Some regression tests don't compile with gcc version 4.8.1 (GCC) using the
armv5 switches
-march=armv5te -marm -mthumb-interwork.
The first to fail is atomic_incs.c which reports for example:
Error: selected processor does not support ARM mode `ldrexb r8,[r9]'
Error: selected processor does not support ARM mode `strexb r4,r8,[r9]'
...
The ARM instruction ldrex was added introduced with v6.
A grep found ldrex references in VEX/priv/(host_arm_defs.c host_arm_isel.c
host_arm_defs.c).
Has "https://bugs.kde.org/show_bug.cgi?id=248998 ARMv5 and v6 support" been
incorporated into release 3.8.1 so that support is now available for ARMv5 and
ARMv6. Or will execution on an ARMv5 target crash with SIGILL due to execution
of the unimplemented instructions. I'm seeing another valgrind early failure
on the target but don't want to try and debug (or note) that failure if ARMv5
is not officially supported.
