Checks for insn alignment were hopelessly confused when misaligned data starts a new frag.

2018-02-07Fix type of values representing optimized out static membersSimon Marchi4-5/+15
As reported here: https://sourceware.org/ml/gdb/2018-02/msg00019.html the type of values representing static members that are optimized out is wrong. It currently assigns the type of the containing class rather than the type of the field. This patch fixes that. I found a place in m-static.exp already dealing with optimized out static members, so I just added some gdb_test there. gdb/ChangeLog: * value.c (value_static_field): Assign field type instead of containing type when returning an optimized out value. gdb/testsuite/ChangeLog: * gdb.cp/m-static.exp: Check type of optimized out static member.

GCC 8 will bring a new warning option which will detect possible overflow and truncation on string manipulation functions. For more details, see: https://gcc.gnu.org/ml/gcc-patches/2017-08/msg00471.html While compiling BFD with it, I can see one place on bfd/coff-rs6000.c where the warning is triggered. This: (void) strncpy (fhdr.magic, XCOFFARMAG, SXCOFFARMAG); will not include the trailing NUL on fhdr.magic, but that's fine because it's a magic number. The fix is trivial: just use memcpy instead.

2018-02-06Allow the find_abstract_instance_name() function in the BFD library to also ↵Paul Carroll2-10/+27
return file and line number information. The nm utility supports -l for using debug information to obtain file and line information for each symbol, if available. We have a tool that consumes this information and displays it. This identified a problem with the 'nm' utility. When a source is compiled with -O2, functions can be inlined. The compiler also produces an uninlined copy of the function, normally for linking to other object files. In the case of DWARF2 debug information, the compiler generates debug information to describe a function. If that function is inlined, the compiler then references that debug information from the inlined and uninlined copies of the routine through the use of the DW_AT_abstract_origin reference. When nm is used on such a file, it is not able to find file and line information because that information is present in the common debug information and not at each actual implementation of the function. The 'nm' utility only retrieves the name of the function from the abstract origin debug information and no more. What I am proposing is to modify the find_abstract_instance_name() function (which I renamed to find_abstract_instance() ) to return the name of the function as well as any file and line information. The routine is already parsing all of the debug information in the abstract instance, so it is easy to pick up the file and line information at that time. If, for some reason, the file and line information is not present, the routine behaves as before. For example, if I have a simple test case: int foo(int j) { if (j < 15) j += j << 2; else j += j << 6; return j; } int main (int argc,char **argv) { int i = argc; i += foo(i); return i; } If that test case is compiled with -O2 and then 'nm -l' reads that executable, it currently produces this symbol output (ignoring a lot of library symbols): 8048400 T foo 080482e0 T main /scratch/pcarroll/its254/test/mytest.c:12 If I modify 'nm' to return file and line information for abstract instances, it produces the following output: 08048400 T foo /scratch/pcarroll/its254/test/mytest.c:1 080482e0 T main /scratch/pcarroll/its254/test/mytest.c:12 -------------------------------------------------------------------------- bfd * bfd/dwarf2.c (find_abstract_name): Modified to return file and line information in addition to name, if they can be found.

2018-02-05ELF/BFD: Propagate the return status from backend section processingMaciej W. Rozycki2-1/+7
Fix the issue of any failure from `->elf_backend_section_processing' not being propagated by `_bfd_elf_write_object_contents'. The MIPS `_bfd_mips_elf_section_processing' handler can actually potentially fail, however the caller currently ignores that. bfd/ * elf.c (_bfd_elf_write_object_contents): Propagate a failure status from `->elf_backend_section_processing'.
2018-02-05binutils/testsuite: Support stderr options with `run_dump_test'Maciej W. Rozycki3-43/+157
Add support for the `error', `error_output', `warning' and `warning_output' options for `run_dump_test' input files, based on the version of the procedure in ld/testsuite/lib/ld-lib.exp and providing compatible semantics. These options apply to PROG under test and let test cases specify output expected on stderr as well as express a requirement for PROG to exit unsuccessfully. Messages to match against can be supplied either inline or fetched from a named file. Update procedure description in the introductory comment accordingly. As the exit status from `remote_exec' is regrettably lost in our default implementation of `binutils_run', which is user-overridable, avoid changing this procedure's API and use a global `binutils_run_status' variable to pass the status up to the caller, similarly to how `binutils_run_failed' is handled. Document the new variable in the respective introductory comments. binutils/ * testsuite/config/default.exp (binutils_run): Document `binutils_run_status'. * testsuite/lib/utils-lib.exp (default_binutils_run): Likewise, and set it. (run_dump_test): Add `error', `error_output', `warning' and `warning_output' options. Update documentation accordingly.

2018-02-05Align natural-format register values to the same columnRuslan Kabatsayev2-10/+36
Currently, commands such as "info reg", "info all-reg", as well as register window in the TUI print badly aligned columns, like here: eax 0x1 1 ecx 0xffffd3e0 -11296 edx 0xffffd404 -11260 ebx 0xf7fa5ff4 -134586380 esp 0xffffd390 0xffffd390 ebp 0xffffd3c8 0xffffd3c8 esi 0x0 0 edi 0x0 0 eip 0x8048b60 0x8048b60 <main+16> eflags 0x286 [ PF SF IF ] cs 0x23 35 ss 0x2b 43 ds 0x2b 43 es 0x2b 43 fs 0x0 0 gs 0x63 99 After this patch, these commands print the third column values consistently aligned one under another, provided the second column is not too long. Originally, the third column was (attempted to be) aligned using a simple tab character. This patch changes the alignment to spaces only. The tests checking the output and expecting the single tab have been fixed in a previous patch, so this change doesn't break any. gdb/ChangeLog: * infcmd.c (default_print_one_register_info): Align natural-format column values consistently one under another. (pad_to_column): New function.

2018-02-02MI: Allow non-raw varobj evaluationLeszek Swirski via gdb-patches7-2/+70
Make the MI variable object expression evaluation, with the -var-evaluate-expression command, recursively call pretty printers, to match the output of normal expression printing. Consider the following code: struct Foo { int val; }; struct Wrapper { Foo foo; }; int main() { Wrapper w; w.foo.val = 23; } and this pretty printer file: import gdb.printing class FooPrinter: def __init__(self, val): self.val = val def to_string(self): return "Foo" + str(self.val["val"]) class WrapperPrinter: def __init__(self, val): self.val = val def to_string(self): return self.val["foo"] test_printer = gdb.printing.RegexpCollectionPrettyPrinter("test") test_printer.add_printer('Foo', '^Foo$', FooPrinter) test_printer.add_printer('Wrapper', '^Wrapper$', WrapperPrinter) gdb.printing.register_pretty_printer(None, test_printer) Setting a breakpoint at the end of the function, we call the following commands: -enable-pretty-printing ^done -var-create var_w @ w ^done,name="var_w",numchild="0",value="{val = 23}",type="Wrapper",dynamic="1",has_more="0" -var-create var_w_foo @ w.foo ^done,name="var_w_foo",numchild="0",value="Foo23",type="Foo",dynamic="1",has_more="0" -var-evaluate-expression var_w ^done,value="{val = 23}" -var-evaluate-expression var_w_foo ^done,value="Foo23" -data-evaluate-expression w ^done,value="Foo23" -data-evaluate-expression w.foo ^done,value="Foo23" So, in the -var-evaluate-expression var_w case, we print the "raw" value of w.foo, while in the -data-evaluate-expression w case, we print the pretty printed w.foo value. After this patch, all of the above print "Foo23". gdb/ChangeLog: * varobj.c (varobj_formatted_print_options): Allow recursive pretty printing if pretty printing is enabled. gdb/testsuite/ChangeLog: * gdb.python/py-prettyprint.c (struct to_string_returns_value_inner, struct to_string_returns_value_wrapper): New.
