[Bug 11210] New: test_arb_vs_offset_limit() vertex program error

http://bugs.winehq.org/show_bug.cgi?id=11210

           Summary: test_arb_vs_offset_limit() vertex program error
           Product: Wine
           Version: unspecified
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: directx-d3d
        AssignedTo: wine-bugs(a)winehq.org
        ReportedBy: eric(a)anholt.net


While test_arb_vs_offset_limit() appears to intend to test the limits of
constant offsets from an address register, it also (I think) unintentionally
tests whether ARL accepts a floating point constant as the source value, which
is outside of the spec.  Excerpts from ARB_vertex_program spec:

    <ARL_instruction>      ::= "ARL" <maskedAddrReg> "," <scalarSrcReg>
    <scalarSrcReg>         ::= <optionalSign> <srcReg> <scalarSuffix>
    <srcReg>               ::= <vertexAttribReg>
                             | <temporaryReg>
                             | <progParamReg>
    <scalarSuffix>         ::= "." <component>
    <component>            ::= "x"
                             | "y"
                             | "z"
                             | "w"

While it may be that Mesa should also allow constants as ARL arguments, the
program should probably be fixed to test only the intended out-of-spec
behavior.

I fixed that bug some time ago. The program still tests the invalid offset, but
the ARL offset is fixed.

Note that real vertex programs generated from D3D shaders might still use "0.0"
in ARL. That isn't yet fixed, I'd be happy if Mesa would accept that, as
catching such situations would be a bit of pain, and we're pretty short on free
PARAMs, and we can't really throw away a float to load 0.0 into the shader.
