Member Function Documentation

void AsmPrinter::SwitchToTextSection	(	const char *	NewSection,
		const GlobalValue *	GV = `NULL`
	)

SwitchToTextSection - Switch to the specified section of the executable if we are not already in it! If GV is non-null and if the global has an explicitly requested section, we switch to the section indicated for the global instead of NewSection.

If the new section is an empty string, this method forgets what the current section is, but does not emit a .section directive.

This method is used when about to emit executable code.

SwitchToTextSection - Switch to the specified text section of the executable if we are not already in it!

void AsmPrinter::SwitchToDataSection	(	const char *	NewSection,
		const GlobalValue *	GV = `NULL`
	)

SwitchToDataSection - Switch to the specified section of the executable if we are not already in it! If GV is non-null and if the global has an explicitly requested section, we switch to the section indicated for the global instead of NewSection.

If the new section is an empty string, this method forgets what the current section is, but does not emit a .section directive.

This method is used when about to emit data. For most assemblers, this is the same as the SwitchToTextSection method, but not all assemblers are the same.

SwitchToDataSection - Switch to the specified data section of the executable if we are not already in it!

void AsmPrinter::EmitAlignment	(	unsigned	NumBits,
		const GlobalValue *	GV = `0`,

		bool	UseFillExpr = `true`
	)			const

EmitAlignment - Emit an alignment directive to the specified power of two boundary. For example, if you pass in 3 here, you will get an 8 byte alignment. If a global value is specified, and if that global has an explicit alignment requested, it will unconditionally override the alignment request. However, if ForcedAlignBits is specified, this value has final say: the ultimate alignment will be the max of ForcedAlignBits and the alignment computed with NumBits and the global. If UseFillExpr is true, it also emits an optional second value FillValue which the assembler uses to fill gaps to match alignment for text sections if the has specified a non-zero fill value.

The algorithm is: Align = NumBits; if (GV && GV->hasalignment) Align = GV->getalignment(); Align = std::max(Align, ForcedAlignBits);
