This is more consistent with the names used for .ctor and .dtor
symbols and better reflects __JCR_END__'s role.

Include ABI note tag in shared libraries.2020-07-16T21:58:43ZJohn Baldwinjhb@FreeBSD.org2020-07-16T21:58:43Zurn:sha1:0bfad4329818423960a75ed0a305005098e237ac
Split the ELF feature note into a separate file that is linked into
*crt1.o the same as crtbrand.S was before. crtbrand.o is now linked
into crti.o on all platforms in addition to *crt1.o.

Remove the sed hack for ABI tag notes.2020-06-15T19:38:48ZJohn Baldwinjhb@FreeBSD.org2020-06-15T19:38:48Zurn:sha1:99282790b7d01ec3c4072621d46a0d7302517ad4
The ELF notes compiled in C were placed in a section with the wrong type
(SHT_PROGBITS instead of SHT_NOTE). Previously, sed was used on the
generated assembly to rewrite the section type. Instead, write the notes
in assembly which permits setting the correct section type directly.
While here, move inline assembly entry points out of C and into assembly
for aarch64, arm, and riscv.

csu: Fix dynamiclib/init_test:jcr_test on !HAVE_CTORS archs2019-11-08T14:28:39ZKyle Evanskevans@FreeBSD.org2019-11-08T14:28:39Zurn:sha1:20cb0deaa2db72f198b0574dc22401a548d6c56b
.jcr still needs a 0-entry added in crtend, even on !HAVE_CTORS archs, as
we're still getting .jcr sections added -- presumably due to the reference
in crtbegin. Without this terminal, the .jcr section (without data) overlaps
with the next section and register_classes in crtbegin will be examining the
wrong item.

Without this the dynamic library test was failing as it was calling
_Jv_RegisterClasses multiple times.

This note will be used to allow binaries to opt out of, or in to,
upcoming vulnerability mitigation and other features. It is not yet
connected but being added now to facilitate testing and ensure
compatibility with existing kernels and tools.

Add __used to __CTOR_LIST__ and __DTOR_LIST__2018-10-31T14:19:58ZEd Masteemaste@FreeBSD.org2018-10-31T14:19:58Zurn:sha1:57706376c63d433935dbadcbee514c6eb7a395cd
Enabling BSD_CRTBEGIN on amd64 resulted in
error: unused variable '__CTOR_LIST__'.
__CTOR_LIST__ is indeed unused in crtbegin.c; it marks the beginning of
the .ctors array and is used in crtend.c. Annotate __DTOR_LIST__ as
well for consistency.
