32# standard ROOTBIN and ROOTBIN64 rules defined in ../Makefile.cmd are used.
33# The new rules here are included to allow for easier backporting. Making
34# the appropriate updates in ./Makefile.var, will allow the SGS components
35# to be installed in /usr/ccs/bin rather than the current /usr/bin.

45# Linting the Linker Libraries
46#
47#  Several of the linker's libraries are, in whole or in part, built in two
48#  passes, once as Elf32 and once as Elf64 (i.e. with -D_ELF64 defined).  Lint
49#  needs to be able to do both passes, but combining the two is problematic for
50#  the 2nd pass of lint, as it sees many interfaces as being defined both ways
51#  and considers them to be incompatible.  The targets defined here allow for
52#  both passes to live independently.  This means that both the lint.out, and
53#  the lint library itself get generated separately, to different output files.
54#  The lint.out's get combined into a single lint.out report, and the lint
55#  libraries get generated with a 32/64 suffix.  The dependents on these lint
56#  libraries, then, choose which version they need to use.  Substitutions can
57#  be made automatically if the macro's defined in ./Makefile.com are used to
58#  specify the dependency, for those libs that need them.
59#
60# Don't
61#
62#  Don't use the /*LINTLIBRARY*/ directive in linker libraries, this disables
63#  some important checks, including the ability to test format strings from the
64#  msg.h files.
65#
66#  Don't use the `-x' option to lint when linting linker libraries.  This masks
67#  all the dead wood in our own header files.  Instead, there has been added to
68#  the relevant common directories a file called `lintsup.c' which is used to
69#  mask out the headers that we aren't interested in.  This method is used for
70#  libraries, like libld, which have their own header files, but is irrelevant
71#  to libraries like libldstab which exports no interface of it's own.
72#
73#  The `lintsup.c' file can also be used, in some cases, to mask out other
74#  issues that lint won't otherwise shut up about.
75#
76# Other Lint Options
77#
78#  `-m' has been added to the LINTFLAGS.  Warnings about globals that could be
79#  static are irrelevant as we use mapfiles to scope down unnecessary globals.
80#
81#  `-u' is used in the LINTFLAGS for libraries, otherwise lint tends to be very
82#  noisy.
83#
84#  `-x' is avoided for libraries, but is used for executables because all we
85#  care about is that what we use is defined, not about declarations in public
86#  headers that we don't use.
