5 years agoReplace std::to_string for integers with optimized version
Jonathan Wakely [Wed, 12 Jun 2019 14:52:02 +0000 (15:52 +0100)]
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.

5 years ago[arm] Implement usadv16qi and ssadv16qi standard names
Przemyslaw Wirkus [Wed, 12 Jun 2019 08:27:59 +0000 (08:27 +0000)]
[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:

5 years agocompiler: make escape analysis work with imported inlineable functions
Ian Lance Taylor [Mon, 10 Jun 2019 19:30:21 +0000 (19:30 +0000)]
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.
