/* co-gcc.lnt: This is the seed file for configuring Lint for use with
GCC versions 2.95.3 and later.
Like all compiler options files this file is intended to be used
as follows:
lint co-gcc.lnt source-files-to-be-linted
Some of the information that co-gcc.lnt requires needs to be furnished
with the help of the gcc system itself. The easiest way to generate
this information is to use the makefile co-gcc.mak (supplied with the
Lint distribution) in an invocation of GNU Make; for details, see the
commentary at the top of co-gcc.mak.
*/
-cgnu // Notifies FlexeLint that gcc is being used.
// ===========================
// Preprocessor Configuration:
+fdi // GCC starts its #include search in the directory of the including
// file.
++fln // Allow:
// # digit-sequence " [s-char-sequence] " new-line
// as a synonym for:
// # line digit-sequence " [s-char-sequence] " new-line
// GCC additionally allows flag values to follow the
// s-char-sequence, but currently Lint ignores them.
@INCLUDES@
// Assertion directives (a feature of GCC's preprocessor) have been
// considered obsolete in GCC's documentation since version 3.0, so we do
// not use them here. If support for #assert is needed in the form of a
// lint option, one may use '-a#' like so:
// -a#machine(i386) // #assert's machine(i386) (SVR4 facility).
// File extensions:
// From the GCC man page:
//
// file.cc
// file.cp
// file.cxx
// file.cpp
// file.CPP
// file.c++
// file.C
// C++ source code that must be preprocessed. Note that in .cxx, the
// last two letters must both be literally x. Likewise, .C refers to
// a literal capital C.
//
// We emulate this with:
+cpp(.cc)
+cpp(.cp)
+cpp(.cxx)
+cpp(.cpp)
+cpp(.c++)
// Note the exceptions:
// +cpp(.CPP)
// +cpp(.C)
// These are commented out for the default config because they seem to
// cause trouble more often than not. For starters, it is problematic
// with filesystems that are case-insensitive (which has become common
// even on some POSIX systems).
// =============
// Size Options:
// +fwc // wchar_t might be builtin; if so, uncomment this option. (NOTE:
// // this option needs to be set before a size option is given for
// // wchar_t; see the documentation for -sw# in the Lint manual.)
// size-options.lnt // This .lnt file should be generated (preferrably
// by a program created by invoking GCC with the compile options that
// are used in the compilation of the project to be linted). This
// happens automatically when 'make -f co-gcc.mak' is invoked.
// ===========================================
// +rw and -d options to cope with GNU syntax:
+ppw(ident) // Tolerate #ident
+ppw(warning)
// GCC provides alternative spellings of certain keywords:
+rw(__inline)
-rw_asgn(__inline__,__inline)
-rw_asgn(__header_always_inline,__inline)
-rw_asgn(__header_inline,__inline)
-rw_asgn(__signed__,signed)
-rw_asgn(__signed,signed)
-rw_asgn( __volatile__, volatile )
-rw_asgn( __volatile, volatile )
+rw(restrict)
-rw_asgn(__restrict,restrict)
-rw_asgn(__restrict__,restrict)
++d"__const=const" // gconv.h uses __const rather than const
++d"const=const" // ensure const expands to const.
-rw_asgn( asm, _up_to_brackets )
-rw_asgn( __asm, _up_to_brackets )
-rw_asgn( __asm__, _up_to_brackets )
// This re-definition of the various spellings of the asm keyword enables
// Lint to pass gracefully over expression-statements like:
// __asm __volatile ("fsqrt" : "=t" (__result) : "0" (__x));
// But it may be necessary to suppress certain error messages that are
// triggered by tokens that are part of an assembly declaration or
// statement. For example:
-d"__asm__(p...)=/*lint -e{19}*/ __asm__(p)"
// ...causes Lint to be quiet about the semicolon that follows an
// __asm__() declaration. Note, the -e{N} form of suppression takes
// effect only for the forward-declaration, definition or
// [possibly-compound] statement that immediately follows. Because a
// semicolon is seen as a declaration-terminator, Error 19 will be
// re-enabled immediately after the semicolon in '__asm__(...);'.
// (The elipsis after the macro parameter p allows zero or more commas to
// appear in the operand.)
//
// If you encounter other diagnostics that appear to need suppression in
// or near assembly regions, please let us know!
//
-esym(123,__asm__)
++d"_Static_assert(...)=/*lint -e{19}*/"
-rw_asgn(__alignof__,__alignof)
// "__extension__" is GCC's way of allowing the use of non-standard
// constructs in a strict Standard-conforming mode. We don't currently
// have explicit support for it, but we can use local suppressions. For
// example, we can use -e(160) so that we will not see any Errors about
// GNU statement-expressions wrapped in __extension__().
++d"__extension__=/*lint -e(160) */"
++d"__null=0"
+rw(_to_semi) // needed for the two macros above.
+rw(__typeof__) // activate __typeof__ keyword
-d"__typeof=__typeof__" // an alternative to using __typeof__
-rw(__except) // This MS reserved word is used as an identifier
+rw( __complex__, __real__, __imag__ ) // reserved words that can be ignored.
++d"__builtin_strchr=(char*)" // permits the inline definition ...
++d"__builtin_strpbrk=(char*)" // of these functions to be linted ...
++d"__builtin_strrchr=(char*)" // without drawing a complaint
++d"__builtin_strstr=(char*)" // about the use of a non-standard name
++d"__PRETTY_FUNCTION__=___function___" // lint defines ___function___ internally
++d"__FUNCTION__=___function___" // lint defines ___function___ internally
++d"__func__=___function___" // Some C++ modes suport the implicit __func__
// identifier.
-ident($)
// =========================================================
// Other options supporting GNU C/C++ syntax:
+fld // enables the processing of _L_abel _D_esignators E.g.:
// union { double d; int i; } u = { d: 3.141 };
// =========================================================
// Generally useful suppressions:
-wlib(1) // sets the warning level within library headers to 1
// (no warnings, just syntax errors). Comment out if you
// are actually linting library headers.
-elib(123) // 123 is really a warning, but it's in the "Error" range.
-elib(93) // allow newlines within quoted string arguments to macros
-elib(46) // allow bit fields to have integral types other than
// '_Bool' and 'int'.
-elibsym(628) // Suppress 628 for __builtin symbols.
-esym(528,__huge_val,__nan,__qnan,__qnanf,__snan,__snanf)
// We don't care if we don't reference some GNU functions
-esym(528,__gnu_malloc,__gnu_calloc)
// The following functions exhibit variable return modes.
// That is, they may equally-usefully be called for a value
// as called just for their effects. Accordingly we inhibit
// Warning 534 for these functions.
// Feel free to add to or subtract from this list.
-esym(534,close,creat,fclose,fprintf,fputc)
-esym(534,fputs,fscanf,fseek,fwrite,lseek,memcpy,memmove,memset)
-esym(534,printf,puts,scanf,sprintf,sscanf,strcat,strcpy)
