only do this for shared libraries.

A new ELF note with value 0x20 is added to signify that the crt code
no longer calls these methods so that rtld will know that it needs
to do it.  The name of the note section has been changed from
.note.ABI-tag to .note.tag.  There was an option to put the two notes
each in their own section, or put both notes in the same section.  The
latter was selected.  Since the second note is not an ABI-tag, the
section was simply renamed.  This doesn't cause any issues.

6 years agortld: Add main object initialization and finalization
John Marino [Sat, 17 Mar 2012 18:52:17 +0000 (19:52 +0100)]
rtld: Add main object initialization and finalization

Since DragonFly's inception, crt1 has called _init and _fini functions of
the binary rather than leaving this task to the runtime linker.  Likely
this was done in order to use the same crt code for both statically and
dynamically linked binaries.

When FreeBSD imported DragonFly's preinit, init, and fini array handling
code, they moved the _init and _fini calls to rtld.  In order for rtld to
maintain compatiblity with binaries created with crt code that call these
functions, rtld looks for an ELF note that indicates the binary was built
with a crt that does not call _init and _fini.

This commit imports this capability as well as synchronizes some of the
changes FreeBSD made to the DragonFly code.  Many of the differences
weren't necessary, but some represented improvements.  In any case, it
benefits both operating systems to minimize the differences between the
runtime linkers in order to continue to collaborate and share new

Taken from: FreeBSD SVN 232831 (2012-03-11)

One key difference between the DragonFly and FreeBSD implementations is
that FreeBSD will not properly execute a binary that requires
initialization and/or finalization if the PT_NOTE program header is
intentionally omitted using a custom linker script and the PHDRS
directive.  In the same case, DragonFly will look to see if the main
binary contains a gnu hash dynamic tag.  If it does, it assumes the binary
was built with the new crt, which is a very good assumption.  Since gnu
hash was inserted by default into binaries only a week ago, there's only
a window of few days where this isn't true, and PT_NOTE-free binaries are
very rare.

rtld: Support DT_GNU_HASH (startup performance increase)

This is another "First BSD to get" feature that Linux and Solaris
had years ago.  Essentially DT_GNU_HASH is a GNU extension to the ELF
format that allows symbol searches much faster than the System V ABI
standard hash does.  Both versions of our binutils have the capability
of generating GNU hashes alongside of (or instead of) the SysV hash.

The benefit comes at the real-time link stage when the rtld is
searching the libraries for symbols.  For very large programs
written in languages such as c++ that tend to link in many libraries
with many symbols, the reduction in start-time can be dramatic.

According to benchmarks done by binutils team in 2006, more than 90% of
the symbol queries of OpenOffice Writer are rejected by the Bloom filter
before the string comparison takes place:
