annotate lwasm/symbol.c @ 472:e97f9a302c6a

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add emuext pragma and associated instructions. This provides two emulator specific instructions ("log" and "debug") enabled by the "emuext" pragma. This is from a patch provided by tim Lindner <tlindner@macmess.org>. From Tim's submission: ---- I stole the whole patch from Erik Gavriluk. I hope he doesn't mind. :) The two instructions are "debug" and "log". They are enabled with pragmas. I also added them to the manual. Hopefully all is well. ---- Said Erik Gavriluk <erik@bombfactory.com> in response: ...happy to see them picked up in mainline (if you choose to do so)....
