            Bug ID: 111791
           Summary: mesa-19.2-rc4: Fails to execute OpenCL kernel (ac_rtld
                    error: !s->is_rx) on AMD64 and armhf at least
           Product: Mesa
           Version: 19.2
          Hardware: All
                OS: Linux (All)
            Status: NEW

          Priority: not set
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel at lists.freedesktop.org
          Reporter: luis.p.mendes at gmail.com
        QA Contact: dri-devel at lists.freedesktop.org

Cannot execute OpenCL kernel (https://github.com/huytd/opencl-benchmark) on GPU
with mesa 19.2-rc4 and libclc with AMD RX 550, AMD RX 460, neither on AMD64,
nor on armhf.

Kernels fails with:
ac_rtlf error: !s->is_rx
LLVM failed to upload shader

This also also happens with Aparapi kernels
(https://github.com/Syncleus/aparapi-examples) - test 15 or 16, or others.
