--- Comment #4 from Nick Clifton <nickc at redhat dot com> --- Hi Peter, > In mspgcc, TI provided a CSV file that listed every device along with all > its characteristics. This is still present in the GCC header bundle TI > provides. This in turn was processed to produce a specs fragment that > provided rules to default all the -m* flags from a specific -mmcu= value. Could the tool that converted the CSV file into a spec fragment be altered so that it produces the relevent -mhwmult= option based upon an MCU input ? Ie would it be possible to provide the users with a tool that takes an MCU name, reads in the CSV file and outputs the correct -mhwmult option ? Somthing like: msp430-elf-gcc `gen-hwmult-opt -mmcu=foo` If the tool was stand-alone then it would not need to be updated when the CSV file changes, and it could work with any CSV file, old or new. Cheers Nick PS. I have applied the patch to the newlib sources so that at least that part of the problem is resolved for now.
