Unavailable data is handled gracefully in MIPS GOT processing done by
`print_mips_got_entry', so all that is needed in special GOT[1] handling
is to verify whether data can be retrieved for the purpose of the GNU
marker check done with `byte_get'. Remove the extra error reporting
code then, introduced with commit 75ec1fdbb797 ("Fix runtime seg-fault
in readelf when parsing a corrupt MIPS binary.") in the course of
addressing PR binutils/21344, and defer the error case to regular local
GOT entry processing.

Null data is handled gracefully throughout in MIPS GOT processing, with
addresses printed normally and unavailable data shown as `<unknown>' by
`print_mips_got_entry', and special processing code for GOT[1] doing an
explicit check. Remove an unwanted null GOT data check then, introduced
with commit 592458412fb2 in the course of addressing PR binutils/12855.

struct btrace_insn is not a POD [1] so we shouldn't be using memset to
initialize it [2].
Use list-initialization instead, wrapped in a "pt insn to btrace insn"
function, which looks like just begging to be added next to the
existing pt_reclassify_insn/pt_btrace_insn_flags functions.
[1] - because its field "flags" is not POD, because enum_flags has a

So, VECs (given it's C roots) rely on memcpy/memcpy of VEC elements to
be well defined, in order to grow/reallocate its internal elements
array. This means that we can only put trivially copyable types in
VECs. E.g., if a type requires using a custom copy/move ctor to
relocate, then we can't put it in a VEC (so we use std::vector
instead). But, as shown above, we're violating that requirement.
btrace_insn is currently not trivially copyable, because it contains
an enum_flags field, and that is itself not trivially copyable. This
patch corrects that, by simply removing the user-provided copy
constructor and assignment operator. The compiler-generated versions
work just fine.
Note that std::vector relies on std::is_trivially_copyable too to know
whether it can reallocate its elements with memcpy/memmove instead of
having to call copy/move ctors and dtors, so if we have types in
std::vectors that weren't trivially copyable because of enum_flags,
this will make such vectors more efficient.

The LDR rX, =cst pseudo-instruction suffers from two issues for loading
integer constants in Thumb mode:
- movs is used if the constant and register can be encoded using that
instruction which leads to unexpected behavior due to its flag-setting
behavior
- mov.w, movw and mvn are used for r13 (sp) and r15 (pc) but these
encoding are marked as UNPREDICTABLE
This patch fixes those issues and update testing accordingly.

I noticed that the documentation on how the info about threads is output
in MI is duplicated and not up to date. The duplication is between the
"GDB/MI Thread Information" page and the -thread-info result
description.
I improved the "GDB/MI Thread Information" page a bit and referred to it
in the -thread-info doc. This way, the -thread-info doc is more precise
(it did not mention the "threads" and "current-thread-id" attributes)
and concise.
gdb/doc/ChangeLog:
* gdb.texinfo (GDB/MI Thread Information): Add missing
fields, re-word some things.
(GDB/MI Thread Commands): Describe fields found in the output of
-thread-info, remove description of fields in the
thread output tuple, replace with a cross-reference to "GDB/MI
Thread Information".
|
|
The MI documentation says that -thread-info output contains a "current"
field in the current thread tuple, with the value "*". Current GDB
master does not do this, and I couldn't find any GDB version that did.
I suspect that it was never the case.
The code that would correspond to this in print_thread_info_1 is
essentially dead code. The calls to uiout->text end up in
mi_out::do_text, which is empty.
This patch removes the documentation bit and the dead code. This
"current" field is not necessary, since -thread-info outputs a
"current-thread-id" field.
gdb/ChangeLog:
* thread.c (print_thread_info_1): Remove dead code.
gdb/doc/ChangeLog:
* gdb.texinfo (GDB/MI Thread Commands): Remove "current" field
from -thread-info output.

GOT reference to global symbol in PIE will lead to dynamic symbol. It
becomes a problem when "time" or "times" is defined as a variable in
an executable, clashing with functions of the same name in libc. If
a symbol isn't undefined weak symbol, don't make it dynamic in PIE and
generate R_386_RELATIVE relocation.

When -static -E/--dynamic-list are passed to linker, linker may create
executable with dynamic sections which aren't supported by run-time.
We require --no-dynamic-linker together with -static -E/--dynamic-list

This patches removes the 2nd argument of regcache_restore, because it
is only called by regcache_cpy. In regcache_cpy, if regcache_restore
is called, dst is not readonly, but src is readonly. So this patch
adds an assert that src is readonly in regcache_restore.
regcache_cook_read read everything from a readonly regcache cache
(src)'s register_buffer, and register status is from ->register_status.

argument 3 with regcache. Get register status from
