Issue ID: 23965
Summary: [REG2.101.0] Appending deprecated structs in
deprecated function causes deprecation message
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Keywords: rejects-valid
Severity: regression
Priority: P3
Component: dmd
Assignee: [email protected]
Reporter: [email protected]
Generally, deprecated code can use other deprecated code without additional
messages. This allows to bulk-deprecate interdependent code in a library,
making it possible to allow the library to compile with no deprecation
messages, but only causing them if something (non-deprecated) accesses the
deprecated declarations.
However, the following case has regressed in 2.101:
//// test.d ///
deprecated:
struct S {}
void fun()
{
S[] arr;
arr ~= S();
}
///////////////
Before it compiled with no errors or messages.
Now, with -de, it fails with:
/path/to/dmd.linux/dmd2/linux/bin64/../../src/druntime/import/core/internal/array/appending.d(#):
Deprecation: struct `test.S` is deprecated
test.d(8): instantiated from here: `_d_arrayappendcTXImpl!(S[], S)`
/path/to/dmd.linux/dmd2/linux/bin64/../../src/druntime/import/core/internal/array/utils.d(#):
Deprecation: struct `test.S` is deprecated
/path/to/dmd.linux/dmd2/linux/bin64/../../src/druntime/import/core/internal/array/appending.d(#):
instantiated from here: `_d_HookTraceImpl!(S[], _d_arrayappendcTX,
"Cannot append to array if compiling without support for runtime type
information!")`
test.d(8): instantiated from here: `_d_arrayappendcTXImpl!(S[], S)`
Introduced in https://github.com/dlang/dmd/pull/13495.
