* ada-exp.y: Considerable reorganization to move functionality from ada-lex.l to here, where it is logically more appropriate. The original reason, however, was to prevent premature name lookups for selector names in record aggregates. (BLOCKNAME, TYPENAME, OBJECT_RENAMING): Remove; lexer now returns NAME for all of these. (VAR): New artificial token to clarify precedence rules. (OTHERS): New lexeme. (empty_stoken): New symbol. (%union): Remove ssym, voidval. (%type): Remove <voidval> type declarations. (syntax definitions): Add aggregates. Remove distinction between NAME, TYPENAME, BLOCKNAME, OBJECT_RENAMING. Rename some non-terminals to be closer to reference manual usage.

Return all NAMEs, BLOCKNAMEs, OBJECT_RENAMINGs, TYPENAMEs in yylval.sval (as simple strings). All name look-ups now handled in ada-exp.y. Introduce "::" (COLONCOLON) token and return as separate token. (processId): Change return convention. Comment. Leave leading "'" in place. (processString): New function.

Remove `expout*' globals from parser-defs.h This commit removes the "expout*" globals from our parser code, turning them into a structure that is passed when an expression needs to be evaluated. This is the initial step to make our parser less "globalized". This is mostly a mechanical patch, which creates a structure containing the "expout*" globals and then modify all the functions that handle them in order to take the structure as argument. It is big, and has been reviewed at least 4 times, so I think everything is covered.

Remove `expout*' globals from parser-defs.h This commit removes the "expout*" globals from our parser code, turning them into a structure that is passed when an expression needs to be evaluated. This is the initial step to make our parser less "globalized". This is mostly a mechanical patch, which creates a structure containing the "expout*" globals and then modify all the functions that handle them in order to take the structure as argument. It is big, and has been reviewed at least 4 times, so I think everything is covered.

Remove `expout*' globals from parser-defs.h This commit removes the "expout*" globals from our parser code, turning them into a structure that is passed when an expression needs to be evaluated. This is the initial step to make our parser less "globalized". This is mostly a mechanical patch, which creates a structure containing the "expout*" globals and then modify all the functions that handle them in order to take the structure as argument. It is big, and has been reviewed at least 4 times, so I think everything is covered.

Remove `expout*' globals from parser-defs.h This commit removes the "expout*" globals from our parser code, turning them into a structure that is passed when an expression needs to be evaluated. This is the initial step to make our parser less "globalized".

Remove `expout*' globals from parser-defs.h This commit removes the "expout*" globals from our parser code, turning them into a structure that is passed when an expression needs to be evaluated. This is the initial step to make our parser less "globalized". This is mostly a mechanical patch, which creates a structure containing the "expout*" globals and then modify all the functions that handle them in order to take the structure as argument. It is big, and has been reviewed at least 4 times, so I think everything is covered.

Target FP: Use target format throughout expression parsing When parsing floating-point literals, the language parsers currently use parse_float or some equivalent routine to parse the input string into a DOUBLEST, which is then stored within a OP_DOUBLE expression node. When evaluating the expression, the OP_DOUBLE is finally converted into a value in target format. On the other hand, *decimal* floating-point literals are parsed directly into target format and stored that way in a OP_DECFLOAT expression node. In order to eliminate the DOUBLEST, this patch therefore unifies the handling of binary and decimal floating- point literals and stores them both in target format within a new OP_FLOAT expression node, replacing both OP_DOUBLE and OP_DECFLOAT. In order to store literals in target format, the parse_float routine needs to know the type of the literal. All parsers therefore need to be changed to determine the appropriate type (e.g. by detecting suffixes) *before* calling parse_float, instead of after it as today. However, this change is mostly straightforward -- again, this is already done for decimal FP today. The core of the literal parsing is moved into a new routine floatformat_from_string, mirroring floatformat_to_string. The parse_float routine now calls either floatformat_from_string or decimal_from_sting, allowing it to handle any type of FP literal. All language parsers need to be updated. Some notes on specific changes to the various languages: - C: Decimal FP is now handled in parse_float, and no longer needs to be handled specially. - D: Straightforward. - Fortran: Still used a hard-coded "atof", also replaced by parse_float now. Continues to always use builtin_real_s8 as the type of literal, even though this is probably wrong. - Go: This used to handle "f" and "l" suffixes, even though the Go language actually doesn't support those. I kept this support for now -- maybe revisit later. Note the the GDB test suite for some reason actually *verifies* that GDB supports those unsupported suffixes ... - Pascal: Likewise -- this handles suffixes that are not supported in the language standard. - Modula-2: Like Fortran, used to use "atof". - Rust: Mostly straightforward, except for a unit-testing hitch. The code use to set a special "unit_testing" flag which would cause "rust_type" to always return NULL. This makes it not possible to encode a literal into target format (which type?). The reason for this flag appears to have been that during unit testing, there is no "rust_parser" context set up, which means no "gdbarch" is available to use its types. To fix this, I removed the unit_testing flag, and instead simply just set up a dummy rust_parser context during unit testing. - Ada: This used to check sizeof (DOUBLEST) to determine which type to use for floating-point literal. This seems questionable to begin with (since DOUBLEST is quite unrelated to target formats), and in any case we need to get rid of DOUBLEST.

Introduce lookup_name_info and generalize Ada's FULL/WILD name matching Summary: - This is preparation for supporting wild name matching on C++ too. - This is also preparation for TAB-completion fixes. - Makes symbol name matching (think strcmp_iw) be based on a per-language method. - Merges completion and non-completion name comparison (think language_ops::la_get_symbol_name_cmp generalized). - Avoid re-hashing lookup name multiple times - Centralizes preparing a name for lookup (Ada name encoding / C++ Demangling), both completion and non-completion. - Fixes Ada latent bug with verbatim name matches in expressions - Makes ada-lang.c use common|symtab.c completion code a bit more. Ada's wild matching basically means that "(gdb) break foo" will find all methods named "foo" in all packages. Translating to C++, it's roughly the same as saying that "break klass::method" sets breakpoints on all "klass::method" methods of all classes, no matter the namespace. A following patch will teach GDB about fullname vs wild matching for C++ too. This patch is preparatory work to get there. Another idea here is to do symbol name matching based on the symbol language's algorithm. I.e., avoid dependency on current language set. This allows for example doing (gdb) b foo::bar< int > (<tab> and having gdb name match the C++ symbols correctly even if the current language is C or Assembly (or Rust, or Ada, or ...), which can easily happen if you step into an Assembly/C runtime library frame. By encapsulating all the information related to a lookup name in a class, we can also cache hash computation for a given language in the lookup name object, to avoid recomputing it over and over. Similarly, because we don't really know upfront which languages the lookup name will be matched against, for each language we store the lookup name transformed into a search name. E.g., for C++, that means demangling the name. But for Ada, it means encoding the name. This actually forces us to centralize all the different lookup name encoding in a central place, resulting in clearer code, IMO. See e.g., the new ada_lookup_name_info class. The lookup name -> symbol search name computation is also done only once per language. The old language->la_get_symbol_name_cmp / symbol_name_cmp_ftype are generalized to work with both completion, and normal symbol look up. At some point early on, I had separate completion vs non-completion language vector entry points, but a single method ends up being better IMO for simplifying things -- the more we merge the completion / non-completion name lookup code paths, the less changes for bugs causing completion vs normal lookup finding different symbols. The ada-lex.l change is necessary because when doing (gdb) p <UpperCase> then the name that is passed to write_ write_var_or_type -> ada_lookup_symbol_list misses the "<>", i.e., it's just "UpperCase", and we end up doing a wild match against "UpperCase" lowercased by ada_lookup_name_info's constructor. I.e., "uppercase" wouldn't ever match "UpperCase", and the symbol lookup fails. This wouldn't cause any regression in the testsuite, but I added a new test that would pass before the patch and fail after, if it weren't for that fix. This is latent bug that happens to go unnoticed because that particular path was inconsistent with the rest of Ada symbol lookup by not lowercasing the lookup name. Ada's symbol_completion_add is deleted, replaced by using common code's completion_list_add_name. To make the latter work for Ada, we needed to add a new output parameter, because Ada wants to return back a custom completion candidates that are not the symbol name. With this patch, minimal symbol demangled name hashing is made consistent with regular symbol hashing. I.e., it now goes via the language vector's search_name_hash method too, as I had suggested in a previous patch. dw2_expand_symtabs_matching / .gdb_index symbol names were a challenge. The problem is that we have no way to telling what is the language of each symbol name found in the index, until we expand the corresponding full symbol, which is off course what we're trying to avoid. Language information is simply not considered in the index format... Since the symbol name hashing and comparison routines are per-language, we now have a problem. The patch sorts this out by matching each name against all languages. This is inneficient, and indeed slows down completion several times. E.g., with: $ cat script.cmd set pagination off set $count = 0 while $count < 400 complete b string_prin printf "count = %d\n", $count set $count = $count + 1 end $ time gdb --batch -q ./gdb-with-index -ex "source script-string_printf.cmd" I get, before patch (-O2, x86-64): real 0m1.773s user 0m1.737s sys 0m0.040s While after patch (-O2, x86-64): real 0m9.843s user 0m9.482s sys 0m0.034s However, the following patch will optimize this, and will actually make this use case faster compared to the "before patch" above: real 0m1.321s user 0m1.285s sys 0m0.039s gdb/ChangeLog: 2017-11-08 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_encode): Rename to ..

from NAME0 in that:
Introduce lookup_name_info and generalize Ada's FULL/WILD name matching Summary: - This is preparation for supporting wild name matching on C++ too. - This is also preparation for TAB-completion fixes. - Makes symbol name matching (think strcmp_iw) be based on a per-language method. - Merges completion and non-completion name comparison (think language_ops::la_get_symbol_name_cmp generalized). - Avoid re-hashing lookup name multiple times - Centralizes preparing a name for lookup (Ada name encoding / C++ Demangling), both completion and non-completion. - Fixes Ada latent bug with verbatim name matches in expressions - Makes ada-lang.c use common|symtab.c completion code a bit more. Ada's wild matching basically means that "(gdb) break foo" will find all methods named "foo" in all packages. Translating to C++, it's roughly the same as saying that "break klass::method" sets breakpoints on all "klass::method" methods of all classes, no matter the namespace. A following patch will teach GDB about fullname vs wild matching for C++ too. This patch is preparatory work to get there. Another idea here is to do symbol name matching based on the symbol language's algorithm. I.e., avoid dependency on current language set. This allows for example doing (gdb) b foo::bar< int > (<tab> and having gdb name match the C++ symbols correctly even if the current language is C or Assembly (or Rust, or Ada, or ...), which can easily happen if you step into an Assembly/C runtime library frame. By encapsulating all the information related to a lookup name in a class, we can also cache hash computation for a given language in the lookup name object, to avoid recomputing it over and over. Similarly, because we don't really know upfront which languages the lookup name will be matched against, for each language we store the lookup name transformed into a search name. E.g., for C++, that means demangling the name. But for Ada, it means encoding the name. This actually forces us to centralize all the different lookup name encoding in a central place, resulting in clearer code, IMO. See e.g., the new ada_lookup_name_info class. The lookup name -> symbol search name computation is also done only once per language. The old language->la_get_symbol_name_cmp / symbol_name_cmp_ftype are generalized to work with both completion, and normal symbol look up. At some point early on, I had separate completion vs non-completion language vector entry points, but a single method ends up being better IMO for simplifying things -- the more we merge the completion / non-completion name lookup code paths, the less changes for bugs causing completion vs normal lookup finding different symbols. The ada-lex.l change is necessary because when doing (gdb) p <UpperCase> then the name that is passed to write_ write_var_or_type -> ada_lookup_symbol_list misses the "<>", i.e., it's just "UpperCase", and we end up doing a wild match against "UpperCase" lowercased by ada_lookup_name_info's constructor. I.e., "uppercase" wouldn't ever match "UpperCase", and the symbol lookup fails. This wouldn't cause any regression in the testsuite, but I added a new test that would pass before the patch and fail after, if it weren't for that fix. This is latent bug that happens to go unnoticed because that particular path was inconsistent with the rest of Ada symbol lookup by not lowercasing the lookup name. Ada's symbol_completion_add is deleted, replaced by using common code's completion_list_add_name. To make the latter work for Ada, we needed to add a new output parameter, because Ada wants to return back a custom completion candidates that are not the symbol name. With this patch, minimal symbol demangled name hashing is made consistent with regular symbol hashing. I.e., it now goes via the language vector's search_name_hash method too, as I had suggested in a previous patch. dw2_expand_symtabs_matching / .gdb_index symbol names were a challenge. The problem is that we have no way to telling what is the language of each symbol name found in the index, until we expand the corresponding full symbol, which is off course what we're trying to avoid. Language information is simply not considered in the index format... Since the symbol name hashing and comparison routines are per-language, we now have a problem. The patch sorts this out by matching each name against all languages. This is inneficient, and indeed slows down completion several times. E.g., with: $ cat script.cmd set pagination off set $count = 0 while $count < 400 complete b string_prin printf "count = %d\n", $count set $count = $count + 1 end $ time gdb --batch -q ./gdb-with-index -ex "source script-string_printf.cmd" I get, before patch (-O2, x86-64): real 0m1.773s user 0m1.737s sys 0m0.040s While after patch (-O2, x86-64): real 0m9.843s user 0m9.482s sys 0m0.034s However, the following patch will optimize this, and will actually make this use case faster compared to the "before patch" above: real 0m1.321s user 0m1.285s sys 0m0.039s gdb/ChangeLog: 2017-11-08 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_encode): Rename to ..

In C++, we need to add an explicit cast when assigning the result to a pointer to another type (which is the case more often than not). The content of this patch is taken from Pedro's branch, from commit "(mostly) auto-generated patch to insert casts needed for C++". I validated that the changes make sense and manually reflowed the code to make it respect the coding style. I also found multiple places where I could use XNEW/XNEWVEC/XRESIZEVEC/etc. Thanks a lot to whoever did that automated script to insert casts, doing it completely by hand would have taken a ridiculous amount of time. Only files built on x86 with --enable-targets=all are modified. This means that all other -nat.c files are untouched and will have to be dealt with later by using appropiate compilers. Or maybe we can try to build them with a regular g++ just to know where to add casts, I don't know. I built-tested this with --enable-targets=all and reg-tested. Here's the changelog entry, which was not too bad to make despite the size, thanks to David Malcom's script. I fixed some bits by hand, but there might be some wrong parts left (hopefully not). gdb/ChangeLog: * aarch64-linux-tdep.c (aarch64_stap_parse_special_token): Add cast to allocation result assignment. * ada-exp.y (write_object_renaming): Likewise.

* ada-exp.y: Considerable reorganization to move functionality from ada-lex.l to here, where it is logically more appropriate. The original reason, however, was to prevent premature name lookups for selector names in record aggregates. (BLOCKNAME, TYPENAME, OBJECT_RENAMING): Remove; lexer now returns NAME for all of these. (VAR): New artificial token to clarify precedence rules. (OTHERS): New lexeme. (empty_stoken): New symbol. (%union): Remove ssym, voidval. (%type): Remove <voidval> type declarations. (syntax definitions): Add aggregates. Remove distinction between NAME, TYPENAME, BLOCKNAME, OBJECT_RENAMING. Rename some non-terminals to be closer to reference manual usage. Tighten up expression syntax to disallow certain non-Ada constructions such as X and then Y or else Z. (ada_parse): Remove initialization of left_block_context. (write_var_from_name): Remove. (write_var_or_type): New function, containing previous code from defunct write_var_from_name and name_lookup. (block_lookup): New function, moved from ada-lex.l (select_possible_type_sym): New function, factored out of name_lookup, which used to be in ada-lex.l. (find_primitive_type): Ditto. (chop_selector): Ditto. (write_ambiguous_var): New function, factored out of defunct write_var_from_name. (write_selectors): New function. (write_name_assoc): New function. (write_exp_op_with_string): New function. * ada-lex.l (processId): Change interface to return stoken. (tempbuf, resize_tempbuf, tempbuf_size, tempbuf_len): Remove. (block_lookup, name_lookup): Remove. Functionality moved to ada-exp.y. (state IN_STRING): Remove. (rules): Handle string escapes in processString. Add 'others' token. Return all NAMEs, BLOCKNAMEs, OBJECT_RENAMINGs, TYPENAMEs in yylval.sval (as simple strings). All name look-ups now handled in ada-exp.y. Introduce "::" (COLONCOLON) token and return as separate token. (processId): Change return convention. Comment. Leave leading "'" in place. (processString): New function. (find_dot_all): Add note to comment. Fix problem that allowed match only at the end. * ada-lang.c: Introduce aggregates. (find_struct_field): Add new parameter to count fields skipped, and allow other output parameters to be NULL. (value_tag_from_contents_and_address, ada_value_struct_elt): Use new find_struct_field. (ada_index_struct_field, assign_aggregate, ada_is_array_type) (num_visible_fields, ada_index_struct_field_1, ada_index_struct_field) (num_component_specs, assign_component, assign_aggregate): (aggregate_assign_from_choices,aggregate_assign_positional) (aggregate_assign_others,add_component_interval): New functions. (ada_evaluate_subexp): Declare. Add aggregate-related operators. (ada_forward_operator_length): Declare. (resolve_subexp): Add cases for new aggregate operators and OP_NAME. Consolidate Ada operators, using ada_forward_operator_length. (ada_search_struct_field): Search in forward order. (ADA_OPERATORS): Add new aggregate operators.

Introduce lookup_name_info and generalize Ada's FULL/WILD name matching Summary: - This is preparation for supporting wild name matching on C++ too. - This is also preparation for TAB-completion fixes. - Makes symbol name matching (think strcmp_iw) be based on a per-language method. - Merges completion and non-completion name comparison (think language_ops::la_get_symbol_name_cmp generalized). - Avoid re-hashing lookup name multiple times - Centralizes preparing a name for lookup (Ada name encoding / C++ Demangling), both completion and non-completion. - Fixes Ada latent bug with verbatim name matches in expressions - Makes ada-lang.c use common|symtab.c completion code a bit more. Ada's wild matching basically means that "(gdb) break foo" will find all methods named "foo" in all packages. Translating to C++, it's roughly the same as saying that "break klass::method" sets breakpoints on all "klass::method" methods of all classes, no matter the namespace. A following patch will teach GDB about fullname vs wild matching for C++ too. This patch is preparatory work to get there. Another idea here is to do symbol name matching based on the symbol language's algorithm. I.e., avoid dependency on current language set. This allows for example doing (gdb) b foo::bar< int > (<tab> and having gdb name match the C++ symbols correctly even if the current language is C or Assembly (or Rust, or Ada, or ...), which can easily happen if you step into an Assembly/C runtime library frame. By encapsulating all the information related to a lookup name in a class, we can also cache hash computation for a given language in the lookup name object, to avoid recomputing it over and over. Similarly, because we don't really know upfront which languages the lookup name will be matched against, for each language we store the lookup name transformed into a search name. E.g., for C++, that means demangling the name. But for Ada, it means encoding the name. This actually forces us to centralize all the different lookup name encoding in a central place, resulting in clearer code, IMO. See e.g., the new ada_lookup_name_info class. The lookup name -> symbol search name computation is also done only once per language. The old language->la_get_symbol_name_cmp / symbol_name_cmp_ftype are generalized to work with both completion, and normal symbol look up. At some point early on, I had separate completion vs non-completion language vector entry points, but a single method ends up being better IMO for simplifying things -- the more we merge the completion / non-completion name lookup code paths, the less changes for bugs causing completion vs normal lookup finding different symbols. The ada-lex.l change is necessary because when doing (gdb) p <UpperCase> then the name that is passed to write_ write_var_or_type -> ada_lookup_symbol_list misses the "<>", i.e., it's just "UpperCase", and we end up doing a wild match against "UpperCase" lowercased by ada_lookup_name_info's constructor. I.e., "uppercase" wouldn't ever match "UpperCase", and the symbol lookup fails. This wouldn't cause any regression in the testsuite, but I added a new test that would pass before the patch and fail after, if it weren't for that fix. This is latent bug that happens to go unnoticed because that particular path was inconsistent with the rest of Ada symbol lookup by not lowercasing the lookup name. Ada's symbol_completion_add is deleted, replaced by using common code's completion_list_add_name. To make the latter work for Ada, we needed to add a new output parameter, because Ada wants to return back a custom completion candidates that are not the symbol name. With this patch, minimal symbol demangled name hashing is made consistent with regular symbol hashing. I.e., it now goes via the language vector's search_name_hash method too, as I had suggested in a previous patch. dw2_expand_symtabs_matching / .gdb_index symbol names were a challenge. The problem is that we have no way to telling what is the language of each symbol name found in the index, until we expand the corresponding full symbol, which is off course what we're trying to avoid. Language information is simply not considered in the index format... Since the symbol name hashing and comparison routines are per-language, we now have a problem. The patch sorts this out by matching each name against all languages. This is inneficient, and indeed slows down completion several times. E.g., with: $ cat script.cmd set pagination off set $count = 0 while $count < 400 complete b string_prin printf "count = %d\n", $count set $count = $count + 1 end $ time gdb --batch -q ./gdb-with-index -ex "source script-string_printf.cmd" I get, before patch (-O2, x86-64): real 0m1.773s user 0m1.737s sys 0m0.040s While after patch (-O2, x86-64): real 0m9.843s user 0m9.482s sys 0m0.034s However, the following patch will optimize this, and will actually make this use case faster compared to the "before patch" above: real 0m1.321s user 0m1.285s sys 0m0.039s gdb/ChangeLog: 2017-11-08 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_encode): Rename to ..

Add casts to memory allocation related calls Most allocation functions (if not all) return a void* pointing to the allocated memory. In C++, we need to add an explicit cast when assigning the result to a pointer to another type (which is the case more often than not). The content of this patch is taken from Pedro's branch, from commit "(mostly) auto-generated patch to insert casts needed for C++". I validated that the changes make sense and manually reflowed the code to make it respect the coding style. I also found multiple places where I could use XNEW/XNEWVEC/XRESIZEVEC/etc. Thanks a lot to whoever did that automated script to insert casts, doing it completely by hand would have taken a ridiculous amount of time. Only files built on x86 with --enable-targets=all are modified. This means that all other -nat.c files are untouched and will have to be dealt with later by using appropiate compilers. Or maybe we can try to build them with a regular g++ just to know where to add casts, I don't know. I built-tested this with --enable-targets=all and reg-tested. Here's the changelog entry, which was not too bad to make despite the size, thanks to David Malcom's script.

Note: we actually don't need this routine, since 'all' can never be an
Ada identifier. Thus, looking up foo.all or foo.all.x as a name
must fail, and will eventually be interpreted as (foo).all or
(foo).all.x. However, this does avoid an extraneous lookup. */
