2021-11-02target/hppa: Make hppa_cpu_tlb_fill sysemu onlyRichard Henderson
The fallback code in cpu_loop_exit_sigsegv is sufficient for hppa linux-user. Remove the code from cpu_loop that raised SIGSEGV. This makes all of the code in mem_helper.c sysemu only, so remove the ifdefs and move the file to hppa_softmmu_ss.

2021-02-05cpu: tcg_ops: move to tcg-cpu-ops.h, keep a pointer in CPUClassClaudio Fontana
we cannot in principle make the TCG Operations field definitions conditional on CONFIG_TCG in code that is included by both common_ss and specific_ss modules. Therefore, what we can do safely to restrict the TCG fields to TCG-only builds, is to move all tcg cpu operations into a separate header file, which is only included by TCG, target-specific code. This leaves just a NULL pointer in the cpu.h for the non-TCG builds. This also tidies up the code in all targets a bit, having all TCG cpu operations neatly contained by a dedicated data struct.

The TCG-specific CPU methods will be moved to a separate struct, to make it easier to move accel-specific code outside generic CPU code in the future. Start by moving tcg_initialize().

2019-04-18target: Simplify how the TARGET_cpu_list() printMarkus Armbruster
The various TARGET_cpu_list() take an fprintf()-like callback and a FILE * to pass to it. Their callers (vl.c's main() via list_cpus(), bsd-user/main.c's main(), linux-user/main.c's main()) all pass fprintf() and stdout. Thus, the flexibility provided by the (rather tiresome) indirection isn't actually used. Drop the callback, and call qemu_printf() instead. Calling printf() would also work, but would make the code unsuitable for monitor context without making it simpler.

2018-02-21target/*/cpu.h: remove softfloat.hAlex Bennée
As cpu.h is another typically widely included file which doesn't need full access to the softfloat API we can remove the includes from here as well. Where they do need types it's typically for float_status and the rounding modes so we move that to softfloat-types.h as well. As a result of not having softfloat in every cpu.h call we now need to add it to various helpers that do need the full softfloat.h definitions.
