https://issues.dlang.org/show_bug.cgi?id=22096 Issue ID: 22096 Summary: Can not get global struct member addresses at compile time Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: enhancement Priority: P1 Component: dmd Assignee: nobody@puremagic.com Reporter: dbugs@yhzar.kellerspeicher.ch Hi! This report is based on the forum thread: https://forum.dlang.org/thread/cjbjcuzsefvjryrjlflf@forum.dlang.org I'm currently investigating why I can not take the address of a static struct-element at compile time. struct Foo{ int bar; } __gshared Foo foo; void *foo_ptr = &foo; // Works void *bar_ptr = &foo.bar; // Error: static variable `foo` cannot be read at compile time The D-Compiler passes the relocation of *foo_ptr down to the linker, but relocations plus an offset seem to not work. If I'd have to guess I'd say that this is a side-effect of all member accesses possibly being function calls. -- |
