| |
v4: -- Rebased on 6.4rc1 -- Fix problem about "perf probe -x /lib64/libc.so.6 malloc"
v3: -- Check atomic instructions in insns_not_supported() -- Remove five DIE_* definitions in kdebug.h
v2: -- Move the functions to inst.c in patch #1 -- Pass around union for insns_not_supported(), insns_need_simulation() and arch_simulate_insn()
v1: -- Split the RFC patch #2 into two patches -- Use larch_insn_gen_break() to generate break insns for kprobes and uprobes -- Pass around instruction word instead of union for insns_not_supported(), insns_need_simulation() and arch_simulate_insn() to avoid type conversion for callers -- Add a simple test case for uprobes in the commit message
Tiezhu Yang (6): LoongArch: Move three functions from kprobes.c to inst.c LoongArch: Add larch_insn_gen_break() to generate break insns LoongArch: Use larch_insn_gen_break() for kprobes LoongArch: Add uprobes support LoongArch: Check atomic instructions in insns_not_supported() LoongArch: Remove five DIE_* definitions in kdebug.h
