- * Generic dwarf analysis helpers

+ * - Since struct pt_regs is defined differently for user and kernel,

+ * field name of user's pt_regs), we make REG_OFFSET_NAME to accept
+ * both string name and reg field name.

+ * - Since accessing x86_32's pt_regs from x86_64 building is difficult
+ * and vise versa, we simply fill offset with -1, so
+ * get_arch_regstr() still works but regs_query_register_offset()
+ * returns error.
+ * The only inconvenience caused by it now is that we are not allowed
+ * to generate BPF prologue for a x86_64 kernel if perf is built for
+ * x86_32. This is really a rare usecase.

+ * gen-insn-x86-dat.sh script, make perf, and then run the test.
+ *
+ * If the test passes %0 is returned, otherwise %-1 is returned. Use the
