    broadcom/vc5: Use MSF to ignore discards/non-dispatched channels in loops.
    
    Prevents potential infinite loops when a non-dispatched or discarded
    channel never triggers the loop break condition.

    broadcom/vc5: Use XOR instead of SUB for execute flags comparisons.
    
    I think this should be equivalent other than power, and it's the kind of
    comparison we use for nir_op_ieq.

    broadcom/vc5: Also check the update flags for avoiding DCE.
    
    I was trying to do a NULL-destination UF, and it got removed.

    broadcom/vc5: Fix up channel swizzling for textures on 4.x.
    
    I had 3.x putting swizzling in the texture state only for 16-bit texture
    returns, and in the shader for 32-bit.  This may be due to having mixed up
    the return channel setup on 3.x back before I had moved it into the
    compiler.  On 4.x, the non-border-color texwrap tests are passing nicely
    with both 16 and 32-bit returns with swizzling in the texture state.

    broadcom/vc5: Rename V3D 3.x Flat Shade Action to match v4.x naming.
    
    Now that the actions are reused for centroid and nonperspective, give them
    a more generic name.

    broadcom/vc5: Update pixel center setup for V3D 4.x.
    
    The fxcd/fycd instructions now return half-integer pixel centers when not
    doing sample-rate shading.

    broadcom/vc5: Print the buffer name in simulator overflow checks.
    
    Revealed that I was writing past the TSDA, not the Z buffer as I expected.

    broadcom/vc5: Add support for loading varyings in V3D 4.1.
    
    The LDVARY signal now writes an arbitrary register, so I took out the
    magic src register file and replaced it with an instruction with LDVARY
    set so we have somewhere to hang a QFILE_TEMP destination for register
    allocation.

    broadcom/vc5: Add the new TMU write addresses for V3D 4.x (and r5rep).
    
    The V3D 3.x series of TMU writes with meaning depending on the texture
    type is replaced with writes to specific registers for each texture
    argument semantic.

    broadcom/vc5: Move V3D 3.3 texturing to a separate file.
    
    V3D 4.x texturing changes enough that #ifdefs would just make a mess of
    it.

    broadcom/vc5: Move V3D 3.3 VPM write setup to a separate file.
    
    For V4.1 texturing, I need the V4.1 XML, so the main compiler needs to
    stop including V3.3 XML.

    broadcom/vc5: Set up depth formats for V3D 4.x.
    
    We no longer have the small depth-specific output format enum, and instead
    depth is just at the end of the output image format enum.

    broadcom/vc5: Always use the RGBA8 formats for RGBX8.
    
    The RGBX8 formats were dropped from V3D 4.x, but we don't really need them
    anyway (we already handle other non-alpha formats by forcing A to 1).

    broadcom/vc5: Move the body of CLIF dumping to a per-version file.
    
    I want the library's entrypoints to still be unversioned, but the actual
    packet dumping needs to be per-version.

    broadcom/vc5: Use THRSW to enable multi-threaded shaders.
    
    This is a major performance boost on all of V3D, but is required on V3D
    4.x where shaders are always either 2- or 4-threaded.

    broadcom/vc5: Properly schedule the thread-end THRSW.
    
    This fills in the delay slots of thread end as much as we can (other than
    being cautious about potential TLBZ writes).
    
    In the process, I moved the thread end THRSW instruction creation to the
    scheduler.  Once we start emitting THRSWs in the shader, we need to
    schedule the thread-end one differently from other THRSWs, so having it in
    there makes that easy.

    broadcom/vc5: Implement GFXH-1684 workaround.
    
    Apparently the VPM writes need to be flushed out before we end the shader.

    broadcom/vc5: Port drawing commands to V3D 4.x.
    
    This required extending the CL submit ioctl, because the tile alloc/state
    buffer setup has moved from the BCL to register writes.

    broadcom/vc5: Add a test for .ifb in ADD ops.
    
    I had a .ifb being decoded weird in sampid, so this is to check that .ifb
    is fine.

    broadcom/vc5: Use a physical-reg-only register class for LDVPM.
    
    This is needed for LDVPM on V3D 4.x, but will also be needed for keeping
    values out of the accumulators across THRSW.

    broadcom/vc5: Use the new LDVPM/STVPM opcodes on V3D 4.1.
    
    Now, instead of a magic write register for VPM stores we have an
    instruction to do them (which means no packing of other ALU ops into it),
    with the ability to reorder the VPM stores due to the offset being baked
    into the instruction.
    
    VPM loads also gain the ability to be reordered by packing the row into
    the A argument.  They also no longer write to the r3 accumulator, and
    instead must be stored to a physical register.

    broadcom/vc5: Drop dead VC5_QPU_* defines from qpu_instr.c.
    
    I had all the packing code in this file at one point, but these defines
    now live in qpu_pack.c.

    broadcom/vc5: Port the simulator to support V3D 4.1
    
    This required moving the register accesses to a separate v3dx file, since
    the register definitions for each V3D version collide.  It seems that
    initializing the v3d_hw from a file dictating 3.3
    (v3d_simulator_wrapper.cpp) is safe, though.

    Signals are more complicated than that, and tables ended up being better.

    broadcom/vc5: Add support for V3Dv4 signal bits.
    
    The WRTMUC replaces the implicit uniform loads in the first two texture
    instructions.  LDVPM disappears in favor of an ALU op.  LDVARY, LDTMU,
    LDTLB, and LDUNIF*RF now write to arbitrary registers, which required
    passing the devinfo through to a few more functions.

    broadcom/vc5: Port the RCL setup to V3D4.1.
    
    The TLB load/store path is rebuilt in this version.  There is no longer a
    single-byte resolved store or the 3-byte extended store.  Instead, you get
    to always use general loads/stores (which, honestly, was tempting even in
    previous versions).

    broadcom/vc5: Fix per-tile extra clear packet.
    
    I accidentally emitted this into the RCL instead of the per-tile generic
    list, so we wouldn't get tiles after the first cleared.

    broadcom/vc5: Move the TLB loads and stores to helper functions.
    
    This is going to get more complicated with V3D 4.1 support, which redoes
    all the TLB packets.

    broadcom/vc5: Convert vc5_cl.h to use the V3DX() macros.
    
    To conditionally compile cl_emit() macros per V3D version, we need it to
    expand to whatever V3D we're building for.  This required emitting #define
    V3D_VERSION 33 in all our currently 3.3-only code.
