C2000 assembler bug in CGT v.15.12.1

I believe I have found an assembler bug in C2000 CGT v.15.12.1. The following two lines show the issue:

SUBF32 R2H, R3H, R7H
|| MOV32 R7H, *--SP, UNCF

After assembly, the code shown in the disassembly window is:

SUBF32 R2H, R7H, R7H
|| MOV32 R7H, *--SP

Note the second operand in the SUBF32 instruction is different.

Please let me know if more information is needed. Thanks.

The assembler doesn't like the UNCF at the end of the MOV32. As a workaround, take off the UNCF operand and the assembler handles the instruction correctly.

I've created CODEGEN-1534 to track this issue.

Thank you. I confirm removing UNCF works for me.
