only inline functions, which is then included in two other files, then
there will be two .bb files which refer to the include file, but there
is no way to get the total execution counts for the included file, can
only get execution counts for one or the other of the including files. */

/* The .bb file format consists of several lists of 4-byte integers
which are the line numbers of each basic block in the file. Each
list is terminated by a zero. These lists correspond to the basic
blocks in the reconstructed program flow graph.
A line number of -1 indicates that a source file name (padded to a
long boundary) follows. The padded file name is followed by
another -1 to make it easy to scan past file names. A -2 indicates
that a function name (padded to a long boundary) follows; the name
is followed by another -2 to make it easy to scan past the function
name.
The .bbg file contains enough info to enable gcov to reconstruct the
program flow graph. The first word is the number of basic blocks,
the second word is the number of arcs, followed by the list of arcs
(source bb, dest bb pairs), then a -1, then the number of instrumented
arcs followed by the instrumented arcs, followed by another -1. This
is repeated for each function.
The .da file contains the execution count for each instrumented branch.
The .bb and .bbg files are created by giving GCC the -ftest-coverage option,
and the .da files are created when an executable compiled with
-fprofile-arcs is run. */

(__bb_exit_func): Use __read_gcov_type and __write_gcov_type. * profile.c (LONG_TYPE_SIZE, LONG_LONG_TYPE_SIZE): Set default. (GCOV_TYPE_SIZE): Define. (struct bb_info): succ_count and pred_count is gcov_type. (compute_branch_probabilities): Use __read_gcov_type, print read edges to the dump file. (total): Is gcov_type. (gen_edge_profiler): Use GCOV_TYPE_SIZE. From-SVN: r43505
