One effect of https://gcc.gnu.org/ml/gcc-patches/2019-09/msg00802.html
was to strengthen the sanity check in lra_assigns so that it checks
whether reg_renumber is consistent with the whole conflict set.
This duly tripped on csky for a pseudo that had been allocated
to the eliminated frame pointer. (csky doesn't have a separate
hard frame pointer.)
lra-lives uses:
/* Set of hard regs (except eliminable ones) currently live. */
static HARD_REG_SET hard_regs_live;
to track the set of live directly-referenced hard registers, and it
correctly implements the exclusion when setting up the initial set:
hard_regs_live &= ~eliminable_regset;
But later calls to make_hard_regno_live and make_hard_regno_dead
would process eliminable registers like other registers, recording
conflicts for them and potentially making them live. (Note that
after r266086, make_hard_regno_dead adds conflicts for registers
that are already marked dead.) I think this would have had the
effect of pessimising targets without a separate hard frame pointer.

As part of adding [[]]-style attributes, C2x adds the token :: for use
in scoped attribute names.
This patch adds corresponding support for that token in C to GCC. The
token is supported both for C2x and for older gnu* standards (on the
basis that extensions are normally supported in older gnu* versions;
people will expect to be able to use [[]] attributes, before C2x is
the default, without needing to use -std=gnu2x).
There are no cases in older C standards where the token : can be
followed by a token starting with : in syntactically valid sources;
the only cases the :: token could break in older standard C thus are
ones involving concatenation of pp-tokens where the result does not
end up as tokens (e.g., gets stringized). In GNU C extensions, the
main case where :: might appear in existing sources is in asm
statements, and the C parser is thus made to handle it like two
consecutive : tokens, which the C++ parser already does. A limited
test of various positionings of :: in asm statements is added to the
testsuite (in particular, to cover the syntax error when :: means too
many colons but a single : would be OK), but existing tests cover a
variety of styles there anyway.
Technically there are cases in Objective-C and OpenMP for which this
also changes how previously valid code is lexed: the objc-selector-arg
syntax allows multiple consecutive : tokens (although I don't think
they are particularly useful there), while OpenMP syntax includes
array section syntax such as [:] which, before :: was a token, could
also be written as [::> (there might be other OpenMP cases potentially
affected, I didn't check all the OpenMP syntax in detail). I don't
think either of those cases affects the basis for supporting the ::
token in all -std=gnu* modes, or that there is any obvious need to
special-case handling of CPP_SCOPE tokens for those constructs the way
there is for asm statements.
cpp_avoid_paste, which determines when spaces need adding between
tokens in preprocessed output where there wouldn't otherwise be
whitespace between them (e.g. if stringized), already inserts space
between : and : unconditionally, rather than only for C++, so no
change is needed there (but a C2x test is added that such space is
indeed inserted).
Bootstrapped with no regressions on x86-64-pc-linux-gnu.

Respect the `--enable-version-specific-runtime-libs' configuration
option in libada/, so that shared gnatlib libraries will be installed
in non-version-specific $(toolexeclibdir) if requested. In a
cross-compilation environment this helps setting up a consistent
sysroot, which can then be shared between the host and the target
system.
This lets one have `libgnarl-10.so' and `libgnat-10.so' installed in say
/usr/lib and /usr/$(target_alias)/lib for a native and a cross-build
respectively, rather than in /usr/lib/gcc/$(target_alias)/10.0.0/adalib.
Update the settings of $(toolexecdir) and $(toolexeclibdir), unused till
now, to keep the current arrangement in the version-specific case and
make the new option to be enabled by default, unlike with the other
target libraries, so as to keep existing people's build infrastructure
unaffected.
Of course if someone does use `--disable-version-specific-runtime-libs'
already, then the installation location of shared gnatlib libraries will
change, but presumably this is what they do want anyway as the current
situation where the option is ignored in libada/ only is an anomaly
really rather than one that is expected or desired.

For some reason, presumably historical, the `install-gnatlib' target for
the default multilib is invoked twice, once via the `ada.install-common'
target in `gcc/ada/gcc-interface/Make-lang.in' invoked from gcc/ and
again via the `install-libada' target in libada/.
Apart from doing the same twice this is actually harmful in sufficiently
parallelized `make' invocation, as the removal of old files performed
within the `install-gnatlib' recipe in the former case actually races
with the installation of new files done in the latter case, causing the
recipe to fail and abort, however non-fatally, having not completed the
installation of all the built files needed for the newly-built compiler
to work correctly.
This can be observed with a native `x86_64-linux-gnu' bootstrap:
make[4]: Entering directory '.../gcc/ada'
rm -rf .../lib/gcc/x86_64-linux-gnu/10.0.0/adalib
rm: cannot remove '.../lib/gcc/x86_64-linux-gnu/10.0.0/adalib': Directory not empty

make[2]: [.../gcc/ada/gcc-interface/Make-lang.in:829: ada.install-common] Error 2 (ignored)
which then causes missing files to be reported when an attempt is made
to use the newly-installed non-functional compiler to build a
`riscv-linux-gnu' cross-compiler:
(cd ada/bldtools/sinfo; gnatmake -q xsinfo ; ./xsinfo sinfo.h )
error: "ada.ali" not found, "ada.ads" must be compiled
error: "s-memory.ali" not found, "s-memory.adb" must be compiled

Depending on timing `.../lib/gcc/x86_64-linux-gnu/10.0.0/adainclude' may
cause an installation failure instead and the resulting compiler may be
non-functional in a different way.
Only invoke `install-gnatlib' from within gcc/ then if a legacy build
process is being used with libada disabled and gnatlib built manually
with `make -C gcc gnatlib'.

flag_omit_frame_pointer is set in machine-independent code depending
on the optimization level. It is then overridden in x86
target-specific code depending on a macro defined by
--enable-frame-pointer.
Uses of attribute optimize go through machine-independent overriding
of flag_omit_frame_pointer, but the x86-specific overriding code did
NOT cover this flag, so, even if the attribute does not change the
optimization level, flag_omit_frame_pointer may end up with a
different value, and prevent inlining because of incompatible flags,
as detected by the gcc.dg/ipa/iinline-attr.c test on an

Optimizing gcc.dg/torture/pr41094.c, the compiler computes the
constant value and short-circuits the whole thing. At -O0, however,
on 32-bit x86, the call to pow() remains, and the program compares the
returned value in a stack register, with excess precision, with the
exact return value expected from pow(). If libm's pow() returns a
slightly off result, the compare fails. If the value in the register
is stored in a separate variable, so it gets rounded to double
precision, and then compared, the compare passes.
It's not clear that the test was meant to detect libm's reliance on
rounding off the excess precision, but I guess it wasn't, so I propose
this slight change that enables it to pass regardless of the slight
inaccuracy of the C library in use.

A variable redeclaration or definition that provides additional type
information for it, e.g. outermost array bounds, is not reflected in
the debug information for the variable. With this patch, the debug
info of the variable specialization gets a type attribute with the
adjusted type.
This patch affects mostly only array bounds. However, when the
symbolic type used in a declaration and in a definition are different,
although they refer to the same type, debug information will end up
(correctly?) naming different symbolic types in the specification and
the definition. Also, when a readonly declaration of an array loses
the readonly flag at the definition because of the initializer, the
definition may end up referencing a type while the specification
refers to a const-qualified version of that type. If the type of the
variable is already const-qualified, e.g. an array of a const type,
the difference is meaningless.

diag-aka-1.c tests that:
struct T { int i; } T;
void *a;
T *t = a;
produces:
request for implicit conversion from 'void *' to 'T *' {aka 'struct T *'} ...
But printing an aka for the tag seems a bit redundant when the tag name
is the same as the typedef name. It's probably not going to be telling
the user anything they don't already know, and can be distracting if "T"
rather than "struct T" is the preferred choice for an exported interface.
This is even more true if the tag is anonymous; e.g.:
struct { int i; } T;
void *a;
T *t = a;
gives:
request for implicit conversion from 'void *' to 'T *' {aka 'struct <anonymous> *'}
Rather than just drop the test above, the patch instead tests for:
struct T { int i; } *T;

Given the following invalid arm_neon.h-based code:
float x;
int8x8_t y = x;
the error message we emit is pretty good:
incompatible types when initializing type 'int8x8_t' using type 'float'
But convert the types to pointers:
int8x8_t *ptr = &x;
and the message becomes:
initialization of '__vector(8) signed char *' from incompatible pointer type 'float *'
Although it's reasonably obvious what '__vector(8) signed char *' means,
it isn't valid C or C++ syntax and is quite far from what the user wrote,
so using 'int8x8_t *' would be better.
This patch therefore prints the type name of vectors that have one.
It's still OK to print the __vector syntax as an "aka", although I have
