You are completely right Jonathan. My Apologies. WPP is a tool I use in my work field on an every-day basis, so I thought it was known.
Here is the Wikipedia page on WPP: http://en.wikipedia.org/wiki/Windows_software_trace_preprocessor In short, WPP allows to put traces and logs in your C/C++ products and send to customers, without including sensitive tracing/logging strings in your binary. What WPP does, is it runs during pre-compilation, and replaces the string in each call to a trace macro, with an obfuscated string. So: DoTrace("program started %d %s beginning", num, str); is Replaced to: DoTrace("897192873 __LINE__ __FILE__ %d %s", num, str); And puts the original string in the Debug's .pdb file, with the debug symbols. Later, the user can use a software like EtwDataViewer (see first google result for screenshot) to "Reverse" the WPP traces, and recover the original traces of the program. I hope my explanation is clear. So again: 1. Can you think of a way to achieve this with gcc? We used regular expressions until now to find the "DoTrace" and replace the strings, but needless to say its ugly. We also thought about implementing a gcc plugin, but I think a lot of people can benefit from it being embedded in gcc, instead of having to import an .so file to enjoy this feature. 2. Do you think its a good feature for gcc, and will you (the maintainers) be willing to merge it, after we'll implement it? Thanks again for your help, Shoham Peller On Sun, Apr 26, 2015 at 4:16 PM, Jonathan Wakely <jwakely....@gmail.com> wrote: > On 25 April 2015 at 23:23, Shoham Peller wrote: >> Hi Guys, >> >> It's been 4 days.
