Once I had that interface, I thought I might as well enforce the requested alignment in user-only. There are plenty of cases where we ought to have been doing that for quite a while. This took rather more work than I imagined to start. Changes for v4: * Rebase, with some patches now upstream. * Rename the core function to cpu_loop_exit_sigbus. Changes for v3: * Updated tcg/{aarch64,ppc,s390,riscv,tci}. Changes for v2: * Cleanup prctl(2), add support for prctl(PR_GET/SET_UNALIGN). * Adjustments for ppc and sparc reporting address during alignment fault. r~ Richard Henderson (48): hw/core: Add TCGCPUOps.record_sigbus linux-user: Add cpu_loop_exit_sigbus linux-user/alpha: Remove EXCP_UNALIGN handling 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 target/s390x: Implement s390x_cpu_record_sigbus linux-user/hppa: Remove POWERPC_EXCP_ALIGN handling 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 target/arm: Use MO_128 for 16 byte atomics target/i386: Use MO_128 for 16 byte atomics target/ppc: Use MO_128 for 16 byte atomics target/s390x: Use MO_128 for 16 byte atomics target/hexagon: Implement cpu_mmu_index accel/tcg: Add cpu_{ld,st}*_mmu interfaces accel/tcg: Move cpu_atomic decls to exec/cpu_ldst.h target/mips: Use cpu_*_data_ra for msa load/store target/mips: Use 8-byte memory ops for msa load/store target/s390x: Use cpu_*_mmu instead of helper_*_mmu target/sparc: Use cpu_*_mmu instead of helper_*_mmu target/arm: Use cpu_*_mmu instead of helper_*_mmu tcg: Move helper_*_mmu decls to tcg/tcg-ldst.h tcg: Add helper_unaligned_{ld,st} for user-only sigbus linux-user: Split out do_prctl and subroutines linux-user: Disable more prctl subcodes Revert "cpu: Move cpu_common_props to hw/core/cpu.c" linux-user: Add code for PR_GET/SET_UNALIGN target/alpha: Reorg fp memory operations target/alpha: Reorg integer memory operations target/alpha: Implement prctl_unalign_sigbus target/hppa: Implement prctl_unalign_sigbus target/sh4: Implement prctl_unalign_sigbus linux-user/signal: Handle BUS_ADRALN in host_signal_handler tcg: Canonicalize alignment flags in MemOp tcg/i386: Support raising sigbus for user-only tcg/aarch64: Support raising sigbus for user-only tcg/ppc: Support raising sigbus for user-only tcg/s390: Support raising sigbus for user-only tcg/tci: Support raising sigbus for user-only tcg/riscv: Support raising sigbus for user-only tests/tcg/multiarch: Add sigbus.c docs/devel/loads-stores.rst | 52 ++- include/exec/cpu_ldst.h | 332 ++++++++------- include/exec/exec-all.h | 14 + include/hw/core/cpu.h | 4 + include/hw/core/tcg-cpu-ops.h | 23 + include/tcg/tcg-ldst.h | 79 ++++ include/tcg/tcg.h | 158 ------- linux-user/aarch64/target_prctl.h | 160 +++++++ linux-user/aarch64/target_syscall.h | 23 -
