is_use_frame

__vsf_eda_feature_word vsf_eda_feature_t::is_use_frame

Note

is_use_frame is used by vsf_peda and sub-call ! since both vsf_peda and sub-call will share most of the functions ! used for frame push and pop operation, it has little gain to ! only disable sub-call feature but keep vsf_peda. Hence, to reduce ! complexity, we only use VSF_KERNEL_CFG_EDA_SUPPORT_SUB_CALL to ! enable or disable the is_use_frame bit and frame related ! functions.
