Here is a general but not absolute summary.

GCC ARM Embedded (call Embedded later) is tuned for Cortex-M/R. Linaro GCC
(call Linaro later) is tuned for Cortex-A.
Embedded values code size more than performance. Linaro vice versa.

Embedded has a longer release cycle (1 year) and longer maintenance cycle
(2 years). Usually no features or optimizations will be added in
maintenance period. Linaro has monthly release to follow closely to
mainline with latest optimization for newest processors.

Embedded mainly targets bare-metal or RTOS applications. Linaro mainly
targets Linux/Andriod kernel/applications.

Thanks Joey Ye, that solved my question.

What is the relationship between gcc-arm-embedded and linaro-gcc? Is one or the other upstream or are they independent?

At the risk of some serious thread hijacking but for better context, this question is prompted by an issue with "__INLINE" c code that crashed the gcc-arm-embedded gdb. On the surface, this appears to have been addressed in linaro-gcc, here:
https://bugs.launchpad.net/gdb-linaro/+bug/711375

Hence my curiosity regarding up or downstream relationships between the two projects.

Thank you for your time and for the wonderful toolchain.
