Section alignment for coff-go32 is inconsistent - The '.text' and '.data' sections are 16-byte aligned, but named sections '.text.*' and '.data.*' are only 4-byte aligned. '.gnu.linkonce.r.*' is aligned to 16 bytes, yet '.rodata' and '.rodata.*' are aligned to 4 bytes. For '.bss' all input sections are only aligned to 4 bytes. This primarily can cause trouble when using SSE instructions, which require their memory operands to be aligned to 16-byte boundaries. This patch solves the issue simply by setting the section alignment to 16 bytes, for all code and data sections referenced in the default linker script. * coff-go32.c (COFF_SECTION_ALIGNMENT_ENTRIES): Use partial name match for .text, .data. Add entries for .const, .rodata, .bss, .gnu.linkonce.b.
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.
