Code Coverage Report

The code coverage report juxtaposes the assembly source code with
dynamic profile information pertaining to the code generated for
that source. The report provides, for each source line that
corresponds to an assembly instruction, the number of times control
has passed through that instruction and the total number of
machine cycles spent in executing the instruction. For conditional
instruction, the number of times the condition has evaluated to
TRUE is also provided. For DO-type instructions (DO, DOR, DO
FOREVER) the cycle count provided is the total number of cycles
spent executing the corresponding loop, not just the DO instruction
itself. For each source line containing a macro invocation which
resulted in expansion into more than one instruction, the
instructions expanded by the macro invocation are displayed in
disassembly form. Example C-6 depicts part of the Code Coverage
Report, in ASCII format.
