Bug #: 52347
Summary: -Wno-tabs -Wall -Wno-tabs still warns about tabs
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Keywords: diagnostic
Severity: normal
Priority: P3
Component: fortran
AssignedTo: [email protected]
ReportedBy: [email protected]
With mosts flags, a flag which is implied by another flag can be overridden by
the specific flag. For instance -f(no-)protect-parens overriddes the settings
of -O0 (protected) or -Ofast (unprotected parentheses).
However, for tab warnings -Wno-tabs cannot be used to turn off the warning,
enabled by -Wall.
I wouldn't be surprised if that also holds for other warnings, enabled by -Wall
or -Wextra.
