Split out host signal handing from accel/tcg/user-exec.c to linux-user/host/arch/host-signal.h - Replace TCGCPUOps.tlb_fill with TCGCPUOps.record_sigsegv for user-only - Add TCGCPUOps.record_sigbus for user-only - Remove a lot of target-specific cpu_loop handling for signals, now accomplished with generic code. ---------------------------------------------------------------- Richard Henderson (60): accel/tcg: Split out adjust_signal_pc accel/tcg: Move clear_helper_retaddr to cpu loop accel/tcg: Split out handle_sigsegv_accerr_write accel/tcg: Fold cpu_exit_tb_from_sighandler into caller configure: Merge riscv32 and riscv64 host architectures linux-user: Reorg handling for SIGSEGV linux-user/host/x86: Populate host_signal.h linux-user/host/ppc: Populate host_signal.h linux-user/host/alpha: Populate host_signal.h linux-user/host/sparc: Populate host_signal.h linux-user/host/arm: Populate host_signal.h linux-user/host/aarch64: Populate host_signal.h linux-user/host/s390: Populate host_signal.h linux-user/host/mips: Populate host_signal.h linux-user/host/riscv: Populate host_signal.h target/arm: Fixup comment re handle_cpu_signal linux-user/host/riscv: Improve host_signal_write linux-user/signal: Drop HOST_SIGNAL_PLACEHOLDER hw/core: Add TCGCPUOps.record_sigsegv linux-user: Add cpu_loop_exit_sigsegv target/alpha: Implement alpha_cpu_record_sigsegv target/arm: Use cpu_loop_exit_sigsegv for mte tag lookup target/arm: Implement arm_cpu_record_sigsegv target/cris: Make cris_cpu_tlb_fill sysemu only target/hexagon: Remove hexagon_cpu_tlb_fill target/hppa: Make hppa_cpu_tlb_fill sysemu only target/i386: Implement x86_cpu_record_sigsegv target/m68k: Make m68k_cpu_tlb_fill sysemu only target/microblaze: Make mb_cpu_tlb_fill sysemu only target/mips: Make mips_cpu_tlb_fill sysemu only target/nios2: Implement nios2_cpu_record_sigsegv linux-user/openrisc: Abort for EXCP_RANGE, EXCP_FPE target/openrisc: Make openrisc_cpu_tlb_fill sysemu only target/ppc: Implement ppc_cpu_record_sigsegv target/riscv: Make riscv_cpu_tlb_fill sysemu only target/s390x: Use probe_access_flags in s390_probe_access target/s390x: Implement s390_cpu_record_sigsegv target/sh4: Make sh4_cpu_tlb_fill sysemu only target/sparc: Make sparc_cpu_tlb_fill sysemu only target/xtensa: Make xtensa_cpu_tlb_fill sysemu only accel/tcg: Restrict TCGCPUOps::tlb_fill() to sysemu hw/core: Add TCGCPUOps.record_sigbus linux-user: Add cpu_loop_exit_sigbus target/alpha: Implement alpha_cpu_record_sigbus target/arm: Implement arm_cpu_record_sigbus linux-user/hppa: Remove EXCP_UNALIGN handling target/microblaze: Do not set MO_ALIGN for user-only target/ppc: Move SPR_DSISR setting to powerpc_excp target/ppc: Set fault address in ppc_cpu_do_unaligned_access target/ppc: Restrict ppc_cpu_do_unaligned_access to sysemu linux-user/ppc: Remove POWERPC_EXCP_ALIGN handling target/s390x: Implement s390x_cpu_record_sigbus target/sh4: Set fault address in superh_cpu_do_unaligned_access target/sparc: Remove DEBUG_UNALIGNED target/sparc: Split out build_sfsr target/sparc: Set fault address in sparc_cpu_do_unaligned_access accel/tcg: Report unaligned atomics for user-only accel/tcg: Report unaligned load/store for user-only tcg: Add helper_unaligned_{ld,st} for user-only sigbus linux-user: Handle BUS_ADRALN in host_signal_handler configure | 8 +- meson.build | 4 +- include/exec/exec-all.h | 55 +- include/hw/core/tcg-cpu-ops.h | 71 +- include/tcg/tcg-ldst.h | 5 + linux-user/host/aarch64/host-signal.h | 74 ++ linux-user/host/alpha/host-signal.h | 42 + linux-user/host/arm/host-signal.h | 30 + linux-user/host/i386/host-signal.h | 25 + linux-user/host/mips/host-signal.h | 62 ++ linux-user/host/ppc/host-signal.h | 25 + linux-user/host/ppc64/host-signal.h | 1 + linux-user/host/riscv/host-signal.h | 58 ++ linux-user/host/{riscv64 => riscv}/hostdep.h | 4 +- linux-user/host/riscv32/hostdep.h | 11 -
