[PATCH 1/3] clang: move BPN assignment from common.inc

[PATCH 1/3] clang: move BPN assignment from common.inc

[Ross Burton]

There's a BPN assignment in common.inc which means all recipes need to
either be called clang, or set BPN themselves.

Move the assignment to the clang recipes. For now I'm leaving the
existing BPN assignments in the other recipes, in case there are complex
multilib-related reasons to retain them.

[PATCH 2/3] llvm-tblgen-native: add new recipe

[Ross Burton]

Building the LLVM projects often means using the TableGen tools
(llvm-tblgen etc).

We currently build them as part of clang-native, but I am teasing the
clang recipe into its component parts and having to build llvm-native
or lldb-native simply for one tool isn't ideal.

Instead, add a native recipe that simply builds the tablegen binaries
for llvm, clang, and lldb

[PATCH 3/3] lldb: add new recipe, split out of clang

[Ross Burton]

LLDB takes a reasonable amount of time to compile, but also isn't an
essential component of the LLVM suite.

Instead of always building it when we build clang, split it out into a
separate recipe.

On my build machine where clang takes 21 minutes to build with lldb, it
takes 19 minutes without lldb.

RE: [OE-core] [PATCH 1/3] clang: move BPN assignment from common.inc

[Marko, Peter]

I think that the inc file should now set CVE_PRODUCT when we remove the BPN assignment.
Having a recipe based on clang sources without BPN assignment would mean wrong CVE stats.

they are not installed but They are still being built internally I 
suppose ? in that case I wonder if it can use the binaries from 
llvm-tblgen-native during build and we can disable them from build in 
clang-native explicitly, should save some more time

Annoyingly, the native build does build its own copies even though I’ve told it where to find existing binaries.  Probably some quirk or another argument needed, feel free to figure out what I’m missing ;)

Hi Ross,

I know you are already aware of this, but just to keep a trace, this is
failing reproducibility test on the autobuilder.

https://autobuilder.yoctoproject.org/valkyrie/#/builders/37/builds/2088
