When running the gcc testsuite for target=powerpc-eabisim, a number of test
cases fail intermittently -- they pass or fail randomly. It appears that the
simulator is not returning the correct exit code.
When run using gdb, all of the test cases pass consistently.
Randomly failing test cases:
gcc.c-torture/execute/builtins/fprintf.c
gcc.c-torture/execute/builtins/fputs.c
gcc.c-torture/execute/builtins/printf.c
gcc.c-torture/execute/20020406-1.c
gcc.c-torture/execute/fprintf-1.c
gcc.c-torture/execute/fprintf-chk-1.c
gcc.c-torture/execute/printf-chk-1.c
gcc.c-torture/execute/va-arg-21.c
gcc.c-torture/execute/vfprintf-1.c
gcc.c-torture/execute/vfprintf-chk-1.c
gcc.dg/packed-array.c
gcc.dg/matrix/matrix-2.c
To reproduce: build gcc and sim using combined method:
http://www.gnu.org/software/gcc/simtest-howto.html. configure params:
--target=powerpc-eabisim --prefix=/home/eager/Xilinx/ppc/combined-plain/install
--enable-languages=c --disable-nls --disable-build-warnings --disable-libssp
In build, run 'make check-gcc RUNTESTFLAGS="execute.exp -v
--target_board=powerpc-sim"' or to run one case: 'make check-gcc
RUNTESTFLAGS="execute.exp=va-arg-21.c -v --target_board=powerpc-sim"'
