Hi, Test case bswap64-4.c suffers the issue as its comments:
/* On some versions of dejagnu this test will fail when biarch testing with RUNTESTFLAGS="--target_board=unix '{-m64,-m32}'" due to -m32 being added on the command line after the dg-options -mpowerpc64. common/config/rs6000/rs6000-common.c: rs6000_handle_option disables -mpowerpc64 for -m32. */ As tested, on test machine with dejaGnu 1.6.2, the compilation option order looks like: -m32 ... -mpowerpc64, option -mpowerpc64 still takes effect; While on test machine with dejaGnu 1.5.1, the option order looks like: -mpowerpc64 ... -m32, option -mpowerpc64 is disabled by -m32, then the case fails. This fix leverages the new effective target has_arch_ppc64 and places dg-options before dg-require-effective-target (it makes dg-options to be used for has_arch_ppc64 checking), on machine with dejaGnu 1.6.2, the checking succeeds and the case passes; while on machine with dejaGnu 1.5.1, the checking fails then the case is marked as unsupported. Tested on powerpc64-linux-gnu P7 and P8, and powerpc64le-linux-gnu P9 and P10. I'll push this soon if no objections.
