As opposed to CodeSourcery package, this one included wide collection of libraries. Since then updated versions appear 3-4 times a year and include the most recent version of the compiler, coming from the branch targeting embedded microcontrollers (at that time - /branches/ARM/embedded-4_6-branch, currently - /branches/ARM/embedded-4_7-branch). It is pretty obvious that main target of linaro are application processors with ARM Cortex-A core and systems like Linux and Android, but at the end of 2011 first version of package named GNU Tools for ARM Embedded Processors was published. Suggestions about adding FPU support for ARMv7-ME architecture are dismissed with information that it (and many more) is available in the paid version.įortunately at the same time ( 2010) linaro organization is started, consisting of ARM and a few of its biggest partners, with purpose to develop and support open-source tools for new chips with ARM cores.

Additionally in 2010 CodeSourcery was purchased by Mentor Graphics and support for free Lite version becomes almost non-existent.

Would use 100% software algorithms instead of FPU-goodness. If you're in a mood you could always use assembly language or use CMSIS functions, but basic stuff like: float a = 1.0f You could - of course - write code for Cortex-M4, with this toolchain, as ARMv7-ME is just an extension of ARMv7-M architecture, but you need to forget about using the FPU ( Floating Point Unit) in most cases. To cut things short, it means that this toolchain includes standard libraries (like libm.a with math functions) only for "standard" ARM7 architecture ( ARMv4, both ARM and THUMB mode), for Cortex-M0 ( ARMv6-M, THUMB) and for Cortex-M3 ( ARMv7-M, THUMB2).

#Bleeding edge tool full
In the ancient times (which would be about 3-4 years ago [ ), when ARMs started to become really popular (with Cortex-M3 chips), the best choice for a toolchain was CodeSourcery - there were versions for Windows and Linux, package was updated regularly, developers from the company working on it were said to cooperate with ARM - full service, all you ever needed. "On the market" we already have CodeSourcery (now known as Sourcery CodeBench), linaro, Yagarto, and - if you insist - there are also prehistoric GNUARM and WinARM packages, and probably some more which I don't know about (yet) - so why another one? You cannot even use a cool name for it, as Yet Another Gnu ARm TOolchain is already taken ( Bleeding-edge-toolchain - what it's all about?Īs some of you probably noticed a new category appeared in Download section - Software > bleeding-edge-toolchain - with some pretty huge files names in a way that implies these are bare-metal compilers for chips with ARM cores.
