2016-04-19Re-factor (i386|amd64)mpx target descriptions.Walfred Tedeschi13-132/+39
In the previous patch a new set of target descriptions (i386|amd64)-avx-mpx were added being same as the (i386|amd64)-mpx. This patch removes AVX feature from (i386|amd64)-mpx target description set. This way the (i386|amd64)avx_mpx(_linux|) set has AVX and MPX features and (i386|amd64)mpx(_linux|) only MPX. 2016-04-14 Walfred Tedeschi <walfred.tedeschi@intel.com> * features/i386/amd64-mpx-linux.xml: Remove AVX feature. * features/i386/amd64-mpx.xml: Remove AVX feature. * features/i386/i386-mpx-linux.xml: Remove AVX feature. * features/i386/i386-mpx.xml: Remove AVX feature. * features/i386/amd64-mpx-linux.c: Regenerate. * features/i386/amd64-mpx.c: Regenerate. * features/i386/i386-mpx-linux.c: Regenerate. * features/i386/i386-mpx.c: Regenerate. * regformats/i386/amd64-mpx-linux.dat: Regenerate. * regformats/i386/amd64-mpx.dat: Regenerate. * regformats/i386/i386-mpx-linux.dat: Regenerate. * regformats/i386/i386-mpx.dat: Regenerate.
2016-04-19Add target descriptions for AVX + MPXWalfred Tedeschi29-13/+1325
The current MPX target descriptions assume that MPX is always combined with AVX, however that's not correct. We can have machines with MPX and without AVX; or machines with AVX and without MPX. This patch adds new target descriptions for machines that support both MPX and AVX, as duplicates of the existing MPX descriptions. The following commit will remove AVX from the MPX-only descriptions. 2016-04-16 Walfred Tedeschi <walfred.tedeschi@intel.com> gdb/ChangeLog: * amd64-linux-tdep.c (features/i386/amd64-avx-mpx-linux.c): New include.

2016-04-18Fix PR gdb/19250: ptrace prototype is not detected properly in C++ modePedro Alves5-154/+23
The ptrace args/return types detection doesn't work properly in C++ mode, on non-GNU/Linux hosts. For example, on gcc70 (NetBSD 5.1), where the prototype is: int ptrace(int, __pid_t, void*, int); configure misdetects it as: $ grep PTRACE_TYPE config.h #define PTRACE_TYPE_ARG1 int #define PTRACE_TYPE_ARG3 int * #define PTRACE_TYPE_ARG4 int /* #undef PTRACE_TYPE_ARG5 */ #define PTRACE_TYPE_RET int resulting in: ../../src/gdb/amd64bsd-nat.c: In function 'void amd64bsd_fetch_inferior_registers(target_ops*, regcache*, int)': ../../src/gdb/amd64bsd-nat.c:56: warning: dereferencing type-punned pointer will break strict-aliasing rules ../../src/gdb/amd64bsd-nat.c: In function 'void amd64bsd_store_inferior_registers(target_ops*, regcache*, int)': ../../src/gdb/amd64bsd-nat.c:104: warning: dereferencing type-punned pointer will break strict-aliasing rules ../../src/gdb/amd64bsd-nat.c:110: warning: dereferencing type-punned pointer will break strict-aliasing rules We could address this [1], however despite ptrace.m4's claim: # Needs to be tested in C++ mode, to detect whether we need to cast # the first argument to enum __ptrace_request. it appears that there's actually no need to test in C++ mode. Always running the ptrace tests in C mode works just the same on GNU/Linux. I remember experimenting with several different ways to handle the original issue back then, and maybe that was needed in some other attempt and then I didn't realize it ended up not really necessary. Confirmed that this fixes the NetBSD 5.1 C++ build, and confirmed that C and C++ builds on Fedora 23 are unaffected.

2016-04-18Fix gdb crash when trying to print the address of a synthetic C++ referenceMartin Galvan4-4/+120
After compiling a program which uses C++ references some optimizations may convert the references into synthetic "pointers". Trying to print the address of one of such synthetic references causes gdb to crash with the following error: (gdb) print &ref /build/buildd/gdb-7.7.1/gdb/dwarf2loc.c:1624: internal-error: Should not be able to create a lazy value with an enclosing type A problem internal to GDB has been detected, further debugging may prove unreliable. Apparently, what was causing it was that value_addr returns a copy of the value that represents the reference with its type set to T* instead of T&. However, its enclosing_type is left untouched, which fails a check made in read_pieced_value. We only see the crash happen for references that are synthetic because they're treated as pieced values, thus the call to read_pieced_value. On a related note, it seems that in general there are all sorts of breakage when working with synthetic references.

2016-04-15remove pointless assignmentTrevor Saunders2-5/+8
Presumably this was supposed to be regname[sizeof (regname) - 1] but was typoed to regname[sizeof (rename) - 1]. However that should be unnecessary because sprintf should null terminate. As is this assignment is invalid ISO C because rename refers to the function rename (), and sizeof on functions is undefined. In GNU C C the size of functions is 1 so the expression is the same as regname[0]. The following call to sprintf () clearly will over right that, so the statement either has no effect or is invalid. Given that it seems safe to just remove it. While we are there correct the size of regname, and switch from snprintf to sprintf since we know the exact length of the result. gas/ChangeLog: 2016-04-15 Trevor Saunders <tbsaunde+binutils@tbsaunde.org> * config/tc-mips.c (md_begin): Remove useless assignment.

2016-04-14bfd/arc: Rename enum entries to avoid conflictsAndrew Burgess2-17/+25
In bfd/elf32-arc.c an enum is created that contains entries with generic names like 'NONE' and 'OFF'. This has been fine for now, but I had a need to include opcode/arc.h into bfd/elf32-arc.c. Unfortunately opcode/arc.h includes a different enum with identical generic names. Given that changing the enum in the header file could mean wide-ranging changes, while changing the enum in the .c file is limited to only changing the one file, I've added a prefix to the enum in the .c file. This commit does not add the new include, that will come later. There should be no functional change with this commit. bfd/ChangeLog: * elf32-arc.c (tls_got_entries): Add 'TLS_GOT_' prefix to all entries. (elf_arc_relocate_section): Update enum uses. (elf_arc_check_relocs): Likewise. (elf_arc_finish_dynamic_symbol): Likewise.

2016-04-13Test GDB connection to GDBserver with no symbol filesLuis Machado3-0/+124
This test exercises the scenarios where we attempt to connect GDB to GDBserver in standard remote mode, query the symbol file path, attempt to open said symbol file on GDB's end and fail, causing the connection to drop abruptly. Regression-tested on x86-64/Ubuntu. With an unpatched GDB we should see this: FAIL: gdb.server/connect-with-no-symbol-file.exp: sysroot=: action=permission: connection to GDBserver succeeded (the program is no longer running) FAIL: gdb.server/connect-with-no-symbol-file.exp: sysroot=: action=delete: connection to GDBserver succeeded (the program is no longer running) FAIL: gdb.server/connect-with-no-symbol-file.exp: sysroot=target:: action=permission: connection to GDBserver succeeded (the program is no longer running) FAIL: gdb.server/connect-with-no-symbol-file.exp: sysroot=target:: action=delete: connection to GDBserver succeeded (the program is no longer running) A patched GDB should have full passes. gdb/testsuite/ChangeLog: 2016-04-13 Luis Machado <lgustavo@codesourcery.com> * gdb.server/connect-with-no-symbol-file.c: New file. * gdb.server/connect-with-no-symbol-file.exp: New file.
2016-04-13Debugging without a binary (regression)Luis Machado2-2/+64
When we attempt to debug a process using GDBserver in standard remote mode without a symbol file on GDB's end, we may run into an issue where GDB cuts the connection attempt short due to an error. The error is caused by not being able to open a symbol file, like so: -- (gdb) set sysroot (gdb) tar rem :2345 Remote debugging using :2345 /proc/23769/exe: Permission denied. (gdb) i r The program has no registers now. (gdb) It should've been like this: (gdb) set sysroot (gdb) tar rem :2345 Remote debugging using :2345 warning: /tmp/symbol-file: Permission denied. 0xf7ddb2d0 in ?? () (gdb) i r eax 0x0 0 ecx 0x0 0 edx 0x0 0 ebx 0x0 0 esp 0xffffdfa0 0xffffdfa0 ebp 0x0 0x0 esi 0x0 0 edi 0x0 0 eip 0xf7ddb2d0 0xf7ddb2d0 eflags 0x200 [ IF ] cs 0x33 51 ss 0x2b 43 ds 0x0 0 es 0x0 0 fs 0x0 0 gs 0x0 0 (gdb) This is caused by a couple of function calls within exec_file_locate_attach that can potentially throw errors. The following patch guards both exec_file_attach and symbol_file_add_main to prevent the errors from disrupting the connection process. There was also a case where native GDB tripped on this problem, but it was mostly fixed by bf74e428bca61022bd5cdf6bf28789a184748b4d. Regression-tested on x86-64/Ubuntu. gdb/ChangeLog: 2016-04-13 Luis Machado <lgustavo@codesourcery.com> * exec.c (exec_file_locate_attach): Guard a couple functions that can throw errors.
