            Bug ID: 72757
           Summary: atomic test don't run with RUNTESTFLAGS=atomic.exp
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org
          Reporter: msebor at gcc dot gnu.org
  Target Milestone: ---

The Testing section of the GCC manual (https://gcc.gnu.org/install/test.html)
shows examples of setting the RUNTESTFLAGS variable to one of the .exp files in
the GCC test suite invoke a subset of GCC tests.  This works fine for many .exp
files but not for atomic.exp.  None of the C atomic tests run when make is
invoked with RUNTESTFLAGS=atomic.exp:

$ nice make -C /build/gcc-trunk-svn/gcc check-c RUNTESTFLAGS='atomic.exp'
make: Entering directory '/build/gcc-trunk-svn/gcc'
rm -rf testsuite/gcc-parallel

srcdir=`cd /src/gcc-svn/gcc; ${PWDCMD-pwd}` ; export srcdir ; \
if [ -n "" ] \
   && [ -n "$GCC_RUNTEST_PARALLELIZE_DIR" ] \
   && [ -f testsuite/gcc-parallel/finished ]; then \
  rm -rf testsuite/gcc; \
else \
  cd testsuite/gcc; \
  rm -f tmp-site.exp; \
  sed '/set tmpdir/ s|testsuite$|testsuite/gcc|' \
        < ../../site.exp > tmp-site.exp; \

  EXPECT=`if [ -f ${rootme}/../expect/expect ] ; then echo
${rootme}/../expect/expect ; else echo expect ; fi` ; export EXPECT ; \
  if [ -f ${rootme}/../expect/expect ] ; then  \
    TCL_LIBRARY=`cd .. ; cd ${srcdir}/../tcl/library ; ${PWDCMD-pwd}` ; \
    export TCL_LIBRARY ; \
  fi ; \
  `if [ -f ${srcdir}/../dejagnu/runtest ] ; then echo
${srcdir}/../dejagnu/runtest ; else echo runtest; fi` --tool gcc atomic.exp; \
  if [ -n "$GCC_RUNTEST_PARALLELIZE_DIR" ] ; then \
    touch ${rootme}/testsuite/gcc-parallel/finished; \
  fi ; \
fi )
