This is the first step of turning the v8.h file into a normal header instead of an include-the-world header. The new rule is that no other header files are allowed to include v8.h, which is enforced by DEPS. Also the number of includes inside the v8.h file has been drastically reduced. Basically the last missing piece is the inclusion of the big objects-inl.h file. This in turn makes many headers follow the IWYU principle.

// GDB has two ways of interacting with JIT code. With the "JIT compilation
|
|
// interface", V8 can tell GDB when it emits JIT code. Unfortunately to do so,
|
|
// it has to create platform-native object files, possibly with platform-native
|
|
// debugging information. Currently only ELF and Mach-O are supported, which
|
|
// limits this interface to Linux and Mac OS. This JIT compilation interface
|
|
// was introduced in GDB 7.0. V8 support can be enabled with the --gdbjit flag.
|
|
//
|
|
// The other way that GDB can know about V8 code is via the "custom JIT reader"
|
|
// interface, in which a GDB extension parses V8's private data to determine the
|
|
// function, file, and line of a JIT frame, and how to unwind those frames.
|
|
// This interface was introduced in GDB 7.6. This interface still relies on V8
|
|
// to register its code via the JIT compilation interface, but doesn't require
|
|
// that V8 create ELF images. Support will be added for this interface in the
|
|
// future.
