class StackLayout
Declaration
class StackLayout { /* full declaration omitted */ };Description
Compute the layout of an unsafe stack frame.
Declared at: llvm/lib/CodeGen/SafeStackLayout.h:24
Method Overview

- public void addObject(const llvm::Value * V, unsigned int Size, unsigned int Alignment, const StackColoring::LiveRange & Range)
- public void computeLayout()
- public unsigned int getFrameAlignment()
- public unsigned int getFrameSize()

Methods
¶StackLayout(unsigned int StackAlignment)
StackLayout(unsigned int StackAlignment)Declared at: llvm/lib/CodeGen/SafeStackLayout.h:54
Parameters
- unsigned int StackAlignment
¶void addObject(
const llvm::Value* V,
unsigned int Size,
unsigned int Alignment,
const StackColoring::LiveRange& Range)
void addObject(
const llvm::Value* V,
unsigned int Size,
unsigned int Alignment,
const StackColoring::LiveRange& Range)Description
Add an object to the stack frame. Value pointer is opaque and used as a handle to retrieve the object's offset in the frame later.
Declared at: llvm/lib/CodeGen/SafeStackLayout.h:58
Parameters
- const llvm::Value* V
- unsigned int Size
- unsigned int Alignment
- const StackColoring::LiveRange& Range
¶void computeLayout()
void computeLayout()Description
Run the layout computation for all previously added objects.
Declared at: llvm/lib/CodeGen/SafeStackLayout.h:62
¶unsigned int getFrameAlignment()
unsigned int getFrameAlignment()Description
Returns the alignment of the frame.
Declared at: llvm/lib/CodeGen/SafeStackLayout.h:74
¶unsigned int getFrameSize()
unsigned int getFrameSize()Description
Returns the size of the entire frame.
Declared at: llvm/lib/CodeGen/SafeStackLayout.h:71
¶unsigned int getObjectAlignment(
const llvm::Value* V)
unsigned int getObjectAlignment(
const llvm::Value* V)Description
Returns the alignment of the object
Declared at: llvm/lib/CodeGen/SafeStackLayout.h:68
Parameters
- const llvm::Value* V
¶unsigned int getObjectOffset(const llvm::Value* V)
unsigned int getObjectOffset(const llvm::Value* V)Description
Returns the offset to the object start in the stack frame.
Declared at: llvm/lib/CodeGen/SafeStackLayout.h:65
Parameters
- const llvm::Value* V
