2011-02-18 | Fix efficiency bug for major (50% performance improvement! | Joshua Haberman | |
There was a bug with string referencing that prevented strings from being recycled as often as they ought to be. | |||
2011-02-17 | Return updated buf as second return value, to free up a reg. | Joshua Haberman | |
2011-02-17 | First version of an assembly language decoder. | Joshua Haberman | |
It is slower than the C decoder for now because it falls off the fast path too often. But it can successfully decode varints, fixed32 and fixed64. | |||
2011-02-17 | Split inttable into a hash part and an array part. | Joshua Haberman | |
upb_inttable() now supports a "compact" operation that will decide on an array size and put all entries with small enough keys into the array part for faster lookup. Also exposed the upb_itof_ent structure and put a few useful values there, so they are one fewer pointer chase away. | |||
2011-02-17 | Track buffer end instead of buffer length, for a small perf improvement. | Joshua Haberman | |
2011-02-15 | Remove upb_dstate and specialize upb_decode_fixed for perf improvement. | Joshua Haberman | |
The compiler wasn't keeping upb_dstate in memory anyway (which was the original goal). This simplifies the decoder. upb_decode_fixed was intended to minimize the number of branches, but since it was calling out to memcpy as a function, this turned out to be a pessimization. Performance is encouraging: plain32.parsestream_googlemessage1.upb_table: 254 -> 242 (-4.72) plain32.parsestream_googlemessage2.upb_table: 357 -> 400 (12.04) plain32.parsetostruct_googlemessage1.upb_table_byref: 143 -> 144 (0.70) plain32.parsetostruct_googlemessage1.upb_table_byval: 122 -> 118 (-3.28) plain32.parsetostruct_googlemessage2.upb_table_byref: 189 -> 200 (5.82) plain32.parsetostruct_googlemessage2.upb_table_byval: 198 -> 200 (1.01) omitfp32.parsestream_googlemessage1.upb_table: 267 -> 265 (-0.75) omitfp32.parsestream_googlemessage2.upb_table: 377 -> 465 (23.34) omitfp32.parsetostruct_googlemessage1.upb_table_byref: 140 -> 151 (7.86) omitfp32.parsetostruct_googlemessage1.upb_table_byval: 131 -> 131 (0.00) omitfp32.parsetostruct_googlemessage2.upb_table_byref: 204 -> 214 (4.90) omitfp32.parsetostruct_googlemessage2.upb_table_byval: 200 -> 206 (3.00) plain.parsestream_googlemessage1.upb_table: 313 -> 317 (1.28) plain.parsestream_googlemessage2.upb_table: 476 -> 541 (13.66) plain.parsetostruct_googlemessage1.upb_table_byref: 189 -> 189 (0.00) plain.parsetostruct_googlemessage1.upb_table_byval: 165 -> 165 (0.00) plain.parsetostruct_googlemessage2.upb_table_byref: 263 -> 270 (2.66) plain.parsetostruct_googlemessage2.upb_table_byval: 248 -> 255 (2.82) omitfp.parsestream_googlemessage1.upb_table: 306 -> 305 (-0.33) omitfp.parsestream_googlemessage2.upb_table: 471 -> 531 (12.74) omitfp.parsetostruct_googlemessage1.upb_table_byref: 189 -> 190 (0.53) omitfp.parsetostruct_googlemessage1.upb_table_byval: 166 -> 172 (3.61) omitfp.parsetostruct_googlemessage2.upb_table_byref: 258 -> 270 (4.65) omitfp.parsetostruct_googlemessage2.upb_table_byval: 248 -> 265 (6.85) | |||
2011-02-15 | Make -DUPB_THREAD_UNSAFE the default for now. | Joshua Haberman | |
2011-02-14 | Recover bad performance of 0-keyed tables. | Joshua Haberman | |
We do this by special-casing the (unusual) zero case and only bother checking the is_empty bit in the zero case. | |||
2011-02-14 | Update to latest descriptor.proto. | Joshua Haberman | |
2011-02-14 | More completely fixed the 0-key thing. | Joshua Haberman | |
Unfortunately this degrades hash table lookup performance by about 8%, which affects the streaming benchmark for googlemessage1 by about 5%. We could get this back at the cost of some memory, but it would be nice to avoid that. | |||
2011-02-14 | Remove the restriction that 0 cannot be a table key. | Joshua Haberman | |
