             Bug #: 55594

           Summary: [4.8 Regression] -Wa,-nH incorrectly added to compile

                    line of all targets

    Classification: Unclassified

           Product: gcc

           Version: 4.8.0

            Status: UNCONFIRMED

          Severity: normal

          Priority: P3

         Component: libstdc++

        AssignedTo: unassig...@gcc.gnu.org

        ReportedBy: d...@gcc.gnu.org





On 2012-09-12, a patch was added to libstdc++ to instruct the Sun assembler to

clear hardware capabilities with -nH command line option. However, the test in

configure is not limited to Sun Solaris and adds the option to all systems for

which the assembler accepts a "-nH" option, regardless of the meaning of the

option. This produces incorrect results on other systems.
