The debug output contained too many newlines.
The buffer functions were built into lint2 even though they weren't
used.
Enable the query for invisible characters in string literals, to make
sure that a newline in a string literal does not trigger that query.
The plain char literals are needed for checking printf/scanf format
strings; lint has no similar check for wide strings. These format
strings are checked by modern compilers, making this check less
relevant.
An integer constant that is signed in traditional C but unsigned since
C90 is an edge case that should not clutter the main code of determining
the resulting type of the constant.
The code for lexing an integer constant doesn't implement the C99 rules
yet, which convert a constant to the 'long long' types if the 'long'
types don't suffice.
It was confusing to have two kinds of "symbol type" (s_type and s_symt),
so rename all related identifiers to be more distinctive.
No functional change.
These were leftovers from splitting large functions into smaller
functions, to ensure that variables were not unintentionally reassigned.
Those refactorings are finished, and the extra help from the compiler is
no longer necessary.
No binary change.
This allows to configure lint flags in mk.conf globally for a whole
NetBSD build. Previously, this would have made the build fail due to
missing .ln files.
The previous use case of rerunning lint with or without queries is easy
enough to achieve by doing a 'make clean', in the same way as for lint
warnings.
logic on kernel options so long as those options are not defflag'd or
defparam'd. This works because such options are automatally added to the
IDENT var in the kernel Makefile as a preprocessor define, and the Makefile
can then do an operation like:
.if !empty(IDENT:M-DSOMECOOLCPUOPTION)
CFLAGS+= -mcpu=somecoolcpu
.endif
Unfortunately, this precludes making it possible to generate a compile-time
dependency on SOMECOOLCPUOPTION, or having SOMECOOLCPUOPTION imply another
kernel config option using the normal config(1) option dependency function.
Fix this by introducing a new option description keyword: mkflagvar. This
keyword marks an already defflag'd option as wanting a kernel Makefile var
defined if that option is selected in the kernel config file. So:
defflag opt_coolcpu.h SOMECOOLCPUOPTION ANOTHERCOOLCPUOPTION
mkflagvar SOMECOOLCPUOPTION ANOTHERCOOLCPUOPTION
will cause:
KERNEL_OPT_SOMECOOLCPUOPTION="1"
KERNEL_OPT_ANOTHERCOOLCPUOPTION="1"
...to be emitted into the kernel Makefile if those options are, in fact,
selected with "options ..." in the kernel config file, thus allowing for
a compile-time dependency on the option to be generated in addition to
Makefile logic, which now looks like:
.if !empty(KERNEL_OPT_SOMECOOLCPUOPTION)
CFLAGS+= -mcpu=somecoolcpu
.endif
When a cast-expression comes partly from a system header, determine at
the ')' whether the whole cast-expression comes from the system header.
Previously, it was based on the operand, which contradicted the
documentation of tn_sys.
Mainly affects strict bool mode (where expressions from system headers
are handled more leniently), as well as query 9 for parenthesized return
expressions.
Discovered upon manual inspection, as calling expr_alloc_tnode should
never be necessary when creating an expression node with operands;
there's build_op for that purpose.

Both GCC 11 and Clang 8 accept member-designators that are not
identifiers but designator sequences, such as in 'offsetof(struct stat,
st_atim.tv_sec)', so make lint accept them as well.
