2023-10-11target/ppc: Remove references to gdb_has_xmlAkihiko Odaki
GDB has XML support since 6.7 which was released in 2007. It's time to remove support for old GDB versions without XML support.

2023-10-11hw/core/cpu: Return static value with gdb_arch_name()Akihiko Odaki
All implementations of gdb_arch_name() returns dynamic duplicates of static strings. It's also unlikely that there will be an implementation of gdb_arch_name() that returns a truly dynamic value due to the nature of the function returning a well-known identifiers. Qualify the value gdb_arch_name() with const and make all of its implementations return static strings.

2023-10-11target/arm: Move the reference to arm-core.xmlAkihiko Odaki
Some subclasses overwrite gdb_core_xml_file member but others don't. Always initialize the member in the subclasses for consistency. This especially helps for AArch64; in a following change, the file specified by gdb_core_xml_file is always looked up even if it's going to be overwritten later. Looking up arm-core.xml results in an error as it will not be embedded in the AArch64 build.

hvf_get_supported_cpuid() is only defined for x86 targets (in target/i386/hvf/x86_cpuid.c). Its declaration is pointless on all other targets. All the calls to it in target/i386/cpu.c are guarded by a call on hvf_enabled(), so are elided when HVF is not built in. Therefore we can remove the unnecessary function stub.

2023-10-03target/arm: Replace TARGET_PAGE_ENTRY_EXTRAAnton Johansson
TARGET_PAGE_ENTRY_EXTRA is a macro that allows guests to specify additional fields for caching with the full TLB entry. This macro is replaced with a union in CPUTLBEntryFull, thus making CPUTLB target-agnostic at the cost of slightly inflated CPUTLBEntryFull for non-arm guests. Note, this is needed to ensure that fields in CPUTLB don't vary in offset between various targets. (arm is the only guest actually making use of this feature.)

2023-09-29target/arm/hvf: Clean up local variable shadowingPhilippe Mathieu-Daudé
Per Peter Maydell analysis [*]: The hvf_vcpu_exec() function is not documented, but in practice its caller expects it to return either EXCP_DEBUG (for "this was a guest debug exception you need to deal with") or something else (presumably the intention being 0 for OK). The hvf_sysreg_read() and hvf_sysreg_write() functions are also not documented, but they return 0 on success, or 1 for a completely unrecognized sysreg where we've raised the UNDEF exception (but not if we raised an UNDEF exception for an unrecognized GIC sysreg -- I think this is a bug). We use this return value to decide whether we need to advance the PC past the insn or not. It's not the same as the return value we want to return from hvf_vcpu_exec(). Retain the variable as locally scoped but give it a name that doesn't clash with the other function-scoped variable.
