Gold plugins may wish to further process an input file added by a plugin. For
example, the plugin may need to assign a unique segment for sections in a
plugin-generated input file. This patch adds a plugin callback that the linker
will call when reading symbols from a new input file added after the
all_symbols_read event (i.e. an input file added by a plugin).

For the most part, testcases under gcc.target/arm/cmse/baseline and
gcc.target/arm/cmse/mainline are duplicate copies with only different
dejagnu directives. Although there is no requirement for them to be
similar, having them both identical allow to compare the code generated
and make it easier in case of change in code generation to both
architecture to update the testcases (if one needs updating so does the
other).
Similarly all the tests in gcc.target/arm/cmse/mainline/<floatabi> have
the same source but are duplicate copies.
This patch moves all the code in the tests to a parent directory:
gcc.target/arm/cmse for tests shared by Armv8-M Baseline and Mainline
and gcc.target/arm/cmse/mainline for tests *only* shared by the various
float ABI of Armv8-M Mainline. C includes are then used where the code
used to sit.
Note that the cmse-13.c test used to differ slightly between
architectures and float ABI tested in the first floating-point constant
passed to bar: sometimes 1.0 and sometimes 3.0. This patch settles on
3.0 to not confuse with the 1.0 constant used to clear VFP registers in
some of the configurations.

When gcc-dg-runtest is used to run a test the test is run several times
with different options. For clarity of the log, the test infrastructure
then append the options to the testname. This means that all the code
that must deal with the testcase itself (eg. removing the output files
after the test has run) needs to remove the option name.
There is already a pattern (see below) for this in several place of the
testsuite framework but it is also missing in many places. This patch
fixes all of these places. The pattern is as follows:
set testcase [testname-for-summary]
; The name might include a list of options; extract the file name.
set testcase [lindex $testcase 0]

A number of instructions are output in assembler form by
output_return_instruction () when compiling a function with the
cmse_nonsecure_entry attribute for Armv8-M Mainline with hardfloat float
ABI. However, the corresponding thumb2_cmse_entry_return insn pattern
does not account for all these instructions in its computing of the
length of the instruction.
This may lead GCC to use the wrong branching instruction due to
incorrect computation of the offset between the branch instruction's
address and the target address.
This commit fixes the mismatch between what output_return_instruction ()
does and what the pattern think it does and adds a note warning about
mismatch in the affected functions' heading comments to ensure code does
not get out of sync again.
Note: no test is provided because the C testcase is fragile (only works
on GCC 6) and the extracted RTL test fails to compile due to bugs in the
RTL frontend (PR82815 and PR82817)

This patch adds a target selector to say whether it's possible to
align a local variable to the target's preferred vector alignment.
This can be false for large vectors if the alignment is only
a preference and not a hard requirement (and thus if there is no
need to support a stack realignment mechanism).

This patch adds a target selector that says whether we can ever
generate an "unaligned" accesses, where "unaligned" is relative
to the target's preferred vector alignment. This is already true if:
vect_no_align && { ! vect_hw_misalign }
i.e. if the target doesn't have any alignment mechanism and also
doesn't allow unaligned accesses. It is also true (for the things
tested by gcc.dg/vect) if the target only wants things to be aligned
to an element; in that case every normal scalar access is "vector aligned".

This patch adds a target selector for targets whose
preferred_vector_alignment is the alignment of one element. We'll never
peel in that case, and the step of a loop that operates on normal (as
opposed to packed) elements will always divide the preferred alignment.

SLP load permutation fails if any individual permutation requires more
than two vector inputs. For 128-bit vectors, it's possible to permute
3 contiguous loads of 32-bit and 8-bit elements, but not 16-bit elements
or 64-bit elements. The results are reversed for 256-bit vectors,
and so on for wider vectors.
This patch adds a routine that tests whether a permute will require
three vectors for a given vector count and element size, then adds
vect_perm3_* target selectors for the cases that we currently use.

Several vector tests are sensitive to the vector size. This patch adds
a VECTOR_BITS macro to tree-vect.h to select the expected vector size
and uses it to influence iteration counts and array sizes. The tests
keep the original values if the vector size is small enough.
For now VECTOR_BITS is always 128, but the SVE patches add other values.

The recent gen_vec_duplicate patches used CONST_VECTOR for all
constants, but the documentation says:
@findex const_vector
@item (const_vector:@var{m} [@var{x0} @var{x1} @dots{}])
Represents a vector constant. The square brackets stand for the vector
containing the constant elements. @var{x0}, @var{x1} and so on are
the @code{const_int}, @code{const_double} or @code{const_fixed} elements.
Both the AArch32 and AArch64 ports relied on the elements having
this form and would ICE if the element was something like a CONST
instead. This showed up as a failure in vect-126.c for both arm-eabi
and aarch64-elf (but not aarch64-linux-gnu, which is what the series
was tested on).
The two obvious options were to redefine CONST_VECTOR to accept all
constants or make gen_vec_duplicate honour the existing documentation.
It looks like other code also assumes that integer CONST_VECTORs contain
CONST_INTs, so the patch does the latter.
I deliberately didn't add an assert to gen_const_vec_duplicate
because it looks like the SPU port *does* expect to be able to create
CONST_VECTORs of symbolic constants.
Also, I think the list above should include const_wide_int for vectors
of TImode and wider.
The new routine takes a mode for consistency with the generators,
and because I think it does make sense to accept all constants for
variable-length:
(const (vec_duplicate ...))
rather than have some rtxes for which we instead use:
(vec_duplicate (const ...))
