Linker Tasks

Using 64-bit Mode Linker Options

only load those modules from an archive library that is needed. The mode you select, either by default or explicitly, remains on until you change it.

+noforceload is the default on both 32-bit and 64-bit modes.

In the following example, main() references foo(), which is a module in mylib.a. foo() doesn’t reference any other module in mylib.a and libc.a. If mylib.a contains foo.o and bar.o, then only foo.o is linked in.

ld crt0.o main.o +vtype libraries mylib.a -lc

...

Selecting liba.a[foo.o] to resolve foo

ld crt0.o main.o +forceload mylib.a -lc +vtype libraries

...

Selecting liba.a[foo.o] to forcibly load Selecting liba.a[bar.o] to forcibly load

Flagging Unsatisfied Symbols with +[no]allowunsats

Use the +allowunsats option to instruct the linker to not flag unsatisfied symbols at link time. This is the default for relocatable (-r) and shared library builds (-b), and is the default behavior in 32-bit mode.

Use the +noallowunsat option to instruct the linker to flag as an error any unsatisfied symbol in the resulting output file. The linker still creates a.out, but the file does not have any execute permission bits set. This is the default for program files (same behavior as in 32-bit mode).

For example, where main() references functions foo() and bar(). bar() resides in libbar.sl. foo() resides in libfoo.sl

ld main.o +allowunsats -L. -lbar -lc

ld: (warning) Unsatisfied symbol “foo”. 1 warning.

+allowunsats still causes the linker to emit a warning message and output a.out. If you do not specify the option and the linker finds an unsatisfied symbol, the linker emits an error message and an unexecutable a.out only if linking with +compat set.

ld main.o -L. -lbar -lc

ld: Unsatisfied symbol “foo”. 1 error.
