android: radeon: fix LLVMInitializeAMDGPU* functions declaration
LLVMInitializeAMDGPU* functions need to be explicitly declared and mesa expects them via <llvm-c/Target.h> header, but LLVM needs to be instructed to invoke its own LLVM_TARGET(AMDGPU) macro, or the functions will not be available. A new llvm cflag (-DFORCE_BUILD_AMDGPU) serves this purpose, the same mechanism is used also by other llvm targets e.g. FORCE_BUILD_ARM A necessary prerequisite is to have AMDGPU target handled accordingly in llvm config files i.e. {Target,AsmParser,AsmPrinter}.def for llvm device build includes. This avoids the following building errors: external/mesa/src/gallium/drivers/radeon/radeon_llvm_emit.c:121:2: error: implicit declaration of function 'LLVMInitializeAMDGPUTargetInfo' [-Werror=implicit-function-declaration] LLVMInitializeAMDGPUTargetInfo(); ^ external/mesa/src/gallium/drivers/radeon/radeon_llvm_emit.c:122:2: error: implicit declaration of function 'LLVMInitializeAMDGPUTarget' [-Werror=implicit-function-declaration] LLVMInitializeAMDGPUTarget(); ^ external/mesa/src/gallium/drivers/radeon/radeon_llvm_emit.c:123:2: error: implicit declaration of function 'LLVMInitializeAMDGPUTargetMC' [-Werror=implicit-function-declaration] LLVMInitializeAMDGPUTargetMC(); ^ external/mesa/src/gallium/drivers/radeon/radeon_llvm_emit.c:124:2: error: implicit declaration of function 'LLVMInitializeAMDGPUAsmPrinter' [-Werror=implicit-function-declaration] LLVMInitializeAMDGPUAsmPrinter(); ^ Acked-by:Nicolai Hähnle <nicolai.haehnle@amd.com> Acked-by:
