When handling section names in quotes obj_elf_section_name calls demand_copy_C_string, which puts the name on the gas notes obstack. Such strings aren't usually freed, since obstack_free frees all more recently allocated objects as well as its arg. When handling non-quoted names, obj_elf_section_name mallocs the name. Due to the mix of allocation strategies it isn't possible for callers to free names, if that was desirable. Partially fix this by always creating names on the obstack, which is more efficient anyway. (You still can't obstack_free on error paths due to the xtensa tc_canonicalize_section_name.) Also remove a couple of cases where the name is dup'd for no good reason as far as I know. PR 29256 * config/obj-elf.c (obj_elf_section_name): Create name on notes obstack. (obj_elf_attach_to_group): Don't strdup group name. (obj_elf_section): Likewise. (obj_elf_vendor_attribute): Use xmemdup0 rather than xstrndup.
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.
