2018-09-13x86: also allow D on 3-operand insnsJan Beulich5-115/+47
For now this is just for VMOVS{D,S}.
2018-09-13x86: use D attribute also for SIMD templatesJan Beulich10-1286/+291
Various moves come in load and store forms, and just like on the GPR and FPU sides there would better be only one pattern. In some cases this is not feasible because the opcodes are too different, but quite a few cases follow a similar standard scheme. Introduce Opcode_SIMD_FloatD and Opcode_SIMD_IntD, generalize handling in operand_size_match() (reverse operand handling there simply needs to match "straight" operand one), and fix a long standing, but so far only latent bug with when to zap found_reverse_match. Also once again drop IgnoreSize where pointlessly applied to templates touched anyway as well as *word when redundant with Reg*.
2018-09-13x86: fold ILP32 output of "opts" testsJan Beulich5-1296/+12
The output is identical to that of the LP64 tests. No need to fully spell this out twice.
2018-09-13x86: improve operand reversalJan Beulich6-11/+970
In quite a few cases the .s suffix or {load} / {store} prefixes did not work as intended, or produced errors when they're supposed to be ignored when it is not possible to carry out the request. The change here re-purposes(?) the .s suffix to no longer mean "store" (if that's what 's' did stand for), since the forms used in the base templates are not consistently loads (and we unlikely want to change that). The pseudo prefixes will now fulfill what their names say, i.e. {load} now only ever produces a load form encoding (if available) while {store} only ever produces a store form one (again if available). This requires minimal test suite adjustments, while the majority of the changes there are simply additions.

2018-09-12Move 'is_regular_file' from common-utils.c to filestuff.cSergio Durigan Junior5-37/+44
There is no reason for 'is_regular_file' to be in common-utils.c; it belongs to 'filestuff.c'. This commit moves the function definition and its prototype to the appropriate files. The motivation behind this move is a failure that happens on certain cross-compilation environments when compiling the IPA library, due to the way gnulib probes the need for a 'stat' call replacement. Because configure checks when cross-compiling are more limited, gnulib decides that it needs to substitute the 'stat' calls its own 'rpl_stat'; however, the IPA library doesn't link with gnulib, which leads to an error when compiling 'common-utils.c': ... /opt/x86-core2--musl--bleeding-edge-2018.09-1/bin/i686-buildroot-linux-musl-g++ -shared -fPIC -Wl,--soname=libinproctrace.so -Wl,--no-undefined -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Os -I. -I. -I./../common -I./../regformats -I./.. -I./../../include -I./../gnulib/import -Ibuild-gnulib-gdbserver/import -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Wall -Wpointer-arith -Wno-unused -Wunused-value -Wunused-function -Wno-switch -Wno-char-subscripts -Wempty-body -Wunused-but-set-parameter -Wunused-but-set-variable -Wno-sign-compare -Wno-narrowing -Wno-error=maybe-uninitialized -DGDBSERVER \ -Wl,--dynamic-list=./proc-service.list -o libinproctrace.so ax-ipa.o common-utils-ipa.o errors-ipa.o format-ipa.o print-utils-ipa.o regcache-ipa.o remote-utils-ipa.o rsp-low-ipa.o tdesc-ipa.o tracepoint-ipa.o utils-ipa.o vec-ipa.o linux-i386-ipa.o linux-x86-tdesc-ipa.o arch/i386-ipa.o -ldl -pthread /opt/x86-core2--musl--bleeding-edge-2018.09-1/lib/gcc/i686-buildroot-linux-musl/8.2.0/../../../../i686-buildroot-linux-musl/bin/ld: common-utils-ipa.o: in function `is_regular_file(char const*, int*)': common-utils.c:(.text+0x695): undefined reference to `rpl_stat' collect2: error: ld returned 1 exit status Makefile:413: recipe for target 'libinproctrace.so' failed make[1]: *** [libinproctrace.so] Error 1 ... More details can also be found at: https://sourceware.org/ml/gdb-patches/2018-09/msg00304.html The most simple fix for this problem is to move 'is_regular_file' to 'filestuff.c', which is not used by IPA.

2018-09-12Add debug output about skipping files and functionsSimon Marchi5-25/+103
While trying to create skips for libstdc++, I found myself debugging GDB quite a bit, mostly to find out what the exact function name to match is.

2018-09-11Darwin: fix SIGTRAP when debuggingXavier Roirand2-6/+14
Debugging a program under Darwin does not work: (gdb) start Temporary breakpoint 1 at 0x100000fb4: file /tmp/helloworld.c, line 1. Starting program: /private/tmp/helloworld [New Thread 0x2903 of process 60326] During startup program terminated with signal SIGTRAP, Trace/breakpoint trap. Field signaled from darwin_thread_info is not initialized thus signal sent to the debuggee is considered as not sent by GDB whereas it should.

2018-09-10Fix PR gdb/23558: Use system's 'getcwd' when cross-compiling GDBSergio Durigan Junior2-4/+23
This is a backport of a gnulib fix for the following bug: https://sourceware.org/bugzilla/show_bug.cgi?id=23558 The problem reported there is about the replacement of 'getcwd' when cross-compiling GDB. With our current gnulib copy, the mechanism for deciding whether to use the system's 'getcwd' or gnulib's version is too simplistic and pessimistic, so when cross-compiling we always end up using gnulib's version, which has a limitation: it cannot handle the situation when the parent directory doesn't have read permissions. The solution is to backport the following gnulib commit: commit a96d2e67052c879b1bcc5bc461722beac75fc372 Author: Bruno Haible <bruno@clisp.org> Date: Thu Aug 23 21:13:19 2018 +0200 getcwd: Add cross-compilation guesses. gdb/ChangeLog: 2018-09-10 Sergio Durigan Junior <sergiodj@redhat.com> PR gdb/23555 PR gdb/23558 * gnulib/import/m4/getcwd-path-max.m4: Add cross-compilation guesses.
2018-09-10Revert "Update gnulib to current upstream master"Sergio Durigan Junior317-12141/+8356
This reverts commit 7a6dbc2fdb2323c35e981f93236f323e9d7c0b24 ("Update gnulib to current upstream master"). It is needed because the gnulib update caused problems with people using old GCC compilers (version 4.8, for example), which support C99 but don't default to using it. Unfortunately this broke GDB for these users. A more detailed report of what happened can be found at: https://lists.gnu.org/archive/html/bug-gnulib/2018-08/msg00157.html The reason for updating our gnulib copy was to fix PR gdb/23558. Reverting this patch reintroduces the bug, so in order to fix it I will submit a subsequent patch which cherry-picks the fix from gnulib. gdb/ChangeLog: 2018-09-10 Sergio Durigan Junior

2018-09-10(Ada) Fix resolving of homonym components in tagged typesJerome Guitton7-7/+81
ada_value_struct_elt is used when displaying a component (say, 'N') of a record object (say, 'Obj') of type, say, 't1'. Now if Obj is tagged (Ada parlance: "tagged types" are what other object-oriented languages call "classes"), then 'N' may not be visible in the current view and we need to look for it in its actual type. We do that at the same time as resolving variable-length fields. This would typically be done by the following call to ada_value_struct_elt, with the last parameter check_tag set to 1: t1 = ada_to_fixed_type (ada_get_base_type (t1), NULL, address, NULL, 1); This is the general logic, but recently we introduced a special case to handle homonyms. Different components may have the same name in a tagged type. For instance: type Top_T is tagged record N : Integer := 1; end record; type Middle_T is new Top.Top_T with record N : Character := 'a'; end record; Middle_T extends Top_T and both define a (different) component with the same name ('N'). In such a case, using the actual type of a Middle_T object would create a confusion, since we would have two component 'N' in this actual type. So, to handle homonyms, we convert t1 to the actual type *if and only if* N cannot be found in the current view. For example, if Obj has been created as a Middle_T but is seen as a Top_T'Class at our point of execution, then "print Obj.N" will display the integer field defined in Top_T's declaration. Now, even if we find N in the current view, we still have to get a fixed type: for instance, the record can be unconstrained and we still need a fixed type to get the proper offset to each field. That is to say, in this case: type Dyn_Top_T (Disc : Natural) is tagged record S : Integer_Array (1 .. Disc) := (others => Disc); N : Integer := 1; end record; type Dyn_Middle_T is new Dyn_Top.Dyn_Top_T with record N : Character := 'a'; U : Integer := 42; end record; If we have an object Obj of type Dyn_Middle_T and we want to display U, we don't need to build, from its tag, a real type with all its real fields. In other words, we don't need to add the parent components: Disc, S, and the integer N. We only need to access U and it is directly visible in Dyn_Middle_T. So no tag handling. However, we do need to build a fixed-size type to have the proper offset to U (since this offset to U depends on the size of Obj.S, which itself is dynamic and depends on the value of Obj.Disc). We accidentally lost some of this treatment when we introduced the resolution of homonyms. This patch re-install this part by uncoupling the tag resolution from the "fixing" of variable-length components. This change also slightly simplifies the non-tagged case: in the non-tagged case, no need to set check_tag to 1, since we already know that there is no tag. gdb/ChangeLog: * ada-lang.c (ada_value_struct_elt): Call ada_to_fixed_type with check_tag to 1 if and only if the type is tagged and the component being searched cannot been found in the current view. Otherwise, always call ada_to_fixed_type with check_tag to 0. gdb/testsuite/ChangeLog: * gdb.ada/same_component_name: Add test for case of tagged record with variable-length fields.

2018-09-10(Ada) Fix printing of access to unconstrained arraysXavier Roirand7-1/+109
Using this Ada code: type String_Access is access String; type Array_Of_String is array (1 .. 2) of String_Access; Aos : Array_Of_String := (new String'("ab"), new String'("cd")); When debugging with GDB, printing each Aos element displays: (gdb) print Aos(1) $2 = "ab" (gdb) print Aos(2) $3 = "cd" Whereas it should display: (gdb) print Aos(1) $2 = (foo_r118_024.string_access) 0x635018 (gdb) print Aos(2) $3 = (foo_r118_024.string_access) 0x635038 Notice that printing the entire array works: (gdb) print Aos $1 = (0x635018, 0x635038) The problem was located in ada_value_print function and due to the fact that the value_type used in this function was based on value_enclosing_type rather than value_type itself. In our example, the difference between the value_type and the value_enclosing_type of the value is that the value_type contains an additional typedef layer which is not present in the value_enclosing_type. This typedef layer is GNAT's way to specify that the element is, at the source level, an access to the unconstrained array, rather than the unconstrained array. Moreover, the value_enclosing_type is not really needed in that case and the value_type can be used instead in this function, and this patch fixes this. gdb/ChangeLog: * ada-valprint.c (ada_value_print): Use type instead of enclosing type. testsuite/ChangeLog: * gdb.ada/access_to_unbounded_array.exp: New testcase. * gdb.ada/access_to_unbounded_array/foo.adb: New file. * gdb.ada/access_to_unbounded_array/pack.adb: New file. * gdb.ada/access_to_unbounded_array/pack.ads: New file.
