2019-12-19Consistently quote variables used with "test"Christian Biesinger7-72/+83
This ensures that empty variables and variables with spaces are handled correctly. Code was inconsistent on whether the constant string (e.g. yes/no) should also be quoted; I tried to be consistent with surrounding code. This fixes the error Eli reported during configure with mingw (though that was not fatal). gdb/ChangeLog: 2019-12-19 Christian Biesinger <cbiesinger@google.com> * configure: Regenerate. * configure.ac: Quote variable arguments of test. * gdbsupport/common.m4: Likewise. gdb/gdbserver/ChangeLog: 2019-12-19 Christian Biesinger <cbiesinger@google.com> * configure: Regenerate. * configure.ac: Quote variable arguments of test.

2019-12-19Fix build with GNU Make 3.81Bernd Edlinger2-4/+8
GNU Make 3.81 is apparently confused when the same source file is processed by a pattern rule and an explicit rule at the same time with different output file. The pattern %.o: ../%.c and alloc-ipa.o: ../alloc.c both have the source ../alloc.c but two independent object files alloc.o and alloc-ipa.o, so while building gdbserver I see the following message: make[4]: Circular alloc-ipa.o <- ../alloc.c dependency dropped. CXX alloc-ipa.o g++: warning: '-x c++' after last input file has no effect g++: fatal error: no input files compilation terminated. In the make debug output I see the pattern is first correct: alloc-ipa.o: ../alloc.c | config.h build-gnulib-gdbserver/import/string.h $(IPAGENT_COMPILE) $(WARN_CFLAGS_NO_FORMAT) $< $(POSTCOMPILE) But after the "Circular" dependency is dropped, the pattern is changed to: alloc-ipa.o: | config.h build-gnulib-gdbserver/import/string.h $(IPAGENT_COMPILE) $(WARN_CFLAGS_NO_FORMAT) $< $(POSTCOMPILE) So indeed now $< is empty, and the build step fails. This happens only when alloc.o needs to be built, when alloc.o was already built, the build succeeds, but it takes often several attempts until the build succeeds. By rewriting the alloc-ipa.c: ../alloc.c rule into a pattern rule, the problem goes away. While already at it, this patch removes also the $(WARN_CFLAGS_NO_FORMAT) from the build rule, which is just a copy/paste thing that is not necessary for alloc.c at all.
2019-12-19Make the literal argument to pow a double, not an integerChristian Biesinger2-2/+9
Since pow takes doubles, pass 2.0 instead of 2 to pow (). Conveniently, this fixes the ambiguous call to pow on Solaris 11 with gcc 5.5 (gcc211 on the compile farm), which has a "using std::pow" directive in a system header, which brings in float/double/long double overloads. Fixes the build on Solaris with enable-targets=all. gdb/ChangeLog: 2019-12-19 Christian Biesinger <cbiesinger@google.com> * score-tdep.c (score7_analyze_prologue): Pass 2.0 instead of 2 to pow ().

2019-12-19Cast the log10 argument to double to disambiguate itChristian Biesinger2-1/+8
On Solaris 11 with gcc 5.5.0 (gcc211 on the compile farm), math.h has a using std::log10; directive. This is unfortunate because std::log10 has overloads for float/double/long double. To disambiguate this call, cast the argument to double to fix the build. gdb/ChangeLog: 2019-12-19 Christian Biesinger <cbiesinger@google.com> * tui/tui-source.c (tui_source_window::set_contents): Cast argument of log10 to double to fix Solaris 11 with gcc 5.5.

2019-12-19Handle CRLF when reading XML on WindowsTom Tromey4-5/+22
xml-support.c uses FOPEN_RT, but then reads the entire contents of the file and verifies that the number of bytes read matches the length. This can fail on Windows, where the read will translate line terminators. This patch fixes the bug by changing xml-support.c to use FOPEN_RB. This works because expat correctly handles \r\n line terminators. gdb/ChangeLog 2019-12-11 Tom Tromey <tromey@adacore.com> * xml-support.c (xml_fetch_content_from_file): Use FOPEN_RB. gdb/testsuite/ChangeLog 2019-12-11 Tom Tromey <tromey@adacore.com> * gdb.xml/tdesc-arch.exp (set_arch): Add "trans_mode" parameter.

2019-12-18Fix pthread_setname_np build errorTom Tromey2-1/+9
My earlier patch to fix the pthread_setname_np build error on macOS was incorrect. While the macOS man page claims that pthread_setname_np returns void, in <pthread.h> it is actually declared returning "int". I knew this earlier, but must have made some mistake when preparing the patch for submission (perhaps when removing the templates?). This patch re-fixes the bug.

I'm not sure how clang translates that to misleading indentation, but making the indentation correct gets rid of the error.

2019-12-18Fix build failure on macOSTom Tromey3-6/+18
PR build/25250 notes that the gdb 9 pre-release fails to build on macOS, due to a name clash between field_kind::STRING and the STRING token in ada-exp.y. I am not sure (I couldn't reproduce this myself), but presumably this is due to differences caused by the version of bison in use there. This patch works around the problem by renaming the field_kind enumerator. I chose to rename this one because it is used in relatively few places -- it's just an implementation detail of the style code. This version also renames field_kind::SIGNED for consistency. Let me know what you think.

2019-12-18More signed overflow fixesAlan Modra12-59/+70
The arc fix in create_map avoiding signed overflow by casting an unsigned char to unsigned int before shifting, shows one of the dangers of blinding doing that. The problem in this case was that the variable storing the value, newAuxRegister->address, was a long. Using the unsigned cast meant that the 32-bit value was zero extended when long is 64 bits. Previously we had a sign extension. Net result was that comparisons in arcExtMap_auxRegName didn't match. Of course, I could have cast the 32-bit unsigned value back to signed before storing in a long, but it's neater to just use an unsigned int for the address. opcodes/ * alpha-opc.c (OP): Avoid signed overflow. * arm-dis.c (print_insn): Likewise. * mcore-dis.c (print_insn_mcore): Likewise. * pj-dis.c (get_int): Likewise. * ppc-opc.c (EBD15, EBD15BI): Likewise. * score7-dis.c (s7_print_insn): Likewise. * tic30-dis.c (print_insn_tic30): Likewise. * v850-opc.c (insert_SELID): Likewise. * vax-dis.c (print_insn_vax): Likewise. * arc-ext.c (create_map): Likewise.

We allocate a derived object (tui_layout_split), but delete it through a tui_layout_base pointer.

2019-12-17Fix skip.exp test failure observed with gcc-9.2.0Bernd Edlinger2-5/+15
We need to step a second time with this gcc version. The first step jumps back to main before entering foo. Previously the control flow was from bar directly to foo. Further ananlysis suggests, that this change in behavior started with gcc-8.1.0 when -gcolumn-info was enabled by default. The option -gcolumn-info was first implemented in gcc-7.1.0 but default-disabled, so you can get the altered behavior already with gcc-7 if you manually enable -gcolumn-info. Previously there was just one point where line 30 (of skip.c) started: [0x00000032] Advance Line by 27 to 28 [0x00000034] Copy [0x00000035] Special opcode 63: advance Address by 4 to 0x4004cb and Line by 2 to 30 [0x00000036] Advance PC by constant 17 to 0x4004dc [0x00000037] Special opcode 7: advance Address by 0 to 0x4004dc and Line by 2 to 32 But with -gcolumn-info enabled, we have line 30 three times with different column: [0x00000034] Advance Line by 27 to 28 [0x00000036] Copy [0x00000037] Set column to 9 [0x00000039] Special opcode 63: advance Address by 4 to 0x4004c6 and Line by 2 to 30 [0x0000003a] Set column to 17 [0x0000003c] Special opcode 75: advance Address by 5 to 0x4004cb and Line by 0 to 30 [0x0000003d] Set column to 3 [0x0000003f] Special opcode 75: advance Address by 5 to 0x4004d0 and Line by 0 to 30 [0x00000040] Special opcode 105: advance Address by 7 to 0x4004d7 and Line by 2 to 32 That could probably be filtered in dwarf2read.c to keep the old behavior, but the new behavior makes still sense, even if we cannot really make use of the column in the line number info for now.

2019-12-17Prefer object over notype symbols when disassemblingAlan Modra43-41/+164
Changing objdump disassembly output like this always requires some testsuite changes, with the avr and x64_64 changes simply due to picking up better symbols, the whole point of the patch. The mips changes are due to mips-sgi-irix changing STT_NOTYPE symbols to STT_OBJECT, which objdump now chooses in preference to script symbols. The problem is that objdump looks at the first symbol in the section being disassembled, and if object type, just dumps out bytes rather than disassembling. This results in new failures: FAIL: JAL overflow 2 FAIL: undefined weak symbol overflow FAIL: undefined weak symbol overflow (n32) FAIL: undefined weak symbol overflow (n64) So for mips-sgi-irix function symbols really do need to be function type. I fixed a few more than just the required minimum to avoid the above test fails. binutils/ * objdump.c (compare_section): New static var. (compare_symbols): Sort by current section only.

2019-12-17Accept mips-sgi-irix output in a few ld testsAlan Modra6-13/+26
mips-sgi-irix gas emits STT_OBJECT symbols where other assemblers would use STT_NOTYPE. See mips_frob_symbol in gas/config/tc-mips.c. Also, the section of some dynamic symbols is set to SHN_MIPS_TEXT or SHN_MIPS_DATA. See _bfd_mips_elf_finish_dynamic_symbol in bfd/elfxx-mips.c. These differences are visible in readelf output and cause some tests to fail for no other good reason. The patch fixes the following fails and removes an xfail.

2019-12-16jit: make gdb_symtab::blocks an std::forward_listSimon Marchi2-94/+54
This patch changes the gdb_symtab::blocks manually maintained linked list to be an std::forward_list, simplifying memory management. Currently, the list is sorted as blocks are created. With an std::forward_list, it is easier (and probably a bit more efficient) to sort them once at the end, so this is what I did. A note about the comment on the "next" field: /* gdb_blocks are linked into a tree structure. Next points to the next node at the same depth as this block and parent to the parent gdb_block. */ I don't think it's true that "next" points to the next node at the same depth. All nodes are in a simple singly linked list, so necessarily some node will point to some other node that isn't at the same depth. gdb/ChangeLog: * jit.c (struct gdb_block) <next>: Remove field. (struct gdb_symtab) <~gdb_symtab>: Remove. <blocks>: Change type to std::forward_list<gdb_block>. (compare_block): Remove. (jit_block_open_impl): Adjust to std::forward_list. Place the new block at the beginning, don't mind about sorting. (finalize_symtab): Adjust to std::forward_list, sort the blocks list before using it.

It changes the fields to use automatic memory management, in the form of std::string and gdb::unique_xmalloc_ptr, and adds a constructor and a destructor. gdb/ChangeLog: * jit.c (struct gdb_symtab): Add constructor, destructor, initialize fields. <linetable>: Change type to unique_xmalloc_ptr. <file_name>: Change type to std::string. (jit_symtab_open_impl): Allocate gdb_symtab with new. (jit_symtab_line_mapping_add_impl): Adjust. (finalize_symtab): Adjust, call delete on stab.
2019-12-16Fix double-free when creating more than one block in JIT debug info readerSimon Marchi7-31/+104
A double-free happens when using a JIT debug info reader that creates more than one block. In the loop that frees blocks in finalize_symtab, at the very end, the gdb_block_iter_tmp variable is set initially, but not changed as the loop advances. If we have two blocks, the first iteration frees the first block, the second iteration frees the second block, but the third iteration tries to free the second block again, as gdb_block_iter_tmp keeps pointing on the second block. Fix it by assigning the gdb_block_iter_tmp variable in the loop. I have improved the jit-reader.exp test to cover this case, by adding a second "JIT-ed" function and creating a block for it. I have renamed the existing function to something I find a bit more descriptive. There are no significant changes to jit-reader.exp itself, only updates following the renaming. The important changes are in jithost.c (generate a new function) and in jitreader.c (create a gdb_block for that function). This was found because of an ASan report: $ ./gdb testsuite/outputs/gdb.base/jit-reader/jit-reader -ex "jit-reader-load /home/simark/build/binutils-gdb/gdb/testsuite/outputs/gdb.base/jit-reader/jitreader.so" -ex r Reading symbols from testsuite/outputs/gdb.base/jit-reader/jit-reader...
