2016-04-05ELF/LD: Avoid producing hidden and internal dynamic symbolsMaciej W. Rozycki19-11/+173
Always turn hidden and internal symbols which have a dynamic index into local ones. This is required by the the ELF gABI[1]: "A hidden symbol contained in a relocatable object must be either removed or converted to STB_LOCAL binding by the link-editor when the relocatable object is included in an executable file or shared object." "An internal symbol contained in a relocatable object must be either removed or converted to STB_LOCAL binding by the link-editor when the relocatable object is included in an executable file or shared object." The ELF linker usually respects this requirement, however in the case where a dynamic symbol has been preallocated due to a reference of the default export class aka visibility from the object being linked, and then merged with a hidden or internal symbol definition from within the same object, then the original export class is carried over to the output dynamic symbol table, because while merging the generic ELF linker only converts affected dynamic symbols to local when they are defined or referenced by the object being linked and a dynamic object involved in the link both at a time. The dynamic symbol produced confuses then the dynamic loader at the run time -- the hidden or internal export class is ignored and the symbol follows preemption rules as with the default export class. In the MIPS target it happens when `mips_elf_record_global_got_symbol' creates a dynamic symbol when a call relocation is encountered. Additionally if the undefined symbol referred by such a relocation does specify the intended export class, then a local dynamic symbol is created instead, which is harmless and allowed, but useless. Normally no local dynamic symbols are created, except for a single dummy one at the beginning. Correct the problem by removing the extra check for a dynamic symbol being defined or referenced by the object being linked and a dynamic object involved in the link both at a time. The test cases included cover the internal and hidden symbol cases, as well as a protected symbol for a reference, the handling of which is unchanged by this fix. Both cases described above are covered, that is where an internal or hidden dynamic symbol is produced and where a local one is. NB this change affects CRIS results where some symbols in the static table produced in a final link are now converted from STV_HIDDEN to STB_LOCAL. This happens whenever the `elf_backend_hide_symbol' handler is called, so the affected symbols must have been chosen for entering into the dynamic symbol table, except in these test cases no such symbol table is produced. In fully linked binaries the static symbol table is only used for debugging though, so such a change is fine.

2016-04-04gas/arc: Use #define from include/opcode/arc.hAndrew Burgess2-8/+7
In tc-arc.h we redefine constants that are also defined in the include/opcode/arc.h header file. The problem is that changing one without changing the other resulting in strange crashes. We could comment both locations to stress the importance of remembering to update the other location too, or we could just include the opcode/arc.h header file into the assembler. Given that other targets include their opcode/ARCH.h header file, and only having a single definition, where possible, is usually the safest solution, that's what I switch too with this commit. gas/ChangeLog: * config/tc-arc.h: Include 'opcode/arc.h'.

2016-03-31Fix PR gdb/19858: GDB doesn't register the JIT libraries on attachYichao Yu2-2/+20
Ref: https://sourceware.org/ml/gdb/2016-03/msg00023.html GDB currently fails to fetch the list of already-registered JIT modules on attach. Nothing is calling jit_inferior_init, which is what is responsible for walking the JIT object list at init time. Despite the misleading naming, jit_inferior_created_hook -> jit_inferior_init is only called when the inferior execs. This regressed with the fix for PR gdb/13431 (03bef283c2d3): https://sourceware.org/ml/gdb-patches/2012-02/msg00023.html which removed the inferior_created (jit_inferior_created_observer) observer. Adding an inferior_created observer back fixes the issue. In turn, this exposes a bug in jit_breakpoint_re_set_internal as well, which is returning the wrong result when we already have the breakpoint at the right address. gdb/ChangeLog: 2016-03-31 Yichao Yu <yyc1992@gmail.com> PR gdb/19858 * jit.c (jit_breakpoint_re_set_internal): Return 0 if we already got the breakpoint at the right address.

2016-03-31IPA: Add alloc_jump_pad_buffer target hook.Marcin Kościelnicki7-19/+194
Targets may have various requirements on the required location of the jump pad area. Currently IPA allocates it at the lowest possible address, so that it is reachable by branches from the executable. However, this fails on powerpc, which has executable link address (0x10000000) much larger than branch reach (+/- 32MiB). This makes jump pad buffer allocation a target hook instead. The current implementations are as follows: - i386 and s390: Branches can reach anywhere, so just mmap it. This avoids the linear search dance. - x86_64: Branches have +/-2GiB of reach, and executable is loaded low, so just call mmap with MAP_32BIT. Likewise avoids the linear search. - aarch64: Branches have +-128MiB of reach, executable loaded at 4MiB. Do a linear search from 4MiB-size downwards to page_size. - s390x: Branches have +-4GiB of reach, executable loaded at 2GiB. Do like on aarch64. gdb/gdbserver/ChangeLog: * linux-aarch64-ipa.c: Add <sys/mman.h> and <sys/auxv.h> includes. (alloc_jump_pad_buffer): New function. * linux-amd64-ipa.c: Add <sys/mman.h> include.
