Can DynamoRIO Add x86 labels to instructions?

[Galangkangin Gotera]

Hi,

Currently I am trying to write a tool that does adds some functionality when the address of a write matches a certain address in x86 architecture. Is it possible to add x86 labels to instrumentation? Something like this:

drutil_insert_get_mem_addr(drcontext, ilist, where, dst, reg_tmp, reg_ptr);

INSTR_CREATE_cmp(drcontext,  opnd_create_reg(reg_tmp), OPND_CREATE_MEMPTR(INTERESTED_MEMORY))

INTR_CREATE_jcc(drcontext,  OP_JNE, GO)

drx_buf_insert_load_buf_ptr(drcontext, buf, ilist, where, reg_ptr);

// ... more code to execute if reg_tmp == INTERESTED_MEMORY)

GO:

// ... continue execution from here whatever the result is

Thanks in advance.

Have you looked at INSTR_CREATE_label() (https://github.com/DynamoRIO/dynamorio/blob/master/core/ir/instr_create_shared_api.h#L162) ?
