Bug 24314 – Linker flag `-L-dead_strip`strips `static this()` and `static ~this()`

// file: test.d // // Problem description: // // When using the additional linker flag `-L-dead_strip` // on macOS, executables produced by DMD strip // static constructors + destructors. // The program runs fine, but static init is silently removed. // // It does not happen with LDC - only with DMD on macOS (x64). // // The online compiler at run.dlang.org does not have the issue. // The compiler option for the online compiler is: `-L-strip-all` // // // [OK] output: // // Hi! // Hello D // Bye! // // [FAIL] output (static constructor/destructor not running): // // Hello D // // Results using DMD: // // [OK] dmd -run test.d // [OK] dmd -release -run test.d // [OK] dmd -debug -run test.d // // [FAIL] dmd -L-dead_strip -run test.d // [FAIL] dmd -L-dead_strip -release -run test.d // [FAIL] dmd -L-dead_strip -debug -run test.d // // Results using LDC: // // [OK] ldc2 --run test.d // [OK] ldc2 --release --run test.d // [OK] ldc2 --d-debug --run test.d // [OK] ldc2 --d --run test.d // // [OK] ldc2 -L-dead_strip --run test.d // [OK] ldc2 -L-dead_strip --release --run test.d // [OK] ldc2 -L-dead_strip --d-debug --run test.d // [OK] ldc2 -L-dead_strip --d --run test.d // import std.stdio : writeln; void main() => writeln(" Hello D"); static this() => writeln("Hi!"); static ~this() => writeln("Bye!");
