Compiling and linking
Compiling with the f90 command
Chapter 262
The file indicated by filename contains a list of symbols, separated by spaces
or newlines. These symbols are assigned the hidden export class.
-Bprotected [=symbol [,symbol...]]
The named symbols, or all symbols if no symbols are specified, are assigned
the protected export class. This 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, -Bprotected implies -W1,
-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
-Bprotected option with a subsequent -W1,-a option.
-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
Marks only data symbols as having the protected export class.
-Bprotected_def
This is the same as -Bprotected, but only locally-defined (non-tentative)
symbols are assigned the protected export class.
-Bsymbolic
All symbols are assigned the protected export class. This is equivalent to
-Bprotected with no symbol list.
Using optimization options
The options described in this section allow you to control the different optimizations that the
compiler can apply to your program. These options fall into two categories:
• Options that control classes of optimization (for example, optimizations that affect code
size)
• Options that control specific optimizations (for example, inlining)
