* Fix xtensa ld segfault when linking linux modulesMax Filippov2014-07-102-1/+7
| | | | | | | | | | | | | | | | | | | | | | is_inconsistent_linkonce_section makes an assumption that section name that starts with ".gnu.linkonce.prop." has one more dot in its suffix. However gas generates such section name by insertion of "prop." right after ".gnu.linkonce." part of the name of the original section. So, for section named ".gnu.linkonce.this_module" corresponding property section name does not satisfy the assumption. Such section names are common in linux modules. This bug was exposed by the patch "a35d5e8 Fix alignment for the first section frag on xtensa", that makes gas produce property section for each section that has ".align" directive in it.

* Don't call bfd_link_hash_table_freeAlan Modra2014-06-133-19/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Freeing the linker hash table is a royal pain. It can't be freed before the _bfd_write_contents call in bfd_close, because some target bfd_write_contents functions access the hash table. It can't be freed after bfd_close either, since bfd_alloc memory holding side data structures disappears (PR17047). Clearly the only place it can be freed is actually in bfd_close. This patch doesn't do that, but kills off the existing means of freeing the hash table via a bfd target xvec call. bfd/ PR 17047 * targets.c (BFD_JUMP_TABLE): Delete NAME##_bfd_link_hash_table_free.

* Make it easy to make --disable-werror the default for both binutils and gdbJoel Brobecker2014-06-054-6/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The goal of this patch is to provide an easy way to make --disable-werror the default when building binutils, or the parts of binutils that need to get built when building GDB. In development mode, we want to continue making -Werror the default with GCC. But, when making releases, I think we want to make it as easy as possible for regular users to successfully build from sources. GDB already has this kind of feature to turn -Werror as well as the use of the libmcheck library. As GDB Release Manager, I take advantage of it to turn those off after having cut the branch. I'd like to be able to do the same for the binutils bits. And perhaps Tristan will want to do the same for his releases too (not sure, binutils builders might be a little savvier than GDB builders). This patch introduces a new file, called development.sh, which just sets a variable called $development. In our development branches (Eg. "master"), it's set to true. But setting it to false would allow us to change the default behavior of various development-related features to be turned off; in this case, it turns off the use of -Werror by default (use --enable-werror to turn it back on). bfd/ChangeLog: * development.sh: New file. * warning.m4 (AM_BINUTILS_WARNINGS): Source bfd/development.sh. Make -Werror the default with GCC only if DEVELOPMENT is true. * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add $(srcdir)/development.sh. * Makefile.in, configure: Regenerate. binutils/ChangeLog: * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add dependency on bfd's development.sh. * Makefile.in, configure: Regenerate. gas/ChangeLog: * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add dependency on bfd's development.sh. * Makefile.in, configure: Regenerate. gold/ChangeLog: * Makefile.am (CONFIG_STATUS_DEPENDENCIES): New. * Makefile.in, configure: Regenerate. gprof/ChangeLog: * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add dependency on bfd's development.sh. * Makefile.in, configure: Regenerate. ld/ChangeLog: * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add dependency on bfd's development.sh. * Makefile.in, configure: Regenerate. opcodes/ChangeLog: * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add dependency on bfd's development.sh. * Makefile.in, configure: Regenerate. gdb/ChangeLog: * development.sh: Delete. * Makefile.in (config.status): Adjust dependency on development.sh. * configure.ac: Adjust development.sh source call. * configure: Regenerate. gdb/gdbserver/ChangeLog: * configure.ac: Adjust development.sh source call. * Makefile.in (config.status): Adjust dependency on development.sh. * configure: Regenerate. Tested on x86_64-linux by building two ways: One with DEVELOPMENT set to true, and one with DEVELOPMENT set to false. In the first case, I could see the use of -Werror, while it disappeared in the second case.
