Re: RFC: Sort input section by list
Hi Arjan,
a customized linker script depends on which exact gcc is used.
it's also effectively impossible to use in an autoconf/automake/libtool
world.
While just putting in a file with a list of names is a ton easier for
the upstream or package developer.... while just keeping all the rest

But a linker script fragment would be OK, right ? (Since this
essentially what HJ is proposing).
What is the real purpose of this feature ? Ie do you know why it has
been requested ? The implication of the example you have given is
that the user wants to put certain name-mangled functions at the start
of the .text section, but why ?
because it allows the developer to put the commonly used functions at
the start of the file, improving density in the page cache for example,
> and generally improving startup time. (less pagefaults and less
TLB pressure)
But surely this could be done with gcc's section name function attribute
without requiring any alterations to the linker ?
Cheers
