HP aC++/HP C A.06.20 Programmer's Guide

Usage:
-Bextern=symbol[,symbol...]
The named symbols, or all symbols if no list is provided, are assigned the default export
class. Use of list form overrides the default binding of locally defined symbols.
-Bextern:filename
The file indicated by filename is expected to contain a list of symbols, separated by
spaces or newlines. These symbols are assigned the default export class.
-Bhidden
-Bhidden
The specified symbols, or all symbols if no symbols are specified, are assigned the
hidden export class. The hidden export class is similar to the protected export class. In
addition, hidden symbols will not be exported outside the current load module. The
linker may eliminate them from a shared library, but in an executable, they remain
accessible to the debugger unless +Oprocelim is also specified.
When used with no symbol list, -Bhidden implies -Wl,-aarchive_shared, causing
the linker to prefer an archive library over a shared library if one is available. This can
be overridden by following the -Bhidden option with a subsequent -Wl,-a option.
Usage:
-Bhidden=symbol[,symbol...]
The named symbols, or all symbols if no symbols are specified, are assigned the hidden
export class.
-Bhidden:filename
The file indicated by filename is expected to contain a list of symbols separated by
spaces or newlines. These symbols are assigned the hidden export class.
-Bhidden_def
-Bhidden_def
This option is the same as -Bhidden, but only locally defined (non-tentative) symbols,
without __declspec(dllexport), are assigned the hidden export class.
-Bprotected
-Bprotected[=symbol[,symbol...]]
The specified symbols, or all symbols if no symbols are specified, are assigned the
protected export class. That means these symbols will not be preempted by symbols
from other load modules, so the compiler may bypass the linkage table for both code
and data references and bind them to locally defined code and data symbols.
