Field Documentation

arc_t* block_info::arc

         Single line graph cycle workspace.  Used for all-blocks
         mode.  

struct block_info* block_info::chain

     Temporary chain for solving graph, and for chaining blocks on one
     line.  

Referenced by make_gcov_file_name(), and mangle_name().

gcov_type block_info::count

     Block execution count.  

Referenced by get_gcov_intermediate_filename().

unsigned block_info::count_valid

struct { ... } block_info::cycle

Referenced by mangle_name().

unsigned* block_info::encoding

        Array of line numbers and source files. source files are
        introduced by a linenumber of zero, the next 'line number' is
        the number of the source file.  Always starts with a source
        file.  

unsigned block_info::exceptional

unsigned block_info::flags

unsigned block_info::ident

unsigned block_info::invalid_chain

unsigned block_info::is_call_return

unsigned block_info::is_call_site

     Block is a call instrumenting site.  

Referenced by read_graph_file().

unsigned block_info::is_nonlocal_return

     Block is a landing pad for longjmp or throw.  

Referenced by read_graph_file().

struct { ... } block_info::line

unsigned block_info::num

gcov_type block_info::num_pred

Referenced by read_graph_file().

gcov_type block_info::num_succ

     Number of unprocessed exit and entry arcs.  

Referenced by read_graph_file().

arc_t* block_info::pred

Referenced by mangle_name(), and read_graph_file().

arc_t* block_info::succ

     Chain of exit and entry arcs.
