Blocks and block identifiers in C and C++ programs

In the program above, the function sort has the following three blocks:

The following examples set a breakpoint on entry to the second block of sort:

• If program is compiled with the ISD compiler option: at entry sort:>%BLOCK2;.
• If program is compiled with the DWARF compiler option: at entry sort:>%BLOCK8;.

The following example sets a breakpoint on exit of the first block of main and lists the entries of the sorted table.

at exit main {
  for (i = 0; i < length; i++)
    printf("table entry %d is %d\n", i, table[i]);
}

The following examples list the variable temp in the third block of sort. This is possible because temp has the static storage class.

• If program is compiled with the ISD compiler option: LIST sort:>%BLOCK3:temp;.
• If program is compiled with the DWARF compiler option: LIST sort:>%BLOCK13:temp;.
