2014-06-16ld/ARM: Fix IFUNC and TLS descriptors in the same shared objectWill Newton2-3/+14
Combining TLS descriptors and GNU indirect functions in the same object could lead to assertions or multiple dynamic relocations for the same GOT slot. Fix the bookkeeping so this doesn't happen. This allows building and make checking glibc with -mtls-dialect=gnu2. bfd/ChangeLog: 2014-06-16 Will Newton <will.newton@linaro.org> * elf32-arm.c (elf32_arm_allocate_plt_entry): Increment htab->next_tls_desc_index in the non-IPLT case.

2014-06-13Don't call bfd_link_hash_table_freeAlan Modra51-92/+35
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.

2014-06-07Allow both signed and unsigned fields in PowerPC cmpli insnAlan Modra3-12/+20
There are legitimate reasons to allow a signed value in a cmpli insn field, for example to test for a "stw r1,lock@sdarel(r13)" instruction in user code, a kernel might use subis r3,r3,STW_R1_0R13@ha # subtract off high part cmplwi r3,lock@sdarel # is low part accessing lock?

2014-06-05Make it easy to make --disable-werror the default for both binutils and gdbJoel Brobecker6-6/+42
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.
