Re: RFC: Sort input section by list
Hi Arjan,
I suppose we chose differently; from a distro point of view patching
each app's code that big
is a no go for us; once the new binutils is released we can automate and
use the new feature
pretty quickly.
Add to this that which functions are on the list will also depend on
which arguments you pass to configure...
sorry but really the "just patch the code in 3000 places" is really not
going to work ;-(
Would you agree that if a using-currently-available-tools process could
be automated then it would be an acceptable solution to you ?
Lets assume that you have gotten to the stage where you have the
profiled list of functions in the order you wish them to appear in the
final binary. Lets also assume that you have compiled the sources with
-ffunction-sections. You could use a sed/awk script to convert the
function names into a linker script fragment that specifically
references each of the function sections by name. Then all you would
need is a slightly modified default linker script that INCLUDEs this
constructed fragment at the right place in the generic linker script.
Cheers
Nick
PS. For the record I am not saying that this feature cannot be added to
the linker. I am just trying to avoid feature bloat by seeing if your
problem can be solved by using the already existing features of the
compiler and linker.
