Hi Rob, Emil,
I tested building r300g, r600g, radeonsi together and the build is broken,
due to multiple symbols defintion, which happens due to the use of
LOCAL_WHOLE_STATIC_LIBRARIES := \
$(gallium_DRIVERS) \
...
prebuilts/gcc/linux-x86/x86/x86_64-linux-android-4.9/x86_64-linux-android/bin/ld:
error:
out/target/product/x86_64/obj_x86/STATIC_LIBRARIES/libmesa_pipe_radeon_intermediates/libmesa_pipe_radeon.a(cayman_msaa.o):
multiple definition of 'cayman_emit_msaa_config'
prebuilts/gcc/linux-x86/x86/x86_64-linux-android-4.9/x86_64-linux-android/bin/ld:
out/target/product/x86_64/obj_x86/STATIC_LIBRARIES/libmesa_pipe_radeon_intermediates/libmesa_pipe_radeon.a(cayman_msaa.o):
previous definition here
[repeating for all other symbols]
So now we need revert or correct to support radeonsi also, as before
it was working,
and have 'r300g U r600g U radeonsi' support is better that having the
choice between 'r300g' and 'r300g U r600g'.
BTW, Rob have you tested the llvm 3.9.0 branch I provided for radeonsi
building purposes, does it build with AOSP/O preview?
Thanks
Mauro
PS: Moving libmesa_amdgpu_addrlib would cause the same duplication of symbols.
