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

Enumerator
NewDef_Shift	Shift count to bypass PPC970 flags.
XFormMemOp	This instruction is an X-Form memory operation.
Prefixed	This instruction is prefixed.
SExt32To64	This instruction produced a sign extended result.
ZExt32To64	This instruction produced a zero extended result.

PPC970_Unit

enum llvm::PPCII::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

TOF

enum llvm::PPCII::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 and for PIC calls on 32-bit 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_PCREL_FLAG	MO_PCREL_FLAG - If this bit is set, the symbol reference is relative to the current instruction address(pc), e.g., var@pcrel. Fixup is VK_PCREL.
MO_GOT_FLAG	MO_GOT_FLAG - If this bit is set the symbol reference is to be computed via the GOT. For example when combined with the MO_PCREL_FLAG it should produce the relocation @got@pcrel. Fixup is VK_PPC_GOT_PCREL.
MO_PCREL_OPT_FLAG
MO_TLSGD_FLAG	MO_TLSGD_FLAG - If this bit is set the symbol reference is relative to TLS General Dynamic model for Linux and the variable offset of TLS General Dynamic model for AIX.
MO_TPREL_FLAG	MO_TPREL_FLAG - If this bit is set, the symbol reference is relative to the thread pointer and the symbol can be used for the TLS Initial Exec and Local Exec models.
MO_TLSLD_FLAG	MO_TLSLD_FLAG - If this bit is set the symbol reference is relative to TLS Local Dynamic model.
MO_TLSGDM_FLAG	MO_TLSGDM_FLAG - If this bit is set the symbol reference is relative to the region handle of TLS General Dynamic model for AIX.
MO_GOT_TLSGD_PCREL_FLAG	MO_GOT_TLSGD_PCREL_FLAG - A combintaion of flags, if these bits are set they should produce the relocation @got@tlsgd@pcrel. Fix up is VK_PPC_GOT_TLSGD_PCREL
MO_GOT_TLSLD_PCREL_FLAG	MO_GOT_TLSLD_PCREL_FLAG - A combintaion of flags, if these bits are set they should produce the relocation @got@tlsld@pcrel. Fix up is VK_PPC_GOT_TLSLD_PCREL
MO_GOT_TPREL_PCREL_FLAG	MO_GOT_TPREL_PCREL_FLAG - A combintaion of flags, if these bits are set they should produce the relocation @got@tprel@pcrel. Fix up is VK_PPC_GOT_TPREL_PCREL
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
