2020-11-12gdb: add an option flag to 'maint print c-tdesc'Andrew Burgess7-81/+173
GDB has two approaches to generating the target descriptions found in gdb/features/, the whole description approach, where the XML file contains a complete target description which is then used to generate a single C file that builds that target description. Or, the split feature approach, where the XML files contain a single target feature, each feature results in a single C file to create that one feature, and then a manually written C file is used to build a complete target description from individual features. There's a Makefile, gdb/features/Makefile, which is responsible for managing the regeneration of the C files from the XML files. However, some of the logic that selects between the whole description approach, or the split feature approach, is actually hard-coded into GDB, inside target-descriptions.c:maint_print_c_tdesc_cmd we check the path to the incoming XML file and use this to choose which type of C file we should generate. This commit removes this hard coding from GDB, and makes the Makefile entirely responsible for choosing the approach. This makes sense as the Makefile already has the XML files partitioned based on which approach they should use. In order to allow this change the 'maint print c-tdesc' command is given a new command option '-single-feature', which tells GDB which type of C file should be created. The makefile now supplies this flag to GDB. This did reveal a bug in features/Makefile, the rx.xml file was in the wrong list, this didn't matter previously as the actual choice of which approach to use was done in GDB. Now the Makefile decides, so placing each XML file in the correct list is critical. Tested this by doing 'make GDB=/path/to/gdb clean-cfiles cfiles' to regenerate all the C files from their XML source. There are no changes after this commit. gdb/ChangeLog: * features/Makefile (XMLTOC): Add rx.xml. (FEATURE_XMLFILES): Remove rx.xml.

2020-11-11gdb/testsuite: add "breakpoint always-inserted" axis in ↵Simon Marchi2-3/+16
gdb.base/continue-after-aborted-step-over.exp The test gdb.base/continue-after-aborted-step-over.exp fails on ROCm GDB [1] when using the unix board (when debugging a standard x86-64/Linux program), with: (gdb) b *0^M Breakpoint 2 at 0x0^M Warning:^M Cannot insert breakpoint 2.^M Cannot access memory at address 0x0^M ^M (gdb) FAIL: gdb.base/continue-after-aborted-step-over.exp: displaced-stepping=off: b *0 This happens because that build of GDB defaults to "set breakpoint always-inserted on", for reasons that are unrelevant to explain here. As soon as the breakpoint is created, GDB tries to insert it and (expectedly) fails. This causes more text to be output than what the pattern expects. It is actually be relevant to run the test with both "set breakpoint always-inserted" on and off. With it on, it mimics what happens when running in non-stop mode, with other threads running. This is relevant for upstream even outside of the ROCm port, so here's a patch for it. Add this other axis and adjust the "b *0" test to handle the extra output when it is on.

2020-11-10Prevent false passes in gdb.base/vla-optimized-out.expGary Benson2-1/+6
The "vla_optimized_out" procedure in gdb.base/vla-optimized-out.exp accepts a "sizeof_result" argument which is substituted into the regular expression used to check the result of printing the sizeof a VLA. The -O3 test variants, however, pass a regular expression fragment as that argument, which expands into a regular expression that matches any result with a "6" in it. This commit wraps the substitution with parentheses to prevent these false matches. gdb/testsuite/ChangeLog: * gdb.base/vla-optimized-out.exp (p sizeof (a)): Wrap supplied regexp fragment in parentheses to prevent false matching.

2020-11-09RISC-V: Update ABI to the elf_flags after parsing elf attributes.Nelson Chu18-47/+211
Originally, if the -mabi option isn't set, then assembler will set the abi according to the architecture string in the riscv_after_parse_args. But we should also check and reset the abi later since the architecture string may be reset by the elf attributes. Therefore, set the abi to the elf_flags in the riscv_after_parse_args seems too early. Besides, we have to set the abi_xlen before assembling any instruction, so it should be safe to call riscv_set_abi_by_arch at the place that we set start_assemble to TRUE. However, one minor case is that we won't call the md_assemble when we are assembling an file without any instruction. It seems that we still need to set the abi in riscv_elf_final_processing, to make sure that abi can be updated according to the elf arch attributes. For the rv32i and most elf toolchains, this patch can fix the mis-matched ABI errors for Run pr26391-5 and Run pr26391-6 testcases. Besides, it also correct the elf header flags of the output objects. Consider the new testcases, mabi-fail-02 and mabi-noabi-attr-[01|02|03], they are failed before applying this patch. But I still get the mis-matched ABI errors for the following toolchains when runnung the riscv-gnu-toolchain regressions, newlib-rv32imafc-ilp32f-[medlow|medany] linux-rv32imac-ilp32-[medlow|medany] linux-rv32imafdc-ilp32-[medlow|medany} linux-rv64imac-lp64-[medlow|medany] linux-rv64imafdc-lp64-[medlow|medany} For the newlib-rv32imafc-ilp32f, although we try to choose the abi according to the elf attributes, we will use FLOAT_ABI_SOFT rather than the FLOAT_ABI_SINGLE for the assmebly file wihtout setting the -mabi, but compiler will set the abi to FLOAT_ABI_SINGLE for the C files. As for the linux toolchains, we also get fails for Run pr26391-5 and Run pr26391-6 testcases. Since the linux toolchain won't generate elf attributes to correct the ISA, and the --with-arch configure option isn't set, assembler will try to set the default arch to rv[32|64]g, which means the FLOAT_ABI_DOUBLE will be choosed, and may be conflict with the abi set by the toolchain. Therefore, I would suggest that it's is more safe to set the --with-arch when building binutils, but it may break some testcases. For example, ld-scripts/fill and ld-scripts/empty-address-2 may be broken when c-ext is set. We might insert R_RISCV_ALIGN to make sure the 4-byte alignment, but the dump result will be a bit different from what the testcase expected. However, this patch only fix the problem - the abi, elf_flags and the instruction, which is generated according to the abi_xlen, are all fixed once the elf attributes are set for most elf toolchains. Other mis-matched ABI problems should be fixed when we always build the binutils with the --with-arch= configure option. gas/ * config/tc-riscv.c (explicit_mabi): New boolean to indicate if the -mabi= option is explictly set.

Dump of expression @ 0x4eced60, after conversion to prefix form: Expression: `call_me (&main::val, VAL(Aborted (core dumped) The situation was even worse for Fortran function calls, or array indexes, which both make use of the same expression opcode. The problem was that in a couple of places the index into the expression array was handled incorrectly causing GDB to interpret elements incorrectly. These issues are fixed in this commit. There are already some tests to check GDB when 'set debug expression 1' is set, these can be found in gdb.*/debug-expr.exp. Unfortunately the cases above were not covered. In this commit I have cleaned up all of the debug-expr.exp files a little, there was a helper function that had clearly been copied into each file, this is now moved into lib/gdb.exp.

2020-11-06gdb/testsuite: make DWARF assembler's ranges' "base" and "range" procsSimon Marchi10-66/+74
When creating a .debug_ranges section using the testsuite's DWARF assembler, it currently looks like this: ranges { sequence { {base ...} {range ...} {range ...} } } The sub-tree of sequence is manually traversed as a list of lists. I think it would be nicer if `base` and `range` where procedure, just like the other levels: ranges { sequence { base ... range ... range ... } } That makes the implementation more robust, and the usage a bit nicer (less special characters). It also allows having comments in between the range list entries: ranges { sequence { base ... range ... # Hello world. range ... } } ... which doesn't work with the current approach. gdb/testsuite/ChangeLog: * lib/dwarf.exp (ranges): Handle "base" and "range" as proceduresu. * gdb.dwarf/dw2-bad-elf.exp: Adjust. * gdb.dwarf2/dw2-inline-many-frames.exp: Adjust. * gdb.dwarf2/dw2-inline-stepping.exp: Adjust. * gdb.dwarf2/dw2-ranges-base.exp: Adjust. * gdb.dwarf2/dw2-ranges-func.exp: Adjust. * gdb.dwarf2/dw2-ranges-overlap.exp: Adjust. * gdb.dwarf2/dw2-ranges-psym.exp: Adjust. * gdb.dwarf2/enqueued-cu-base-addr.exp: Adjust.

And like that assignment operator, we would assert that only shared buffers can be copied from. However, it is hard to see why only shared buffers need to be copied. I mean, it must be true, otherwise macro support would be broken, since currently GDB is relying on the default implementation of the copy constructor, which just copies the fields, which can't work correctly for the non-shared version. Still, it's not easy to tell from the code that that is indeed correct, that there isn't some corner case that would require copying a non-shared buffer. Or to put it simply - the tangling of shared and non-shared buffers in the same macro_buffer struct makes this structure hard to understand. My reaction was -- try splitting the macro_buffer class into two classes, one for non-shared buffers, and another for shared buffers. Comments and asserts like these: ... SRC must be a shared buffer; DEST must not be one. */ static void scan (struct macro_buffer *dest, struct macro_buffer *src, struct macro_name_list *no_loop, const macro_scope &scope) { gdb_assert (src->shared); gdb_assert (! dest->shared); ... made me suspect it should be possible. Then after the split it should be easier to reimplement either of the classes if we want. So I decided to try splitting the struct in two distinct types, and see where that leads. It turns out that there is really no good reason for a single struct, no code that wants to work with either shared or non-shared buffers. It's always shared for input being parsed, and non-shared for output. This commit is the result. I named the new classes shared_macro_buffer and growable_macro_buffer. A future direction could be for example to make shared_macro_buffer wrap a string_view and growable_macro_buffer a std::string. With that in mind, other than text/len, only the 'last_token' field is common to both classes. I didn't feel like creating a base class just for that single field. I constified shared_macro_buffer's 'text' field, which of course had some knock-on effects, fixed in the patch. On the original warning issued by Clang -- now it is clear that only the shared version needs to be copied. Since this class doesn't need a user-declared destructor, the default implementations of the copy assign/ctor can be used, and Clang no longer warns. The growable version doesn't need to be copied, so I disabled copy/assign for it. gdb/ChangeLog: * macroexp.c (struct macro_buffer): Split in two classes. Add uses adjusted. (struct shared_macro_buffer): New, factored out from struct macro_buffer. (struct growable_macro_buffer): New, factored out from struct macro_buffer. (set_token, get_comment, get_identifier, get_pp_number) (get_character_constant, get_string_literal, get_punctuator) (get_next_token_for_substitution): Constify parameters. (substitute_args): Constify locals. Change-Id: I5712e30e826d949715703b2e9172adf04e63b152

2020-11-05Remove objfile parameter from abbrev_table::readTom Tromey4-13/+26
In a longer series that I am working on, I needed to remove the objfile parameter from abbrev_table::read. It seemed to me that this was a simple and relatively harmless patch, so I'm sending it now. gdb/ChangeLog 2020-11-05 Tom Tromey <tom@tromey.com> * dwarf2/read.c (read_cutu_die_from_dwo) (cutu_reader::cutu_reader, cutu_reader::cutu_reader) (build_type_psymtabs_1): Update. * dwarf2/abbrev.h (struct abbrev_table): Remove objfile parameter. * dwarf2/abbrev.c (abbrev_table::read): Remove objfile parameter. Don't read section. Add assert.
