Bug ID: 50767
Summary: Function __attribute__((nodebug)) inconsistency causes
crash
Product: clang
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: Frontend
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected],

When the nodebug attribute of a function appears only at its definition (so an
earlier declaration of the function did not have the attribute) this crashes
clang.
Example:
void foo();
void use() { foo(); }
__attribute__((nodebug)) void foo() { }
Command:
clang -c -g1 -O nodbg.cpp
Godbolt link: https://godbolt.org/z/nTYKW66Gf
On an assertion build, I think the error message is "function definition may
only have a distinct !dbg attachment" then "fatal error: error in backend:
Broken module found, compilation aborted!"
If needed that you annotate earlier declarations with nodebug, clang should
enforce this?
