- Is there a use for this in LLVM?
Fixed Point Facility:
- Add PC Immediate Shifted: addpcis subpcis
. Thinking to use it on PC relative addressing mode?
- 64-bit Fixed-Point Multiply-Add Low DWord: maddld
. SDAG:
(set i64:$rD, (add (mul $rA, $rB), $rC))
- 64-bit Fixed-Point Multiply-Add High-DWord/High-DWord-Unsigned: maddhd maddhdu

(set i64:$rD, (int_ppc_maddhdu i64:$rA, i64:$rB), i64:$rC))
- Modulo {Signed/Unsigned}-{Word/DWord}: modsw moduw modsd modud
. Map modulo signed to llvm srem, modulo unsigned to urem because each pair
has same semantics, as follows:
llvm srem:
1. This instruction returns the remainder of a division (where the result is
either zero or has the same sign as the dividend, op1)
2. Undefined behavior:
- <anything> % 0
- Overflow: e.g. -2147483648 % -1
In this case, the remainder doesnt actually overflow, but this rule
lets srem be implemented using instructions that return both the result
of the division and the remainder.
Modulo Signed:
1. remainder = dividend - (quotient × divisor)
where
0 ≤ remainder < |divisor|, if the dividend ≥ 0
-|divisor| < remainder ≤ 0 , if the dividend < 0
2. Undefined behavior:
- <anything> % 0
- 0x8000_0000 % -1
. SDAG:
(set i32:$rD, (srem i32:$rA, i32:$rB)) // modsw
(set i32:$rD, (urem i32:$rA, i32:$rB)) // moduw
(set i64:$rD, (srem i64:$rA, i64:$rB)) // modsd

The quotient is not supplied as a result in modulo word (32-bit)
instructions
- Deliver A Random Number: darn
. Intrinsic?
(set i64:$rD, (int_ppc_darn i2:$L))
. Thinking for using it on c/c++ rand() implementation
- Extend-Sign Word and Shift Left Immediate: extswsli extswsli.
. SDAG:

- Set Boolean: setb
. Thinking to use it on:
