Rui Ueyama 69c778c084 Implement almost-zero-cost --trace-symbol. ... --trace-symbol is a command line option to watch a symbol. Previosly, we looked up a hash table for a new symbol if the option is given. Any code that looks up a hash table for each symbol is expensive because the linker handles a lot of symbols. In our design, we look up a hash table strictly only once for a symbol, so --trace-symbol was an exception. This patch improves efficiency of the option by merging the hash table into the symbol table. Instead of looking up a separate hash table with a string, this patch sets `Traced` flag to symbols specified by --trace-symbol. So, if you insert a symbol and get a symbol with `Traced` flag on, you know that you need to print out a log message for the symbol. This is nearly zero cost. llvm-svn: 275716		2016-07-17 17:50:09 +00:00
