Christian R. Helmrich 71f2a4ab92 fix TNS regression 2022-07-22 10:00:39 +00:00
John Regan b10947e9e9 Correct regression introduced in ac021570 
In ac021570, a series of 4 int8_t was cast into an int32_t t, by
casting each int8_t into a uint32_t and shifting by an appropriate
number of bits, then casting back into int32_t.

It seems on GCC, when casting a negative int8_t into a uint32_t,
the sign bit is extended into the rest of the value. So you can wind up
with different values based on whether the integer is constructed using
little-endian ordering or big-endian.

Since the goal of the code is to just check if the values are the same
or not, this is replaced with a memcmp call.

John Regan ac021570a3 fix undefined behavior: unaligned read 
Casting a type pointer into a larger type pointer requires
alignment. This replaces the unportable code with a portable
equivalent.

John Regan 5cc33e5af7 fix undefined behavior: left shift a negative integer 
C/C++ leaves left-shifting a negative integer up to the compiler
implementation.

On most platforms, left-shifting a negative integer is the same as
casting to the unsigned equivalent, then casting back into the signed
type.

This replaces the left-shift with the mathematical equivalent and avoids
the undefined behavior.

Ideally this should be performed for any case of left-shifting a signed
type, but this commit only covers cases picked up by the undefined
behavior sanitizer.

John Regan c2665b890c Fix undefined behavior: shift exponent is too large 
Previously, the bestOrder value was being decremented inside
the loop. This caused the following:

In the case where the loop enters with bestOrder == 2, the
value is decremented to 1, and the following operations occurs:

m_tnsPredGains[channelIndex] >> (8 * bestOrder - 16)

bestOrder being 1 - this evaluates to (8 - 16), causing an integer
underflow, and a right shift by 4294967288. m_tnsPredGains is a
32-bit unsigned int, right-shifting by a value > 32 is undefined.

I think the intent of the loop conditional is to avoid running the
calculation with bestOrder == 1 - as far as I can tell, this is
the lowest possible value.

By re-arranging the comparison and using a prefix decrement,
we can exhibit the same behavior but avoid the case where
bestOrder == 1 within the loop body.
