New Features for 64-bit Mode Linking

-dynamic

Forces the linker to create a shared executable. The linker looks for shared libraries first and then archived libraries. This option is on by default when you compile in 64-bit mode.

-noshared

Forces the linker to create a fully bound archive program.

-k filename

Allows you to control the mapping of input section in the object file to segments in the output file.

+[no]allowunsats

Instructs the linker how to report errors for output files with unsatisfied symbols.

+compat

Instruct the linker to use 32-bit mode linking and dynamic loading behaviors.

+[no]forceload

Enables/disables forced loading of all the object files from archive libraries.^a

+hideallsymbols

Hides all symbols from being exported.^a

+nodefaultmap

Instructs the linker not to load the default mapfile. See the -k option.^a

+noenvvar

Instructs the dynamic loader not to look at the LD_LIBRARY_PATH and SHLIB_PATH environment variables at runtime.^a

+std

Instructs the linker to use SVR4 compatible linking and loading behaviors. Default for 64-bit mode.^a

+stripunwind

Instructs the linker not to output the unwind table.

+vtype type

Produces verbose output about selected link operations.^a

a. The linker accepts but ignores this option in 32-bit mode. It creates an executable (a.out).
