Re-implement ARM_DECLARE_FUNCTION_NAME as a function. That will make
changed related to unified/divided and mode directives easier to insert.
Thanks
Christian
2014-09-23 Christian Bruel <christian.br...@st.com>
* config/arm/arm-protos.h (arm_declare_function_name): Declare.
(is_called_in_ARM_mode): Remove.
* config/arm/arm.c (is_called_in_ARM_mode): Declare static bool.
(arm_declare_function_name): Moved from from ARM_DECLARE_FUNCTION_NAME.
* config/arm/arm.h (ARM_DECLARE_FUNCTION_NAME): Call
arm_declare_function_name.
