Is inline assembly language slower than native C++ code?
...hecking for non-overlap if you omit __restrict). SSE2 is baseline for x86-64, and with shuffling SSE2 can do 2x 32-bit multiplies at once (producing 64-bit products, hence the shuffling to put the results back together). godbolt.org/z/r7F_uo. (SSE4.1 is needed for pmulld: packed 32x32 => 32-bit...
Why does this method print 4?
...Windows has a default stack size of 320k in the 32-bit VM and 1024k in the 64-bit VM. You can read more here.
You can run using different stack sizes and you will see different values of cnt before the stack overflows-
