4 years agoChange section_offsets to a std::vector
Tom Tromey [Mon, 6 Jan 2020 21:34:52 +0000 (14:34 -0700)]
Change section_offsets to a std::vector

This changes section_offsets to be specialization of a std::vector and
updates all the users.  It also removes the ANOFFSET and
SIZEOF_N_SECTION_OFFSETS macros.

Most of this is just a generic sort of cleanup, that reduces the
number of lines of code.  However, a couple spots were doing weird
things.

objfile_relocate did:

-      std::vector<struct section_offsets>
- new_debug_offsets (SIZEOF_N_SECTION_OFFSETS (debug_objfile->num_sections));

... which seems to greatly over-estimate the number of elements
needed.

This appeared in set_objfile_default_section_offset:

-  std::vector<struct section_offsets> offsets (objf->num_sections,
-        { { offset } });

... which makes sense due to type safety, but is also actively
confusing given that section_offsets was previously also a kind of
vector type.

Tested on x86-64 Fedora 30.

GDB: Fix the overflow in addr/line_is_displayed()

In tui_disasm_window::addr_is_displayed(), there can be situations
where "content" is empty. For instance, it can happen when the
"content" was not filled in tui_disasm_window::set_contents(),
because tui_disassemble() threw an exception. Usually this exception
is the result of fetching invalid PC addresses like the ones beyond
the end of the program.

Having "content.size ()" zero leads to an overflow in this condition
check inside tui_disasm_window::addr_is_displayed():

  int i = 0;
  while (i < content.size () - threshold ...) {
    ... content[i] ...
  }

"threshold" is 2 and there are times that "content.size ()" is 0.
This results into an overflow and the loop is entered whereas it
should have been skipped. Finally, "content[i]" access leads to
a segmentation fault.

Same problem applies to tui_source_window::line_is_displayed().

The issue has been discussed at length in bug 25345:
  https://sourceware.org/bugzilla/show_bug.cgi?id=25345

This commit avoids the segmentation faults with an early check:

  if (content.size () < SCROLL_THRESHOLD)
    return false;

Moreover, those functions have been overhauled to a leaner code.

AArch64: Set the correct ELF class for AArch64 stubs (PR/25210)

After doing this the stub section starts behaving like a normal object file
loaded from disk.  That is SEC_LINKER_CREATED causes us to have to write the
section manually.

This flag was added as a fix for PR 24753.  I believe that
fix to still be correct as linker created sections don't have a size on disk
and it fixes the Arm bootstrap regression. But in this case specifying the
correct section class also makes the stub section not be considered by
compress.c.

manually as implied by SEC_LINKER_CREATED.

Fix setting breakpoints or stepping on line 65535

This removes code that was present from the very first git revisison
7b4ac7e1ed2c4616bce56d1760807798be87ac9e from 1988.  It was in the
gdb/dbxread.c at the time (and makes more sense for dbx line info format
since line numbers are 16-bit entities in that debug format and debugging
files with more than 65535 lines would not work anyway) but moved from
there to gdb/buildsym.c which is used for dwarf line info as well, and
excluding an arbitrary line number does certainly not make sense nowadays.

Add a test case for line 65535
