Bug ID: 62273
Summary: doc: Invoke.texi -mkernel mentions undocumented option
Product: gcc
Version: 4.7.4
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: joel at gcc dot gnu.org
As best I can tell, this is broken in every version from the tail of the
4.7-branch to the head today.
-mkernel is documented as:
Enable kernel development mode. The '-mkernel' option sets
'-static', '-fno-common', '-fno-cxa-atexit', '-fno-exceptions',
'-fno-non-call-exceptions', '-fapple-kext', '-fno-weak' and
'-fno-rtti' where applicable. This mode also sets '-mno-altivec',
'-msoft-float', '-fno-builtin' and '-mlong-branch' for PowerPC
targets.
Unfortunately, -fapple-kext does not appear anywhere in the manual. It is
listed in darwin.opt with this:
fapple-kext
Target Report C++ Var(flag_apple_kext)
Generate code for darwin loadable kernel extensions
I assume someone responsible for the Darwin configuration knows enough to add a
line or two of documentation.
