DispatcherPowerpc.h

// Semantics for 32-bit Motorola-IBM PowerPC microprocessors using ROSE instruction semantics API2
// This code was derived from $ROSE/projects/assemblyToSourceAst/powerpcInstructionSemantics.h,
// which is mostly a copy of $ROSE/projects/SemanticSignatureVectors/powerpcInstructionSemantics.h
//
// The ROSE style guide indicates that PowerPC, when used as part of a symbol in ROSE source code,
// should be capitalized as "Powerpc" (e.g., "DispatcherPowerpc", the same rule that consistently
// capitializes x86 as "DispatcherX86").
