7 years agoFixing for PR gold/21491 - Errata workaround can produce broken images.
Han Shen [Mon, 10 Jul 2017 22:23:05 +0000 (15:23 -0700)] 
Fixing for PR gold/21491 - Errata workaround can produce broken images.

The problem is caused by the fact that gold is relocating the stubs
for an entire output section when it processes the relocations for a
particular input section that happened to be designated as the stub
table "owner". The Relocate_task for that input section may or may not
run before the Relocate_task for another input section that contains
the code that needs the erratum fix, but doesn't "own" the stub
table. If it runs before (or might even race with) that other task, it
ends up with a copy of the unrelocated original instruction.

In other words - when calling fix_errata() from
do_relocate_sections(), gold is going through the list of errata stubs
that are associated only with that object. This routine updates the
stored original instruction and replaces it in the output view with a
branch to the stub. Later, as gold is going through the object file's
input sections, it then checks for stub tables "owned" by each input
section, and writes out all the stubs from that stub table, regardless
of what object file each stub is associated with.

Fixed by relocating the erratum stub only after the corresponding
errata spot is fixed. That is to have fix_errata() call
Stub_table::relocate_erratum_stub() for each stub.

considered skipped by the "op_ptr += addr_size", but it is never read.
uoffset is indeed read just after, without having been assigned first.

Fix size check in dwarf2_evaluate_loc_desc_full

report had a different error) is that a pieced DWARF expression is not
writing to every byte in the resulting value.  GDB errors in this
case.  However, it seems to me that it is always valid to write fewer
bytes; the issue comes from writing too many -- that is, the test is
reversed.  The test was also checking the sub-object, but this also
seems incorrect, as it's expected for the expression to write the
entirety of the enclosing object.  So, this patch reverses the test
and applies it to the outer type, not the subobject type.

slots"), <https://sourceware.org/ml/binutils/2008-08/msg00096.html>,
regression and a more recent:

FAIL: ld-unique/pr21529

new LD test case failure, observed with all the relevant MIPS targets
whenever the linker is invoked with one or more ELF inputs and the
output format set to `binary'.

The culprit is a segmentation fault caused in `mips_before_allocation'
by a null pointer dereference, where an attempt is made to access the
ELF file header's `e_flags' member, for the purpose of determining
whether to produce a PLT and copy relocations, without first checking
that the output BFD is ELF.  The `e_flags' member is stored in BFD's
private data pointed to by `tdep', which in the case of the `binary' BFD
is null, causing the segmentation fault.  With other non-ELF BFDs such
as SREC `tdep' is not null and consequently no crash may happen and in
that case random data will be interpreted as it was `e_flags'.

Disable the access to `e_flags' then and all the associated checks and
consequently never produce a PLT and copy relocations if output is not a
MIPS ELF BFD, matching `_bfd_mips_elf_merge_private_bfd_data' that does
not process `e_flags' in that case either and therefore does not let us
decide here anyway if all the input objects included in the link are
suitable for use with a PLT and copy relocations.

Fission support for multiple CUs per DWO file

In some cases a compiler may produce a single object file (& thus single
DWO file) representing multiple source files. The most common example of
this is in whole program optimization (such as LLVM's LTO). Fission may
still be a beneficial feature to use here - to avoid the need to
read/link the debug info with system libraries and the like.

This change adds basic support for multiple CUs in a single DWO file to
support LLVM's output in this situation.

There is still outstanding work to design and implement a solution for
cross-CU references (usually using DW_FORM_ref_addr) in this scenario.
For now LLVM works around this by duplicating DIEs rather than making
cross-CU references in DWO files. This degrades debugger
behavior/quality especially for file-local entities.

PR cli/21688: Fix multi-line/inline command differentiation

This bug is a regression caused by the following commit:

  604c4576fdcfc4e7c28f569b3748a1b6b4e0dbd4 is the first bad commit
  commit 604c4576fdcfc4e7c28f569b3748a1b6b4e0dbd4
  Author: Jerome Guitton <guitton@adacore.com>
  Date:   Tue Jan 10 15:15:53 2017 +0100

The problem happens because, on cli/cli-script.c:process_next_line,
GDB is not using the command line string to identify which command to
run, but it instead using the 'struct cmd_list_element *' that is
obtained by using the mentioned string.  The problem with that is that
the 'struct cmd_list_element *' doesn't have any information on
whether the command issued by the user is a multi-line or inline one.

A multi-line command is a command that will necessarily be composed of
more than 1 line.  For example:

  (gdb) if 1
  >python
   >print ('hello')
   >end
  >end

As can be seen in the example above, the 'python' command actually
"opens" a new command line (represented by the change in the
indentation) that will then be used to enter Python code.  OTOH, an
inline command is a command that is "self-contained" in a single line,
for example:

  (gdb) if 1
  >python print ('hello')
  >end

This Python command is a one-liner, and therefore there is no other
Python code that can be entered for this same block.  There is also no
change in the indentation.

So, the fix is somewhat simple: we have to revert the change and use
the full command line string passed to process_next_line in order to
identify whether we're dealing with a multi-line or an inline command.
This commit does just that.  As can be seen, this regression also
affects other languages, like guile or the compile framework.  To make
things clearer, I decided to create a new helper function responsible
for identifying a non-inline command.

Testcase is attached.

MIPS: Fix XPA base and Virtualization ASE instruction handling

Correct a commit 7d64c587c15f ("Add support for the MIPS eXtended

ASE instructions to be wrongly always enabled with the selection of the
MIPS32r2 or higher ISA.

For example this source assembles successfully as shown below:

$ as -32 -mips32 -o xpa.o xpa.s

Disassembly of section .text:

To address this issue remove the I33 (INSN_ISA32R2) marking from all XPA
instructions in the opcode table.  Additionally, for XPA Virtualization
ASE instructions implement an XPAVZ (ASE_XPA_VIRT) combination ASE flag
and use it in place of IVIRT|XPA (ASE_VIRT|ASE_XPA).

Now the same source is correctly rejected unless the `-mxpa' option is
also used:

$ as -32 -mips32r2 -o xpa.o xpa.s
xpa.s: Assembler messages:

Pedro Alves [Thu, 29 Jun 2017 14:52:38 +0000 (15:52 +0100)] 
Expression completer should not match explicit location options

This commit fixes a mismatch between what "print" command completer
thinks the command understands, and what the command actually
understands.

The explicit location options are understood by commands that take
(linespecs and) explicit locations as argument.  I.e, breakpoint
commands, and "list".  For example:

 (gdb) b -source file.c -function my_func

So for those commands, it makes sense that the completer
completes:

 "b -sour[TAB]" -> "b -source "
 "b -functi[TAB]" -> "b -function "

etc.

However, completion for commands that take expressions (not
linespecs/locations) as arguments, such as the "print" command, also
completes the explicit location options, even though those switches
aren't really understood by these commands.  Instead, "-foo" is
understood as an expression applying unary minus on a symbol named
"foo" (think "print -1"):

 (gdb) p -func[TAB]
 (gdb) p -function [RET]
 No symbol "function" in current context.

The patch fixes this by having the expression_completer function
bypass the function that completes explicit locations.

New regression tests included.

[ARC] Fix handling of cpu=... disassembler option value

There is a bug in handling of cpu=... disassembler option in case there are
other options after it, for example, `cpu=EM,dsp'.  In this case `EM,dsp' is
treated as an option value, and strcasecmp reports is as non-equal to "EM".
This is fixed by using disassembler_options_cmp function, which compares string
treating `,' the same way as `\0'.

This function also solves a problem with option order in parse_option.
Previously, if several option had same prefix (e.g. fpud, fpuda), then the
longer one should have been compared first, otherwise when longer option is
passed it would be treated as a short one, because

  CONST_STRNEQ ("fpud", "fpuda")

would be true.  The order of options was correct for ARC, so there were no
bugs per se, but with disassembler_option_cmp there is no risk of such a bug
being introduced in the future.
