2023-09-18Pass siginfo_t->si_addr to the reginfo_init() functionThomas Huth
On s390x, we need the si_addr from the siginfo_t to get to the address of the illegal instruction (the PSW address in the ucontext_t is already pointing to the next instruction there). So let's prepare for that situation and pass the si_addr to the reginfo_init() function everywhere.

2022-07-18aarch64: Use arch_init to configure sveRichard Henderson
Adjust some of the aarch64 code to look at the reginfo struct instead of looking at test_sve, so that we do not need to pass the --test-sve option in order to dump sve trace files. Diagnose EINVAL as either cpu or kernel does not support SVE.

2022-07-18Split RES_MISMATCH for registers and memoryRichard Henderson
By remembering the specific comparison that failed, we do not have to try again when it comes time to report. This makes the mem_used flag redundant. Also, packet_mismatch is now redundant with RES_BAD_IO. This means that the only thing that report_match_status does is to report on register status, so rename to report_mismatch_reg. Also, we know there is a failure, so don't return a status from the report.

2022-07-18Always write for --masterRichard Henderson
For trace, master of course must write to the file we create. For sockets, we can report mismatches from either end. At present, we are reporting mismatches from master. Reverse that so that we report mismatches from the apprentice, just as we do for trace.

2022-07-18Unify i/o functions and use RisuResultRichard Henderson
Push the trace check down from the function calling the reginfo function down into the i/o function. This means we don't have to pass a function pointer. Return a RisuResult from the i/o functions. This fixes a minor bug in send_register_info (even before the conversion to RisuResult), which returned the write_fn result directly.

2018-07-02risu_reginfo: introduce reginfo_size()Alex Bennée
In preparation for conditionally supporting SVE we need to be able to have different sized reginfos. This introduces reginfo_size() to abstract the size away to the code the actually knows.
