            Bug ID: 99748
           Summary: [radeonsi] Civ6 Assert in LLVM SIMachineScheduler.cpp
                    with R600_DEBUG=sisched
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel at lists.freedesktop.org
          Reporter: mike at fireburn.co.uk

When running Civ6 using LLVM from git (SHA1's tested
1648ceaabcea762590049a74ce8b934e3bfd4fb2 and
897444660daf9e94c020efc97b63aed7e61db7ac) with R600_DEBUG=sisched and the
latest Mesa it would assert with the following error:

Civ6:
/var/tmp/portage/sys-devel/llvm-9999/work/llvm-9999/lib/Target/AMDGPU/SIMachineScheduler.cpp:1584:
void llvm::SIScheduleBlockScheduler::blockScheduled(llvm::SIScheduleBlock*):
Assertion `LiveRegsConsumers[RegP.first] == 0' failed.

This doesn't happen with LLVM-4.0.0-rc1 even when using R600_DEBUG=sisched
