Recently work has been done with clang/llvm/lld to extend support for
Qualcomm's Hexagon DSP to a Linux target. At this point the publicly
available LLVM tools are able to build and run Hexagon programs via QEMU.
I've attached a patch that add the Hexagon bits to musl. The optimized
routines have been purposely omitted to keep the size and complexity to a
minimum.
The changes are being mirrored here:
https://github.com/quic/musl/tree/hexagon
The QEMU mirror is here: https://github.com/quic/qemu
A description of the assembly language is here:
https://developer.qualcomm.com/download/hexagon/hexagon-v5x-programmers-refe
rence-manual.pdf?referrer=node/6116
The objective is to have enough freely available tools and libraries that
any user could develop code for the DSP. The C-library is an important part
of that stack and this patch is intended to start a discussion of what would
need to happen in order for Hexagon to be added to the musl sources.
I've tested this using libc-test (git://repo.or.cz/libc-test) and 56 errors
are reported. The support for Hexagon in QEMU is on-going and while some of
the errors (math) may be attributed to QEMU most also happen on hardware. A
good chunk fail due to floating point exception status or precision.
Beyond the above testing a large number of packages have been built using
buildroot with our internal llvm tools. No issues outside of tweaks to
avoid glibc assumptions were seen.
