* Correct fabs and fneg insns in simulatorOleg Endo2014-11-282-3/+21
| | | | | | | | | | | | | | | | | | | | It seems that the implementation of the SH fabs and fneg insns in the simulator is not correct. They use the FP_UNARY macro which checks the FPSCR.PR setting and raises an exception if PR = 1 (double precision) and the register number is not even (i.e. a valid DF reg number). For normal unary FP insns this is fine. However, fneg and fabs perform the same (integer) operations regardless of the FPSCR.PR setting. This issue initially popped up here https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63260 I've checked some of the failing tests mentioned in GCC PR 63260 above with the patch applied and the failures go away. sim/sh/ChangeLog (tiny patch): * gencode.c (fabs, fneg): Implement as integer operation instead of using the FP_UNARY macro.
* Fix amd64 dwarf register number mapping (MMX register and higher)Pierre Muller2014-11-282-1/+13
| | | | | | | | | | | | | | | | | Dwarf register numbers are defined in "System V Application Binary Interface AMD64 Architecture Processor Supplement Draft Version 0.99.6" The amd64_dwarf_regmap array is missing the 8 MMX registers in Figure 3.36: DWARF Register Number Mapping page 57. This leads to a wrong value for the registers past this point. gdb/ChangeLog: Pushed by Joel Brobecker <brobecker@adacore.com>. * amd64-tdep.c (amd64_dwarf_regmap array): Add missing MMX registers. Tested on x86_64-linux.
* Remove (dead-code) native core file sniffers on Linux targetsUlrich Weigand2014-11-285-73/+11
| | | | | | | | | | | | | | | | | | | | | Since Andreas Arnez' recent patch series, all Linux targets install gdbarch_iterate_over_regset_sections routines. This means that on Linux native targets, old-style core sniffers are never used. Most Linux targets haven't been using such sniffers for a long time anyway, but a couple remain: ia64 and sparc use core-regset.o, and m68k installs its own core_fns. All this is now dead code, which this commit removes. gdb/ 2014-11-28 Ulrich Weigand  <uweigand@de.ibm.com> * config/ia64/linux.mh (NATDEPFILES): Remove core-regset.o. * config/sparc/linux.mh (NATDEPFILES): Likewise. * config/sparc/linux64.mh (NATDEPFILES): Likewise. * m68klinux-nat.c (fetch_core_registers): Remove.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We enable systemtap probe in glibc recently, and see the following gdb fail, (gdb) set solib-absolute-prefix /. ... Stopped due to shared library event:^M Inferior loaded /./foo/bar/gdb.base/break-probes-solib.so ... (gdb) FAIL: gdb.base/break-probes.exp: run til our library loads (the program exited) $binfile_lib is /foo/bar/gdb.base/break-probes-solib.so, but the sysroot is prefixed in solib.c:solib_find, as comments described: Global variable GDB_SYSROOT is used as a prefix directory to search for shared libraries if they have an absolute path. so the output becomes "/./foo/bar/gdb.base/break-probes-solib.so", which is still correct. However, the test repeatedly continue the program and tries to match $binfile_lib, finally, the program exits and the test fails. This patch is to adjust the pattern to match $sysroot$binfile_lib instead of $binfile_lib. gdb/testsuite: 2014-11-28 Yao Qi <yao@codesourcery.com> * gdb.base/break-probes.exp: Match library name prefixed with sysroot.

There needs to be more escaping of the square brackets. Currently, it is interpreted as "any one character from this big list of characters, followed by .*". When adding the required amount of backslashes, the test starts failing as it should. Moreover, both in Python 2.7 and Python 3.3 the numbers don't have the L suffix, so now the test fails because of that. Anybody knows why they were there in the first place? I just tested with Python 2.4 and there are no Ls. gdb/testsuite/ChangeLog: * gdb.python/py-linetable.exp: Escape properly sorted(fset) test expected output. Add parentheses for the call to print.

* Fix corrupted .eh_frame section with LTO and --gc-sections.Cary Coutant2014-11-253-6/+30
| | | | | | | | | | | | | | | | When --gc-sections is turned on during an LTO link, the .eh_frame sections from deferred files are processed before those from the replacement files. As a result, the section end-cap from crtendS.o is placed ahead of the .eh_frame data from the replacement files. This patch fixes the bug by skipping the layout of the deferred sections during GC pass 2. gold/ PR gold/17639 * object.cc (Sized_relobj_file): Initialize is_deferred_layout_.

* Fix trampolines search code for conditional branchesMax Filippov2014-11-265-4/+29
| | | | | | | | | | | | | | | | | | | | | | For conditional branches that need more than one trampoline to reach its target assembler couldn't always find suitable trampoline because post-loop condition check was placed inside the loop, resulting in premature loop termination. Move check outside the loop. This fixes the following build errors seen when assembling huge files produced by gcc: Error: jump target out of range; no usable trampoline found Error: operand 1 of 'j' has out of range value '307307' 2014-11-25 Max Filippov <jcmvbkbc@gmail.com> gas/ * config/tc-xtensa.c (search_trampolines): Move post-loop condition check outside the search loop. gas/testsuite/ * gas/xtensa/trampoline.d: Add expected output for branches. * gas/xtensa/trampoline.s: Add test case for branches.

* Optimize out i386/x86-64 JUMP_SLOT relocationH.J. Lu2014-11-2512-69/+543
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When there are both PLT and GOT references to the same function symbol, linker will create a GOTPLT slot for PLT entry and a GOT slot for GOT reference. A run-time JUMP_SLOT relocation is created to update the GOTPLT slot and a run-time GLOB_DAT relocation is created to update the GOT slot. Both JUMP_SLOT and GLOB_DAT relocations will apply the same symbol value to GOTPLT and GOT slots, respectively, at run-time. This optimization combines GOTPLT and GOT slots into a single GOT slot and removes the run-time JUMP_SLOT relocation. It replaces the regular PLT entry: indirect jump [GOTPLT slot] push relocation index jump PLT0 with an GOT PLT entry with an indirect jump via the GOT slot: indirect jump [GOT slot] nop and resolves PLT reference to the GOT PLT entry. We must avoid this optimization if pointer equality is needed since we don't clear symbol value in this case and the dynamic linker won't update the GOT slot. Otherwise, the resulting binary will get into an infinite loop at run-time. bfd/ * elf32-i386.c (elf_i386_got_plt_entry): New. (elf_i386_pic_got_plt_entry): Likewise.
