Value references¶

A value reference is a wrapper around an LLVM value for you to inspect. You cannot create a value reference yourself. You get them from methods of the ModuleRef and ValueRef classes.

Enumerations¶

class llvmlite.binding.Linkage¶

The linkage types allowed for global values are:

external¶
available_externally¶
linkonce_any¶
linkonce_odr¶
linkonce_odr_autohide¶
weak_any¶
weak_odr¶
appending¶
internal¶
private¶
dllimport¶
dllexport¶
external_weak¶
ghost¶
common¶
linker_private¶
linker_private_weak¶

class llvmlite.binding.Visibility¶

The visibility styles allowed for global values are:

default¶
hidden¶
protected¶

class llvmlite.binding.StorageClass¶

The storage classes allowed for global values are:

default¶
dllimport¶
dllexport¶

The ValueRef class¶

class llvmlite.binding.ValueRef¶

A wrapper around an LLVM value. The attributes available are:

is_declaration¶
- True—The global value is a mere declaration.
- False—The global value is defined in the given module.
linkage¶

The linkage type—a Linkage instance—for this value. This attribute can be set.
module¶

The module—a ModuleRef instance—that this value is defined in.
function¶

The function—a ValueRef instance—that this value is defined in.
block¶

The basic block—a ValueRef instance—that this value is defined in.
instruction¶

The instruction—a ValueRef instance—that this value is defined in.
name¶

This value’s name, as a string. This attribute can be set.
type¶

This value’s LLVM type as TypeRef object.
storage_class¶

The storage class—a StorageClass instance—for this value. This attribute can be set.
visibility¶

The visibility style—a Visibility instance—for this value. This attribute can be set.
blocks¶

An iterator over the basic blocks in this function. Each block is a ValueRef instance.
arguments¶

An iterator over the arguments of this function. Each argument is a ValueRef instance.
instructions¶

An iterator over the instructions in this basic block. Each instruction is a ValueRef instance.
operands¶

An iterator over the operands in this instruction. Each operand is a ValueRef instance.
opcode¶

The instruction’s opcode, as a string.
attributes¶

An iterator over the attributes in this value. Each attribute is a bytes instance. Values that have attributes are: function, argument (and others for which attributes support has not been implemented)
is_global¶

The value is a global variable.
is_function¶

The value is a function.
is_argument¶

The value is a function’s argument.
is_block¶

The value is a function’s basic block.
is_instruction¶

The value is a basic block’s instruction.
is_operand¶

The value is a instruction’s operand.
