Josh Haberman	7d3e2bd2c4	Sync with 8 months of Google-internal development. Many things have changed and been simplified. The memory-management story for upb_def and upb_handlers is much more robust; upb_def and upb_handlers should be fairly stable interfaces now. There is still much work to do for the runtime component (upb_sink).	12 years ago
Josh Haberman	c16c978193	Updated DynASM from upstream (Lua 5.2 support).	13 years ago
Joshua Haberman	9eb4d695c4	First rough version of the JIT. It can successfully parse SpeedMessage1. Preliminary results: 750MB/s on Core2 2.4GHz. This number is 2.5x proto2. This isn't apples-to-apples, because proto2 is parsing to a struct and we are just doing stream parsing, but for apps that are currently using proto2, this is the improvement they would see if they could move to stream-based processing. Unfortunately perf-regression-test.py is broken, and I'm not 100% sure why. It would be nice to fix it first (to ensure that there are no performance regressions for the table-based decoder) but I'm really impatient to get the JIT checked in.	14 years ago

Sync with 8 months of Google-internal development.

Many things have changed and been simplified.
The memory-management story for upb_def and upb_handlers
is much more robust; upb_def and upb_handlers should be
fairly stable interfaces now.  There is still much work
to do for the runtime component (upb_sink).

First rough version of the JIT.

It can successfully parse SpeedMessage1.
Preliminary results: 750MB/s on Core2 2.4GHz.
This number is 2.5x proto2.
This isn't apples-to-apples, because
proto2 is parsing to a struct and we are
just doing stream parsing, but for apps
that are currently using proto2, this is the
improvement they would see if they could
move to stream-based processing.

Unfortunately perf-regression-test.py is
broken, and I'm not 100% sure why.  It would
be nice to fix it first (to ensure that
there are no performance regressions for
the table-based decoder) but I'm really
impatient to get the JIT checked in.
