A result of ccr and exr mistakes by a "info registers" of h8300 target. There was two faults. - A name of E_CCR_REGNUM is not defined with h8300_register_name. Accordingly regcache_raw_read of h8300_pseudo_regitser_read fails. - Assume size of E_PSEUDO_CCR_REGNUM by 1 byte with h8300_register_type. But assume 4 bytes from a remote target. Accordingly cannot take response of remote side to be really. I correct an issue of a thing of the patch box which I attached. The issue was corrected, but not know you whether this is good technique. -- Yoshinori Sato
