Flash memory size not aligned to address
(This patch is from Mark Rages <markrages@gmail.com>.)
The Nordic nRF52 memory map, reported from black magic probe:
Num Enb Low Addr High Addr Attrs
0 y 0x00000000 0x00080000 flash blocksize 0x1000 nocache
1 y 0x10001000 0x10001210 flash blocksize 0x210 nocache
2 y 0x20000000 0x20010000 rw nocache
The region at 0x10001000 is "UICR" and it is a section of flash that is
erased all at once.
Notice the odd size: 0x210 is the size of the region defined in the
datasheet.
But because the block size was listed as 0x210, gdb was insisting on
issuing two erase commands divisible by 0x210, starting below 0x10001000.
This patch fixes it by doing the alignment computation from the start of
the region, not from address 0.

Eliminate catch_errors
If you want to use catch_errors with a function with parameters, then
currently you have to manually write a "capture" struct wrapping the
arguments and marshall/unmarshall that.
https://sourceware.org/ml/gdb-patches/2017-09/msg00834.html proposed
adjusting catch_errors to use gdb::function_view, which would allow
passing lambdas with automatic captures. However, it seems like using
TRY/CATCH directly instead ends up producing clearer and easier to
debug code. This is what this commit does.
Note that removing catch_errors exposes further cleanup opportunities
around no longer having to follow catch_errors callback type, and also
removes a few cleanups.
I didn't do anything to save/restore current_uiout because I think
that should be the responsibility of the code that changes
current_uiout in the first place.
(Another approach could be to make catch_errors a variadic template
like:
template<typename Function, typename... Args>
int catch_errors (const char *errstring, return_mask mask,
Function &&func, Args... args);
and then with:
extern void function_with_args (int, int);
extern void function_with_no_args ();
calls to the above functions would be wrapped like this:
catch_errors ("some error happened", RETURN_MASK_ERROR,
function_with_args, arg1, arg2);
catch_errors ("some error happened", RETURN_MASK_ERROR,
function_with_no_args);
but I'm thinking that that doesn't improve much if at all either.)

Multi-arch exec, more register reading avoidance
As mentioned in commit
bf93d7ba9931 ("Add thread after updating

process does an exec and before we've updated that inferior's gdbarch.
Otherwise, we may interpret the registers using the wrong
architecture.
There's still (at least) one case where we still read registers
post-exec with the pre-exec architecture. That's when infrun decides
it needs to switch context to the exec'ing thread. I.e., if the exec
event is processed at a time when the current thread is not already
the exec'ing thread, then we get (with the test added by this commit):

from a 64-bit mips architecture where bits_per_word is 64. As a
result, $_siginfo was not properly extracted from FreeBSD/mipsn32 core

Don't try building gdb against guile-2.2
GDB currently doesn't build with Guile 2.2 (see PR 21104). If one has
both Guile 2.2 and 2.0 installed, GDB will pick up Guile 2.2 first and
fail building. Until somebody does the work of adapting the GDB code to

Fix automatic dependency tracking
Commit
f38307f5 changed COMPILE.post and POSTCOMPILE to remove
$(basename) from the dependency file name computation. However, it
did not update the `-include' at the end of the Makefile.in; this in
effect disabled automatic dependency tracking.
This patch restores the $(basename) wrapper so that the dependency
files are named "file.Po" rather than "file.o.Po".
I also tested the non-gcc3 dependency mode, which pointed out that
this case hadn't been working since the switch to C++. This is also
fixed in this patch.

Fix a typo introduced in commit
c56e7c4390ed ("Make ctxobj.exp and

This doesn't really affect the outcome of the testcase. I only
noticed the typo because I stepped through the program manually.
To avoid such problems if the test is extended, this moves the STOP
marker until after the program self-validates the values. With the
typo in place, this alone would have resulted in a test FAIL. I.e.,

[RFC] Replicate src dir in build dir
Nowadays, GDB build tree is almost flat, but source tree isn't. We
have arch/ nat/ target/ common/ cli/ mi/ tui/ python/ guile/ directories.
We need to some rules in Makefile for source files in different source
directories, like,
# Rules for compiling .c files in the various source subdirectories.
%.o: ${srcdir}/arch/%.c
$(COMPILE) $<
$(POSTCOMPILE)
%.o: ${srcdir}/nat/%.c
$(COMPILE) $<
$(POSTCOMPILE)
so we should take care of some special case that files' base name is the
same, like,
# Specify an explicit rule for gdb/common/agent.c, to avoid a clash with the
# object file generate by gdb/agent.c.
common-agent.o: $(srcdir)/common/agent.c
$(COMPILE) $(srcdir)/common/agent.c
$(POSTCOMPILE)
As we add more and more files in different directories, it becomes tricky
to name files, because we need take this into account.
This patch takes the first step toward "Replicate src dir in build dir",
that is, we create arch/ directory in buildtree, and put amd64.o there
as an example. Dependency tracking is updated for files with directory
name. Currently, when we build amd64.o,
"-c -o amd64.o -MT amd64.o -MMD -MP -MF .deps/amd64.Tpo"
with this patch applied, it becomes,
"-c -o arch/amd64.o -MT arch/amd64.o -MMD -MP -MF arch/.deps/amd64.o.Tpo"
"make clean" removes the object files, and "make distclean" removes .deps
additionally. configure file create .deps directory in each of
CONFIG_SRC_SUBDIR, and pass it to Makefile.in, so that "make clean" and
"make distclean" can remove stuffs there.
If people agree with this change, I'll add more directories to
CONFIG_SRC_SUBDIR.

Clean up some DFP interfaces
This cleans up a number of interfaces in dfp.c / dfp.h. Specifically:
- The decimal_from_string / decimal_to_string routines are C++-ified
to operate on std::string instead of character buffers. In the
decimal_from_string, the boolean return value now actually is bool
instead of an int.
- The decimal_from_integral and decimal_from_doublest routines take
an struct value as input. This is not really appropriate at the low
level the DFP routines sit, so this replaced them with new routines
decimal_from_longest / decimal_from_ulongest / decimal_from_doublest
that operate on contents instead.
- To mirror the decimal_from_[u]longest, a new decimal_to_longest
routine is added as well, which can be used in unpack_long to
avoid an unnecessary conversion via DOUBLEST.
Note that the decimal_from_longest / decimal_from_ulongest routines
are actually more powerful than decimal_from_integral: the old routine
would only accept integer *types* of at most four bytes size, while
the new routines accept all integer *values* that fit in an [u]int32_t,
no matter which type they came from. The DFP tests are updated to
allow for this larger range of integers that can be converted.

PR21167, relocation sections not included in groups
This fixes a wart I've known about for years, but haven't done
anything about because BFD treats relocation sections as an adjunct to
the section they relocate. SHF_GROUP on the section thus implicitly
applies to its relocation section(s), but it is an error that the
reloc sections aren't part of the group.
Like many patches to gas, this wasn't as straightforward as it could
be due to a number of backends, i386, cr16 and others, removing relocs
in tc_get_reloc rather than marking them as "done" earlier in
md_apply_reloc. So it isn't possible for the group support to
reliably detect the presence of relocs by looking at fixups earlier
than write_relocs. However the group support needs to create
signature symbols, and that must be done before the symbol table is
frozen, before write_relocs. So split off the group sizing from
elf_adjust_symtab and put it in elf_frob_file_after_relocs.
