That way the common case where no NaNs are produced we can avoid the libgcc call and fall back to the
NaN handling stuff in libgcc if either components of the expansion are NaN.

The implementation is done in expand_complex_multiplication in tree-complex.c and the above expansion
will be done when optimising for -O1 and greater and when not optimising for size.
At -O0 and -Os the single call to libgcc will be emitted.

For the code:
__complex double
foo (__complex double a, __complex double b)
{
  return a * b;
}

We will now emit at -O2 for aarch64:
foo:
        fmul    d16, d1, d3
        fmul    d6, d1, d2
        fnmsub  d5, d0, d2, d16
        fmadd   d4, d0, d3, d6
        fcmp    d5, d4
        bvs     .L8
        fmov    d1, d4
        fmov    d0, d5

.L8:
        stp     x29, x30, [sp, -16]!
        mov     x29, sp
        bl      __muldc3
        ldp     x29, x30, [sp], 16
        ret

6 years agoUse char_span for return type of location_get_source_line
David Malcolm [Mon, 30 Apr 2018 15:01:56 +0000 (15:01 +0000)]
Use char_span for return type of location_get_source_line

location_get_source_line returns a const char * that isn't 0-terminated,
writing back a length through an int * param.

This is error-prone, as all call-sites have to take into account the
lack of 0-termination, and respect the length of the buffer.

It's cleaner to bundle together this pointer+length state into a class,
so this patch does so, reusing the "char_span" class that I introduced
in r250187 (as part of the fix for PR c/81405).
