Mathieu Desnoyers reported that the STACK_FRAME_NON_STANDARD macro wasn't working with the lttng_filter_interpret_bytecode() function in the lttng-modules code. Usually the relocation created by STACK_FRAME_NON_STANDARD creates a reference to a section symbol like this: Offset Type Value Addend Name 000000000000000000 X86_64_64 000000000000000000 +3136 .text But in this case it created a reference to a function symbol: Offset Type Value Addend Name 000000000000000000 X86_64_64 0x00000000000003a0 +0 lttng_filter_interpret_bytecode To be honest I have no idea what causes gcc to decide to do one over the other. But both are valid ELF, so add support for the function symbol.
