Ulrich Weigand	0e5fae36f1	S/390: Rename source files to -linux- As suggested before, rename the S/390-related source files (tdep and nat) such that "-linux-" occurs in the file name, like with other GNU/Linux targets. Since no other operating system is currently supported by GDB on this architecture, this isn't strictly necessary. But the old names sometimes caused GDB contributors to miss these files when performing a change that affects all GNU/Linux targets. The latest such incident was observed here: https://sourceware.org/ml/gdb-patches/2013-09/msg00619.html gdb/ 2013-10-30 Andreas Arnez <arnez@linux.vnet.ibm.com> * s390-tdep.h: Rename to... * s390-linux-tdep.h: ...here. * s390-tdep.c: Rename to... * s390-linux-tdep.c: ...here.

Andreas Arnez	7d4a7d107a	S/390: Disassemble 31-bit binaries with "zarch" opcode set by default Currently the disassembler for s390 (by default) assumes that a 31-bit binary was compiled in "ESA" mode -- and then only disassembles a limited opcode set. The change upgrades the default to the full "zarch" opcode set even for 31-bit binaries. opcodes/ * s390-dis.c (init_disasm): Default to full 'zarch' opcode availability even for 31-bit programs.	13 years ago

Alan Modra	b9e5796b0d	ELFv2 stub, plt and glink changes An ELFv2 PLT entry is simply the address of the target function rather than three (or two) words to specify entry, toc and static chain. PLT call stubs are correspondingly simpler and need no thread safety barrier. The glink resolver stub and branch table also is simplified, a change that could be applied to ELFv1 too, but isn't as yet. * elf64-ppc.c (PLT_ENTRY_SIZE, PLT_INITIAL_ENTRY_SIZE): Add htab parameter and adjust for ELFv2.

Alan Modra	f9c6b9078c	Report overflow on PowerPC64 @h and @ha relocations. This changes the behaviour of @h and @ha on PowerPC64 to report errors on 32-bit overflow. The motivation for this change is that on PowerPC64, most uses of @h and @ha modifiers and their corresponding relocations are to build up 32-bit offsets. We'd like to know when such offsets overflow. Only rarely do people use @h or @ha with the high 32-bit modifiers to build a 64-bit constant. Those uses will now need to use two new modifiers, @high and @higha, if the constant isn't known at assembly time. For now, we won't report overflow at assembly time.. This also fixes an error when applying some of the HIGHER and HIGHEST relocations. include/elf/ * ppc64.h (R_PPC64_ADDR16_HIGH, R_PPC64_ADDR16_HIGHA, R_PPC64_TPREL16_HIGH, R_PPC64_TPREL16_HIGHA, R_PPC64_DTPREL16_HIGH, R_PPC64_DTPREL16_HIGHA): New.

Jan Beulich	34a79995c4	ld/ELF: refine fake STT_FILE symbol emission There's no real need to emit these always: They're needed only if we indeed want to emit a localized symbol. Hence defer emission until we at least did the basic early checks that would lead to no such symbol getting emitted. This in particular avoids emitting such a symbol in the majority of (if not all) "ld -r" cases.

Tom Tromey	aee17e424f	undef reg in gdb_curses.h I tried to build gdb on the AIX machine in the GCC compile farm (gcc111), but it failed in a couple of spots because gdb uses "reg" as a variable name and the AIX <curses.h> defines "reg" to "register". I saw that we already had a workaround for this lurking in utils.c, so I just moved that to gdb_curses.h.

Pedro Alves	fcf3daefe6	infrun.c:handle_inferior_event: Move process_event_stop_test goto label. We only ever call "goto process_event_stop_test;" right after checking that ecs->random_signal is clear. The code at the process_event_stop_test label looks like: /* For the program's own signals, act according to the signal handling tables. / if (ecs->random_signal) { ... random signal handling ... return; } else { ... the stop tests that actually matter for the goto callers. } So this moves the label into the else branch. It'll make converting process_event_stop_test into a function a bit clearer. gdb/ 2013-10-28 Pedro Alves <palves@redhat.com> infrun.c (handle_inferior_event): Move process_event_stop_test goto label to the else branch of the ecs->random_signal check, along with FRAME and GDBARCH re-fetching.	13 years ago
Pedro Alves	c447ac0bfb	infrun.c:handle_inferior_event: Put all ecs->random_signal tests together. I recently added a new ecs->random_signal test after the "switch back to stepped thread" code, and before the stepping tests. Looking at making process_event_stop_test a proper function, I realized it'd be better to keep ecs->random_signal related code together. To do that, I needed to factor out the "switch back to stepped thread" code to a new function, and call it in both the "random signal" and "not random signal" paths. gdb/ 2013-10-28 Pedro Alves <palves@redhat.com> * infrun.c (switch_back_to_stepped_thread): New function, factored out from handle_inferior_event. (handle_inferior_event): Adjust to call switch_back_to_stepped_thread. Call it also at the tail of the random signal handling, and return, instead of also handling random signals just before the stepping tests.	13 years ago
Pedro Alves	f05e4c1115	infrun.c:handle_inferior_event: Remove some more dead code. 'ecs' is always memset before being passed to handle_inferior_event. The stop func is only filled in later in the flow. And since "Remove dead sets/clears of ecs->random signal", nothing ever sets ecs->random_signal before this part is reached either. (Also tested with some added assertions in place.) gdb/ 2013-10-28 Pedro Alves <palves@redhat.com> * infrun.c (clear_stop_func): Delete. (handle_inferior_event): Don't call clear_stop_func and don't clear 'ecs->random_signal'.	13 years ago

Yao Qi	a53b64eaa0	New field la_varobj_ops in struct language_defn This is a follow-up series to move language stuff out of varobj.c. This patch adds a new field la_varobj_ops in struct language_defn so that each language has varobj-related options. Not every language supports varobj, and the operations are identical to operations of c languages. 'struct language_defn' is the ideal place to save all language-related operations. After this patch, some cleanups can be done in patch 2/2, which removes language-related stuff completely from varobj.c. Regression tested on x86_64-linux. gdb: 2013-10-25 Yao Qi <yao@codesourcery.com> * language.h (struct lang_varobj_ops): Declare.

Anton Kolesov	38095c27fb	testsuite: Fix gdb.base/bang.exp for remote stubs without exit Some remote stubs do not have a proper exit() function implementation. gdb.base/bang.exp was failing on those targets due to timeout. With this patch bang.exp uses already defined library procedures to handle this situation gracefully without breaking native targets. Tested with x86_64 (unix, native-gdbserver) and with arc--elf32. gdb/testsuite/ChangeLog: 2013-10-25 Anton Kolesov <Anton.Kolesov@synopsys.com> (tiny change) gdb.base/bang.exp: Use gdb_continue_to_end to properly support remote stubs where exit() behaviour is unreliable.	13 years ago
Pedro Alves	686d4defdf	Print nonexisting/optimized out static fields gracefully. With: struct static_struct { static int aaa; }; struct static_struct sss; int main () { return 0; } We get: (gdb) p sss $1 = {static aaa = <optimized out>} (gdb) p sss.aaa field aaa is nonexistent or has been optimized out Note that the "field aaa ..." message is an error being thrown. GDB is graceful everywhere else when printing optimized out values. IOW it usually prints an <optimized out> value and puts that in the value history. I see no reason for here to be different, more so that when the print the whole "containing" object (well, it's a static field, so it's not really a container), we already print <optimized out>. After the patch: (gdb) p sss $1 = {static aaa = <optimized out>} (gdb) p sss.aaa $2 = <optimized out> The value_entirely_optimized_out checks are there to preserve behavior. Without those, if the static field is a struct/union, GDB would go and print its fields one by one (and print <optimized out> for each). Tested on x86_64 Fedora 17. gdb/ 2013-10-25 Pedro Alves <palves@redhat.com> * cp-valprint.c (cp_print_value_fields): No longer handle a NULL static field value. (cp_print_static_field): If the value is entirely optimized out, print <optimized out> here. * jv-valprint.c (java_print_value_fields): No longer handle a NULL static field value. * p-valprint.c (pascal_object_print_static_field): If the value is entirely optimized out, print <optimized out> here. * valops.c (do_search_struct_field) (value_struct_elt_for_reference): No longer handle a NULL static field value. * value.c (value_static_field): Return an optimized out value instead of NULL. gdb/testsuite/ 2013-10-25 Pedro Alves <palves@redhat.com> * gdb.cp/m-static.exp: Adjust expected output of printing a nonexistent or optimized out static field. Also test printing the the "container" object.	13 years ago
