Darwin, Driver - Improve processing of macosx-version-min=
For PR target/63810 some improvements were made in the parsing of
the version string at the point it's used to define the built-in
__ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__. This is fine, but the
specs processing also uses the version, and specs version-compare
doesn't like leading zeros on components. This means that while we
succeed in processing -mmacosx-version-min=010.00002.000099 on compile
lines, it fails for any other line that uses the value as part of a spec
(in particular, link lines fail).
To fix this, we need to apply a bit of clean-up to the version that's
presented to the driver, and push that back into the command line opts.
The value can come from four places:
1. User-entered on the command line
2. User-entered as MACOSX_DEPLOYMENT_TARGET= environment var.
3. Absent those two
3a For self-hosting systems, look-up from the kernel
3b For cross-compilers, as a default supplied at configure time.
We apply the clean-up to all 4 (although it shouldn't really be needed
for the cases under 3).
We also supply a test-case that adapts to the target-version of the
system, so that the link requirements are met by the SDK in use (if you
try to link i686-darwin9 on an x86-64-darwin18 SDK, it will fail).

Replace std::to_string for integers with optimized version
The std::to_chars functions from C++17 can be used to implement
std::to_string with much better performance than calling snprintf. Only
the __detail::__to_chars_len and __detail::__to_chars_10 functions are
needed for to_string, because it always outputs base 10 representations.
The return type of __detail::__to_chars_10 should not be declared before
C++17, so the function body is extracted into a new function that can be
reused by to_string and __detail::__to_chars_10.
The existing tests for to_chars rely on to_string to check for correct
answers. Now that they use the same code that doesn't actually ensure
correctness, so add new tests for std::to_string that compare against
printf output.

[arm] Implement usadv16qi and ssadv16qi standard names
This patch implements the usadv16qi and ssadv16qi standard names for arm.
The V16QImode variant is important as it is the most commonly used pattern:
reducing vectors of bytes into an int.
The midend expects the optab to compute the absolute differences of operands 1
and 2 and reduce them while widening along the way up to SImode. So the inputs
are V16QImode and the output is V4SImode.
I've based my solution on Aarch64 usadv16qi and ssadv16qi standard names
current implementation (r260437). This solution emits below sequence of
instructions:
VABDL.u8 tmp, op1, op2 # op1, op2 lowpart
VABAL.u8 tmp, op1, op2 # op1, op2 highpart
VPADAL.u16 op3, tmp
So, for the code:
$ arm-none-linux-gnueabihf-gcc -S -O3 -march=armv8-a+simd -mfpu=auto -mfloat-abi=hard usadv16qi.c -dp
#define N 1024
unsigned char pix1[N];
unsigned char pix2[N];
int
foo (void)
{
int i_sum = 0;
int i;
for (i = 0; i < N; i++)
i_sum += __builtin_abs (pix1[i] - pix2[i]);
return i_sum;
}
we now generate on arm:

Heap_expression::do_get_backend emits an unconditional write

This CL changes it to use a write barrier for the assignment only

call gcWriteBarrier instead of typedmemmove for pointer-shaped

For this to work, Function::build needs to be adjusted so that
Heap_expression::do_get_backend is called when there is a parent

compiler: make escape analysis work with imported inlineable functions
The escape analysis was written before we import inlineable
function bodies, and in some places it skipped functions that are
not in the local package. Now that there are imported function
bodies, make the escape analysis work with them.
Note that it is necessary for the escape analysis to run on
imported function bodies, even if they are already tagged. The
tags only have the information of the parameters (receiver,
results), but not the internal nodes, e.g. local variables. We
still need to do the analysis to get all the information. (In the
future maybe we could export/import escape info for internal
nodes also, then we don't need to redo the analysis.)
Also add assertions to ensure that if we analyze the same
function in multiple places, they'd better agree with each other.

This reproduces the original ICE fixed by r178857 (tested at r178852 and
r178860), without depending on a libstdc++ header that keeps changing.
The number of errors differs between C++14 and C++17 modes, so the fixed
test uses dg-excess-errors to match any number of them. The precise
errors aren't what's being tested for here anyway, the point of the test
is to verify the ICE in PR 50391 is fixed.
