If I have to wait for next stage 1, I can also try to refactor
write_one_data() after your patch which removes the buffering.
Yes, please build your patches on top of the file buffering removal.
Ok.
This would avoid some duplicated code, however, it would require some
changes in existing code. Is it allowed to remove external (hidden?)
symbols from libgcov?
Which functions do you mean?
Refactoring write_one_data() to use hooks requires that
gcov_write_counter()
gcov_write_tag_length()
gcov_write_summary()
move from gcc/gcov-io.c to libgcc/libgcov-buffer.c. They can be made
static. I am not sure if the external symbols can be removed
/* In libgcov we need these functions to be extern, so prefix them with
__gcov. In libgcov they must also be hidden so that the instance in
the executable is not also used in a DSO. */
#define gcov_write_tag_length __gcov_write_tag_length
#define gcov_write_counter __gcov_write_counter
#define gcov_write_summary __gcov_write_summary
