This is an overloaded intrinsic. You can use llvm.part.select -on any integer bit width.

The 'llvm.part.select' family of intrinsic functions selects a -range of bits from an integer value and returns them in the same bit width as -the original value.
- -The first argument, %val and the result may be integer types of -any bit width but they must have the same bit width. The second and third -arguments must be i32 type since they specify only a bit index.
- -The operation of the 'llvm.part.select' intrinsic has two modes -of operation: forwards and reverse. If %loBit is greater than -%hiBits then the intrinsic operates in reverse mode. Otherwise it -operates in forward mode.
-In forward mode, this intrinsic is the equivalent of shifting %val -right by %loBit bits and then ANDing it with a mask with -only the %hiBit - %loBit bits set, as follows:
-In reverse mode, a similar computation is made except that the bits are -returned in the reverse order. So, for example, if X has the value -i16 0x0ACF (101011001111) and we apply -part.select(i16 X, 8, 3) to it, we get back the value -i16 0x0026 (000000100110).
-This is an overloaded intrinsic. You can use llvm.part.set -on any integer bit width.

The 'llvm.part.set' family of intrinsic functions replaces a range -of bits in an integer value with another integer value. It returns the integer -with the replaced bits.
- -The first argument, %val, and the result may be integer types of -any bit width, but they must have the same bit width. %val is the value -whose bits will be replaced. The second argument, %repl may be an -integer of any bit width. The third and fourth arguments must be i32 -type since they specify only a bit index.
- -The operation of the 'llvm.part.set' intrinsic has two modes -of operation: forwards and reverse. If %lo is greater than -%hi then the intrinsic operates in reverse mode. Otherwise it -operates in forward mode.
- -For both modes, the %repl value is prepared for use by either -truncating it down to the size of the replacement area or zero extending it -up to that size.
- -In forward mode, the bits between %lo and %hi (inclusive) -are replaced with corresponding bits from %repl. That is the 0th bit -in %repl replaces the %loth bit in %val and etc. up -to the %hith bit.
- -In reverse mode, a similar computation is made except that the bits are -reversed. That is, the 0th bit in %repl replaces the -%hi bit in %val and etc. down to the %loth bit.
