[libc] Add environment variables to GPU libc test for AMDGPU 2023-03-20T18:16:58+00:00 Joseph Huber jhuber6@vols.utk.edu 2023-03-17T19:06:53+00:00 6bd4d717d577b88e83a92ea865bb96dd5df45936 This patch performs the same operation to copy over the `argv` array to the `envp` array. This allows the GPU tests to use environment variables. Reviewed By: sivachandra Differential Revision: https://reviews.llvm.org/D146322

[libc] Enable integration tests targeting the GPU 2023-03-17T17:55:32+00:00 Joseph Huber jhuber6@vols.utk.edu 2023-03-16T16:42:57+00:00 39e91098b58bfbef973bc759803fbfcc6064b42b This patch enables integration tests running on the GPU. This uses the RPC interface implemented in D145913 to compile the necessary dependencies for the integration test object. We can then use this to compile the objects for the GPU directly and execute them using the AMD HSA loader combined with its RPC server. For example, the compiler is performing the following actions to execute the integration tests. ``` $ clang++ --target=amdgcn-amd-amdhsa -mcpu=gfx1030 -nostdlib -flto -ffreestanding \ crt1.o io.o quick_exit.o test.o rpc_client.o args_test.o -o image $ ./amdhsa_loader image 1 2 5 args_test.cpp:24: Expected 'my_streq(argv[3], "3")' to be true, but is false ``` This currently only works with a single threaded client implementation running on AMDGPU. Further work will implement multiple clients for AMD and the ability to run on NVPTX as well.
