This fixes an error message given too eagerly on ppc64le,
|
||
|
|
when no input files are used and as-needed is in effect. E.g.:
|
||
|
|
|
||
|
|
% ld-new --as-needed -o /dev/null -lc
|
||
|
|
|
||
|
|
gives an error message about input and output ABI versions being
|
||
|
|
incompatible. This is because the ABI setting of "unknown" (0)
|
||
|
|
to "from-input" is done in ppc64_elf_before_check_relocs, which
|
||
|
|
isn't called for as-needed libraries (via check_directives callback).
|
||
|
|
merge_private_bfd_data is called for as-needed and not-as-needed inputs
|
||
|
|
(via notice_as_needed), so copy that code there.
|
||
|
|
|
||
|
|
This construct is used in some packages to check for availability
|
||
|
|
of libraries (e.g. in nvme-cli to check for -luuid). Redircting error
|
||
|
|
output makes this siletently fail.
