Bug ID: 69179
Summary: undocumented darwin attributes
"apple_kext_compatibility" and "weak_import"
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: sandra at gcc dot gnu.org
Target Milestone: ---
config/darwin.c defines attributes "apple_kext_compatibility" and "weak_import"
which have no documentation in the GCC manual.
"apple_kext_compatibility" seems related to the also-undocumented -fapple-kext
command-line option (see PR 62273). Reading the code, I'm wondering if a
feature intended to provide backwards compatibility with GCC 2.95 is even
relevant to modern versions of Darwin, or whether this might be a candidate for
deletion as obsolete.
"weak_import" seems related to the normal "weak" attribute, but just from
reading the code I cannot figure out how to explain the difference in a concise
but user-friendly way.
Can a Darwin expert help fill in the missing docs?
