Bug ID: 70922
Summary: -Wparentheses warning should not complain about
if-else from macro expansion
Product: gcc
Version: unknown
Status: UNCONFIRMED
Keywords: diagnostic
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: ktkachov at gcc dot gnu.org
Target Milestone: ---
As described here:
https://sourceware.org/ml/gdb-patches/2016-04/msg00656.html
I upgraded my host compiler to GCC 6.1 and started getting some -Werror build
failures in gdb due to -Wparentheses, but the offending if-else structure came
from a macro expansion where the intended structure was obvious.
It's been suggested that the GCC warning is unhelpful there and a regression:
https://sourceware.org/ml/gdb-patches/2016-05/msg00003.html
Should -Wparentheses not trigger on such if-else structure coming from a macro
expansion?
