2016-04-20Move ELF relocation check after lang_gc_sectionsH.J. Lu3-14/+31
Move ELF relocation check after lang_gc_sections so that all the reference counting code for plt and got relocs can be removed. This only affects ELF targets which check relocations after opening all input file. * ldlang.c (lang_check_relocs): New function.

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.

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 *.

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.
