Bug #: 53554
Summary: -Q --help=<class> gives inaccurate target-specific
information
Classification: Unclassified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: driver
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: philomath868@gmail.com
some code that sets target-specific defaults isn't run when using the
--help=<class> option, this causes some incorrect information to be displayed.
for example, -fomit-frame-pointer shows as disabled on a x86_64 system with
optimization selected, mfpmath=387 is shown on such a system (where
-mfpmath=sse is the default), and mmx seems to be disabled on a system which
supports it (even when -march=native is specified).
see http://gcc.gnu.org/ml/gcc-help/2012-06/msg00006.html .
