libcpp: move line typedef and column-numbering comment to top of file
The description of our 1-based column-numbering convention was in
a non-obvious place withn line-map.h; this patch moves it to the top
of that header.
libcpp/ChangeLog:
* include/line-map.h (linenum_type): Move this typedef and the
comment describing column numbering to near the top of the file.

[testsuite/ARM] Consolidate sources for cmse tests
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.

[testsuite] Fix retrieval of testname
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]

[ARM] Fix cmse_nonsecure_entry return insn size
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)

Add VECTOR_BITS to tree-vect.h
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.

Consistently use asm volatile ("" ::: "memory") in vect tests
The vectoriser tests used a combination of:
1) if (impossible condition) abort ();
2) volatile int x; ... *x = ...;
3) asm volatile ("" ::: "memory");
to prevent vectorisation of a set-up loop. The problem with 1) is that
the compiler can often tell that the condition is false and optimise
it away before vectorisation.
This was already happening in slp-perm-9.c, which is why the test was
expecting one loop to be vectorised even when the required permutes
weren't supported. It becomes a bigger problem with SVE, which is
able to vectorise more set-up loops.
The point of this patch is therefore to replace 1) with something else.
2) should work most of the time, but we don't usually treat non-volatile
accesses as aliasing unrelated volatile accesses, so I think in principle
we could split the loop into one that does the set-up and one that does
the volatile accesses. 3) seems more robust because it's also a wild
read and write.
The patch therefore tries to replace all instances of 1) and 2) with 3).

Be stricter about CONST_VECTOR operands
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 ...))

Base subreg rules on REGMODE_NATURAL_SIZE rather than UNITS_PER_WORD
Originally subregs operated at the word level and subreg offsets
were measured in words. The offset units were later changed from
words to bytes (SUBREG_WORD became SUBREG_BYTE), but the fundamental
assumption that subregs should operate at the word level remained.
Whether (subreg:M1 (reg:M2 R2) N) is well-formed depended on the
way that M1 and M2 partitioned into words and whether the subword
part of N represented a lowpart. However, some questions depended
instead on the macro REGMODE_NATURAL_SIZE, which was introduced
as part of the patch that moved from SUBREG_WORD to SUBREG_BYTE.
It is used to decide whether setting (subreg:M1 (reg:M2 R2) N)
clobbers all of R2 or just part of it (df_read_modify_subreg).
Using words doesn't really make sense for modern vector
architectures. Vector registers are usually bigger than
a word and:
(a) setting the scalar lowpart of them usually clobbers the
rest of the register (contrary to the subreg rules,
where only the containing words should be clobbered).
(b) high words of vector registers are often not independently
addressable, even though that's what the subreg rules expect.
This patch therefore uses REGMODE_NATURAL_SIZE instead of
UNITS_PER_WORD to determine the size of the independently
addressable blocks in an inner register.
This is needed for SVE because the number of words in a vector
mode isn't known at compile time, so isn't a sensible basis
for calculating the number of registers.
The only existing port to define REGMODE_NATURAL_SIZE is
64-bit SPARC, where FP registers are 32 bits. (This is the
opposite of the use case for SVE, since the natural division
is smaller than a word.) I compiled the testsuite before and
after the patch for sparc64-linux-gnu and the only test whose
assembly changed was g++.dg/debug/pr65678.C, where the order
of two independent stores was reversed and where a different
register was picked for one pseudo. The new code was
otherwise equivalent to the old code.
