Bug ID: 103141
Summary: #pragma GCC diagnostic ignored
"-Wno-deprecated-declarations" doesn't work
Product: gcc
Version: 7.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: preprocessor
Assignee: unassigned at gcc dot gnu.org
Reporter: noah at revrobotics dot com
Target Milestone: ---
When I have a header file that includes the line #pragma GCC diagnostic ignored
"-Wno-deprecated-declarations", this warning is printed:
warning: unknown option after '#pragma GCC diagnostic' kind [-Wpragmas]
#pragma GCC diagnostic ignored "-Wno-deprecated-declarations"
When I replace no-deprecated-declarations with unused-result, that works.
It appears that GCC 11.2 still has this issue: https://godbolt.org/z/nYsPM9PT7
