-qpic Option
Syntax
-qpic[=suboptions]
The -qpic compiler option generates Position Independent Code (PIC) that can be
used in shared libraries.
Arguments
small | large
The small suboption tells the compiler to assume that the size of
the Table Of Contents be at most, 64K. The large suboption allows
the size of the Table Of Contents to be larger than 64K. This
suboption allows more addresses to be stored in the Table Of
Contents. However, it does generate code that is usually larger
than that generated by the small suboption.
-qpic=small is the default.
Specifying -qpic=large has the same effect as passing -bbigtoc to
the ld command.
