Strive for clarity by simplifying code expressions and reducing unnecessary complexity. Complex or verbose expressions decrease readability and increase the chance of errors during maintenance.
Key simplification practices:
// Simplified: PrecodeMachineDescriptor::Init(&g_cdacPlatformMetadata.precode);
2. **Use appropriate types** - Prefer language-native types for internal details:
```cpp
// Less appropriate for internal usage:
Volatile<BOOL> g_GCBridgeActive = FALSE;
// Better:
Volatile<bool> g_GCBridgeActive = false;
// Flattened and clearer: bool doInterpret = false; if ((g_interpModule != NULL) && (methodInfo->scope == g_interpModule)) doInterpret = true;
4. **Use parentheses in logical expressions** per coding guidelines:
```cpp
// Incorrect:
if (ins == INS_rcl_N || ins == INS_rcr_N || ins == INS_rol_N || ins == INS_ror_N)
// Correct:
if ((ins == INS_rcl_N) || (ins == INS_rcr_N) || (ins == INS_rol_N) || (ins == INS_ror_N))
// Extract to helper: emitMoveIfZeroImmediate(retReg, op1->GetRegNum(), attr);
6. **Collapse related conditionals** into helper functions:
```cpp
// Verbose:
if (IsAVXVNNIInstruction(ins) || IsAVXVNNIINT8Instruction(ins) || IsAVXVNNIINT16Instruction(ins))
// Better:
if (IsAvxVnniFamilyInstruction(ins))
Simpler code is easier to read, test, and maintain.
