◆ mapToDWARFAddrSpace()

int llvm::AMDGPU::mapToDWARFAddrSpace ( unsigned LLVMAddrSpace )

constexpr

If LLVMAddressSpace has a corresponding DWARF encoding, return it; otherwise return the sentinel value -1 to indicate no such mapping exists.

This maps private/scratch to the focused lane view.

These mappings must be kept in sync with llvm/docs/AMDGPUUsage.rst table "AMDGPU DWARF Address Space Mapping".

Note: This could return std::optional<int> but that would require an extra #include.

◆ maskShiftGet()

const MCExpr * llvm::AMDGPU::maskShiftGet	(	const MCExpr *	Val,

		uint32_t	Shift,

inline

Provided with the MCExpr * Val, uint32 Mask and Shift, will return the right shifted and masked, in said order of operations, MCExpr * created within the MCContext Ctx.

For example, given MCExpr *Val, Mask == 0xf, Shift == 6 the returned MCExpr

will be the equivalent of (Val >> 6) & 0xf

Provided with the MCExpr * Val, uint32 Mask and Shift, will return the masked and left shifted, in said order of operations, MCExpr * created within the MCContext Ctx.

For example, given MCExpr *Val, Mask == 0xf, Shift == 6 the returned MCExpr

will be the equivalent of (Val & 0xf) << 6
