At some point between 4.0 and 4.1 the mechanism for option handling was changed over to the new style using the .opt file but the default setting of quickcall seems to have been lost in the process.
It seems to me that this was unintentional - but please let me know if otherwise. adding the following 2 lines into h8300.c #undef TARGET_DEFAULT_TARGET_FLAGS #define TARGET_DEFAULT_TARGET_FLAGS (MASK_QUICKCALL) immediately before the line struct gcc_target targetm = TARGET_INITIALIZER; appears to fix the problem allthough I am not sure that this is completely the correct way to do this. regards Mike Lerwill
