* Summary:
This is used for printing what is about to happen between the current and last
builds, for example:
$ bitbake core-image-sato
# Edit some recipes
$ bitbake-whatchanged core-image-sato
The changes will be printed.
* Usage:
bitbake-whatchanged [[opts] recipe]
* Implementation summary:
- Use the "STAMPS_DIR=<path> bitbake -S recipe" to generate the new
stamps, compare these stamps to the one in the old stamps dir (tmp/stamps),
so we will get what are changed.
- When the "-v" (verbose) is not specified:
> Figure out the newly added tasks
> Figure out the PV (including PE) and PR changed tasks
> The left tasks are the ones that the "Dependencies" changed tasks
- When "-v" is specified:
> Figure out the newly added tasks
> Use bb.siggen.compare_sigfiles to figure out the details
* Output, for example (core-image-sato with different git tags)
and with recipes upgraded):
- without "-v":
Figuring out the STAMPS_DIR ...
Generating the new stamps ... (need several minutes)
=== Newly added tasks: (5 tasks)

* TODO
- It seems that the "bitbake -S core-image-sato" has bugs, it would always
report errors, but doesn't fatal errors
- The gcc-cross' stamps are in tmp/stamps/work-shared, but the
"bitbake -S" doesn't put the stamps in work-shared.
- The "bitbake -S" always generates the sigdata for image recipe's do_compile,
do_install and other tasks, we may need fix this from "bitbake -S".
- Print the ones which can be installed from the sstate.
