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.

2014-06-03This is to fix a further problem with merging resource sections. It turnsNick Clifton2-2/+36
out that the section is supposed to be page-aligned, but the newly merged section was not being padded out to a page boundary. This meant that when the executable was stripped a badly sized .rsrc section was written out. PR ld/16807 * peXXigen.c (rsrc_process_section): Page align the new contents befgore writing out.
2014-06-03Support fusion for ELFv2 stubsAlan Modra2-6/+21
Power8 fuses addis,addi and addis,ld sequences when the target of the addis is the same as the addi/ld. Thus addis r12,r2,xxx@ha addi r12,r12,xxx@l / ld r12,xxx@l(r12) is faster than addis r11,r2,xxx@ha addi r12,r11,xxx@l / ld r12,xxx@l(r11) So use the form that allows fusion in plt call and branch stubs. bfd/ * elf64-ppc.c (ADDIS_R12_R2): Define. (build_plt_stub): Support fusion on ELFv2 stub. (ppc_build_one_stub): Likewise for plt branch stubs. gold/ * powerpc.cc (addis_12_2): Define.

2014-05-20Rewrite ppc32 backend .sdata and .sdata2 handlingAlan Modra3-107/+133
1) _SDA_BASE_ and _SDA2_BASE_ and defined automatically, in a similar manner to the way _GLOBAL_OFFSET_TABLE_ is handled. It's a little more complicated to remove the symbols because _SDA_BASE_ needs to be there if either .sdata or .sbss is present, and similarly for _SDA2_BASE. 2) The linker created .sdata and .sdata2 sections used for R_PPC_EMB_SDAI16 and R_PPC_EMB_SDA2I16 pointers are created early. Nowadays we strip unneeded sections from the output, so it isn't necessary to delay creating the sections. 3) The output section for targets of various SDA relocs is now checked as per the ABI(s). We previously allowed .sdata.foo and similar, most likely because at some stage we were checking input sections. Also, the patch fixes a long-standing bug in size_input_sections that affects the values of symbols defined in stripped input sections. PR 16952 bfd/ * elf32-ppc.c (ppc_elf_create_linker_section): Move earlier. Remove redundant setting of htab->elf.dynobj. Don't align. Define .sdata symbols using _bfd_elf_define_linkage_sym.
