static MCCFIInstruction createDefCfaRegister(MCSymbol *L, unsigned Register, SMLoc Loc={})

.cfi_def_cfa_register modifies a rule for computing CFA.

static MCCFIInstruction createUndefined(MCSymbol *L, unsigned Register, SMLoc Loc={})

.cfi_undefined From now on the previous value of Register can't be restored anymore.

static MCCFIInstruction createRestore(MCSymbol *L, unsigned Register, SMLoc Loc={})

.cfi_restore says that the rule for Register is now the same as it was at the beginning of the functi...

static MCCFIInstruction createRegister(MCSymbol *L, unsigned Register1, unsigned Register2, SMLoc Loc={})

.cfi_register Previous value of Register1 is saved in register Register2.

static MCCFIInstruction cfiDefCfa(MCSymbol *L, unsigned Register, int64_t Offset, SMLoc Loc={})

.cfi_def_cfa defines a rule for computing CFA as: take address from Register and add Offset to it.

static MCCFIInstruction createOffset(MCSymbol *L, unsigned Register, int64_t Offset, SMLoc Loc={})

.cfi_offset Previous value of Register is saved at offset Offset from CFA.

static MCCFIInstruction createNegateRAStateWithPC(MCSymbol *L, SMLoc Loc={})

.cfi_negate_ra_state_with_pc AArch64 negate RA state with PC.

static MCCFIInstruction createNegateRAState(MCSymbol *L, SMLoc Loc={})

.cfi_negate_ra_state AArch64 negate RA state.

static MCCFIInstruction cfiDefCfaOffset(MCSymbol *L, int64_t Offset, SMLoc Loc={})

.cfi_def_cfa_offset modifies a rule for computing CFA.

static MCCFIInstruction createEscape(MCSymbol *L, StringRef Vals, SMLoc Loc={}, StringRef Comment="")

.cfi_escape Allows the user to add arbitrary bytes to the unwind info.

static MCCFIInstruction createWindowSave(MCSymbol *L, SMLoc Loc={})

.cfi_window_save SPARC register window is saved.

static MCCFIInstruction createAdjustCfaOffset(MCSymbol *L, int64_t Adjustment, SMLoc Loc={})

.cfi_adjust_cfa_offset Same as .cfi_def_cfa_offset, but Offset is a relative value that is added/subt...

static MCCFIInstruction createSameValue(MCSymbol *L, unsigned Register, SMLoc Loc={})

.cfi_same_value Current value of Register is the same as in the previous frame.

Describe properties that are true of each instruction in the target description file.

Wrapper class representing physical registers. Should be passed by value.

MCSymbol - Instances of this class represent a symbol name in the MC file, and MCSymbols are created ...
