Hi Everyone,
I'm using an msp430f235 which has a 16x16 hardware multiplier but the
msp430-gcc does not produce code to utilise the hardware multiplier,
instead it generates a software multiply function.
My final linker command looks like the following:
/usr/bin/msp430-gcc -mmcu=msp430f235 -mmpy=16 -O2
-Wa,-adhlns=output/S5S.elf -o output/S5S.elf output/.obj/Main.o
output/.obj/SysConf.o output/.obj/System.o output/.obj/Version.o
output/.obj/hw_io.o output/.obj/FCell.o
I'm using the following gcc version from the arch linux distro
msp430-gcc (mspgcc_20120406) 4.6.3 20120301 (mspgcc LTS 20120406 unpatched)
What am I doing wrong? How do I get gcc to utilise the HW multiplier
correctly (with interrupt disabling)?
Thanks,
James
