8 # @BLURB: functions to query common info about the toolchain
9 # @DESCRIPTION:
10 # The toolchain-funcs aims to provide a complete suite of functions
11 # for gleaning useful information about the toolchain and to simplify
12 # ugly things like cross-compiling and multilib. All of this is done
13 # in such a way that you can rely on the function always returning
14 # something sane.

527 /* GNU ld script
528 Since Gentoo has critical dynamic libraries in /lib, and the static versions
529 in /usr/lib, we need to have a "fake" dynamic lib in /usr/lib, otherwise we
530 run into linking problems. This "fake" dynamic lib is a linker script that
531 redirects the linker to the real lib. And yes, this works in the cross-
532 compiling scenario as the sysroot-ed linker will prepend the real path.

534 See bug http://bugs.gentoo.org/4411 for more info.

545 # This function is for AIX only.
546 #
547 # Showing a sample IMO is the best description:
548 #
549 # First, AIX has its own /usr/lib/libiconv.a containing 'shr.o' and 'shr4.o'.
550 # Both of them are shared-objects packed into an archive, thus /usr/lib/libiconv.a
551 # is a shared library (!), even it is called lib*.a.
552 # This is the default layout on aix for shared libraries.
553 # Read the ld(1) manpage for more information.
554 #
555 # But now, we want to install GNU libiconv (sys-libs/libiconv) both as
556 # shared and static library.
557 # AIX (since 4.3) can create shared libraries if '-brtl' or '-G' linker flags
558 # are used.
559 #
560 # Now assume we have GNU tar installed while GNU libiconv was not.
561 # This tar now has a runtime dependency on "libiconv.a(shr4.o)".
562 # With our ld-wrapper (from sys-devel/binutils-config) we add EPREFIX/usr/lib
563 # as linker path, thus it is recorded as loader path into the binary.
564 #
565 # When having libiconv.a (the static GNU libiconv) in prefix, the loader finds
566 # that one and claims that it does not contain an 'shr4.o' object file:
567 #
568 # Could not load program tar:
569 # Dependent module EPREFIX/usr/lib/libiconv.a(shr4.o) could not be loaded.
570 # Member shr4.o is not found in archive
571 #
572 # According to gcc's "host/target specific installation notes" for *-ibm-aix* [1],
573 # we can extract that 'shr4.o' from /usr/lib/libiconv.a, mark it as
574 # non-linkable, and include it in our new static library.
575 #
