2016-04-20Check R_386_NONE/R_X86_64_NONE in eh6.dH.J. Lu2-1/+10
There is no need for run-time relocation when converting pointers in .eh_frame section to DW_EH_PE_pcrel encoding. R_386_NONE and R_X86_64_NONE are expected since the space for run-time relocation has been allocated. This is an optimization.

2016-04-20[AArch64] Support RAS extension for ARMv8 onwards.Matthew Wahab8-0/+249
The RAS extension was introduced as part of the ARMv8.2 architecture where it is a required feature. It is also available as an optional feature for ARMv8 and ARMv8.1. In binutils, the RAS extension is currently enabled by default for -march=armv8.2-a but is not available for -march=armv8 or -march=armv8.1-a. This patch adds the feature extension '+ras' to enable the RAS extension for ARMv8 and ARMv8.1, it is disabled by default. gas/ 2016-04-20 Matthew Wahab <matthew.wahab@arm.com> * config/tc-aarch64.c (aarch64_features): Add "ras". * doc/c-aarch64.texi (AArch64 Extensions): Add "ras". * testsuite/gas/aarch64/armv8-ras-1.d: New. * testsuite/gas/aarch64/armv8-ras-1.s: New. * testsuite/gas/aarch64/illegal-ras-1.d: New. * testsuite/gas/aarch64/illegal-ras-1.s: New.

2016-04-19Cast the pointer assigned to ss_sp to char *.John Baldwin2-1/+7
FreeBSD versions older than 11.0 use char * as the type of ss_sp in stack_t instead of the standards-defined void *. C++ allows a char * pointer to be converted to a void *, so it is safe to cast the return value of xmalloc to char * if ss_sp is either a char * or void *. Just always use the cast to char * since that is less ugly than having to add a special case. gdb/ChangeLog: * main.c (setup_alternate_signal_stack): Cast to char *.

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.
