The urlifier does "know" the lang_mask, so I had a go at using that.
Here's an updated version of the patch kit.
In this one, rather than just parsing 'gcc/Option-Index.html',
regenerate-opt-urls.py now parses all of:
'gcc/Option-Index.html' for generic options
'gdc/Option-Index.html' with language='D'
'gfortran/Option-Index.html' with language='Fortran'
As before, it generates .opt.urls files, but now they can contain
multiple directives: as well as the UrlSuffix directive, each
language now has a LangUrlSuffix_NAME_OF_LANG directive, such as
LangUrlSuffix_D
and
LangUrlSuffix_Fortran
I initially tried to have a single LangUrlSuffix(LANG, URL) directive,
but having them as a family of separate directives turned out to be much
easier to handle from the .awk scripts.
Hence the optionlist contains options for all configured targets
and for all frontends, and can contain multiple URLs. For example,
Walloca has:
Walloca UrlSuffix(gcc/Warning-Options.html#index-Walloca) LangUrlSuffix_D(gdc/Warnings.html#index-Walloca)
The options-urls.cc generated by options-urls-cc-gen.awk previously
contained a big array of string literals. To handle lang-specific
options, options-urls.cc now contains a generated switch statement
of the form:
const char *
get_opt_url_suffix (int option_index, unsigned lang_mask)
{
switch (option_index)
{
[...snip...]
case OPT_Walloca:
if (lang_mask & CL_D)
return "gdc/Warnings.html#index-Walloca";
return "gcc/Warning-Options.html#index-Walloca";
[...snip...]
return nullptr;
}
I tested this via compiling .c and .d files with gcc and gdc to generate
a -Walloca warning. Each compiler emitted the "correct" documentation
URL for -Walloca, in that gcc's URL pointed at the generic documentation,
and gdc's at the D-specific documentation. There is also automated
selftest coverage for lang-specific URLs (in
selftest::test_get_option_url_suffix).
As before, with:
warning: ‘#pragma pack’ has no effect with ‘-fpack-struct’ - ignored [-Wpragmas]
it successfully provides the user with three URLs (in a suitable
terminal): the documentation of the pragma, the -fpack-struct option,
and the -Wpragmas warning, respectively.
Successfully bootstrapped & regrtested on x86_64-pc-linux-gnu, with all
languages enabled, using gawk-5.0.1
I also smoke-tested the build with the patch on a minimal configuration
with just --enable-languages=c,c++ (and, in particular, with D *not*
enabled), and it built successfully.
How is this looking for trunk?
Thanks
Dave
