HLSL parsing error when constructing half3x3 variable from 4 half3 arguments

[SSPkrolik]

Here is a place in my fragment shader where the error happens (lines 186-188):

  fFlipNormal*=IN.bIsFrontFace?1.0f:-1.0f;   // line 186
  half3x3 mTangentToWS=half3x3(half3(1,0,0),half3(0,1,0),half3(0,0,1));  // line 187
  mTangentToWS=half3x3(IN.vTangent.xyz,IN.vBinormal.xyz,IN.vNormalWS.xyz*fFlipNormal);  // line 188

Here is the output of glslValidator utitliy:

rostislavd@rostislavd-VirtualBox:~/Projects/glslang/build$ install/bin/glslangValidator -D -V ../../Shaders/illumZPassPS.frag

SPIR-V is not generated for failed compile or link

DirectX11 shader compiler compiles it just fine. Also I hadn't found that the feature is absent for HLSL parsing in issue #362

It is the fourth line of #362:

Map half to float. See issue #492.

Is mapping half -> float sufficient for you? (Assuming that means mapping all half* types to corresponding float* types.)

[SSPkrolik]

@johnkslang thx a lot, missed it. Yeah, the mapping would be quite enough.

This should work now with 96f6552. FXC also complains if you try to use 4 half3 arguments, so I assume the title is a typo. The code example only has 3, and my testing shows this works now.
