HP C/aC++ for PA-RISC Software manual Bhiddendef, Bprotecteddata, Bprotecteddef

-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, -Bhiddenimplies -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 -Bhiddenoption with a subsequent -Wl,-aoption.

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.

When used with no symbol list, -Bprotectedimplies -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 -Bprotectedoption with a subsequent -Wl,-aoption.

Usage:

-Bprotected:filename

The file indicated by filename contains a list of symbols, separated by spaces or newlines. These symbols are assigned the protected export class.

-Bprotected_data

-Bprotected_data

The -Bprotected_dataoption marks only data symbols as having the protected export class.

-Bprotected_def

-Bprotected_def
