This is the minified shader I did the debugging with.

translating program of type 4
FRAG
DCL IN[0], GENERIC[9], PERSPECTIVE
DCL OUT[0], COLOR
DCL SAMP[0]
DCL TEMP[0..2], LOCAL
IMM[0] FLT32 {    0.0000,     1.9632,     0.8750,     0.0000}
  0: MOV TEMP[0].xy, IN[0].xyyy
  1: MOV TEMP[0].w, IMM[0].xxxx
  2: TXL TEMP[0].xyz, TEMP[0], SAMP[0], 2D
  3: MOV TEMP[1].xyz, TEMP[0].xyzx
  4: MAD TEMP[0].x, TEMP[0].yyyy, IMM[0].yyyy, TEMP[0].xxxx
  5: FSLT TEMP[0].x, TEMP[0].xxxx, IMM[0].zzzz
  6: UIF TEMP[0].xxxx :0
  7:   MOV TEMP[0].xy, TEMP[2].xyyy
  8:   MOV TEMP[0].w, TEMP[2].zzzz
  9:   TXL TEMP[0].xyz, TEMP[0], SAMP[0], 2D
 10:   MOV TEMP[1].xyz, TEMP[0].zyxz
 11: ENDIF
 12: MOV TEMP[0].xyz, TEMP[1].xyzx
 13: MOV TEMP[0].w, IMM[0].xxxx
 14: MOV OUT[0], TEMP[0]
 15: END
