Heinrich Schuchardt 0c1456d571 ARM: correct detection of thumb mode ... When a crash occurs in thumb mode the crash dump is incorrect. This is due to the usage of a non-existing configuration variable CONFIG_ARM_THUMB in the definition of macro thumb_mode(regs). Use CONFIG_IS_ENABLED(SYS_THUMB_BUILD) to detect that the code has been compiled for thumb mode. Remove ARM_THUMB from config_whitelist.txt. With the patch crash dumps indicate thumb mode correctly. On a system with thumb mode: => exception unaligned data abort pc : [<8f7a2b52>] lr : [<8f7ab1ef>] reloc pc : [<1780cb52>] lr : [<178151ef>] sp : 8ed8c3f8 ip : 8f7a2b4d fp : 00000002 r10: 8f7f8228 r9 : 8ed95ea8 r8 : 8ed99488 r7 : 8f7ab141 r6 : 00000000 r5 : 8ed8c3f9 r4 : 8f7f6390 r3 : 8ed9948c r2 : 00000001 r1 : 00000000 r0 : 8f7f6390 Flags: nzCv IRQs off FIQs off Mode SVC_32 (T) Code: 8f7e 466d f105 0501 (e9d5) 6700 The Flags line has '(T)' and in the Code line the output is in u16 groups.
