             Bug #: 52695
           Summary: libitm/config/x86/cacheline.h: '__m64' does not name a
                    type
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libitm
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: ncahill_alt@yahoo.com


While building gcc 4.7.0, libitm fails with this error:

In file included from ../../../gcc-4.7.0/libitm/libitm_i.h:85:0,
                 from ../../../gcc-4.7.0/libitm/aatree.cc:28:
../../../gcc-4.7.0/libitm/config/x86/cacheline.h:55:3: error: '__m64' does not
name a type

A possible fix is to add #include <x86intrin.h> 
to cacheline.h, which seems to be the desired intent.

This was built with gcc 4.6.2, from the gcc-4.7.0.tar.bz2 as released on
ftp.gnu.org.  The error occured right at the end, after the bootstrap process
was successful.

Thank you.
Neil.
