The current scheme to identify which module a translation unit is built in depends on defining multiple macros IS_IN_* and also defining NOT_IN_libc if we're building a non-libc module. In addition, there is an IN_LIB macro that does effectively the same thing, but for different modules (notably the systemtap probes). This macro scheme unifies both ideas to use just one macro IN_MODULE and assign it a value depending on the module it is being built into. If the module is not defined, it defaults to MODULE_libc. Patches that follow will replace uses of IS_IN_* variables with the IS_IN() macro. libc-symbols.h has been converted already to give an example of how such a transition will look. Verified that there are no relevant binary changes. One source change that will crop up repeatedly is that of nscd_stat, since it uses the build timestamp as a constant in its logic. * Makeconfig (in-module): Get value of libof set for the translation unit. (CPPFLAGS): Use $(in-module). * Makerules: Don't suffix routine names for nonlib. * include/libc-modules.h: New file. * include/libc-symbols.h: Include libc-modules.h (IS_IN): New macro to replace IS_IN_* macros. * elf/Makefile: Set libof-* for each routine. * elf/rtld-Rules: Likewise. * extra-modules.mk: Likewise. * iconv/Makefile: Likewise. * iconvdata/Makefile: Likewise. * locale/Makefile: Likewise. * malloc/Makefile: Likewise. * nss/Makefile: Likewise. * sysdeps/gnu/Makefile: Likewise. * sysdeps/ieee754/ldbl-opt/Makefile: Likewise. * sysdeps/unix/sysv/linux/Makefile: Likewise. * sysdeps/s390/s390-64/Makefile: Likewise. * nscd/Makefile: Set libof-* for each routine. Set CFLAGS and CPPFLAGS for nscd instead of nonlib.
