This will allow us to clean up some of the code base going forwards by being able to assume: - Presence of half-word data accesses - Presence of Thumb and therefore of interworking instructions. This patch records the status change in the GCC-6 release notes. I propose to commit this patch later this week. R.

Please + Support for revisions of the ARM architecture prior to ARMv4t has + been deprecated and will be removed in a future GCC release. + This affects ARM6, ARM7 (but not ARM7TDMI), ARM8, StrongARM, and + Faraday fa526 and fa626 devices, which do not have support for + the Thumb execution state. +
