Hi Folks,
We've been collecting some performance numbers, and I need help
understanding them in the context of antlr.
Any idea what these functions are (linux g++ compiler):
% function name
----- ------------------------------
19.50 read_encoded_value_with_base(u
18.74 read_uleb128(unsigned char con
9.85 __gxx_personality_v0
6.75 base_of_encoded_value(unsigned
4.23 execute_cfa_program
4.03 _Unwind_IteratePhdrCallback
Any information, especially on read_encoded_value_with_base, would be
great. I see a few hits on the web, but nothing substantial. Having
20% of our execution time go into something that we don't grok
concerns me a bit ;-)
