srini said, in [tickets:#9],
a. can we use the Ada.Containers packages with the ARM cross compiler. If so apart from RAM limitations, what other restrictions are there?

#9There are two problems: first, I've only included a limited subset of the full RTS, and there’s no Ada.Containers code in there; and second, the restrictions I’ve imposed (see package System) mean that they couldn’t be used (yet). Specifically, No_Allocators means you can only use the Containers that don’t involve memory allocation (i.e. Ada.Containers.Bounded_Vectors); and even then No_Dispatch means you couldn’t compile the subprograms that take ‘Class even if I’d included Ada.Streams and Ada.Iterator_Interfaces.
It shouldn’t be too hard to solve these problems; I chose the simplest FreeRTOS memory allocator possible, which has a mere 15k of memory to be used for all the task stacks and doesn’t support deallocation, but there are three others and we could always roll our own.
The 20150406 release includes Bounded_Vectors and Bounded_Hashed_Maps, The new iterators (for some F in Foo loop ...) are NOT supported (they require finalization). See the README for this distribution.

The 20160314 release supports generalized iteration over containers ("for all E of C
loop"). Note, this is achieved by removing tampering checks. While
tampering errors are rare, it would be as well to check algorithms
using a fully-featured desktop compiler.
