relocs_compatible test for gc-sections
I noticed when looking at pr22300 that before calling check_relocs we
have an elf_object_id test (added for pr11933) as well as the
relocs_compatible test. I believe backend gc_mark_hook and
gc_sweep_hook ought to be protected similarly from being confused by
unexpected relocations (for example, both elf64-ppc.c and elf32-ppc.c
use _bfd_elf_relocs_compatible, so I think it would be possible for
the ppc64 gc_mark_hook to be presented with a ppc32 relocatable
object).

C++ify xml-syscall.c
This patch C++ifies the structures in xml-syscall.c, by using
std::vector instead of VEC, and std::string instead of char*.
Using a unique_ptr in syscall_parse_xml allows to remove a cleanup.
Something that seems strange with the existing code, if you look at
syscalls_info_free_syscalls_desc and
syscalls_info_free_syscall_group_desc, they free the structure elements
(the strings and vectors), but they don't free the syscall_desc and
syscall_group_desc structure themselves. I don't see anything freeing
those currently. Any idea why? According to the comment above
syscalls_info_free_syscall_group_desc, it kinda looks like it's on
purpose. With this patch, those structures are deleted when the vector
that contains them gets deleted.
The only time I'm aware a syscalls_info structure gets deleted is in the
case the data directory changes during runtime, in init_syscalls_info.
If tried that use case (including under valgrind):
(gdb) catch syscall
(gdb) set data-directory another-data-directory
(gdb) catch syscall
I confirmed that the syscalls_info structure got deleted and recreated,

Fix broken recursion detection when printing static members
Recursion detection for static members was broken. The implementation
uses a growing (and shrinking) obstack object to simulate a stack of
addresses (CORE_ADDR). Pushing addresses is implemented by calling
obstack_grow(), while popping is implemented by calling obstack_free().
The latter is problematic because obstack_free() expects a pointer to
the base of an object. When popping elements of the stack however,
obstack_free() was called with the new top, which potentially is not the
same as the base of the stack. This is unintended use and the effect is
that obstack->next_free and obstack->object_base members are assigned
the value of the new top, which equals an empty stack. Summary: popping
elements would always result in an empty stack, which breaks the
recursion detection.
The fix shrinks the stack using obstack_blank_fast() with a negative
value as described at the bottom of this page:
https://gcc.gnu.org/onlinedocs/libiberty/Extra-Fast-Growing.html "You
can use obstack_blank_fast with a “negative” size argument to make the
current object smaller. Just don’t try to shrink it beyond zero
length—there’s no telling what will happen if you do that. Earlier
versions of obstacks allowed you to use obstack_blank to shrink objects.
This will no longer work."
The reproducer is added to gdb.cp/classes.exp, which fails without this
patch.

This patches removes get_regcache_arch, and use regache->arch () instead.
The motivation of this change is that I am going to move some basic stuff
into a base class of regcache. I don't need to update "client" code
regcache->arch (). On the other hand, this patch shortens the code a
little bit.

Target FP: Use target format throughout expression parsing
When parsing floating-point literals, the language parsers currently
use parse_float or some equivalent routine to parse the input string
into a DOUBLEST, which is then stored within a OP_DOUBLE expression
node. When evaluating the expression, the OP_DOUBLE is finally
converted into a value in target format.
On the other hand, *decimal* floating-point literals are parsed
directly into target format and stored that way in a OP_DECFLOAT
expression node. In order to eliminate the DOUBLEST, this patch
therefore unifies the handling of binary and decimal floating-
point literals and stores them both in target format within a
new OP_FLOAT expression node, replacing both OP_DOUBLE and
OP_DECFLOAT.
In order to store literals in target format, the parse_float
routine needs to know the type of the literal. All parsers
therefore need to be changed to determine the appropriate type
(e.g. by detecting suffixes) *before* calling parse_float,
instead of after it as today. However, this change is mostly
straightforward -- again, this is already done for decimal FP
today.
The core of the literal parsing is moved into a new routine
floatformat_from_string, mirroring floatformat_to_string.
The parse_float routine now calls either floatformat_from_string
or decimal_from_sting, allowing it to handle any type of FP
literal.
All language parsers need to be updated. Some notes on
specific changes to the various languages:
- C: Decimal FP is now handled in parse_float, and no longer
needs to be handled specially.
- D: Straightforward.
- Fortran: Still used a hard-coded "atof", also replaced by
parse_float now. Continues to always use builtin_real_s8
as the type of literal, even though this is probably wrong.
- Go: This used to handle "f" and "l" suffixes, even though
the Go language actually doesn't support those. I kept this
support for now -- maybe revisit later. Note the the GDB
test suite for some reason actually *verifies* that GDB supports
those unsupported suffixes ...
- Pascal: Likewise -- this handles suffixes that are not
supported in the language standard.
- Modula-2: Like Fortran, used to use "atof".
- Rust: Mostly straightforward, except for a unit-testing hitch.
The code use to set a special "unit_testing" flag which would
cause "rust_type" to always return NULL. This makes it not
possible to encode a literal into target format (which type?).
The reason for this flag appears to have been that during
unit testing, there is no "rust_parser" context set up, which
means no "gdbarch" is available to use its types. To fix this,
I removed the unit_testing flag, and instead simply just set up
a dummy rust_parser context during unit testing.
- Ada: This used to check sizeof (DOUBLEST) to determine which
type to use for floating-point literal. This seems questionable
to begin with (since DOUBLEST is quite unrelated to target formats),
and in any case we need to get rid of DOUBLEST. I'm now simply
always using the largest type (builtin_long_double).

Target FP printing: Simplify and fix ui_printf
This patch adds support for handling format strings to both
floatformat_to_string and decimal_to_string, and then uses
those routines to implement ui_printf formatted printing.
There is already a subroutine printf_decfloat that ui_printf uses to
handle decimal FP. This is renamed to printf_floating and updated
to handle both binary and decimal FP. This includes the following
set of changes:
- printf_decfloat currently parses the format string again to determine
the intended target format. This seems superfluous since the common
parsing code in parse_format_string already did this, but then did
not pass the result on to its users. Fixed by splitting the decfloat_arg
argument class into three distinct classes, and passing them through.
- Now we can rename printf_decfloat to printf_floating and also call it
for the argument classes representing binary FP types.
- The code will now use the argclass to detect the type the value should
be printed at, and converts the input value to this type if necessary.
To remain compatible with current behavior, for binary FP the code
instead tries to re-interpret the input value as a FP type of the
same size if that exists. (Maybe this behavior is more confusing
than useful -- but this can be changed later if we want to ...)
- Finally, we can use floatformat_to_string / decimal_to_string passing
the format string to perform the formatted output using the desired
target FP type.
Note that we no longer generate different code depending on whether or not
the host supports "long double" -- this check is obsolete anyway since C++11
mandates "long double", and in any case a %lg format string is intended to
refer to the *target* long double type, not the host version.
Note also that formatted printing of DFP numbers may not work correctly,
since it attempts to use the host printf to do so (and makes unwarranted
assumptions about the host ABI while doing so!). This is no change to
the current behavior -- I simply moved the code from printf_decfloat to
the decimal_to_string routine in dfp.c. If we want to fix it in the
future, that is a more appropriate place anyway.

2017-10-24 Ulrich Weigand <uweigand@de.ibm.com>

Target FP printing: Simplify and fix print_floating
The print_floating routine currently makes a lot of assumptions about host
and target floating point formats. This patch cleans up many of those.
One problem is that print_floating may currently be called with types
that are not actually floating-point types, and it tries hard to output
those as floating-point values anyway. However, there is only one single
caller of print_floating where this can ever happen: print_scalar_formatted.
And in fact, it is much simpler to handle the case where the value to be
printed is not already of floating-point type right there.
So this patch changes print_scalar_formatted to handle the 'f' format
as follows:
- If the value to be printed is already of floating-point type, just
call print_floating on it.
- Otherwise, if there is a standard target floating-point type of
the same size as the value, call print_floating using that type.
- Otherwise, just print the value as if the 'f' format had not been
specified at all.
This has the overall effect to printing everything the same way as
the old code did, but is overall a lot simpler. (Also, it would
allow us to change the above strategy more easily, if that might
be a more intuitive user interface. For example, in the third
case above, maybe an error would be more appropriate?)
Given that change, print_floating can become much simpler. In particular,
we now always have a floating-point format that we can consult. This
means we can use the floating-point format to programmatically determine
the number of digits necessary to print the value.
The current code uses a hard-coded value of 9, 17, or 35 digits. Note
that this matches the DECIMAL_DIG values for IEEE-32, IEEE-64, and
IEEE-128. (Actually, for IEEE-128 the correct value is 36 -- the 35
seems to be an oversight.) The DECIMAL_DIG value is defined to be
the smallest number so that any number in the target format, when
printed to this number of digits and then scanned back into a binary
floating-point number, will result in the original value.
Now that we always have a FP format, we can just compute the DECIMAL_DIG
value using the formula from the C standard. This will be correct for
*all* FP formats, not just the above list, and it will be correct (as
opposed to current code) if the target formats differ from the host ones.
The patch moves the new logic to a new floatformat_to_string routine
(analogous to the existing decimal_to_string). The print_floating
routine now calls floatformat_to_string or decimal_to_string, making
the separate print_decimal_floating and generic_val_print_decfloat routines
unnecessary.

Drop /proc/PID/status polling from gdb.threads/attach-into-signal.exp
I noticed that the 'with_test_prefix "stoppedtry $stoppedtry"' prefix
in this testcase is unnecessary, because inside that block there are
no pass/fail calls. In fact the block includes a comment saying:
# No PASS message as we may be looping in multiple
# attempts.
but looking deeper at this I noticed a few odd things with this code
block:
1. This code is assuming that the second line in the /proc/PID/status
files is the "State:" line, which may have been true when this was
originally written, but is not true on my machine at least (Linux
4.8.13).
$ cat /proc/self/status
Name: cat
Umask: 0002
State: R (running)
So nowadays, that 'string match "*(stopped)*"' is running against
the "Umask:" line and thus always returns false, meaning the loop
always breaks on $stoppedtry == 0.
2. The loop seems to be waiting for the process to become "(stopped)",
but if so then that 'if {![string match]}' check is reversed, it
should be checking 'if {[string match]}' instead, because "string
match" returns true if the string matches, not 0.
3. But if we fixed all that, we'd still run into the simple fact that
nothing is actually stopping the test's inferior process before GDB
attaches... The top of the testcase says:
# This test was created by modifying attach-stopped.exp.
... and attach-stopped.exp does have:
# Stop the program
remote_exec build "kill -s STOP ${testpid}"
but then attach-stopped.exp doesn't have an equivalent
/proc/PID/status poll loop... (Maybe it could.)
So remove this whole loop as useless.

Fix unstable test names in gdb.base/startup-with-shell.exp
Currently, if you diff testsuite/gdb.sum of two builds in different

Since the run_args arguments are already shown in the test prefix, we
can change the "set args" test name to literally "set args $run_args".
I.e., after this commit we'll show:
PASS: gdb.base/startup-with-shell.exp: startup_with_shell = on; run_args = *.unique-extension: set args $run_args
PASS: gdb.base/startup-with-shell.exp: startup_with_shell = off; run_args = *.unique-extension: set args $run_args

RISC-V: Don't emit 2-byte NOPs if the C extension is disabled
Systems without the C extension mandate 4-byte alignment for
instructions, so there is no reason to allow for 2-byte alignment. This
change avoids emitting lots of unimplemented instructions into object
files on non-C targets, which users keep reporting as a bug. While this
isn't actually a bug (as none of the offsets in object files are
relevant until RISC-V), it is ugly.

MIPS: Preset EF_MIPS_ABI2 with n32 ELF objects
Fix a bug in MIPS n32 ELF object file generation and make such objects
consistent with the n32 BFD requested, by presetting the EF_MIPS_ABI2
flag in the `e_flags' member of the newly created ELF file header, as it
is this flag that tells n32 objects apart from o32 objects.
This flag will then stay set through to output file generation for
writers such as GAS or GDB's `generate-core-file' command. Readers will
overwrite the whole of `e_flags' along with the rest of the ELF file
header in `elf_swap_ehdr_in' and then verify in `mips_elf_n32_object_p'
that the flag is still set before accepting an input file as an n32
object.
The issue was discovered with GDB's `generate-core-file' command making
o32 core files out of n32 debuggees.

Get rid of VEC (mem_region)
This patch removes VEC (mem_region). Doing so requires touching a lot
of little things here and there.
The fields in mem_attrib are now initialized during construction. The
values match those that were in default_mem_attrib (now removed).
unknown_mem_attrib is also removed, and replaced with a static method
(mem_attrib::unknown) that returns the equivalent.
mem_region is initialized in a way similar to mem_region_init (now
removed) did.
I found the organization of mem_region_list and target_mem_region_list a
bit confusing. Sometimes mem_region_list points to the same vector as
target_mem_region_list (and therefore does not own it), and sometimes
(when the user manually edits the mem regions) points to another vector,
and in this case owns it. To avoid this ambiguity, I think it is
simpler to have two vectors, one for target-defined regions and one for
user-defined regions, and have mem_region_list point to one or the
other. There are now no vector objects dynamically allocated, both are
static.
The make-target-delegates script does not generate valid code when a
target method returns a type with a parameter list. For this reason, I
created a typedef (mem_region_vector) that's only used in the target_ops
structure. If you speak perl, you are welcome to improve the script!

Create a displaced_step_closure class hierarchy
displaced_step_closure is a type defined in multiple -tdep.c files.
Trying to xfree it from the common code (infrun.c) is a problem when we
try to poison xfree for non-POD types. Because there can be multiple of
these types in the same build, this patch makes a hierarchy of classes
with a virtual destructor. When the common code deletes the object
through a displaced_step_closure pointer, it will invoke the right
destructor.
The amd64 used a last-member array with a variable size. That doesn't
work with new, so I changed it for an std::vector. Other architectures
which used a simple byte buffer as a closure now use a shared
buf_displaced_step_closure, a closure type that only contains a
