--- Comment #31 from Martin Sebor <msebor at gcc dot gnu.org> ---
With GCC 7.0 I don't see much of a difference between the code emitted for the
original test case and for the smaller one from comment #19. Can this bug be
resolved or am I missing something?
For convenience, here are both test cases:
#if !ORIGINAL
void bar (short *array,
short b1, short b2, short b3, short b4,
short b5, short b6, short b7, short b8)
{
array[0] = b1 && b2 && b3 && b4 && b5 && b6 && b7 && b8;
array[1] = b1 && b2 && b3 && b4 && b5 && b6 && b7 && b8;
}
#else
void bar (short *array,
short b1, short b2, short b3, short b4,
short b5, short b6, short b7, short b8,
short b9, short b10, short b11, short b12)
{
array[0] = b1 && b2 && b3 && b4 && b5 && b6 && b7 && b8 && b9 && b10 && b11
&& b12;
array[1] = b1 && b2 && b3 && b4 && b5 && b6 && b7 && b8 && b9 && b10 && b11
&& b12;
array[2] = b1 && b2 && b3 && b4 && b5 && b6 && b7 && b8 && b9 && b10 && b11
&& b12;
array[3] = b1 && b2 && b3 && b4 && b5 && b6 && b7 && b8 && b9 && b10 && b11
&& b12;
array[4] = b1 && b2 && b3 && b4 && b5 && b6 && b7 && b8 && b9 && b10 && b11
&& b12;
array[5] = b1 && b2 && b3 && b4 && b5 && b6 && b7 && b8 && b9 && b10 && b11
&& b12;
array[6] = b1 && b2 && b3 && b4 && b5 && b6 && b7 && b8 && b9 && b10 && b11
&& b12;
array[7] = b1 && b2 && b3 && b4 && b5 && b6 && b7 && b8 && b9 && b10 && b11
&& b12;
array[8] = b1 && b2 && b3 && b4 && b5 && b6 && b7 && b8 && b9 && b10 && b11
&& b12;
array[9] = b1 && b2 && b3 && b4 && b5 && b6 && b7 && b8 && b9 && b10 && b11
&& b12;
array[10] = b1 && b2 && b3 && b4 && b5 && b6 && b7 && b8 && b9 && b10 && b11
&& b12;
}
#endif
