2018-03-21S390: Enable re-attaching with native-extended-gdbserverAndreas Arnez2-44/+62
On s390x, when running attach.exp with native-extended-gdbserver, gdbserver crashes in find_regno like this: .../regcache.c:252: A problem internal to GDBserver has been detected. Unknown register tdb0 requested On the GDB side it looks like this: (gdb) attach 31568 Attaching to process 31568 Remote connection closed The test case attempts to attach to a new process via the already running gdbserver. Thus s390_arch_setup is called a second time, and that's where the problem occurs. In order to determine the word width (32 or 64 bits), s390_arch_setup reads the pswm register through the regcache. For that it uses a temporary tdesc which is supposed to work for all s390 targets, since the actual tdesc has not been determined yet. But in this second round this doesn't work, because s390_regsets has been updated already and now contains regsets not described by the temporary tdesc, such as the one containing tdb0. This is fixed by rearranging the logic in s390_arch_setup. gdb/gdbserver/ChangeLog: * linux-s390-low.c (s390_get_hwcap): Replace tdesc parameter by the word size. Add comment. (s390_get_wordsize): New function. (s390_arch_setup): No longer select a temporary tdesc to fetch the pswm with it. Instead, use s390_get_wordsize to determine the word size first and derive the correct tdesc from that directly.

2018-03-20Replace the linear search in find_pc_sect_line with a binary search.Stephen Roberts6-11/+216
This patch addresses slowness when setting breakpoints, especially in heavily templatized code. Profiling showed that find_pc_sect_line in symtab.c was the performance bottleneck. The original logic performed a linear search over ordered data. This patch uses a binary search, as suggested by comments around the function. There are no behavioural changes, but gdb is now faster at setting breakpoints in template code. Tested using on make check on an x86 target. The optimisation speeds up the included template-breakpoints.py performance test by a factor of 7 on my machine. ChangeLog: 2018-03-20 Stephen Roberts <stephen.roberts@arm.com> * gdb/symtab.c (find_pc_sect_line): now uses binary search. gdb/testsuite/ * gdb.perf/template-breakpoints.cc: New file. * gdb.perf/template-breakpoints.exp: New file. * gdb.perf/template-breakpoints.py: New file.
2018-03-20gc.exp: Remove extraneous LD flags from the personality testMaciej W. Rozycki2-1/+6
Complement commit 8988502d7534 ("MIPS/LD/testsuite: Correct dynamic links with VR4100, VR4300 and VR5000") and commit bf48520113c4 ("gc.exp: Fix a typo: $LFLAGS -> $LDFLAGS"), and remove extraneous additional LD flags explicitly passed to the personality test on invocation. This passing has accidentally leaked from a WIP version of the former change. With the actual version committed the $LDFLAGS global variable is used instead for `run_dump_test' to use implicitly, so that `-call_shared' precedes `-lpersonality' on the linker's command line, as otherwise a shared `libpersonality.so' library wouldn't be considered for linking, causing the test to fail. ld/ * testsuite/ld-gc/gc.exp: Remove extraneous LD flags from the personality test.

2018-03-19Support bare-identifier field initializers in RustTom Tromey5-0/+36
In Rust one can initialize a struct member from an identically-named local variable by simply mentioning the member name in the initializer, like: let x = 0; let y = Struct { x }; This initializes "Struct::x" from "x". This patch adds this form of initializer to the Rust expression parser and adds a test.

2018-03-19Convert observers to C++Tom Tromey86-1234/+999
This converts observers from using a special source-generating script to be plain C++. This version of the patch takes advantage of C++11 by using std::function and variadic templates; incorporates Pedro's patches; and renames the header file to "observable.h" (this change eliminates the need for a clean rebuild). Note that Pedro's patches used a template lambda in tui-hooks.c, but this failed to compile on some buildbot instances (presumably due to differing C++ versions); I replaced this with an ordinary template function.

2018-03-19Testsuite: Fix ambiguous "break" due to libinproctraceAndreas Arnez26-50/+79
Some of GDB's trace test cases define a function end() and place a breakpoint there with "break end". However, when libinproctrace is linked to the binary, there are multiple methods named "end", such as std::string::end() from the C++ library or format_pieces::end() from common/format.h. GDB then creates multiple breakpoints instead of just a single one, and some FAILs result, such as these: FAIL: gdb.trace/trace-mt.exp: ftrace on: break end FAIL: gdb.trace/trace-mt.exp: ftrace off: break end Fix this by adding the "-qualified" option to the break commands. For consistency, change all occurrences of "break end" (and similar) in all trace test cases, even if the current behavior does not cause problems. Also, consequently use the gdb_breakpoint convenience proc. gdb/testsuite/ChangeLog: * gdb.trace/actions-changed.exp: Call gdb_breakpoint with the "qualified" option when setting breakpoints. * gdb.trace/backtrace.exp: Likewise. * gdb.trace/circ.exp: Likewise. * gdb.trace/collection.exp: Likewise. * gdb.trace/disconnected-tracing.exp: Likewise. * gdb.trace/ftrace-lock.exp: Likewise. * gdb.trace/ftrace.exp: Likewise. * gdb.trace/infotrace.exp: Likewise. * gdb.trace/packetlen.exp: Likewise. * gdb.trace/passc-dyn.exp: Likewise. * gdb.trace/qtro.exp: Likewise. * gdb.trace/read-memory.exp: Likewise. * gdb.trace/report.exp: Likewise. * gdb.trace/signal.exp: Likewise. * gdb.trace/status-stop.exp: Likewise. * gdb.trace/strace.exp: Likewise. * gdb.trace/tfind.exp: Likewise. * gdb.trace/trace-break.exp: Likewise. * gdb.trace/trace-condition.exp: Likewise. * gdb.trace/trace-mt.exp: Likewise. * gdb.trace/tstatus.exp: Likewise. * gdb.trace/tsv.exp: Likewise. * gdb.trace/unavailable-dwarf-piece.exp: Likewise. * gdb.trace/unavailable.exp: Likewise. * gdb.trace/while-dyn.exp: Likewise.

2018-03-16Add silent Makefile rulesSimon Marchi9-57/+180
Many projects (e.g. the Linux kernel) and build systems use "silent" rules, which means that they'll only print a summary of what's being done instead of printing all the detailed command lines. While chatting on the #gdb IRC channel, I realized a few people (including me) thought it would be nice to have it in GDB too. The idea is that too much text is not useful, the important information gets lost. If there's only the essential information, it's more likely to be useful. Most of the time, when I look at the build output, it's to see how it's progressing. By just printing a brief summary of each operation, I can easily spot what's currently being compiled and therefore how the build progresses (with time you know the order in which files are compiled almost by heart). As with other projects (Linux, automake-based things, probably others), it's possible to print the complete command lines by passing V=1 to make (or any other non-zero value). I had one hesitation about this: when people report build failures, we are more likely to miss the full compile command line. We'll probably sometimes need to ask people to include the build log with "make V=1". I don't think it's a big downside, if other projects the size of the Linux kernel can live with it, I'm sure we can too. gdb/ChangeLog: * silent-rules.mk: New. * Makefile.in: Include silent-rules.mk (srcdir, VPATH, top_srcdir): Move up.

The solution is to pad before copying sfpr, so the copy is always at the end of stub_sec. * elf64-ppc.c (sfpr_define): Adjust for stub_sec size having sfpr size added before defining alias symbols. (ppc64_elf_build_stubs): Add stub section padding before copying sfpr contents and defining save/restore alias symbols.

2018-03-13Remove two cleanups using std::stringTom Tromey3-37/+26
This patches removes cleanups from a couple of spots by using std::string rather than manual memory management. Regression tested by the buildbot, though note that I don't believe the buildbot actually exercises the machoread code. gdb/ChangeLog 2018-03-13 Tom Tromey <tom@tromey.com> * machoread.c (macho_check_dsym): Change filenamep to a std::string*.
