Struct dynasmrt::Assembler[][src]

pub struct Assembler<R: Relocation> { /* fields omitted */ }
Expand description

A full assembler implementation. Supports labels, all types of relocations, incremental compilation and multithreaded execution with simultaneous compiltion. Its implementation guarantees no memory is executable and writable at the same time.

Implementations

Create a new, empty assembler, with initial allocation size page_size.

Create a new dynamic label ID

Use an UncommittedModifier to alter uncommitted code. This does not allow the user to change labels/relocations.

Use a Modifier to alter committed code directly. While this is happening no code can be executed as the relevant pages are remapped as writable. This API supports defining new labels/relocations, and overwriting previously defined relocations.

Commit code, flushing the temporary internal assembling buffer to the mapped executable memory. This makes assembled code available for execution.

Finalize this assembler, returning the internal executablebuffer if no Executor instances exist. This panics if any uncommitted changes caused errors near the end. To handle these, call commit() explicitly beforehand.

Create an executor which can be used to execute code while still assembling code

Provides access to the assemblers internal labels registry

Provides mutable access to the assemblers internal labels registry

This function is called in when a runtime error has to be generated. It panics.

The relocation info type this assembler uses.

Record the definition of a local label

Record the definition of a global label

Record the definition of a dynamic label

Equivalent of global_reloc, but takes a non-encoded relocation

Equivalent of dynamic_reloc, but takes a non-encoded relocation

Equivalent of forward_reloc, but takes a non-encoded relocation

Equivalent of backward_reloc, but takes a non-encoded relocation

Equivalent of bare_reloc, but takes a non-encoded relocation

Record a relocation spot for a forward reference to a local label

Record a relocation spot for a backward reference to a local label

Record a relocation spot for a reference to a global label

Record a relocation spot for a reference to a dynamic label

Record a relocation spot to an arbitrary target.
