Thanks Rob, I'll test build in the weekend on M, N
as in L libdrm and especially drm_gralloc/drm_hwcomposer require a lot of hacks
Following questions about LLVM:
I've seen that you unconditionally added libAMDGPU* whole static
libraries to libLLVM shared,
we were just discussing with Chih-Wei about keeping libLLVM gpu
agnostic as much as possible,
so if I understood it correctly it would be better to avoid setting
conditions to add libAMDGPU* based on radeonsi/swrast
and you consider safe to add libLLVMExecutionEngine,
libLLVMRuntimeDyld, libLLVMMMCJIT and libLLVMMOrcJIT to all targets.
We just added for x86/x86_64 and skipped libLLVMOrcJIT for the moment
is libLLVMOrcJIT necessary with LLVM 3.9.0 to build AOSP/O ?
Does the following BP part in shared libLLVM building rules mean that
those libraries are infact added for all targets besides x86/x86_64?
android: {
export_include_dirs: ["device/include"],
+ whole_static_libs: [
+ "libLLVMExecutionEngine",
+ "libLLVMRuntimeDyld",
+ "libLLVMMCJIT",
+ "libLLVMOrcJIT",
+ ] + llvm_amdgpu_static_libraries,
},
Thanks
Mauro
