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.

2018-03-08Change enable_thread_stack_temporaries to an RAII classTom Tromey5-84/+77
This started as a patch to change enable_thread_stack_temporaries to be an RAII class, but then I noticed that this code used a VEC, so I went ahead and did a bit more C++-ification, changing stack_temporaries_enabled to a bool and changing stack_temporaries to a std::vector. Regression tested by the buildbot. gdb/ChangeLog 2018-03-08 Tom Tromey <tom@tromey.com> * infcall.c (struct call_return_meta_info) <stack_temporaries_enabled>: Remove. (get_call_return_value, call_function_by_hand_dummy): Update. * thread.c (disable_thread_stack_temporaries): Remove. (enable_thread_stack_temporaries): Remove. (thread_stack_temporaries_enabled_p): Return bool. (push_thread_stack_temporary, value_in_thread_stack_temporaries) (get_last_thread_stack_temporary): Update. * eval.c (evaluate_subexp): Update. * gdbthread.h (class enable_thread_stack_temporaries): Now a class, not a function. (value_ptr, value_vec): Remove typedefs. (class thread_info) <stack_temporaries_enabled>: Now bool. <stack_temporaries>: Now a std::vector. (thread_stack_temporaries_enabled_p) (value_in_thread_stack_temporaries): Return bool.
2018-03-08x86: Optimize with EVEX128 encoding for AVX512VLH.J. Lu13-56/+459
We can optimize AVX512 instructions with EVEX128 only if AVX512VL is enabled: 1. Instruction is an AVX512VL instruction. Or 2. AVX512VL is enabled explicitly by -march=+avx512vl/".arch .avx512vl". We should optimize EVEX instructions with EVEX128 encoding when pseudo {evex} prefix is used. * config/tc-i386.c (set_cpu_arch): Set cpu_arch_isa_flags. (md_parse_option): Likewise. (optimize_encoding): Check i.tm.cpu_flags and cpu_arch_isa_flags for cpuavx512vl instead of cpu_arch_flags. Optimize EVEX with EVEX128 when EVEX encoding is required. * testsuite/gas/i386/i386.exp: Run optimize-4, optimize-5, x86-64-optimize-5 and x86-64-optimize-6. * testsuite/gas/i386/optimize-1.d: Updated. * testsuite/gas/i386/x86-64-optimize-2.d: Likewise. * testsuite/gas/i386/optimize-4.d: New file. * testsuite/gas/i386/optimize-4.s: Likewise. * testsuite/gas/i386/optimize-5.d: Likewise. * testsuite/gas/i386/optimize-5.s: Likewise. * testsuite/gas/i386/x86-64-optimize-5.d: Likewise. * testsuite/gas/i386/x86-64-optimize-5.s: Likewise. * testsuite/gas/i386/x86-64-optimize-6.d: Likewise. * testsuite/gas/i386/x86-64-optimize-6.s: Likewise.
2018-03-08Fix misreporting of omitted bytes for large remote packetsSimon Marchi2-10/+11
In remote.c, when the output of "set debug remote" is truncated, the number of characters reported is incorrect. What is reported is the number of characters added by the quoting, not the number of characters that were truncated. gdb/ChangeLog: * remote.c (putpkt_binary): Fix omitted bytes reporting. (getpkt_or_notif_sane_1): Likewise.
