Re: Commit: MSP430: Add -mcpu= option

2014-01-21 Thread nick clifton 

Hi Gerald,


command-line option, I think, and I suggest to use code.../code around 
the actual options.


OK - I have made those changes and committed the result.

Cheers

Hi Gerald,


Mind adding an entry to the release notes? Happy to help if you have any 
questions.


Is the following acceptable ?  I even remembered to run it through the 
validator...


Cheers

Commit: MSP430: Add -mcpu= option

2014-01-17 Thread Nick Clifton 
Hi Guys,

  I am committing the attached patch to add a -mcpu= command line option
  to the MSP430 backend.  This allows the selection of the ISA to be
  used, and it operates independently of the -mmcu= command line option.

gcc/ChangeLog
2014-01-17  Nick Clifton  ni...@redhat.com

* config/msp430/msp430.opt: (mcpu): New option.
* config/msp430/msp430.c (msp430_mcu_name): Use target_mcu.
(msp430_option_override): Parse target_cpu.  If the MCU name
matches a generic string, clear target_mcu.
(msp430_attr): Allow numeric interrupt values up to 63.
(msp430_expand_epilogue): No longer invert operand 1 of gen_popm.
* config/msp430/msp430.h (ASM_SPEC): Convert -mcpu into a -mmcu
option.
* config/msp430/t-msp430: (MULTILIB_MATCHES): Remove mcu matches.
Add mcpu matches.
* config/msp430/msp430.md (popm): Use %J rather than %I.
(addsi3): Use msp430_nonimmediate_operand for operand 2.
(addhi_cy_i): Use immediate_operand for operand 2.
