jit
Just-in-time compilation, performance optimization.
Load with: use jit
Quick example
use jit
result = jitco("value", 10, "value")
prn(result)Functions
JIT compiler
jitne()
Creates a new instance.
jitco(jit, func, args_types)
Connects. Takes jit, func, args_types.
jitru(jit, func, args)
Runs. Takes jit, func, args.
Tracing JIT
jtrne()
Creates a new instance.
jtrre(tracer, func_id, bytecode_pos, stack_snapshot)
Performs the operation. Takes tracer, func_id, bytecode_pos, stack_snapshot.
jtrad(trace, opcode, operands)
Adds an item. Takes trace, opcode, operands.
jtrgu(trace, condition, snapshot)
Performs the operation. Takes trace, condition, snapshot.
jtrcm(trace)
Performs the operation. Takes trace.
Type specialization
jitsp(types)
Performs the operation. Takes types.
jitun(value)
Performs the operation. Takes value.
Optimization passes
jitop(ast, max_depth)
Opens a connection or resource. Takes ast, max_depth.
jitop1(ast)
Performs the operation. Takes ast.
jitop2(ast)
Performs the operation. Takes ast.
jitop3(ast)
Performs the operation. Takes ast.
jitop4(ast, factor)
Performs the operation. Takes ast, factor.
jitop5(ast)
Performs the operation. Takes ast.
Profiling
jtpst()
Sets a value or starts a process.
jtpst1()
Performs the operation.
jtprp()
Performs the operation.
Adaptive optimization
jtane()
Creates a new instance.
jtaca(adaptive, args)
Performs the operation. Takes adaptive, args.
Bytecode -> Native
jitbc(bytecode, target_arch)
Performs the operation. Takes bytecode, target_arch.
Deoptimization
jtdeo(jit_frame, reason)
Performs the operation. Takes jit_frame, reason.
OSR (On-Stack Replacement)
jtosr(func, bytecode_pos, locals)
Performs the operation. Takes func, bytecode_pos, locals.
Inline caching
jticn()
Performs the operation.
jticl(ic, key)
Closes or clears. Takes ic, key.
jtics(ic, key, value)
Performs the operation. Takes ic, key, value.
JIT statistics
jitst(jit)
Sets a value or starts a process. Takes jit.
Notes
- JIT compilation helpers - emit machine code, manage executable memory.
