In r14-5118-gc5db4d8ba5f3de I added a mechanism to automatically add
documentation URLs to quoted strings in diagnostics.
In r14-6920-g9e49746da303b8 I added a mechanism to generate URLs for
mentions of command-line options in quoted strings in diagnostics.
This patch does a similar thing for attributes. It adds a new Python 3
script to scrape the generated HTML looking for documentation of
attributes, and uses this to (re)generate a new gcc/attr-urls.def file.
Running "make regenerate-attr-urls" after rebuilding the HTML docs will
regenerate gcc/attr-urls.def in the source directory.
The patch uses this to optionally add doc URLs for attributes in any
diagnostic emitted during the lifetime of a auto_urlify_attributes
instance, and adds such instances everywhere that a diagnostic refers
to a diagnostic within quotes (based on grepping the source tree
for references to attributes in strings and in code).
For example, given:
$ ./xgcc -B. -S ../../src/gcc/testsuite/gcc.dg/attr-access-2.c
../../src/gcc/testsuite/gcc.dg/attr-access-2.c:14:16: warning:
attribute ‘access(read_write, 2, 3)’ positional argument 2 conflicts
with previous designation by argument 1 [-Wattributes]
with this patch the quoted text `access(read_write, 2, 3)'
automatically gains the URL for our docs for "access":
https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html#index-access-function-attribute
in a sufficiently modern terminal.
Two points I'm not sure about:
- like r14-6920-g9e49746da303b8 this avoids the Makefile target
depending on the generated HTML, since a missing URL is a minor
problem, whereas requiring all users to build HTML docs seems more
involved. Doing so also avoids Python 3 as a build requirement for
everyone, but instead just for developers addding attributes.
Like the options, we could add a CI test for this. Is this the right
approach?
- the patch currently gathers target-specific attributes, but doesn't
select the appropriate one; it just picks the first one it sees. For
example, the function attribute "interrupt" has 19 URLs within our docs:
one common, and 18 target-specific ones. I'm not sure what the best
approach here is; perhaps some kind of new target hook for identifying
target-specific documentation?
Thoughts?
