Building a hexagon cross compiler

Building a hexagon cross compiler

[David Howells]

Hi Richard,

I'd like to build a Hexagon cross-compiler to go with the other Fedora cross
compilers that I have.  I don't see support in binutils-2.24 and gcc-4.9.0
though.  Do I take it that Hexagon has its own special cross compiler build?

Last time I used this (many years ago) it all worked great, with almost all of the glibc test suite passing, including the wild tangle of thread-local storage, thread joins, thrown exceptions, stack unwinding, gdb and signals all happening at the same time. There were only a handful of rare, obscure cases that didn't pass.  I know, as I did the work to make this all go.

Sorry for the late response.  As Linas mentioned, Mentor maintains the that
set of tools.  That latest version that was released can be found here:

https://sourcery.mentor.com/GNUToolchain/release2800

I haven't had a chance to test these tools myself though.

Hope that helps.

gcc-4.6 and a similarly aged binutils.  Do they have anything newer, and can
they push it upstream?

Unfortunately, it looks like 'no' on both counts.  The focus is on ... other
toolchains at the moment.
