Lint # needs to be able to do both passes, but combining the two is problematic for # the 2nd pass of lint, as it sees many interfaces as being defined both ways # and considers them to be incompatible. The targets defined here allow for # both passes to live independently. This means that both the lint.out, and # the lint library itself get generated separately, to different output files. # The lint.out's get combined into a single lint.out report, and the lint # libraries get generated with a 32/64 suffix. The dependents on these lint # libraries, then, choose which version they need to use. Substitutions can # be made automatically if the macro's defined in ./Makefile.com are used to # specify the dependency, for those libs that need them. # # Don't # # Don't use the /*LINTLIBRARY*/ directive in linker libraries, this disables # some important checks, including the ability to test format strings from the # msg.h files. # # Don't use the `-x' option to lint when linting linker libraries. This masks # all the dead wood in our own header files. Instead, there has been added to # the relevant common directories a file called `lintsup.c' which is used to # mask out the headers that we aren't interested in. This method is used for # libraries, like libld, which have their own header files, but is irrelevant # to libraries like libldstab which exports no interface of it's own. # # The `lintsup.c' file can also be used, in some cases, to mask out other # issues that lint won't otherwise shut up about. # # Other Lint Options # # `-m' has been added to the LINTFLAGS. Warnings about globals that could be # static are irrelevant as we use mapfiles to scope down unnecessary globals. # # `-u' is used in the LINTFLAGS for libraries, otherwise lint tends to be very # noisy. # # `-x' is avoided for libraries, but is used for executables because all we # care about is that what we use is defined, not about declarations in public # headers that we don't use. # # Relevant variables: # # */Makefile.com # SRCS= ../common/llib-l # LINTSRCS= # LDLIBS= ...
