In commitdb4ab410deI rewrote OP_STORE handling to support writing near the end of a section. The rewrite had some bugs, fixed in commit3e02c4891d. However I wasn't entirely happy with the code writing the bitfield: - it doesn't support 64-bit fields with a bit offset, - the code is duplicated and inelegant, - the stack ought to be popped whenever seeing one of these relocs, even if the reloc can't be applied. This patch fixes all of the above. In addition, it is clear from the OP_STORE description in the ABI that a 64-bit field is encoded as 0 in r_size, so I've decoded that in alpha_ecoff_swap_reloc_in. The aborts there are not appropriate as they can be triggered by user input (fuzzed object files). Also, stack underflow wasn't checked in alpha_relocate_section. * coff-alpha.c (alpha_ecoff_swap_reloc_in): Replace aborts with asserts. Decode ALPHA_R_OP_STORE r_size of zero. (write_bit_field): New function. (alpha_ecoff_get_relocated_section_contents): Use it. (alpha_relocate_section): Here too. Catch stack underflow.
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.
