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

TOF

enum llvm::PPCII::TOF

Target Operand Flag enum.

Enumerator
MO_NO_FLAG
MO_PLT	On PPC, the 12 bits are not enough for all target operand flags. Treat all PPC target flags as direct flags. To define new flag that is combination of other flags, add new enum entry instead of combining existing flags. See example MO_GOT_TPREL_PCREL_FLAG. 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_PCREL_OPT_FLAG - If this bit is set the operand is part of a PC Relative linker optimization.
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_TLSLDM_FLAG	MO_TLSLDM_FLAG - on AIX the ML relocation type is only valid for a reference to a TOC symbol from the symbol itself, and right now its only user is the symbol "_$TLSML". The symbol name is used to decide that the R_TLSML relocation is expected.
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_TLSGD_PCREL_FLAG = MO_PCREL_FLAG | MO_GOT_FLAG | MO_TLSGD_FLAG,
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_TLSLD_PCREL_FLAG = MO_PCREL_FLAG | MO_GOT_FLAG | MO_TLSLD_FLAG,
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_GOT_TPREL_PCREL_FLAG = MO_GOT_FLAG | MO_TPREL_FLAG | MO_PCREL_FLAG,
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	Symbol for VK_PPC_TLS fixup attached to an ADD instruction.
MO_PIC_HA_FLAG	MO_PIC_HA_FLAG = MO_PIC_FLAG | MO_HA.
MO_PIC_LO_FLAG	MO_PIC_LO_FLAG = MO_PIC_FLAG | MO_LO.
MO_TPREL_PCREL_FLAG	MO_TPREL_PCREL_FLAG = MO_PCREL_FLAG | MO_TPREL_FLAG.
MO_TLS_PCREL_FLAG	MO_TPREL_PCREL_FLAG = MO_PCREL_FLAG | MO_TLS.
MO_GOT_PCREL_FLAG	MO_GOT_PCREL_FLAG = MO_PCREL_FLAG | MO_GOT_FLAG.
