These ‘-m’ options are defined for V850 implementations:
-mlong-calls-mno-long-calls-mno-ep-mepep register, and
use the shorter sld and sst instructions. The -mep
option is on by default if you optimize.
-mno-prolog-function-mprolog-function-mspace-mtda=nep points to. The tiny data
area can hold up to 256 bytes in total (128 bytes for byte references).
-msda=ngp points to. The small data
area can hold up to 64 kilobytes.
-mzda=n-mv850-mbig-switch-mapp-regs-mno-app-regs-mv850e1-mv850eIf neither -mv850 nor -mv850e nor -mv850e1 are defined then a default target processor will be chosen and the relevant ‘__v850*__’ preprocessor constant will be defined.
The preprocessor constants ‘__v850’ and ‘__v851__’ are always
defined, regardless of which processor variant is the target.
