No longer create readonly regcache
Nowadays, we create a readonly regcache in get_return_value, and pass it
to gdbarch_return_value to get the return value. In theory, we can pass a
readable_regcache instance and get the return value, because we don't need
to modify the regcache. Unfortunately, gdbarch_return_value is designed
to multiplex regcache, according to READBUF and WRITEBUF.
# If READBUF is not NULL, extract the return value and save it in this
# buffer.
#
# If WRITEBUF is not NULL, it contains a return value which will be
# stored into the appropriate register.
In fact, gdbarch_return_value should be split to three functions, 1) only
return return_value_convention, 2) pass regcache_readonly and readbuf, 3)
pass regcache and writebuf. These changes are out of the scope of this
patch series, so I pass regcache to gdbarch_return_value even for read,
and trust each gdbarch backend doesn't modify regcache.

reg_buffer (because some dump modes like regcache_dump_none,

Class detached_regcache
jit.c uses the regcache in a slightly different way, the regcache dosen't
write through to target, but it has read and write methods. If I apply
regcache in record-full.c, it has the similar use pattern. This patch
adds a new class detached_regcache, a register buffer, but can be
read and written.
Since jit.c doesn't want to write registers through to target, it uses
regcache as a readonly regcache (because only readonly regcache
disconnects from the target), but it adds a hole in regcache
(raw_set_cached_value) in order to modify a readonly regcache. This patch
fixes this hole completely.
regcache inherits detached_regcache, and detached_regcache inherits
readable_regcache. The ideal design is that both detached_regcache and
readable_regcache inherit reg_buffer, and regcache inherit
detached_regcache and regcache_read (virtual inheritance). I concern
about the performance overhead of virtual inheritance, so I don't do it in
the patch.

class readable_regcache and pass readable_regcache to gdbarch pseudo_register_read and pseudo_register_read_value
pseudo registers are either from raw registers or memory, so
gdbarch methods pseudo_register_read and pseudo_register_read_value
should have regcache object which only have read methods. In other
words, we should disallow writing to regcache in these two gdbarch
methods. In order to apply this restriction, this patch adds a new
class readable_regcache, derived from reg_buffer, and it only has
raw_read and cooked_read methods. regcache is derived from
readable_regcache. This patch also passes readable_regcache instead of
regcache to gdbarch methods pseudo_register_read and
pseudo_register_read_value.
This patch moves raw_read* and cooked_read* methods to readable_regcache,
which is straightforward. One thing not straightforward is that I split
regcache::xfer_part to readable_regcache::read_part and regcache::write_part,
because readable_regcache can only have methods to read.
readable_regcache is an abstract base class, and it has a pure virtual
function raw_update, because I don't want readable_regcache know where
these raw registers are from. They can be from either the target
(readwrite regcache) or the regcache itself (readonly regcache).

btrace, testsuite: do not force BTS
In gdb.btrace/buffer-size.exp we explicitly ask for the BTS recording format.
This may lead to spurious fails on systems where PT is being used by some other

MIPS/BFD: Fix the size of `.reginfo' and `.MIPS.abiflags' sections
Use the SEC_FIXED_SIZE flag to actually fix the size of `.reginfo' and
`.MIPS.abiflags' sections in `_bfd_mips_elf_always_size_sections', as
originally intended, removing link failures such as:
ld: final link failed: Section has no contents
or:
ld: final link failed: Bad value
or:
ld: foo: .reginfo section size should be 24 bytes, actual size is 32
and assertion failures like:
ld: BFD (GNU Binutils) 2.30.51.
20180131 assertion fail .../bfd/elfxx-mips.c:14322
in link scenarios involving a linker script that either creates an
output `.reginfo' or `.MIPS.abiflags' section from scratch or produces
either section from different sections. If such an output section's
size turns out to be incorrect according to the psABI, then the section
is either truncated or padded out to the correct size, as relevant.
This allows people to handle these sections in a link in an unusual way,
while still addressing the issue covered by commit
58807c48a5a3
("_bfd_mips_elf_final_link: Notify user about wrong .reginfo size").
The original arrangement, coming from an unindentified change made to
what was called `mips_elf_always_size_sections' back then, between
commit
02650bd0a97e ("This adds ABI flags to MIPS/ELF object files.")
and commit
252b5132c753 ("
19990502 sourceware import"), also missing
from BFD ChangeLog files, assumed that the output section size is not
going to change after return from `bfd_elf_size_dynamic_sections', the
caller of that function, called in turn from `ldemul_before_allocation'
via `gld${EMULATION_NAME}_before_allocation' in ld/emultempl/elf32.em,
and ultimately from `lang_process'. This is because later on in
`lang_process' processing `lang_size_sections' is called , happily
recalculating the section size, and it has actually already been the
case at the time of commit
252b5132c753 ("
19990502 sourceware import"),
so the assumption was clearly incorrect right from the beginning.

Add .nop assembler directive
Implement the '.nop SIZE[, CONTROL]' assembler directive, which emits
SIZE bytes filled with no-op instructions. SIZE is absolute expression.
The optional CONTROL byte controls how no-op instructions should be
generated. If the comma and @var{control} are omitted, CONTROL is
assumed to be zero.
For Intel 80386 and AMD x86-64 targets, CONTROL byte specifies the size
limit of a single no-op instruction. The valid values of CONTROL byte
are between 0 and 8 for 16-bit mode, between 0 and 10 for 32-bit mode,
between 0 and 11 for 64-bit mode. When 0 is used, the no-op size limit
is set to the maximum supported size.
2 new relax states, rs_space_nop and rs_fill_nop, are added to enum
_relax_state, which are similar to rs_space and rs_fill, respectively,
but they fill with no-op instructions, instead of a single byte. A
target backend must override the default md_generate_nops to generate
proper no-op instructions. Otherwise, an error of unimplemented .nop
directive will be issued whenever .nop directive is used.

because, if the symbol is created at this point, the link will abort
later in elf_link_output_extsym. This changes the TRUE into a FALSE

Fix GDB crash after Quit thrown from unwinder sniffer
I ran into a GDB crash in gdb.base/bp-cmds-continue-ctrl-c.exp in my
multi-target branch, which turns out exposed a bug that exists in
master too.
That testcase has a breakpoint with a "continue" command associated.
Then the breakpoint is constantly being hit. At the same time, the
testcase is continualy interrupting the program with Ctrl-C, and
re-resuming it, in a loop.
Running that testcase manually under Valgrind, after a few sequences
of 'Ctrl-C' + 'continue', I got:

Above, when we get to compute_frame_id, fi->unwind is non-NULL,
meaning, we found an unwinder, in this case the Python unwinder, but
somehow, fi->prologue_cache is left NULL. pyuw_this_id then crashes
because it assumes fi->prologue_cache is non-NULL:
static void
pyuw_this_id (struct frame_info *this_frame, void **cache_ptr,
struct frame_id *this_id)
{
*this_id = ((cached_frame_info *) *cache_ptr)->frame_id;
^^^^^^^^^^
'*cache_ptr' here is 'fi->prologue_cache'.
There's a quit() call in pyuw_sniffer that I believe is the one that
sometimes triggers the crash above. The crash can be reproduced
easily with this hack to force a quit out of the python unwinder:
--- a/gdb/python/py-unwind.c

After that quit is thrown, any subsequent operation that involves

Fix compilation of the BFD sub-directory with a gcc v8 compiler by adding extra casts.
GCC v8 issues warnings about mis-matching casts of function pointers.

which accepted a variable number of arguments. But this introduces serious
problems when compiled with other versions of gcc, (notably gcc 4.4). This

function types without a parameter list).

x86-64: Use PLT address for PC-relative reloc
Since PLT in PDE and PC-relative PLT in PIE can be used as function
address, there is no need for dynamic PC-relative relocation against
a dynamic function definition in PIE. Linker should resolve PC-relative
reference to its PLT address.
NB: i386 has non-PIC PLT and PIC PLT. Only non-PIC PLT in PDE can
be used as function address. PIC PLT in PIE can't be used as

Since there is no need to prepare for PLT branch on x86-64, generate

From: "H.J. Lu" <hjl.tools@gmail.com>
Subject: [PATCH] x86: Treat R_X86_64_PLT32 as R_X86_64_PC32
On i386, there are 2 types of PLTs, PIC and non-PIC. PIE and shared
objects must use PIC PLT. To use PIC PLT, you need to load
_GLOBAL_OFFSET_TABLE_ into EBX first. There is no need for that on
x86-64 since x86-64 uses PC-relative PLT.
On x86-64, for 32-bit PC-relative branches, we can generate PLT32
relocation, instead of PC32 relocation, which can also be used as
a marker for 32-bit PC-relative branches. Linker can always reduce
PLT32 relocation to PC32 if function is defined locally. Local
functions should use PC32 relocation. As far as Linux kernel is
concerned, R_X86_64_PLT32 can be treated the same as R_X86_64_PC32
since Linux kernel doesn't use PLT.

Fix prefix of maint set/show per-command
I noticed this:
(gdb) apropos per-command
maintenance set per-command -- Per-command statistics settings
set per-command space -- Set whether to display per-command space usage
set per-command symtab -- Set whether to display per-command symtab statistics
set per-command time -- Set whether to display per-command execution time
maintenance show per-command -- Show per-command statistics settings
show per-command space -- Show whether to display per-command space usage
show per-command symtab -- Show whether to display per-command symtab statistics
show per-command time -- Show whether to display per-command execution time
The subcommands of "maintenance set per-command" are missing the
maintenance keyword. This is because that command is registered with
the wrong prefix. This patch fixes that.
gdb/ChangeLog:
* maint.c (_initialize_maint_cmds): Fix prefix of maint set/show
per-command.
