the L bit [1]. The stricter behavior, however, can help users that test software with qemu, making it more likely to detect bugs that would otherwise be silent. If deemed necessary, a future patch can adapt this behavior based on the specific CPU model. [1] The 601 manual is the only one I've found that explicitly states that the L bit is ignored, but we also observe this behavior in a 7447A v1.2.

2021-06-03target/ppc: powerpc_excp: Consolidade TLB miss codeFabiano Rosas1-35/+2
The only difference in the code for Instruction fetch, Data load and Data store TLB miss errors is that when called from an unsupported processor (i.e. not one of 602, 603, 603e, G2, 7x5 or 74xx), they abort with a message specific to the operation type (insn fetch, data load/store). If a processor does not support those interrupts we should not be registering them in init_excp_<proc> to begin with, so that error message would never be used. I'm leaving the message in for completeness, but making it generic and consolidating the three interrupts into the same case statement body.

2021-06-03target/ppc: overhauled and moved logic of storing fpscrBruno Larsen (billionai)4-234/+65
Followed the suggested overhaul to store_fpscr logic, and moved it to cpu.c where it can be accessed in !TCG builds. The overhaul was suggested because storing a value to fpscr should never raise an exception, so we could remove all the mess that happened with POWERPC_EXCP_FP. We also moved fpscr_set_rounding_mode into cpu.c as it could now be moved there, and it is needed when a value for the fpscr is being stored directly.

2021-06-03target/ppc: added ifdefs around TCG-only codeBruno Larsen (billionai)4-6/+44
excp_helper.c, mmu-hash64.c and mmu_helper.c have some function declarations that are TCG-only, and couldn't be easily moved to a TCG only file, so ifdefs were added around them. We also needed ifdefs around some header files because helper-proto.h includes trace/generated-helpers.h, which is never created when building without TCG, and cpu_ldst.h includes tcg/tcg.h, whose containing folder is not included as a -iquote. As future cleanup, we could change the part of the configuration script to add those. cpu_init.c also had a callback definition that is TCG only and could be removed as part of a future cleanup (all the dump_statistics part is almost never used and will become obsolete as we transition to using decodetree).

2021-06-03target/ppc: used ternary operator when registering MASBruno Larsen (billionai)1-6/+3
The write calback decision when registering the MAS SPR has been turned into a ternary operation, rather than an if-then-else block. This was done because when building without TCG, even though the compiler will optimize away the pointers to spr_write_generic*, it doesn't optimize away the decision and assignment to the local pointer, creating compiler errors. This cleanup looked better than using ifdefs, so we decided to with it.

2021-05-26cpu: Rename CPUClass vmsd -> legacy_vmsdPhilippe Mathieu-Daudé1-1/+1
Quoting Peter Maydell [*]: There are two ways to handle migration for a CPU object: (1) like any other device, so it has a dc->vmsd that covers migration for the whole object. As usual for objects that are a subclass of a parent that has state, the first entry in the VMStateDescription field list is VMSTATE_CPU(), which migrates the cpu_common fields, followed by whatever the CPU's own migration fields are. (2) a backwards-compatible mechanism for CPUs that were originally migrated using manual "write fields to the migration stream structures". The on-the-wire migration format for those is based on the 'env' pointer (which isn't a QOM object), and the cpu_common part of the migration data is elsewhere. cpu_exec_realizefn() handles both possibilities: * for type 1, dc->vmsd is set and cc->vmsd is not, so cpu_exec_realizefn() does nothing, and the standard "register dc->vmsd for a device" code does everything needed * for type 2, dc->vmsd is NULL and so we register the vmstate_cpu_common directly to handle the cpu-common fields, and the cc->vmsd to handle the per-CPU stuff You can't change a CPU from one type to the other without breaking migration compatibility, which is why some guest architectures are stuck on the cc->vmsd form. New targets should use dc->vmsd. To avoid new targets to start using type (2), rename cc->vmsd as cc->legacy_vmsd. The correct field to implement is dc->vmsd (the DeviceClass one). See also commit b170fce3dd0 ("cpu: Register VMStateDescription through CPUState") for historic background.

2021-05-19target/ppc: Remove type argument from mmubooke_check_tlbRichard Henderson1-31/+13
We can now use MMU_INST_FETCH from access_type for this. Unify the I/D code paths, making use of prot_for_access_type.

2021-05-19target/ppc: Remove type argument from check_protRichard Henderson1-27/+6
We can now use MMU_INST_FETCH from access_type for this. Use prot_for_access_type to simplify everything.

2021-05-19target/ppc: Use MMUAccessType in mmu_helper.cRichard Henderson1-76/+85
This replaces 'int rw' with 'MMUAccessType access_type'. Comparisons vs zero become either MMU_DATA_LOAD or MMU_DATA_STORE, since we had previously squashed rw to 0 for code access.
