Hi toolchain gurus,
I am about to start some projects working with CortexMx devices and am wondering if anyone has an opinion on which toolchain(s) I should use/investigate?
Being a fan of Linaro, my first instinct would be to use cbuild2 to build an arm-none-eabi- toolchain from a 4.8.x tree. But looking around I can't help notice https://launchpad.net/gcc-arm-embedded.
Does anyone know if gcc-arm-embedded has things the Linaro toolchain doesn't wrt Cortex M0, M3, and M4 device/instruction support?
Best regards, Trevor

Yes. The https://launchpad.net/gcc-arm-embedded supports Cortex M0, M3, and M4.

What about https://launchpad.net/gcc-linaro/? Does https://launchpad.net/gcc-linaro/ support these three families as well as gcc-arm-embedded supports them?

No. Linaro toolchain does not have the libraries for Cortex-M.

Thank you. That's exactly the information I was hoping to find :-)

Debian also has (stricly will have RSN - they've been waiting in the NEW queue for a month so far) arm-none-eabi- toolchains supporting M0, M3, and M4.
Won't have most un-upstreamed linaro optimisations, but is handy to install.
http://ftp-master.debian.org/new/binutils-arm-none-eabi_3.html http://ftp-master.debian.org/new/gcc-arm-none-eabi_3.html
I expect they'll be available in unstable/sid soon.
