Bug #: 13548
Summary: #pragma clang diagnostic push ignores garbage at end
of line without warning
Product: clang
Version: 3.1
Platform: Macintosh
OS/Version: MacOS X
Status: NEW
Severity: enhancement
Priority: P
Component: Frontend
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Classification: Unclassified
I blithely wrote the following code:
#pragma clang diagnostic push ignored "-Wdeprecated-declarations"
Which should not be expected to work, nor is it documented to. Owing to a
mental scotoma I could not comprehend why deprecated-declaration warning
continued to be issued.
As it happens you can put nigh anything at the end of the line and the compiler
will silently ignore it.
If the compiler had warned about the garbage, it would have saved me some
mental anguish. Perhaps we need to add -Wextra-stuff-at-end-of-pragma. Or
perhaps we don't need to make that one optional.
