Detailed Description

PPCII - This namespace holds all of the PowerPC target-specific per-instruction flags.

These must match the corresponding definitions in PPC.td and PPCInstrFormats.td.

Enumeration Type Documentation

◆ anonymous enum

anonymous enum
Enumerator
PPC970_First 

PPC970_First - This instruction starts a new dispatch group, so it will always be the first one in the group.

PPC970_Single 

PPC970_Single - This instruction starts a new dispatch group and terminates it, so it will be the sole instruction in the group.

PPC970_Cracked 

PPC970_Cracked - This instruction is cracked into two pieces, requiring two dispatch pipes to be available to issue.

PPC970_Shift 

PPC970_Mask/Shift - This is a bitmask that selects the pipeline type that an instruction is issued to.

PPC970_Mask 

Definition at line 30 of file PPCInstrInfo.h.

◆ anonymous enum

anonymous enum
Enumerator
NewDef_Shift 

Shift count to bypass PPC970 flags.

UseVSXReg 

The VSX instruction that uses VSX register (vs0-vs63), instead of VMX register (v0-v31).

Definition at line 65 of file PPCInstrInfo.h.

◆ PPC970_Unit

Enumerator
PPC970_Pseudo 

These are the various PPC970 execution unit pipelines.

Each instruction is one of these.

PPC970_FXU 
PPC970_LSU 
PPC970_FPU 
PPC970_CRU 
PPC970_VALU 
PPC970_VPERM 
PPC970_BRU 

Definition at line 52 of file PPCInstrInfo.h.

◆ TOF

Target Operand Flag enum.

Enumerator
MO_NO_FLAG 
MO_PLT 

On a symbol operand "FOO", this indicates that the reference is actually to "FOO@plt".

This is used for calls and jumps to external functions on for PIC calls on Linux and ELF systems.

MO_PIC_FLAG 

MO_PIC_FLAG - If this bit is set, the symbol reference is relative to the function's picbase, e.g.

lo16(symbol-picbase).

MO_NLP_FLAG 

MO_NLP_FLAG - If this bit is set, the symbol reference is actually to the non_lazy_ptr for the global, e.g.

lo16(symbol$non_lazy_ptr-picbase).

MO_NLP_HIDDEN_FLAG 

MO_NLP_HIDDEN_FLAG - If this bit is set, the symbol reference is to a symbol with hidden visibility.

This causes a different kind of non-lazy-pointer to be generated.

MO_ACCESS_MASK 

The next are not flags but distinct values.

MO_LO 

MO_LO, MO_HA - lo16(symbol) and ha16(symbol)

MO_HA 
MO_TPREL_LO 
MO_TPREL_HA 
MO_DTPREL_LO 

These values identify relocations on immediates folded into memory operations.

MO_TLSLD_LO 
MO_TOC_LO 
MO_TLS
