From cda5f94e88b45c9209599bac15fc44add5a59f60 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sat, 27 Jan 2024 22:28:11 +0900 Subject: modpost: avoid using the alias attribute Aiden Leong reported modpost fails to build on macOS since commit 16a473f60edc ("modpost: inform compilers that fatal() never returns"): scripts/mod/modpost.c:93:21: error: aliases are not supported on darwin Nathan's research indicates that Darwin seems to support weak aliases at least [1]. Although the situation might be improved in future Clang versions, we can achieve a similar outcome without relying on it. This commit makes fatal() a macro of error() + exit(1) in modpost.h, as compilers recognize that exit() never returns.
