Interface for driving the creation of jitdump files

Implementations§

source§

impl JitDumpAgent

source

pub fn new() -> Result<Self>

Intialize a JitDumpAgent and write out the header.

source§

impl JitDumpAgent

source

pub fn dump_from_debug_image( &self, jitdump_file: &mut JitDumpFile, dbg_image: &[u8], module_name: &str, addr: *const u8, len: usize, pid: u32, tid: u32, ) -> Result<()>

Attempts to dump debuginfo data structures, adding method and line level for the jitted function.

Trait Implementations§

source§

impl ProfilingAgent for JitDumpAgent

source§

fn module_load(&self, module: &CompiledModule, dbg_image: Option<&[u8]>)

Sent when a method is compiled and loaded into memory by the VM.

source§

fn load_single_trampoline( &self, name: &str, addr: *const u8, size: usize, pid: u32, tid: u32, )

Notify the profiler about a single dynamically-generated trampoline (for host function) that is being loaded now.`
