           Summary: make -j 12 RUNTESTFLAGS="--target_board 'unix{-m32,}'"
                    isn't parallelized
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
        AssignedTo: unassigned@gcc.gnu.org

On Linux/x86-64 with 12 cores,

make -j 12 check RUNTESTFLAGS="--target_board 'unix{-m32,}'"

takes 1 hour and 44 minutes while

make -j 12 check

only takes 20 minutes. I got

[hjl@gnu-34 bld]$ ls gcc/testsuite
g++  gcc  gfortran  objc
[hjl@gnu-34 bld]$ 

vs

[hjl@gnu-34 bld]$ ls gcc/testsuite
g++   g++2  gcc1  gcc3  gcc5  gfortran   gfortran2  objc
g++1  gcc   gcc2  gcc4  gcc6  gfortran1  gfortran3  objc1
