Tom de Vries 4b557bcc0d [nvptx] Assert fork has at most one join in nvptx_find_par
With the test-case of PR90009 we run into a SIGSEGV in nvptx_neuter_pars,
because par->join_insn and par->join_block are NULL.

Detect this problem earlier, by adding an assert in nvptx_find_par that
asserts that a fork cannot be paired with more than one join.

Build and tested on x86_64 with nvptx accelerator enabled.

Jonathan Wakely cd0b94e650 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.

Przemyslaw Wirkus 84ae721396 [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:
