Member Function Documentation

allocateCodeSection()

uint8_t * IRExecutionUnit::MemoryManager::allocateCodeSection ( uintptr_t  Size, unsigned  Alignment, unsigned  SectionID, llvm::StringRef  SectionName  )

override

Allocate space for executable code, and add it to the m_spaceBlocks map.

Parameters

[in]	Size	The size of the area.
[in]	Alignment	The required alignment of the area.
[in]	SectionID	A unique identifier for the section.

Returns

Allocated space.

allocateDataSection()

uint8_t * IRExecutionUnit::MemoryManager::allocateDataSection ( uintptr_t  Size, unsigned  Alignment, unsigned  SectionID, llvm::StringRef  SectionName, bool  IsReadOnly  )

override

Allocate space for data, and add it to the m_spaceBlocks map.

Parameters

[in]	Size	The size of the area.
[in]	Alignment	The required alignment of the area.
[in]	SectionID	A unique identifier for the section.
[in]	IsReadOnly	Flag indicating the section is read-only.

Returns
