What's New in C251 Version 5.07b

• [C Run-Time Library]
  Corrected: the functions memcmp, hmemcmp, strcmp, strncmp, and hstrcmp now compare the memory content using unsigned char (instead of signed char) data types.
• [C251 Compiler]
  Corrected: problem with constant folding in address calculation. Example:

    unsigned char array[0x2000];
    unsigned long l1, l2;
  
    void foo(void)  {
    l1 = ((((unsigned long)array) + (0x100)) + (0x80));       // incorrectly calculated in previous versions
    l2 = ((((unsigned long)&(array[0])) + (0x100)) + (0x80)); // work-arround
  }
  

• [µVision4]
  This C251 release comes with µVision V4.22.00.
