Seen on sparc64 in hdtoa.c:341 since sparc64 is one of the platforms
that has 128-bit long double and defines struct ieee_ext.ext_frach:48
based on uint64_t, which is a GCC extension. Plain C99 only allows
_Bool, signed int and unsigned int as base type for bit-fields.
These types are explicitly allowed by GCC.
I'm not sure which of the flags -g and -p should be stronger. That is,
if both -g and -p are given, should 'unsigned char' be allowed as a
bit-field type since -g would allow it, or should it be warned about
since -p warns about it? For now, continue to warn about these.
The whole purpose of this test is to try the message about invalid
bit-field types in GCC mode. Therefore, use the default lint1-flags
that include -g.
The build failed with this error message:
x86_64--netbsd-install: the last argument (/.../emit.ln) must
name an existing directory
The cause for this message was that ${DESTDIR}/.../emit.ln has
${DESTDIR}/.../emit.c as implicit target, which is kind of correct but
unintended in this case. Because of this, the command 'install' was run
like this:
install ${NETBSDSRCDIR}/.../emit.ln ${DESTDIR}/.../emit.c \
${DESTDIR}/.../emit.ln
Even though the new test is quite large, it didn't find any bugs in the
code. The only thing I'm unsure about is why static functions are
exported as well, since they are supposed to be local to the translation
unit.
The description of the tests is not going to be added anytime soon, as
that would either create redundancy or additional run-time cost.
Parsing and evaluating unit-tests/Makefile is already O(n^2) with regard
to the number of tests, and there are quite a few tests. Therefore don't
add any overhead for now.
The list of available letters for the command line options gets shorter
and shorter. Most of the interesting letters are already used for some
warning categories. Curiously, -A, -W and -E were all still available.
The option -A nicely matches the intention of the option, which is to
allow a certain set of language features. To keep the option available
for further extensions, define -Ac11 as the currently only valid option
of that kind. This allows straight-forward extension for C17 and future
language standards, as well as independent feature-sets. The options -W
and -E may someday complement the -A option, using the allow/warn/error
categories.
