2019-05-09[binutils][aarch64] SVE2 feature extension flags.Matthew Malcomson7-0/+90
Include all feature flag macros. The "sve2" extension that enables the core sve2 instructions. This also enables the sve extension, since sve is a requirement of sve2. Extra optional sve2 features are the bitperm, sm4, aes, and sha3 extensions. These are all given extra feature flags, "bitperm", "sve2-sm4", "sve2-aes", and "sve2-sha3" respectively. The sm4, aes, and sha3 extensions are explicitly marked as sve2 extensions to distinguish them from the corresponding NEON extensions. Rather than continue extending the current feature flag numbers, I used some bits that have been skipped. gas/ChangeLog: 2019-05-09 Matthew Malcomson <matthew.malcomson@arm.com> * config/tc-aarch64.c: Add command line architecture feature flags "sve2", "sve2-sm4", "sve2-aes", "sve2-sha3", "bitperm". * doc/c-aarch64.texi: Document new architecture feature flags. include/ChangeLog: 2019-05-09 Matthew Malcomson <matthew.malcomson@arm.com> * opcode/aarch64.h (AARCH64_FEATURE_SVE2 AARCH64_FEATURE_SVE2_AES, AARCH64_FEATURE_SVE2_BITPERM, AARCH64_FEATURE_SVE2_SM4, AARCH64_FEATURE_SVE2_SHA3): New feature macros. opcodes/ChangeLog: 2019-05-09 Matthew Malcomson <matthew.malcomson@arm.com> * aarch64-tbl.h (aarch64_feature_sve2, aarch64_feature_sve2aes, aarch64_feature_sve2sha3, aarch64_feature_sve2sm4, aarch64_feature_sve2bitperm): New feature sets.

2019-05-09[gdb/testsuite] Fix gdb.arch/amd64-entry-value-paramref.STom de Vries2-13/+18
The file gdb.arch/amd64-entry-value-paramref.S contains a DIE for function bar: ... DIE29: .uleb128 0x2 # (DIE (0x29) DW_TAG_subprogram) .ascii "bar\0" # DW_AT_name .byte 0x1 # DW_AT_decl_file (gdb.arch/amd64-entry-value-paramref.cc) .byte 0x15 # DW_AT_decl_line .long DIE45 # DW_AT_type .byte 0x1 # DW_AT_inline ... which refers to DIE45: ... DIE45: .uleb128 0x4 # (DIE (0x45) DW_TAG_base_type) .byte 0x4 # DW_AT_byte_size .byte 0x5 # DW_AT_encoding .ascii "int\0" # DW_AT_name ... using a form DW_FORM_ref4: ... .uleb128 0x2 # (abbrev code) .uleb128 0x2e # (TAG: DW_TAG_subprogram) .byte 0x1 # DW_children_yes ... .uleb128 0x49 # (DW_AT_type) .uleb128 0x13 # (DW_FORM_ref4) ... However, the DW_FORM_ref4 is a CU-relative reference, while using a label for the value will result in a section-relative value. So, if linked in object files contain dwarf info and are placed in the .debug_info section before the compilation units generated from amd64-entry-value-paramref.S, then the referenced type is at 0x108: ... <1><108>: Abbrev Number: 4 (DW_TAG_base_type) <109> DW_AT_byte_size : 4 <10a> DW_AT_encoding : 5 (signed) <10b> DW_AT_name : int ... but the reference will point to a non-existing DIE at 0x1cf: ... <1><f0>: Abbrev Number: 2 (DW_TAG_subprogram) <f1> DW_AT_name : bar <f5> DW_AT_decl_file : 1 <f6> DW_AT_decl_line : 21 <f7> DW_AT_type : <0x1cf> <fb> DW_AT_inline : 1 (inlined) ... which happens to cause a GDB internal error described in PR23270 - "GDB internal error: dwarf2read.c:18656: internal-error: could not find partial DIE 0x1b7 in cache". Fix the invalid DWARF by making the reference value CU-relative: ... - .long DIE45 # DW_AT_type + .long DIE45 - .Ldebug_info0 # DW_AT_type ... Tested on x86_64-linux. gdb/testsuite/ChangeLog: 2019-05-09 Tom de Vries <tdevries@suse.de> * gdb.arch/amd64-entry-value-paramref.S: Make DW_FORM_ref4 references CU-relative.

Now display the backtrace: (gdb) bt #0 break_me () at [...] #1 0x000000000040243e in pck.call_me ( s={P_ARRAY = 0x7fffffffe21c, P_BOUNDS = 0x41e6e8}) at [...] whereas we should expect: (gdb) bt #0 break_me () at [...] #1 0x000000000040243e in pck.call_me (s="test") at [...] The problem is that GDB prints the S parameter in the pck.call_me Ada function using the current language, so the C one, because the program is stopped in a C function, whereas it should use the pck.call_me frame one. This behavior is ok when user manually changes the language but it's not the right one when language is auto. This patch fixes this problem so now when using auto language, all Ada frame arguments are printed using Ada like syntax when the frame is part of Ada code, even if the program is stopped in a frame using a different language. If the user explicitly sets a language (using "set language ...") then no change here, all the Ada frame arguments are printed using this language. gdb/ChangeLog: * ada-valprint.c (ada_val_print_gnat_array): Remove language parameter and use Ada language definition instead.

2019-05-08Change some remote.c globals to "static"Tom Tromey2-3/+9
I noticed a three globals in remote.c that could be static. This patch makes this change. gdb/ChangeLog 2019-05-08 Tom Tromey <tromey@adacore.com> * remote.c (remote_hw_watchpoint_limit) (remote_hw_watchpoint_length_limit, remote_hw_breakpoint_limit): Now static.
2019-05-08Move "watchdog" to remote.cTom Tromey4-28/+34
The "watchdog" global is only used in remote.c, so this patch moves it there and makes it static. gdb/ChangeLog 2019-05-08 Tom Tromey <tromey@adacore.com> * maint.c (_initialize_maint_cmds): Move initialization code to remote.c. (watchdog, show_watchdog): Move to remote.c. * remote.c (watchdog, show_watchdog): Move from maint.c. Make "watchdog" static. (_initialize_remote): Move initialization code from maint.c. * defs.h (watchdog): Don't declare.
2019-05-08Move interpreter_p declaration to main.hTom Tromey5-3/+12
This moves the interpreter_p declaration from defs.h to main.h. I think this makes more sense, as it is defined in main.c. Also, this declaration was in the wrong place -- between a comment and the things the comment described. gdb/ChangeLog 2019-05-08 Tom Tromey <tromey@adacore.com> * tui/tui-interp.c: Include main.h. * interps.c: Include main.h. * main.h (interpreter_p): Declare. * defs.h (interpreter_p): Don't declare.
2019-05-08Don't declare read_unsigned_leb128 in defs.hTom Tromey4-4/+9
I noticed that read_unsigned_leb128 is declared in defs.h. There's no reason this should be here, so this patch moves it to dwarf2read.h. gdb/ChangeLog 2019-05-08 Tom Tromey <tromey@adacore.com> * dwarf2loc.c: Include dwarf2read.h. * defs.h (read_unsigned_leb128): Don't declare. * dwarf2read.h (read_unsigned_leb128): Declare.
2019-05-08Fix build problem in fputs_maybe_filteredTom Tromey2-1/+6
When merging commit 99f20f ("Fix style bug when paging") to master, I had to make some changes to get it to compile again. Unfortunately, I must not have added these to the index at the correct time, because they were not committed. This patch fixes the problem. gdb/ChangeLog 2019-05-08 Tom Tromey <tromey@adacore.com> * utils.c (fputs_maybe_filtered): Call can_emit_style_escape as a method.
2019-05-08Fix style bug when pagingTom Tromey2-3/+26
Philippe pointed out a styling bug that would occur in some conditions when paging: https://sourceware.org/ml/gdb-patches/2019-04/msg00101.html I was finally able to reproduce this, and this patch fixes the bug. The problem occurred when text overflowed the line, causing a pagination prompt, but when no wrap column had been set. In this case, the current style was reset to show the prompt, but then not reset back to the previously applied style before emitting the rest of the line. The fix is to record the applied style in this case, and re-apply it afterward -- but only if the pager prompt was emitted, something that the existing style.exp pointed out on the first, more naive, version of the patch. Tested on x86-64 Fedora 29. gdb/ChangeLog 2019-05-08 Tom Tromey <tromey@adacore.com> * utils.c (fputs_maybe_filtered): Reset style after paging, even when no wrap column is set.
2019-05-08Correctly handle non-C-style arrays in c_get_stringTom Tromey4-4/+48
A user here noticed that the Python Value.string method did not work for Ada arrays. I tracked this down to an oddity in value_as_address -- namely, it calls coerce_array, but that function will not force array coercion when the language has c_style_arrays=false, as Ada does. This patch fixes the problem by changing c_get_string so that arrays take the "in GDB's memory" branch. The actual patch is somewhat more complicated than you might think, because the caller can request more array elements than the type allows. This is normal when the type is using the C struct hack. Tested on x86-64 Fedora 29. gdb/ChangeLog 2019-05-08 Tom Tromey <tromey@adacore.com> * c-lang.c (c_get_string): Handle non-C-style arrays. gdb/testsuite/ChangeLog 2019-05-08 Tom Tromey <tromey@adacore.com> * gdb.python/py-value.exp (test_value_in_inferior): Add Ada test.
2019-05-08Change ptype/o to print bit offsetTom Tromey6-42/+40
Consider this short C example: struct inner { unsigned x; unsigned y : 3; unsigned z : 3; }; struct outer { unsigned char o : 3; struct inner i __attribute__ ((packed)); }; When I use "ptype/o" on this, I get: (gdb) ptype/o struct outer /* offset | size */ type = struct outer { /* 0: 5 | 1 */ unsigned char o : 3; /* XXX 5-bit hole */ /* 1 | 8 */ struct inner { /* 1 | 4 */ unsigned int x; /* 5:29 | 4 */ unsigned int y : 3; /* 5:26 | 4 */ unsigned int z : 3; /* XXX 2-bit padding */ /* XXX 3-byte padding */ /* total size (bytes): 8 */ } i; /* total size (bytes): 9 */ } In the location of "o" ("0: 5"), the "5" means "there are 5 bits left relative to the size of the underlying type. I find this very difficult to follow. On irc, Sergio said that this choice came because it is what pahole does. However, I think it's not very useful, and maybe is just an artifact of the way that DW_AT_bit_offset was defined in DWARF 3. This patch changes ptype/o to print the offset of a bitfield in a more natural way, that is, using the bit number according to the platform's bit numbering. With this patch, the output is now: (gdb) ptype/o struct outer /* offset | size */ type = struct outer { /* 0: 0 | 1 */ unsigned char o : 3; /* XXX 5-bit hole */ /* 1 | 8 */ struct inner { /* 1 | 4 */ unsigned int x; /* 5: 0 | 4 */ unsigned int y : 3; /* 5: 3 | 4 */ unsigned int z : 3; /* XXX 2-bit padding */ /* XXX 3-byte padding */ /* total size (bytes): 8 */ } i; /* total size (bytes): 9 */ } This is better, IMO, because now the "offset" of a bitfield is consistent with the offset of an ordinary member, referring to its offset from the start of the structure. gdb/ChangeLog 2019-05-08 Tom Tromey <tromey@adacore.com> * typeprint.c (print_offset_data::update): Print the bit offset, not the number of bits remaining. gdb/doc/ChangeLog 2019-05-08 Tom Tromey <tromey@adacore.com> * gdb.texinfo (Symbols): Document change to ptype/o. gdb/testsuite/ChangeLog 2019-05-08 Tom Tromey <tromey@adacore.com> * gdb.base/ptype-offsets.exp: Update tests.
2019-05-08Fix ptype/o comment formattingTom Tromey5-253/+266
I noticed that ptype/o will print: /* 3: 3 | 1 */ signed char a4 : 2; /* XXX 3-bit hole */ That is, "*/" at the end of the "hole" message does not line up with the other comment ends. I thought it would be a bit nicer if this did line up, so I fixed it. Then, to my surprise, I found that I could not make ptype-offsets.exp fail. I still am not sure why it doesn't fail, but changing the tests to use string_to_regexp and changing the quoting helped. This in turn showed that some of the existing test cases were wrong, so I've also updated them here. gdb/ChangeLog 2019-05-08 Tom Tromey <tromey@adacore.com> * typeprint.c (print_offset_data::maybe_print_hole): Add extra padding at end of comment. gdb/testsuite/ChangeLog 2019-05-08 Tom Tromey <tromey@adacore.com> * gdb.base/ptype-offsets.exp: Use string_to_regexp. Fix test cases. * gdb.base/ptype-offsets.cc (struct abc) <my_int_type>: Now "short".
2019-05-08Fix VLA printing for AdaTom Tromey5-2/+111
While looking at a different Ada problem, I found that printing a record containing a VLA did not work properly. I tracked the problem down to dwarf2_evaluate_property trying, and failing, to compare two types that differed only in qualifiers. This patch changes dwarf2_evaluate_property to ignore qualifiers when comparing types. Tested on x86-64 Fedora 29. gdb/ChangeLog 2019-05-08 Tom Tromey <tromey@adacore.com> * dwarf2loc.c (dwarf2_evaluate_property) <PROP_ADDR_OFFSET>: Compare main types. gdb/testsuite/ChangeLog 2019-05-08 Tom Tromey <tromey@adacore.com> * gdb.ada/vla.exp: New file. * gdb.ada/vla/vla.adb: New file.
