"""Correct the shebang at the top of a scatter file.
The shebang line is the line at the top of the file starting with '#!'. If this line is present
then the linker will execute the command on that line on the content of the scatter file prior
to consuming the content into the link. Typically the shebang line will contain an instruction
to run the C-preprocessor (either 'armcc -E' or 'armclang -E') which allows for macro expansion,
inclusion of headers etc. Other options are passed to the preprocessor to specify aspects of the
system such as the processor architecture and cpu type.
The build system (at this point) will have constructed what it considers to be a correct shebang
line for this build. If this differs from the line in the scatter file then the scatter file
will be rewritten by this function to contain the build-system-generated shebang line. Note
that the rewritten file will be placed in the BUILD output directory.
Include processing
If the scatter file runs the preprocessor, and contains #include statements then the pre-processor
include path specifies where the #include files are to be found. Typically, #include files
are specified with a path relative to the location of the original scatter file. When the
preprocessor runs, the system automatically passes the location of the scatter file into the
include path through an implicit '-I' option to the preprocessor, and this works fine in the
offline build system.
Unfortunately this approach does not work in the online build, because the preprocessor
command runs in a chroot. The true (non-chroot) path to the file as known by the build system
looks something like this:
/tmp/chroots/ch-eefd72fb-2bcb-4e99-9043-573d016618bb/extras/mbed-os.lib/...
whereas the path known by the preprocessor will be:
/extras/mbed-os.lib/...
Consequently, the chroot path has to be explicitly passed to the preprocessor through an
explicit -I/path/to/chroot/file option in the shebang line.
*** THERE IS AN ASSUMPTION THAT THE CHROOT PATH IS THE REAL FILE PATH WITH THE FIRST
*** THREE ELEMENTS REMOVED. THIS ONLY HOLDS TRUE UNTIL THE ONLINE BUILD SYSTEM CHANGES
If the include path manipulation as described above does change, then any scatter file
containing a #include statement is likely to fail on the online compiler.
Positional arguments:
sc_fileref -- FileRef object of the scatter file
Keyword arguments:
cur_dir_name -- the name (not path) of the directory containing the
scatter file
Return:
The FileRef of the correct scatter file
Side Effects:
This method MAY write a new scatter file to disk
