* Eliminate mi_run_to_main, introduce mi_clean_restartusers/palves/runto_mainPedro Alves2020-10-1259-400/+184
| | | | | | | | | | | | | | | | Since we now have mi_runto_main which is like runto_main, eliminate mi_run_to_main, in favor of a new MI clean_restart counterpart -- mi_clean_restart -- and mi_runto_main. This makes MI testcases look a bit more like CLI testcases. gdb/testsuite/ChangeLog: * lib/mi-support.exp (mi_clean_restart): New. (mi_run_to_main): Delete. All callers adjust to use mi_clean_restart / mi_runto_main. Change-Id: I34920bab4fea1f23fb752928c2969c1f6ad714b6

* gdb/testsuite/: Use -qualified in runto_main / mi_runto_mainPedro Alves2020-10-124-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some runtimes, there may be a "main" function in some class or namespace. The breakpoint created by runto_main may therefore have unexpected locations on some other functions than the actual main. These breakpoint locations can unexpectedly get hit during tests and lead to failures. I saw this while playing with AMD's ROCm toolchain -- I wrote a board file to run the testsuite against device kernels. There, the runtime calls a "main" function before the device kernel code is reached: Thread 4 "bit_extract" hit Breakpoint 1, 0x00007ffeea140960 in lld::elf::LinkerDriver::main(llvm::ArrayRef<char const*>) () from /opt/rocm/lib/libamd_comgr.so.1 (gdb) bt #0 0x00007ffeea140960 in lld::elf::LinkerDriver::main(llvm::ArrayRef<char const*>) () from /opt/rocm/lib/libamd_comgr.so.1 #1 0x00007ffeea2257a5 in lld::elf::link(llvm::ArrayRef<char const*>, bool, llvm::raw_ostream&, llvm::raw_ostream&) () from /opt/rocm/lib/libamd_comgr.so.1 #2 0x00007ffeea1bc374 in COMGR::linkWithLLD(llvm::ArrayRef<char const*>, llvm::raw_ostream&, llvm::raw_ostream&) () from /opt/rocm/lib/libamd_comgr.so.1 #3 0x00007ffeea1bfb09 in COMGR::InProcessDriver::execute(llvm::ArrayRef<char const*>) () from /opt/rocm/lib/libamd_comgr.so.1 #4 0x00007ffeea1c4da9 in COMGR::AMDGPUCompiler::linkToExecutable() () from /opt/rocm/lib/libamd_comgr.so.1 #5 0x00007ffeea1fde20 in dispatchCompilerAction(amd_comgr_action_kind_s, COMGR::DataAction*, COMGR::DataSet*, COMGR::DataSet*, llvm::raw_ostream&) () from /opt/rocm/lib/libamd_comgr.so.1 #6 0x00007ffeea203a87 in amd_comgr_do_action () from /opt/rocm/lib/libamd_comgr.so.1 ... To avoid that, pass "qualified" to runto, in runto_main, so that gdb_breakpoint ends up creating a breakpoint with -qualified. This avoids creating breakpoints locations for other unrelated "main" functions. Note: I first tried making runto itself use "-qualified", but that caused regressions in the gdb.ada/ tests, which use runto without specifying the whole fully-qualified function name (i.e., without the package). So I end up restricting the -qualified to runto_main/mi_runto_main. The gdb.base/ui-redirect.exp change is necessary because that testcase is looking at what "save breakpoint" generates. gdb/testsuite/ChangeLog: * gdb.base/ui-redirect.exp: Expect "break -qualified main" in saved breakpoints file. * gdb.guile/scm-breakpoint.exp: Expect "-qualified main" when inspecting breakpoint list. * lib/gdb.exp (runto_main): Add "qualified" to options. * lib/mi-support.exp (mi_runto_helper): Add 'qualified' parameter, and handle it. (mi_runto_main): Pass 1 as qualified argument. Change-Id: I51468359ab0a518f05f7c0394c97f7e33b45fe69
* Introduce mi_runto_mainPedro Alves2020-10-1211-18/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds an mi_runto_main routine, very much like the runto_main CLI counterpart. Note there's already a mi_run_to_main (extra underscore in "run_to"), but unlike its intro comment says, that does more than the CLI's runto_main -- it also starts GDB. I would like to eliminate that other one by introducing a mi_clean_restart function instead. That is done later in the series. gdb/testsuite/ChangeLog: * lib/mi-support.exp (mi_runto_main): New proc.

* gdb: detect main function even when there's no matching msymbolAndrew Burgess2020-10-114-10/+33
| | | | | | | | | | | | | | | | | | | | | | | Currently, GDB will only stop the backtrace at the main function if there is a minimal symbol with the matching name. In Fortran programs compiled with gfortran this is not the case. The main function is present in the DWARF, and as marked as DW_AT_main_subprogram, but there's no minimal symbol. This commit extends `inside_main_func` to check the full symbols if no matching minimal symbol is found. There's an updated test case that covers this change. gdb/ChangeLog: * frame.c (inside_main_func): Check full symbols as well as minimal symbols. gdb/testsuite/ChangeLog: * gdb.fortran/mixed-lang-stack.exp (run_tests): Update expected output of backtrace.

* Handle void results as unformatted printsHannes Domani2020-10-094-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When printing void results without any format letter, they are output as expected: (gdb) p $abcd $1 = void (gdb) p (void)10 $2 = void But if any format letter (besides s) is used, it always outputs zero: (gdb) p/x $abcd $3 = 0x0 (gdb) p/x (void)10 $4 = 0x0 So this adds void results to the types handled like unformatted prints. gdb/ChangeLog: 2020-10-09 Hannes Domani <ssbssa@yahoo.de> PR exp/26714 * printcmd.c (print_formatted): Handle void results as unformatted prints. gdb/testsuite/ChangeLog: 2020-10-09 Hannes Domani <ssbssa@yahoo.de> PR exp/26714 * gdb.base/printcmds.exp: Add tests for void results.

* gnulib: Ensure all libraries are used when building gdb/gdbserverAndrew Burgess2020-10-099-10/+77

In fact I think the issue is bigger than just LIB_GETRANDOM. When using the script binutils-gdb/gnulib/update-gnulib.sh to reimport gnulib there is a lot of output from gnulib's gnulib-tool. Part of that output is this: You may need to use the following makefile variables when linking. Use them in <program>_LDADD when linking a program, or in <library>_a_LDFLAGS or <library>_la_LDFLAGS when linking a library. $(FREXPL_LIBM) $(FREXP_LIBM) $(INET_NTOP_LIB) $(LIBTHREAD) $(LIB_GETLOGIN) $(LIB_GETRANDOM) $(LIB_HARD_LOCALE) $(LIB_MBRTOWC) $(LIB_SETLOCALE_NULL) $(LTLIBINTL) when linking with libtool, $(LIBINTL) otherwise What I think this is telling us is that we should be including the value of all these variables on the link line for gdb and gdbserver. The problem though is that these variables are define in gnulib's makefile, but are not (necessarily) defined in GDB's makefile. One solution would be to recreate the checks that gnulib performs in order to recreate these variables in both gdb's and gdbserver's makefile. Though this shouldn't be too hard, most (if not all) of these checks are in the form macros defined in m4 files in the gnulib tree, so we could just reference these as needed. However, in this commit I propose a different solution. Currently, in the top level makefile, we give gdb and gdbserver a dependency on gnulib. Once gnulib has finished building gdb and gdbserver can start, these projects then have a hard coded (relative) path to the compiled gnulib library in their makefiles. In this commit I extend the gnulib configure script to install a new makefile fragment in the gnulib build directory. This new file will have the usual variable substitutions applied to it, and so can include the complete list (see above) of all the extra libraries that are needed when linking against gnulib. In fact the new makefile fragment defines three variables, these are: LIBGNU: The path to the archive containing gnulib. Can be used as a dependency as when this file changes gdb/gdbserver should be relinked. LIBGNU_EXTRA_LIBS: A list of linker -l.... flags that should be included in the link line of gdb/gdbserver. These are libraries that $(LIBGNU) depends on. This list is taken from the output of gnulib-tool, which is run by our gnulib/update-gnulib.sh script. INCGNU: A list of -I.... include paths that should be passed to the compiler, these are where the gnulib headers can be found. Now both gdb and gdbserver can include the makefile fragment and make use of these variables. The makefile fragment relies on the variable GNULIB_BUILDDIR being defined. This is checked for in the fragment, and was already defined in the makefiles of gdb and gdbserver. gdb/ChangeLog: * Makefile.in: Include Makefile.gnulib.inc. Don't define LIBGNU or INCGNU.

* [GOLD] Increase --split-stack-adjust-sizeAlan Modra2020-10-082-1/+5
| | | | | | | | | | | For functions with small (< 256 bytes) stack frames, the current x86 do_calls_non_split ignores --split-stack-adjust-size and, in combination with __morestack_non_split, supplies a non-split-stack function with at least 0x100000 (1M) available stack. On powerpc64, a default of 0x4000 is not large enough to reliably work with the golang testsuite. This increase the default size to the defacto x86 value. * options.h (split_stack_adjust_size): Default to 0x100000.

* gdb: put user-supplied CFLAGS at the endSimon Marchi2020-10-074-6/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GDB currently doesn't build cleanly with clang (a -Wdeprecated-copy-dtor error). I configured my clang-based GDB build with CXXFLAGS="-Wno-error=deprecated-copy-dtor", so I can use it despite that problem. However, I found that it had no effect. This is because my -Wno-error=Wdeprecated-copy-dtor switch is followed by -Werror in the command line, which switches back all warnings to be errors. If we want the user-supplied C(XX)FLAGS to be able to override flags added by our configure script, the user-supplied C(XX)FLAGS should appear after the configure-supplied flags. This patch moves the user-supplied CXXFLAGS at the very end of the compilation command line, which fixes the problem described above. This means moving it out of INTERNAL_CFLAGS and inlining it in the users of INTERNAL_CFLAGS. I observed the problem when building GDB, but the same problem could happen with GDBserver, so the change is done there too. In GDBserver, INTERNAL_CFLAGS is passed when linking gdb/ChangeLog: * Makefile.in (COMPILE): Add CXXFLAGS. (INTERNAL_CFLAGS_BASE): Remove CXXFLAGS.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the implemenations in this patch, ARC gdb can handle coredump related matters. The binutils counter part of this patch has already been pushed [1]. v2 [2]: - arc_linux_collect_gregset: Use "reg <= ARC_LAST_REGNUM" instead of "reg < ARC_LAST_REGNUM" for the condition check of the for-loop. - arc-linux-tdep.c: Use "ARC_LAST_REGNUM < ARRAY_SIZE (...)" instead of "ARC_LAST_REGNUM <= ARRAY_SIZE (...)" for the "asserts". - Use "buf + arc_linux_core_reg_offsets[ARC_ERET_REGNUM]" instead of "buf + REG_OFF (6)". - Fix a few typos/indentation. v3 [3]: - Use gdb_assert_not_reached(text) instead of gdb_assert (!text). - Remove unnecessary braces in the for loop.

* gdbserver: Add GNU/Linux support for ARCAnton Kolesov2020-10-074-0/+437
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This gdbserver implementation supports ARC ABI v3 and v4 (older ARC ABI versions are not supported by other modern GNU tools or Linux itself). Gdbserver supports inspection of ARC HS registers R30, R58 and R59 - feature that has been added to Linux 4.12. Whether gdbserver build will actually support this feature depends on the version of Linux headers used to build the server. v2 [1]: - Use "this->read_memory ()" instead of "the_target->read_memory ()". - Remove the unnecessary "arch-arc.o:" target from the "Makefile.in". - Got rid of "ntohs()" function and added lots of comments about endianness. - Clarify why "pc" value is read from and saved to different fields in user regs struct. - In function "is_reg_name_available_p()", use a range-based iterator to loop over the registers. - Removed mentioning of issue number that was not related to sourceware. - A few typo's fixed.

* arc: Rename "arc_gdbarch_features" structShahab Vahedi2020-10-074-19/+26
| | | | | | | | | | | | | | | | "arc_gdbarch_features" is a data structure containing information about the ARC architecture: ISA version, register size, etc. This name is misleading, because although it carries the phrase "gdbarch", it has nothing to do with the type/interface in GDB. Traditionaly, "gdbarch" structures are only used for that purpose. To rectify this, this patch changes the name to "arc_arch_features". gdb/ChangeLog: * arch/arc.h: Rename "arc_gdbarch_features" to "arc_arch_features". * arc-tdep.h: Likewise. * arc-tdep.c: Likewise.
