42# Linting the Linker Libraries
43#
44#  Several of the linker's libraries are, in whole or in part, built in two
45#  passes, once as Elf32 and once as Elf64 (i.e. with -D_ELF64 defined).  Lint
46#  needs to be able to do both passes, but combining the two is problematic for
47#  the 2nd pass of lint, as it sees many interfaces as being defined both ways
48#  and considers them to be incompatible.  The targets defined here allow for
49#  both passes to live independently.  This means that both the lint.out, and
50#  the lint library itself get generated separately, to different output files.
51#  The lint.out's get combined into a single lint.out report, and the lint
52#  libraries get generated with a 32/64 suffix.  The dependents on these lint
53#  libraries, then, choose which version they need to use.  Substitutions can
54#  be made automatically if the macro's defined in ./Makefile.com are used to
55#  specify the dependency, for those libs that need them.
56#
57# Don't
58#
59#  Don't use the /*LINTLIBRARY*/ directive in linker libraries, this disables
60#  some important checks, including the ability to test format strings from the
61#  msg.h files.
62#
63#  Don't use the `-x' option to lint when linting linker libraries.  This masks
64#  all the dead wood in our own header files.  Instead, there has been added to
65#  the relevant common directories a file called `lintsup.c' which is used to
66#  mask out the headers that we aren't interested in.  This method is used for
67#  libraries, like libld, which have their own header files, but is irrelevant
68#  to libraries like libldstab which exports no interface of it's own.
69#
70#  The `lintsup.c' file can also be used, in some cases, to mask out other
71#  issues that lint won't otherwise shut up about.
72#
73# Other Lint Options
74#
75#  `-m' has been added to the LINTFLAGS.  Warnings about globals that could be
76#  static are irrelevant as we use mapfiles to scope down unnecessary globals.
77#
78#  `-u' is used in the LINTFLAGS for libraries, otherwise lint tends to be very
79#  noisy.
80#
81#  `-x' is avoided for libraries, but is used for executables because all we
82#  care about is that what we use is defined, not about declarations in public
83#  headers that we don't use.

157# A couple of macros used in the SGSLINTOUT rule below
158#
159#	LINT_HDR - Use sgs/tools/lint_hdr.pl to generate lint output headers
160#	LINT_TEE - Use tee to write output to stdout and also capture it
161#		in the SGSLINT output file.
162#
163# An additional complexity: We produce headers for all the lint
164# output so that we can tell what came from where when we look
165# at the resulting file. We also cat these headers to stdout so that
166# the user of make will see them. However, we don't want the headers
167# to go to stdout if there is only one of LINTOUT32 and LINTOUT64. To
168# the interactive user, the headers are only interesting as a way to
169# separate the two ELF classes. We only bother with this for the
170# non-DYNLIB and non-RTLD case, because at the current time, both of these
171# cases always have both 32 and 64-bit ELFCLASS support.
