Source: pocl Version: 5.0-1 Followup-For: Bug #1059511 I cost some time to try to fix the issue, progress is below.
Inspired by the commit: https://github.com/pocl/pocl/issues/1088#issue-1340373438 If i build pocl by manual if follow: ``` cmake .. -DCMAKE_INSTALL_PREFIX='/usr' -DCMAKE_BUILD_TYPE='Debug' -DPOCL_DEBUG_MESSAGES=ON -DLLC_HOST_CPU='sifive-u54' ``` Then there are four test failed: ``` 98% tests passed, 4 tests failed out of 263 Label Time Summary: EinsteinToolkit = 190.88 sec*proc (2 tests) cuda = 279.87 sec*proc (42 tests) dlopen = 0.52 sec*proc (3 tests) hsa = 35.00 sec*proc (4 tests) hsa-native = 1127.40 sec*proc (82 tests) internal = 3317.43 sec*proc (256 tests) kernel = 1719.95 sec*proc (76 tests) level0 = 1446.25 sec*proc (124 tests) matrix = 40.41 sec*proc (4 tests) poclbin = 38.95 sec*proc (4 tests) proxy = 327.09 sec*proc (36 tests) regression = 933.17 sec*proc (95 tests) runtime = 179.38 sec*proc (31 tests) tce = 69.97 sec*proc (9 tests) vulkan = 176.65 sec*proc (26 tests) workgroup = 472.82 sec*proc (31 tests) Total Test time (real) = 3791.39 sec The following tests did not run: 62 - kernel/test_shuffle_half_loopvec (Skipped) 63 - kernel/test_shuffle_half_cbs (Skipped) 190 - runtime/clGetKernelArgInfo (Disabled) 199 - runtime/test_buffer_migration (Skipped) 200 - runtime/test_buffer_ping_pong (Skipped) The following tests FAILED: 76 - kernel/test_printf_vectors_loopvec (Failed) 77 - kernel/test_printf_vectors_cbs (Failed) 78 - kernel/test_printf_vectors_ulongn_loopvec (Failed) 79 - kernel/test_printf_vectors_ulongn_cbs (Failed) Errors while running CTest ``` Obviously these tests failed was due to vectors missing from riscv64 now. This is expected I think. The result is aligned with pocl upstream support riscv64: ``` In this release we improved support for RISC-V CPUs. We tested PoCL on a Starfive VisionFive 2 using a Ubuntu 23.10 preinstalled image. With LLVM 17 and GCC 13.2, 98% tests pass (only 4 tests fail out of 253). ``` http://portablecl.org/docs/html/notes_5_0.html#risc-v-cpu-support-improved If glance at the buildd log from riscv64: ``` -- udivmodti4 compiles without extra flags -- Checking if LLVM is a DEBUG build -- DEBUG build -- Find out LLC target triple (for host riscv64-unknown-linux-gnu) -- Find out LLC host CPU with /usr/bin/llc-15 -- Autodetected CPU sifive-u74 overridden by user to GENERIC -- Checking clang -march vs. -mcpu flag -- Using -None= -- Running LLVM link test -- LLVM link test OK ``` https://buildd.debian.org/status/fetch.php?pkg=pocl&arch=riscv64&ver=5.0-1&stamp=1704805199&raw=0 So I suspect the `LLC_HOST_CPU='` was overriden by `GENERIC` then the ABI was different. I will look at this more deeper. -- Regards, -- Bo YU
