# make_u_boot_list - Generate contents of u_boot_list section
|
||
|
|
# 1: The name of the resulting file (usually u-boot.lst)
|
||
|
|
# 2: Files to analyze for possible u_boot_list entries
|
||
|
|
#
|
||
|
|
# This function generates the contents of the u_boot_list section,
|
||
|
|
# including all the border symbols for it's subsections. The operation
|
||
|
|
# of this function is as follows, numbering goes per lines:
|
||
|
|
#
|
||
|
|
# 1) Dump the ELF header sections from all files supplied via $(2)
|
||
|
|
# 2) Filter out all other stuff that does not belong into .u_boot_list
|
||
|
|
# section.
|
||
|
|
# 3) Fix up the lines so that the resulting output is is in format
|
||
|
|
# ".u_boot_list.*".
|
||
|
|
# 4) Remove the last .something$, since that only contains the name
|
||
|
|
# of the variable to be put into a subsection. This name is irelevant
|
||
|
|
# for generation of border symbols, thus of no interest, remove it.
|
||
|
|
# 5) Take each line and for every dot "." in that line, print the whole
|
||
|
|
# line until that dot "." . This is important so that we have all
|
||
|
|
# parent border symbols generated as well.
|
||
|
|
# 6) Load every line and firstly append "\a" at the end and print the
|
||
|
|
# line. Next, append "@" at the end and print the line. Finally,
|
||
|
|
# append "~" at the end of line. This will make sense in conjunction
|
||
|
|
# with 6) and 7).
|
||
|
|
# 7) Sort the lines. It is imperative to use LC_COLLATE=C here because
|
||
|
|
# with this, the "\a" symbol is first and "~" symbol is last. Any
|
||
|
|
# other symbols fall inbetween. Symbols like "@", which marks the
|
||
|
|
# end of current line (representing current section) and ".", which
|
||
|
|
# means the line continues and thus represents subsection.
|
||
|
|
# 8) With such ordering, all lines ending with "\a" will float at the
|
||
|
|
# begining of all lines with the same prefix. Thus it is easy to
|
||
|
|
# replace "\a" with __start and make it the __start border symbol.
|
||
|
|
# Very similarly for "~", which will be always at the bottom and so
|
||
|
|
# can be replaced by "__end" and made into the __end border symbol.
|
||
|
|
# Finally, every line ending with "@" symbol will be transformed
|
||
|
|
# into " *(SORT(${line}*)); " format, which in the linker parlance
|
||
|
|
# will allow it to trap all symbols relevant to the subsection.
