It is.And what's in the location lists? If it's DW_OP_fbreg, then I presume it's a GCC bug. According to my reading of the DWARF spec, anyway.
I added code to tell it when not to use fbreg, but i only told it not to use fbreg in the location expression when we were outputting the frame_base attribute.
However, it appears we don't output a frame base attribute for external procedures, so we need to tell it it can't use if we don't have a frame base attribute.
You just need to change when loc_descriptor is called with a second parameter of true/1 to fix this.
Do you have a patch I can try?
This may not fix all of them, but it should help.
It doesn't help tls_symbolic_operand at all.
