Some architectures contain registers that share the same physical location. A notable example is the X86 platform. For instance, in the X86 architecture, @@ -1627,7 +1627,7 @@ def : Pat<(i32 imm:$imm), bits. These physical registers are marked as aliased in LLVM. Given a particular architecture, you can check which registers are aliased by inspecting its RegisterInfo.td file. Moreover, the method - TargetRegisterInfo::getAliasSet(p_reg) returns an array containing + MCRegisterInfo::getAliasSet(p_reg) returns an array containing all the physical registers aliased to the register p_reg.
Physical registers, in LLVM, are grouped in Register Classes.
