           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

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

Just use RUNTESTFLAGS='--target_board=unix\{-m32,\}'
which is parallelized.

Is there a way to paralelize --target_board 'unix{-m32,}'?

I tried RUNTESTFLAGS="--target_board 'unix\{-m32,\}'". It doesn't
look like parallelized:

[hjl@gnu-32 gcc]$ ls build-x86_64-linux/gcc/testsuite
g++  gcc  gfortran  objc
[hjl@gnu-32 gcc]$

There are

$(lang_checks_parallelized): check-% : site.exp
        @if [ -z "$(filter-out --target_board=%, $(RUNTESTFLAGS))" ] \
            && [ "$(filter -j, $(MFLAGS))" = "-j" ]; then \

If there is a --target_board=, we don't parallelize.

I have to use exactly:

RUNTESTFLAGS=--target_board='unix{-m32,}'

I changed to

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

and it finished in 34 minutes.
