2018-08-31Set TYPE_LENGTH on a variant partTom Tromey2-0/+17
gdb represents a DW_TAG_variant_part as a union. While normally DWARF would not set the size of a DW_TAG_variant_part, gdb's representation requires the TYPE_LENGTH to be set. This patch arranges to set the TYPE_LENGTH of a variant part if it has not already been set. This fixes some Rust regressions when testing against a version of rustc that emits DW_TAG_variant_part. gdb/ChangeLog 2018-08-31 Tom Tromey <tom@tromey.com> * dwarf2read.c (dwarf2_add_field): Set the TYPE_LENGTH of the variant part type.
2018-08-31Fix a small bug in gdb.rust/simple.rsTom Tromey2-1/+5
I noticed that gdb.rust/simple.rs had two local variables named "v". This didn't previous cause problems, but with a newer rust compiler this resulted in a test failure. (It should have failed all along, so I suppose earlier passes were due to a compiler bug.) This patch renames the second variable. gdb/testsuite/ChangeLog 2018-08-31 Tom Tromey <tom@tromey.com> * gdb.rust/simple.rs: Rename second variable "v".
2018-08-31Regenerate gdbarch.hPedro Alves2-1/+6
The previous commit included a stale gdbarch.h from an earlier version of that patch by mistake. gdb/ChangeLog: 2018-08-31 Pedro Alves <palves@redhat.com> * gdbarch.h: Regenerate.
2018-08-31Add comment describing continuable/steppable/non-steppable watchpointsPedro Alves4-0/+45

2018-08-31Eliminate target_have_continuable_watchpointPedro Alves6-45/+11
target_have_continuable_watchpoint isn't used anywhere so remove it. The property isn't necessary because checking for "continuable" is the same as checking for "!steppable && !non-steppable". gdb/ChangeLog: 2018-08-31 Pedro Alves <palves@redhat.com> * nto-procfs.c (nto_procfs_target::have_continuable_watchpoint): Delete. * s390-linux-nat.c (s390_linux_nat_target::have_continuable_watchpoint): Delete. * target.h (target_ops::have_continuable_watchpoint): Delete.

2018-08-31ld: Lookup section in output with the same nameH.J. Lu6-0/+88
When there are more than one input sections with the same section name, SECNAME, linker picks the first one to define __start_SECNAME and __stop_SECNAME symbols. When the first input section is removed by comdat group, we need to check if there is still an output section with section name SECNAME.

2018-08-31Update gnulib/Makefile.in:aclocal_m4_depsSergio Durigan Junior2-32/+128
It was pointed by Pedro that gnulib/Makefile.in should be updated accordingly after our local gnulib is also updated. The specific part that needs to be refreshed is the "aclocal_m4_deps" variable, which lists the .m4 files present under the "gnulib/import/m4/" directory. This patch does that. No regressions introduced. gdb/ChangeLog: 2018-08-31 Sergio Durigan Junior <sergiodj@redhat.com> * gnulib/Makefile.in (aclocal_m4_deps): Update according to the files present in "gnulib/import/m4/".
2018-08-31PowerPC64 --emit-relocs support for notoc stubsAlan Modra2-37/+198
This patch uses the newly defined high-part REL16 relocs to emit relocations on the notoc stubs as we already do for other stubs. * elf64-ppc.c (num_relocs_for_offset): New function. (emit_relocs_for_offset): New function. (use_global_in_relocs): New function, split out from.. (ppc_build_one_stub): ..here. Output relocations for notoc stubs. (ppc_size_one_stub): Calculate reloc count for notoc stubs. (ppc64_elf_size_stubs): Don't count undefined syms in stub_globals.
2018-08-31PowerPC64 higher REL16 relocationsAlan Modra10-18/+150
There are occasions where someone might want to build a 64-bit pc-relative offset from 16-bit pieces. This adds the necessary REL16 relocs corresponding to existing ADDR16 relocs that can be used to build 64-bit absolute values. include/ * elf/ppc64.h (R_PPC64_REL16_HIGH, R_PPC64_REL16_HIGHA), (R_PPC64_REL16_HIGHER, R_PPC64_REL16_HIGHERA), (R_PPC64_REL16_HIGHEST, R_PPC64_REL16_HIGHESTA): Define.

2018-08-31Rearrange ppc_size_one_stub and correct _notoc stub examplesAlan Modra2-230/+286
This patch rearranges ppc_size_one_stub to make it a little easier to compare against ppc_build_one_stub, and makes a few other random changes that might help for future maintenance. There should be no functional changes here. The patch also fixes code examples in comments. A couple of "ori" instructions lacked the source register operand, and "@high" is the correct reloc modifier to use in a sequence building a 64-bit value. (@hi reports overflow of a 32-bit signed value.) * elf64-ppc.c: Correct _notoc stub comments. (ppc_build_one_stub): Simplify output of branch for notoc long branch stub. Don't include label offset of 8 bytes in "off" calculation for notoc plt stub. Don't emit insns to get pc. (build_offset): Emit insns to get pc here instead. (size_offset): Add 4 extra insns. (plt_stub_size): Adjust for "off" and size_offset changes. (ppc_size_one_stub): Rearrange code into a switch, duplicating some to better match ppc_build_one_stub.

2018-08-30gdb/riscv: remove extra caching of misa registerAndrew Burgess2-101/+15
The RISC-V had a mechanism in place to cache the contents of the misa register per-inferior, the original intention behind this was to reduce the number of times the misa register had to be read (as the contents should be constant), but it was pointed out on the mailing list[1] that the register cache will mean the register is only accessed once each time GDB stops, and any additional caching is probably just unneeded extra complexity. As such, until it can be shown that there's a real need for additional caching, this commit removes all of the additional caching of the misa register, and just accesses the misa register like a normal register.

2018-08-30gdb: Ensure compiler doesn't optimise variable out in testAndrew Burgess2-0/+14
In the test gdb.base/funcargs.exp, there's this function: void recurse (SVAL a, int depth) { a.s = a.i = a.l = --depth; if (depth == 0) hitbottom (); else recurse (a, depth); } The test script places a breakpoint in hitbottom, and runs the executable which calls recurse with an initial depth of 4. When GDB hits the breakpoint in hitbottom the testscript performs a backtrace, and examines 'a' at each level. The problem is that 'a' is not live after either the call to 'hitbottom' or the call to 'recurse', and as a result the test fails. In the particular case I was looking at GCC for RISC-V 32-bit, the variable 'a' is on the stack and GCC selects the register $ra (the return address register) to hold the pointer to 'a'. This is fine, because, by the time the $ra register is needed to hold a return address (calling hitbottom or recurse) then 'a' is dead. In this patch I propose that a use of 'a' is added after the calls to hitbottom and recurse, this should cause the compiler to keep 'a' around, which should ensure GDB can find it. gdb/testsuite/ChangeLog: * gdb.base/funcargs.c (use_a): New function. (recurse): Call use_a.

2018-08-29C++ compile supportKeith Seitz38-30/+4449
This patch adds *basic* support for C++ to the compile feature. It does most simple type conversions, including everything that C compile does and your basic "with-classes" type of C++. I've written a new compile-support.exp support file which adds a new test facility for automating and simplifying "compile print" vs "compile code" testing. See testsuite/lib/compile-support.exp and CompileExpression for more on that. The tests use this facility extensively. This initial support has several glaring omissions: - No template support at all I have follow-on patches for this, but they add much complexity to this "basic" support. Consequently, they will be submitted separately. - Cannot print functions The code template needs tweaking, and I simply haven't gotten to it yet. - So-called "special function" support is not included Using constructors, destructors, operators, etc will not work. I have follow-on patches for that, but they require some work because of the recent churn in symbol searching. - There are several test suite references to "compile/1234" bugs. I will file bugs and update the test suite's bug references before pushing these patches. The test suite started as a copy of the original C-language support, but I have written tests to exercise the basic functionality of the plug-in. I've added a new option for outputting debug messages for C++ type-conversion ("debug compile-cplus-types"). gdb/ChangeLog: * Makefile.in (SUBDIR_GCC_COMPILE_SRCS): Add compile-cplus-symbols.c and compile-cplus-types.c.

2018-08-29Update gnulib to current upstream masterSergio Durigan Junior317-8028/+12466
It has been a while since we don't update our gnulib copy against their upstream master branch, so I thought I'd propose this patch. It also fixes (at least) one bug reported against GDB: https://sourceware.org/bugzilla/show_bug.cgi?id=23558 The problem reported there is about the replacement of 'getcwd' when cross-compiling GDB. With our current gnulib copy, the mechanism for deciding whether to use the system's 'getcwd' or gnulib's version is too simplistic and pessimistic, so when cross-compiling we always end up using gnulib's version, which has a limitation: it cannot handle the situation when the parent directory doesn't have read permissions. This has been reported against upstream gnulib and the fix has been pushed here: https://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=a96d2e67052c879b1bcc5bc461722beac75fc372 I regtested this patch on Fedora 28 x86-64, and there were no regressions.
