+
+ * config/arm/arm.h: Add TARGET_CPU_strongarm1100.
+ Add -mno-sched command line switch to disable scheduling of
+ instructions into the function's prologue.
+ (enum processor_type): Remove.
+ (TARGET_OPTIONS): Add "fpe=" option to match documentation.
+ (struct arm_cpu_select): Replace 'set_tune_p' and 'set_arch_p'
+ fields with 'processors' field.
+ (CONDITIONAL_REGISTER_USAGE): Allow r10 to be used if stack
+ checking is not enabled.
+ (RETURN_IN_MEMORY): Always call arm_return_in_memory.
+
+ * config/arm/arm.c: (arm_cpu): Remove.
+ (tune_flags): Remove.
+ (arm_is_strong): New variable: true iff the target processor is a
+ StrongARM.
+ (arm_is_6_or_7): New variable: true iff the target processor is an
+ ARM6 or and ARM7.
+ (arm_select): Fields reorganised.
+ (struct processors): processor_type field removed.
+ (all_procs): Remove.
+ (all_cores): New array: Definitions of all known ARM cpu cores.
+ (all_architectures): New array: Definitions of all known ARM
+ architectures.
+ (streq): New macro.
+ (FL_SCHED): New processor flag: processor required load
+ scheduling.
+ (FL_STRONG): New processor flag: processor is a StrongARM.
+ (arm_override_options): Reorganised to make code clearer.
+ (use_return_insn): Test for "not (TARGET_APCS and
+ frame_pointer_needed)".
+ (arm_return_in_memory): Improve handling of structures.

+
+ * config/arm/linux-gas.h (INITIALIZE_TRAMPOLINE): Replace default
+ definition with one including cache synchronisation.
+ (CLEAR_INSN_CACHE): Correct syscall number and enable definition.
+ Move definition of inhibit_libc to...
+ * config/arm/xm-linux.h: ... here.
+
+ * config/arm/t-linux: Disable multilib configurations since the
+ only effect for most people is to cause builds to fail.
+
+ * config/arm/elf.h (ASM_FILE_START): Add .file directive.
+ (ASM_SPEC): Translate -mapcs-float to -mfloat for the assembler.
+
+ * config/arm/linux-elf.h (DEFAULT_VTABLE_THUNKS): Define.
+ (HANDLE_SYSV_PRAGMA): Likewise.
+ (LIB_SPEC): Copy definition from generic Linux files.
+ (LIBGCC_SPEC): Include -lfloat if -msoft-float was given.
+ (FP_DEFAULT): Set to SOFT3 on 32-bit targets.
+ (DWARF2_DEBUGGING_INFO): Define.
+ (PREFERRED_DEBUGGING_TYPE): Define as DBX_DEBUG.
