+Parsing:
+
+When # is encountered
+ Deal with ## case (escaped)
+ Read length modifier
+ gcc-like
+ trace specific : 1, 2, 4, 8, n, b
+ in both cases, save the output type size (1, 2, 4, 8).
+ Read conversion specifier
+ save the output type size if no length modifier is involved (1, 2, 4, 8).
+ save the signedness.
+
+(vsnprintf-like part)
+When % is encountered
+ Deal with %% case (escaped)
+ (deal with field width, precision. Skip them.)
+ Read length modifier
+ if output type size is 0, set it to the gcc type size.
+ Read conversion specifier
+ if output type size is 0, set it to the gcc type size if no length modifier
+ is involved.
+ Perform trace write with conversion.
+ Reset output type size to 0
