New Revision: 231286
URL: https://gcc.gnu.org/viewcvs?rev=231286&root=gcc&view=rev
Log:
gcc * config.gcc (extra_gcc_objs): Define for MSP430.
* 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.
