I noticed that the alignment of the .text and .data sections on
Solaris/x86 doesn't match what /bin/ld does: gld uses the original i386
psABI default of 0x1000, while Solaris has moved to larger values as can
be seen both in the Oracle Solaris 11.4 Linkers and Libraries Guide,
ch. 15, Program Loading and Dynamic Linking, p. 15-6 and the system
headers (<sys/elf_{i386,amd64}.h>) that have
while the Solaris/SPARC values are already correct.
To fix this, on i386 it's sufficient to redefine ELF_MAXPAGESIZE. On
x86_64, unlike i386, ELF_COMMONPAGESIZE is hardcoded as 0x1000, the
default, so setting ELF_MAXPAGESIZE has no effect on ELF_P_ALIGN.
Setting ELF_COMMONPAGESIZE to ELF_MAXPAGESIZE, too, fixes that and
brings both target in sync. ELF_MACHINE_CODE is just set to the original
value again, so it's removed.
Tested on {i386,amd64}-pc-solaris2.11, {i686,x86_64}-pc-linux-gnu, and
amd64-pc-freebsd14.0.

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
