binutils-gdb modified for the FreeChainXenon project
![]() This is the 32-bit companion to Remove unused ps_lgetLDT etc. on Solaris/x86 [PR25981] https://sourceware.org/pipermail/gdb-patches/2020-May/168713.html A 32-bit-default gdb fails to compile with the updated <sys/regset.h>. While it is also affected by the lack of a GS definition, which the compantion patch above fixes, it also fails to compile i386-sol2-nat.c like this /vol/src/gnu/gdb/hg/master/git/gdb/i386-sol2-nat.c:181:3: error: 'EAX' was not declared in this scope 181 | EAX, ECX, EDX, EBX, | ^~~ and several more. While this could be fixed by either including <ucontext.h> here or provding fallback definitions of the register macros, I chose to do what the 64-bit-default code in the same file (amd64_sol2_gregset32_reg_offset[]) does, namely just hardcode the numeric values instead. They are part of the ABI and thus guaranteed not to change. With this patch, a i386-pc-solaris2.11 configuration on master compiles again, however, it doesn't work. However, I could successfully test it on the gdb-9 branch. Compiling and testing proved to be messy, unfortunately: * For one, Solaris <sys/procfs.h> and largefile support used to be mutually exclusive (fixed in Solaris 11.4 and Illumos), which was exacerbated by the fact that g++ predefines _FILE_OFFSET_BITS=64 since GCC 9.1.0. For now I've worked around this by adding -U_FILE_OFFSET_BITS to CXXFLAGS and configuring with --disable-largefile. I hope to clean this up in a future patch. * gdb still defaults to startup-with-shell on. However, /bin/bash is a 64-bit executable which cannot be debugged by a 32-bit gdb. I hacked around that part by pointing $SHELL at a 32-bit bash before running make check. PR build/25981 * i386-sol2-nat.c [PR_MODEL_NATIVE != PR_MODEL_LP64] (regmap): Hardcode register numbers. |

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.
