I wish to use extended precision in functions compiled by tcc during execution. Unfortunately, it appears that for any functions compiled by tcc, sizeof (double) == sizeof (long double) - and I haven't got the slightest clue whether it's intended, if it's a bug or if I'm missing some flags.
Specifications: tcc (latest version 2014-08-01 http://repo.or.cz/w/tinycc.git/shortlog ) compiled with msys mingw (using command: ./configure [--prefix installpath]) Test code ( http://pastebin.com/yiSDFfYU ) is compiled with gcc (codeblocks, 64bit, windows 7). *tcc-compiled code:* char my_program[] = "int GetLongDoubleSize(int n)\n" "{\n" " return sizeof(long double);\n" //returns 8 "}\n" "int GetDoubleSize(int n)\n" "{\n" " return sizeof(double);\n" //returns 8 "}\n"; *Output:* ----- tcc compiled 'char program': Long Double size: 8 Double size: 8 ----- gcc compiled functions: gcc Long Double size: 12 gcc Double size: 8
