* common/config/msp430/msp430-common.c (msp430_handle_option): Pass both -mmcu and -mcpu on to the back end if they are both defined. * config/msp430/msp430.c (hwmult_name): New function. (msp430_option_override): If an unrecognised MCU name is detected only warn if the user has not provided suitable -mhwmult and -mcpu options. Use msp430_warn_mcu to control warning messages. Generate warnings about conflicts between -mmcu and -mcpu and -mhwmult options. If neither -mcpu nor -mmcu have been specified but -mhwmult= f5series has the select the 430X isa. (msp430_no_hwmult): If -mmcu has not been specified and msp430_hwmult_type is AUTO then return true. * config/msp430/msp430.h (EXTRA_SPEC_FUNCTIONS): Define. (LIB_SPEC): Add hardware multiply library selection. * config/msp430/t-msp430: Delete hardware multiply multilibs. Add rule to build driver-msp430.o * config/msp430/driver-msp430.c: New file. * config/msp430/msp430.opt (warn-mcu): New option. * doc/invoke.texi: Update description of -mhwmult=auto. Document -mwarn-mcu option. tests * gcc.target/msp430/msp_abi_div_funcs.c: New test. * gcc.target/msp430/mul_main.h: New test support file. * gcc.target/msp430/mul_none.c: New test. * gcc.target/msp430/mul_16bit.c: New test. * gcc.target/msp430/mul_32bit.c: New test. * gcc.target/msp430/mul_f5.c: New test. libgcc * config/msp430/mpy.c (__mulhi3): Use a faster algorithm. Allow for the second argument being negative. * config.host (extra_parts): Define for MSP430. Create separate libraries for each of the hardware multiply formats. * config/msp430/lib2hw_mul.S: Build only the multiply routines that are needed. * config/msp430/lib2mul.c: Likewise. * config/msp430/t-msp430 (LIB2ADD): Remove lib2hw_mul.S. Add rules to build hardware multiply libraries. * config/msp430/lib2divSI.c: (__mspabi_divlu): Alias for __mspabi_divul function. (__mspabi_divllu): New stub function. From-SVN: r231286 |
