PK80425: SHIFT OPERATOR, CODE GENERATION, MICROC

APAR status

• Closed as Permanent restriction.

Error description

• Quintus defect 221289
  
  
  
  
  
  
           I used the shift operator in the following example:
  LSHL(U32(1),18)
  U32 is a subroutine used to be able to have an explicit typecast
  in
  generated code.
  
  The generated code is the following:
  
  TEST_VAR = ((TYPE_U8)(u32)(1)) ?? 18;
  
  The problem ist, that an additional, wrong typecast to TYPE_U8
  is
  generated. This makes problems because it I need to define the
  type of the
  shifted variable explicitly. Just using the type of the variable
  which is
  shifted is not sufficient, because often the type must be
  expanded.
  before. Doing this explicitly using another variable will cause
  a lot of
  overhead in my code and is therefore not possible.
  
  The code for the shift operation shall be generated WITHOUT the
  additional
  typecast, so that the user can specify the typecast on its own.
  

Local fix

• fixed in build 232233
  

Problem summary

• generated code for logical shift operator  is wrong
  

Problem conclusion

• Statemate MicroC Code Generator was enhanced to support
  function call inside a shifting operator expression
  

Temporary fix
