Bug ID: 89142
Summary: Allow poisoning identifier from the command line
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: preprocessor
Assignee: unassigned at gcc dot gnu.org
Reporter: Simon.Richter at hogyros dot de
Target Milestone: ---
I'm currently refactoring a program that uses a preprocessor symbol in various
places, and I'd like to generate errors for all uses.
There is no common header file in which I could place a `#pragma gcc poison`
directive, but I can modify the CPPFLAGS globally.
It would be nice to have a way to add poisoned preprocessor symbols from the
command line.
