Hi Michael, On Windows I get this error for 113_btdll new test:

It also doesn't deal with scopes, i.e. represents this incorrectly: int foo (void) { int i = 1; float f; if (i) { float i = 1.0; f = i; } return i + f; } It's still useful, of course, also with the limitation. Some time ago I approached the debug problem from that angle first before dealing with types, see attached patch (which makes all variable be int). But I didn't like the outcome in that it uses a new data structure for the scopes and the associated book keeping. The difficulty with stabs is that the variables for a scope need to be emitted directly _before_ the scope-open stab, which really goes against the structure of TCCs parser, as the open/close stabs still need to form a correct nesting, so there's no natural place to emit the variable stabs :-/ Ciao, Michael. >> >> So: >> int main(int argc, char *argv[]) >> >> is supported. >> >> Other things like structs/unions/enums/bitfields are all translated >> to void. >> This should probably change in the future. >> >> I also generate a new type whenever I see a pointer or array. >> This creates a lot of types but gdb seems happy with it. >> If I compile tcc with bounds-checking I see 1473 types. >> In the future types should be optimized. >> >> Can I apply this patch? _______________________________________________ Tinycc-devel mailing list Tinycc-devel@nongnu.org https://lists.nongnu.org/mailman/listinfo/tinycc-devel
