Struct SimpleJITBuilder 

pub struct SimpleJITBuilder { /* private fields */ }

A builder for SimpleJITModule.

Implementations

impl SimpleJITBuilder

pub fn new(libcall_names: Box<dyn Fn(LibCall) -> String>) -> Self

Create a new SimpleJITBuilder.

The libcall_names function provides a way to translate cranelift_codegen’s ir::LibCall enum to symbols. LibCalls are inserted in the IR as part of the legalization for certain floating point instructions, and for stack probes. If you don’t know what to use for this argument, use cranelift_module::default_libcall_names().

pub fn with_isa( isa: Box<dyn TargetIsa>, libcall_names: Box<dyn Fn(LibCall) -> String>, ) -> Self

Create a new SimpleJITBuilder with an arbitrary target. This is mainly useful for testing.

SimpleJIT requires a TargetIsa configured for non-PIC.

To create a SimpleJITBuilder for native use, use the new constructor instead.

pub fn symbol<K>(&mut self, name: K, ptr: *const u8) -> &Self

where K: Into<String>,

Define a symbol in the internal symbol table.

The JIT will use the symbol table to resolve names that are declared, but not defined, in the module being compiled. A common example is external functions. With this method, functions and data can be exposed to the code being compiled which are defined by the host.

If a symbol is defined more than once, the most recent definition will be retained.

If the JIT fails to find a symbol in its internal table, it will fall back to a platform-specific search (this typically involves searching the current process for public symbols, followed by searching the platform’s C runtime).

pub fn symbols<It, K>(&mut self, symbols: It) -> &Self

where It: IntoIterator<Item = (K, *const u8)>, K: Into<String>,

Define multiple symbols in the internal symbol table.

Using this is equivalent to calling symbol on each element.
