2018-07-24Remove some unnecessary declarations and configuryTom Tromey5-53/+8
configure checks for declarations of free, malloc, and realloc; but the results are only used in a single spot: utils.c. I think these checks are long since obsolete, so this patch removes them. Grepping the entire tree for these HAVE_DECL_ symbols, the only uses of possible interest to gdb come from bfd/sysdep.h; but this is not (nor should be) included by gdb. (And furthermore I think the code there is probably also obsolete.) gdb/ChangeLog 2018-07-24 Tom Tromey <tom@tromey.com> * utils.c (malloc, realloc, free): Don't declare. * configure, config.in: Rebuild. * configure.ac: Don't check for declarations of free, malloc, or realloc.

2018-07-24x86-64: correct AVX512F vcvtsi2s{d,s} handlingJan Beulich15-404/+453
Just like for their AVX counterparts and CVTSI2S{D,S}, a memory source here is ambiguous and hence - in source files should be qualified with a suitable suffix or operand size specifier (not doing so is an error in Intel mode, and will gain a diagnostic in AT&T mode in the future), - in disassembly should be properly suffixed (the Intel operand size specifiers were emitted correctly already).

The function elf_xtensa_finish_dynamic_sections checks that sizes of sections .rela.dyn and .rela.plt match number of corresponding relocation records, but the check is only done when .rela.plt is non-empty, so, e.g. it is never run for the static PIE.

This removes a few unused variables from gdbserver. The x86-tdesc.h change is a bit unusual for this series. This file was not defining the multiple-include guard symbol, so I've added that here.

2018-07-21Initialize GOT slot for local symbol in non-PIC link.Eric Botcazou2-28/+45
On ARM/VxWorks 7, the R_ARM_TARGET2 relocation used for exception handling is R_ARM_GOT_PREL; moreover in Ada you can define local exceptions. In this case, you may end up with a GOT relocation against a local symbol in a non-PIC link and the ARM linker leaves the GOT slot uninitialized, unlike for example the i386 or the SPARC linkers in the same situation. bfd/ * elf32-arm.c (elf32_arm_final_link_relocate) <R_ARM_GOT32>: Small cleanup for the case of a global symbol that binds locally.

2018-07-20Rename some frame unwind function parametersSimon Marchi3-25/+41
I am currently working with these functions, and though this renaming could help to reason about the code. Some functions take a frame and will return the value associated to that frame, others will return the value associated to the previous frame. Those usually conveniently contain "unwind" in their name, but naming the variable next_frame instead of frame helps remembering which frame we are dealing with.

2018-07-20ld: Discard .rel.* and .rela.* sectionsH.J. Lu2-1/+6
On many targets, like x86, .rel.dyn/.rela.dyn section is combined from different .rel/.rela sections by -z combreloc. To discard dynamic relocation section, we need to discard .rel.* and .rela.* sections instead of .rel.dyn and .rela.dyn sections. Note: This test fails for targets which issue a warning when dynamic section is discarded. * testsuite/ld-elf/reloc-discard.ld: Discard .rel.* and .rela.* sections instead of .rel.dyn and .rela.dyn sections.
2018-07-20MIPS/Linux/native: Convert to `get_ptrace_pid' for PID extractionMaciej W. Rozycki2-5/+7
Use `get_ptrace_pid' to get the ptrace PID from `inferior_ptid' rather than extracting it by hand. gdb/ * mips-linux-nat.c (mips_linux_nat_target::read_description): Call `get_ptrace_pid' rather than extracting the ptrace PID by hand.
2018-07-20x86: Add a GNU_PROPERTY_X86_ISA_1_USED note if neededH.J. Lu20-25/+248
When -z separate-code, which is enabled by default for Linux/x86, is used to create executable, ld won't place any data in the code-only PT_LOAD segment. If there are no data sections placed before the code-only PT_LOAD segment, the program headers won't be mapped into any PT_LOAD segment. When the executable tries to access it (based on the program header address passed in AT_PHDR), it will lead to segfault. This patch inserts a GNU_PROPERTY_X86_ISA_1_USED note if there may be no data sections before the text section so that the first PT_LOAD segment won't be code-only and will contain the program header. Testcases are adjusted to either pass "-z noseparate-code" to ld or discard the .note.gnu.property section. A Linux/x86 run-time test is added. bfd/ PR ld/23428 * elfxx-x86.c (_bfd_x86_elf_link_setup_gnu_properties): If the separate code program header is needed, make sure that the first read-only PT_LOAD segment has no code by adding a GNU_PROPERTY_X86_ISA_1_USED note. ld/ PR ld/23428 * testsuite/ld-elf/linux-x86.S: New file. * testsuite/ld-elf/linux-x86.exp: Likewise. * testsuite/ld-elf/pr23428.c: Likewise. * testsuite/ld-elf/sec64k.exp: Pass "-z noseparate-code" to ld for Linux/x86 targets. * testsuite/ld-i386/abs-iamcu.d: Likewise. * testsuite/ld-i386/abs.d: Likewise. * testsuite/ld-i386/pr12718.d: Likewise. * testsuite/ld-i386/pr12921.d: Likewise. * testsuite/ld-x86-64/abs-k1om.d: Likewise. * testsuite/ld-x86-64/abs-l1om.d: Likewise. * testsuite/ld-x86-64/abs.d: Likewise. * testsuite/ld-x86-64/pr12718.d: Likewise. * testsuite/ld-x86-64/pr12921.d: Likewise. * testsuite/ld-linkonce/zeroeh.ld: Discard .note.gnu.property section. * testsuite/ld-scripts/print-memory-usage.t: Likewise. * testsuite/ld-scripts/size-2.t: Likewise. * testsuite/lib/ld-lib.exp (run_ld_link_exec_tests): Use ld to create executable if language is "asm".

This renames all the remaining members of buildsym_compunit to start with "m_" to follow the general naming convention. gdb/ChangeLog 2018-07-20 Keith Seitz <keiths@redhat.com> * buildsym.h (struct buildsym_compunit) <m_objfile, m_subfiles, m_main_subfile, m_comp_dir, m_producer, m_debugformat, m_compunit_symtab, m_language>: Add "m_" prefix. Update all uses. * buildsym.c: Update all uses.
2018-07-20Remove record_line_ftypeTom Tromey3-5/+6
The record_line_ftype typedef was only used in the DWARF reader, and we removed those uses a few patches ago. So, remove the typedef. gdb/ChangeLog 2018-07-20 Tom Tromey <tom@tromey.com> * buildsym-legacy.h (record_line): Don't use record_line_ftype. * buildsym.h (record_line_ftype): Remove typedef.
