             Bug #: 52138
           Summary: Operations on complex values are not inlined, even
                    with -O3
    Classification: Unclassified
           Product: gcc
           Version: 4.5.2
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: c
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: gonnet@maths.ox.ac.uk


Irrespective of the optimization level selected, multiplying or dividing two
complex doubles generates a call to __muldc3 or __divdc3 respectively.

Using the "-fcx-limited-range" flag inlines the operations, but then the range
may be limited.

Strangely enough, in the gfortran frontend, complex arithmetic is inlined even
with no optimization (-O0).
