Hello Ramana,
> I've always seen this turned on when bootstrapping FSF trunk with no special > configuration options. You are correct, sorry for the confusion. I checked again and it is indeed turned on also with --with-arch=armv7-a. When configuring without --with-arch=armv7-a and using -mthumb flag thumb-1 is been tested. In this case cbranchne_decr1 instruction is recognized as do-loop and the generation of the debug_insn for it interferer with SMS in stage 2 of the bootstrap (when -gtoggle is used) and thus the bootstrap fail. When running with --with-arch=armv7-a the new do-loop support for thumb-2 is used and the bootstrap passes as such debug_insn is not created for the do-loop part.
