binutils-gdb modified for the FreeChainXenon project
![]() Hi, I build GDB with -fsanitize=address, and run testsuite. In gdb.base/callfuncs.exp, I see the following error, p/c fun1() =================================================================^M ==9601==ERROR: AddressSanitizer: stack-buffer-overflow on address 0x7fffee858530 at pc 0x6df079 bp 0x7fffee8583a0 sp 0x7fffee858398 WRITE of size 16 at 0x7fffee858530 thread T0 #0 0x6df078 in regcache_raw_read /home/yao/SourceCode/gnu/gdb/git/gdb/regcache.c:673 #1 0x6dfe1e in regcache_cooked_read /home/yao/SourceCode/gnu/gdb/git/gdb/regcache.c:751 #2 0x4696a3 in aarch64_extract_return_value /home/yao/SourceCode/gnu/gdb/git/gdb/aarch64-tdep.c:1708 #3 0x46ae57 in aarch64_return_value /home/yao/SourceCode/gnu/gdb/git/gdb/aarch64-tdep.c:1918 We are extracting return value from V registers (128 bit), but only allocate X_REGISTER_SIZE-byte array, which isn't sufficient. This patch changes the array to V_REGISTER_SIZE. gdb: 2015-11-16 Yao Qi <yao.qi@linaro.org> * aarch64-tdep.c (aarch64_extract_return_value): Change array buf's length to V_REGISTER_SIZE. |

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.
