      When CLA code has a variable named "t" and compiled with --abi=eabi, the assembler generates below errors.

      The actual bug is that the CLA compiler is not emitting the vertical escape bars around variable names in assembly. EABI requires these vertical escape bars to distinguish variable names from assembler keywords. In this case the variable t is the same name as the register T.

      The attached CLA file has these lines ...

      extern float t;
__interrupt void Cla1Task3 ( void )
{
    t = 1.0f;
}

      Build it ...

      % cl2000 -@options.txt --src_interlist file.cla

>> Compilation failure

      Rename the variable t to something else like temp, and it builds clean.
