- Subject: Question about Offsets
This question is regarding adding offsets into a user-defined section into gcc.
Letâs say I have a section called âmy_sectionâ and I want the section to have some sub-sections (e.g. a string table). One of the fields in my section is the offset to the next header. How do I represent this in GCC? I think I have to do it in RTL expressions (RTX).
Here is an example of what I am trying to do (please note that what I have below is a semi-pseudo code).
# The next 5 lines are headers
.ascii âMy Section Magic Headerâ
.int STRING_TABLE_LABEL â START_LABEL â====== HOW TO DO THIS? I WOULD LIKE THE LINKER TO THEN CONVERT IT TO A NUMBER.
.int 10 <SIZE OF STRING TABLE>
â # Here I have other data which could be of variable length
