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

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.

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

enum llvm::PPCII::TOF

Target Operand Flag enum.

Enumerator
MO_NO_FLAG
MO_DARWIN_STUB	MO_DARWIN_STUB - On a symbol operand "FOO", this indicates that the reference is actually to the "FOO$stub" symbol. This is used for calls and jumps to external functions on Tiger and earlier.
MO_PIC_FLAG	MO_PIC_FLAG - If this bit is set, the symbol reference is relative to the function's picbase, e.g. lo16(symbol-picbase).
MO_NLP_FLAG	MO_NLP_FLAG - If this bit is set, the symbol reference is actually to the non_lazy_ptr for the global, e.g. lo16(symbol$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
