This is continuation of work from previous release that did not create
nativesdk artifacts properly.
Pytorch GLOW xNN compiler allows Ahead-of-Time compilation of neural network
models into CPU object file (for target architecture) using LLVM.
This requires LLVM compiler version 7 or later. Now, the 2020LTS LLVM candidate
from oe-core master branch is imported, to avoid unnecessary future upgrades
(LLVM8.0.1 version).
Also, there are several native tools that are part of GLOW project that need to
be compiled using CLANG/LLVM compiler (from branch 8.0), that is separately
pulled in for that
sole purpose (since oe-core does not include CLANG compiler).
Natively compiled tools are used for further building of nativesdk GLOW package
which includes single AOT tool, image-classifier, that is deployed in
linux-devkit.
End user could use this tool to compile its own xNN model into ARMv7 object
file and link with its application. An example, demo-glow, is provided in top
level Makefile and example-application.
Small, well known mnist xNN model and several test images, are included in the
filesystem.
Djordje Senicic (5):
mesa,llvm,meson: Update llvm to 8.0.1 plus define and use LLVM version
globally
clang8-native: llvm and clang used only for compilation of native
tools for glow compiler
glow: Address devkit related RPATH issue to point to devkit shared
libraries instead of host native
demo-glow: Restore in top-level makefile examples after recipe cleanup
packagegroup-arago-tisdk: Include xNN glow based compiler tool into
devkit, and demo-glow example
