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(${line}*)); " format, which in the linker parlance -# will allow it to trap all symbols relevant to the subsection. -# -define make_u_boot_list -$(1): $(2) - $(OBJDUMP) -h $(2) | \ - sed -n -e '/.*\.u_boot_list[^ ]\+/ ! {d;n}' \ - -e 's/.*\(\.u_boot_list[^ ]\+\).*$$$$/\1/' \ - -e 's/\.[^\.]\+$$$$//' \ - -e ':s /^.\+$$$$/ { p;s/^\(.*\)\.[^\.]*$$$$/\1/;b s }' | \ - sed -n -e 'h;s/$$$$/\a/p;g;s/$$$$/@/p;g;s/$$$$/~/p;' | \ - LC_COLLATE=C sort -u | \ - sed -n -e '/\a$$$$/ { s/\./_/g;s/\a$$$$/__start = .;/p; }'\ - -e '/~$$$$/ { s/\./_/g;s/~$$$$/__end = .;/p; }'\ - -e '/@$$$$/ { s/\(.*\)@$$$$/*(SORT(\1.*));/p }' > $(1) -endef |
