bootstrap: include code cache in the embedded snapshot #43023
Conversation
Also added comments for the members of SnapshotData and renamed blob to v8_snapshot_blob_data for clarity.
Since V8 code cache encodes indices to the read-only space it is safer to make sure that the code cache is generated in the same heap used to generate the embdded snapshot. This patch merges the code cache builder into the snapshot builder and makes the code cache part of node::SnapshotData that is deserialized into the native module loader during bootstrap.

@joyeecheung this does not land cleanly in v16.x. Do you mind opening a backport PR to v16.x-staging? Thank you. |
