MULTILIBS
®
The standard library function exit calls the weak function _exit prior to returning.
The standard library functions for signals, signal and raise, are implemented as
weak functions which always fail.
The standard library functions for locales, setlocale and localeconv, are
implemented as weak functions which do nothing.
The standard library function for accessing environment variables, getenv, is
implemented as a weak function which always returns NULL.
2.5.1
Macros are provided for many commonly used attributes in order to enhance user code
readability.
2.5.2
System code may need to translate between virtual and physical addresses, as well as
between kernel segment addresses. Macros are provided to make these translations
easier and to determine the segment an address is in.
2.6.1
With multilibs, target libraries are built multiple times with a permutated set of options.
Multilibs are the resulting set of target libraries that are built with these options. When
the compiler shell is called to compile and link an application, the shell chooses the
version of the target library that has been built with the same options.

Evaluates to 1 if the address is a kernel segment virtual address,
zero otherwise.
Evaluate to 1 if the address is a KSEG0 virtual address, zero
otherwise.
Evaluate to 1 if the address is a KSEG1 virtual address, zero
otherwise.
Evaluate to 1 if the address is either a KSEG0 or a KSEG1 virtual
address, zero otherwise.
