[PATCH] testsuite: Remove unwanted 'dg-do run' from gcc.dg/vect tests
Tests under gcc.dg/vect use check_vect_support_and_set_flags to set
compilation flags as appropriate for the target, but they also set
dg-do-what-default to 'run' or 'compile', depending on the actual
target hardware (or simulator) capabilities.
For instance on arm, we use options to enable Neon, but set
dg-do-what-default to 'run' only if we cam actually execute Neon
instructions.
Therefore, we would always try to link and execute tests containing
'dg-do run', although dg-do-what-default says otherwise, leading to
uninteresting failures.
Therefore, this patch removes all such unconditionnal 'dg-do run',
thus avoid link errors for instance if GCC has been configured with
multilibs disabled and some --with-{float|cpu|hard} option
incompatible with what check_vect_support_and_set_flags selects.
For exmaple, GCC configured with:
--disable-multilib --with-mode=thumb --with-cpu=cortex-m7 --with-float=hard
and check_vect_support_and_set_flags uses
-mfpu=neon -mfloat-abi=softfp -march=armv7-a
(thus incompatible float-abi options)
Tested on native aarch64-linux-gnu (no change) and several arm-eabi
cases where the FAIL/UNRESOLVED disappear (and we keep only the
'compilation' tests).
