current status: writing a proposal to radically simplify a thing with recursive template metaprogramming that requires C++11 or later

*mad scientist laugh* IT WORKS i can determine sizeof of things portably while cross compiling w/o running any codepic.twitter.com/QXZXqHneFV
@whitequark Why is this hard?
#define D(x) '0'+(x)/10, '0'+(x%10)
char foo[]={'V','A','L',D(sizeof(int)),0};
$ strings a.o | grep VAL
VAL04

@whitequark Misplaced a safety-paren while compressing for Twitter, but you get the idea :) - Show replies

@marcan42@whitequark This requires poking at binary formats. Instead you can do it relying on$CXX to exit with success/fail & bin search. -
@marcan42@whitequark It's also possible to produce an error message from the compiler containing the desired value. - Show replies
