Yes, there it is:

TESS_CTRL
PROPERTY TCS_VERTICES_OUT 9
DCL IN[][0], POSITION
DCL SV[0], INVOCATIONID
DCL SV[1], VERTICESIN
DCL OUT[0], TESSOUTER
DCL OUT[1], TESSINNER
DCL OUT[][2], GENERIC[0]
DCL OUT[][3], GENERIC[1]
DCL TEMP[0..3], LOCAL
DCL ADDR[0..1]
IMM[0] FLT32 {   21.0000,     0.5000,     0.0000,     1.0000}
IMM[1] INT32 {3, 4, 0, 0}
  0: MOV OUT[1].x, IMM[0].xxxx
  1: MOV OUT[1].y, IMM[0].xxxx
  2: MOV OUT[0].x, IMM[0].xxxx
  3: MOV OUT[0].y, IMM[0].xxxx
  4: MOV OUT[0].z, IMM[0].xxxx
  5: MOV OUT[0].w, IMM[0].xxxx
  6: MOD TEMP[0].x, SV[0].xxxx, IMM[1].xxxx
  7: I2F TEMP[0].x, TEMP[0].xxxx
  8: MUL TEMP[0].x, TEMP[0].xxxx, IMM[0].yyyy
  9: IDIV TEMP[1].x, SV[0].xxxx, IMM[1].xxxx
 10: I2F TEMP[1].x, TEMP[1].xxxx
 11: MUL TEMP[1].x, TEMP[1].xxxx, IMM[0].yyyy
 12: LRP TEMP[2], TEMP[0].xxxx, IN[1][0], IN[0][0]
 13: LRP TEMP[3], TEMP[0].xxxx, IN[3][0], IN[2][0]
 14: UARL ADDR[1].x, SV[0].xxxx
 15: LRP OUT[ADDR[1].x][3], TEMP[1].xxxx, TEMP[3], TEMP[2]
 16: USEQ TEMP[2].x, SV[1].xxxx, IMM[1].yyyy
 17: UIF TEMP[2].xxxx :0
 18:   MOV TEMP[2].zw, IMM[0].wwzw
 19:   MOV TEMP[2].x, TEMP[0].xxxx
 20:   MOV TEMP[2].y, TEMP[1].xxxx
 21:   MOV TEMP[0], TEMP[2]
 22: ELSE :0
 23:   MOV TEMP[0], IMM[0].zzzz
 24: ENDIF
 25: UARL ADDR[1].x, SV[0].xxxx
 26: MOV OUT[ADDR[1].x][2], TEMP[0]
 27: END

Can you give me some tip to fix it, or do you think this can be sent in
another patch rather than the tgsi and the nouai part?

Thanks
