Hi,

What does this expression mean ? DW_OP_breg7+8

This expression is associated to DW_AT_frame base in a loclist. 
DW_OP_breg7 is the contents of r7 but I don't understand the "+8". I 
thought that this expression mean to add 8 to the value in register 7 
but in this case, the expression should be DW_OP_breg7 8 (without "+") 
according to examples of location description in user guide.
