1 4.3 Assembler Internal Sections
1 ===============================
1 
1 These sections are meant only for the internal use of 'as'.  They have
1 no meaning at run-time.  You do not really need to know about these
1 sections for most purposes; but they can be mentioned in 'as' warning
1 messages, so it might be helpful to have an idea of their meanings to
1 'as'.  These sections are used to permit the value of every expression
1 in your assembly language program to be a section-relative address.

1 expr section
1      The assembler stores complex expression internally as combinations
1      of symbols.  When it needs to represent an expression as a symbol,
1      it puts it in the expr section.
