Bug ID: 100121
Summary: RFE: plugin support for -Wformat via
__attribute__((format()))
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dmalcolm at gcc dot gnu.org
CC: msebor at gcc dot gnu.org
Target Milestone: ---
https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html#index-format-function-attribute
documents the various "archetypes" supported by
__attribute__ ((format (ARCHETYPE, M, N)));
These are all just built-in to the compiler.
It would be nice to allow users to add their own, via plugins.
Consider e.g.
https://gcc-python-plugin.readthedocs.io/en/latest/cpychecker.html#format-string-checking
for which I had to effectively implement my own version of -Wformat, rather
than being able to reuse gcc's implementation.
