Unbreak bleeding_edge by getting the Parser to work with a CompilationInfo instead of a Handle<Script> and a Zone. This should have been fixed in the initial patch itself but escaped my attention.

One Zone per CompilationInfo. · 9e4fbb45

sanjoy@chromium.org authored Jun 20, 2012

The CompilationInfo record now saves a Zone, and the compiler pipeline
allocates memory from the Zone in the CompilationInfo.  Before
compiling a function, we create a Zone on the stack and save a pointer
to that Zone to the CompilationInfo; which then gets picked up and
allocated from.

Snapshots: Add --extra-code flag to mksnapshot which lets you specify a file · 458e87fd

with more JS code that is loaded into the VM before writing the snapshot. Get
rid of the hard coded limit on the partial snapshot cache size. This change
disables most of the serializer tests for the snapshot build of the VM: It's
getting too complicated to support both booting from a snapshot and then
creating a new snapshot from the same VM or loading more code with another
snapshot in the same VM.

Enable lazy compilation for non-trivial outer contexts. · a760b82c

mstarzinger@chromium.org authored Jun 19, 2012

This changes the compiler to be more aggressive about lazy compilation
of closures with non-trivial outer context. Compilation can only be
triggered with a valid outer context now. One exception is the debugger,
which can request compilation of arbitrary shared code, but it ensures
to trigger compilation only at points where no context is needed.

This relands r11782, r11783, r11790 and a minor fix.

Each SharedFunctionInfo gets an optimized code map to store
