2016-02-28Don't recursively look for a symbol in all imports of imported modules.Iain Buclaw5-5/+197
Given two or more modules that import each other's scope, the current symbol lookup routines would go round in circles looking through each import from each module, possibly checking the same module twice or more until all possible paths are marked as "searched". Given enough modules, this causes an exponential slowdown in time taken to find symbols that do exist, and infinite recursion when they don't. gdb/ChangeLog: * d-namespace.c (d_lookup_symbol_imports): Avoid recursive lookups from cyclic imports. gdb/testsuite/ChangeLog: * gdb.dlang/circular.c: New file. * gdb.dlang/circular.exp: New file.

2016-02-26Optimize x86 GOT32X/GOTPCRELX relocationsH.J. Lu92-122/+1320
R_386_GOT32X, R_X86_64_GOTPCRELX and R_X86_64_REX_GOTPCRELX relocations retrieve the symbol address via its GOT slot. If the symbol address is known at the link-time, we can use it directly by changing instruction encoding. Indirect branch can only be converted to PC relative direct branch. MOV can be changed to LEA or encoded differently with signed address. The subset of binary operations can be encoded only with signed address. If undefined weak symbol is resolved to zero link-time, we can use it as address. Zero addresss can't used with PC relative direct branch when PIC is true since the current PC is unknown. In 64-bit, 32-bit relocation for PC relatiave direct branch to zero may also overflow. If this optimization causes relocation overflow, --no-relax can be used to work around it. bfd/ PR ld/19609 * elf32-i386.c (elf_i386_convert_load): Convert to R_386_32 for load with locally bound symbols if PIC is false or there is no base register.

2016-02-26[x86] Resolve non-PIC undefweak symbols in executableH.J. Lu95-165/+1970
For i386 and x86-64, non-PIC references to undefined weak symbols are resolved without dynamic relocation when creating executable. Resolved undefined weak symbols are removed from the dynamic symbol table in executable. One exception is on i386, we need resolved undefined weak symbols in the dynamic symbol table in PIE if input relocatable files contain branchs without PLT so that we can branch to 0 with dynamic relocation in text section. This makes behaviors of dynamic executable and position independent executable predictable with mixed PIC and non-PIC references to undefined weak symbols. If all references to undefined weak symbols are PIC, dynamic relocations against undefined weak symbols will be generated in executable unless -z nodynamic-undefined-weak is passed to linker. bfd/ PR ld/19636 PR ld/19704 PR ld/19719 * elf32-i386.c (UNDEFINED_WEAK_RESOLVED_TO_ZERO): New.

2016-02-25gdbserver/s390: Enable high GPRs, VX, TDB with 31-bit gdbserver.Marcin Kościelnicki2-26/+96
Currently, 31-bit gdbserver doesn't support collecting/supplying high GPRs, VX registers, and TDB data. This is not much of a problem now, since machines that have them usually have a 64-bit gdbserver that can be used to debug 31-bit targets just fine. However, with fast tracepoints, it's not possible to use a 64-bit gdbserver with a 31-bit IPA (and thus a 31-bit target), so 31-bit gdbserver has to be used for 31-bit targets. Thus, this patch is needed to allow collecting high GPRs and VX registers on 31-bit targets via fast tracepoints. gdb/gdbserver/ChangeLog: * linux-s390-low.c (s390_num_regs_3264): Define on 31-bit too.

2016-02-25[PR gdb/13808] gdb.trace: Pass tdesc selected in gdbserver to IPA.Marcin Kościelnicki15-70/+298
If gdbserver and IPA are using different tdesc, they will disagree about 'R' trace packet size. This results in mangled traces. To make sure they pick the same tdesc, gdbserver pokes the tdesc (specified as an index in a target-specific list) into a global variable in IPA. In theory, IPA could find out the tdesc on its own, but that may be complex (in particular, I don't know how to tell whether we have LAST_BREAK on s390 without messing with ptrace), and we'd have to duplicate the logic. Tested on i386 and x86_64. On i386, it fixes two FAILs in ftrace.exp. On x86_64, these failures have been KFAILed - one of them works now, but the other now fails due to an unrelated reason (ugh). gdb/gdbserver/ChangeLog: PR gdb/13808 * Makefile.in: Add i386-*-linux-ipa.o and amd64-*-linux-ipa.o. * configure.srv: Ditto. * linux-aarch64-ipa.c (get_ipa_tdesc): New function.
