Serge Pavlov	947719bed1	Process attributes 'ifunc' and 'alias' when checking for redefinition ... These attributes effectively turn a non-defining declaration into a definition, so the case when the declaration already has a body must be diagnosed properly. Differential Revision: https://reviews.llvm.org/D30032 llvm-svn: 295541	2017-02-18 06:04:15 +00:00
David Majnemer	290d347471	Revert "Sema: err_after_alias is unreachable, remove it" ... This reverts commit r226626. err_after_alias is, in fact, reachable. llvm-svn: 226633	2015-01-21 01:30:40 +00:00
David Majnemer	1efd55ff21	Sema: err_after_alias is unreachable, remove it ... Examples this would have catched are now handled by the attribute verification code. llvm-svn: 226626	2015-01-21 00:52:17 +00:00
David Majnemer	6b90356ab4	Add back a check removed in r226436 ... It shouldn't have been removed, the code which replaced it didn't cover this case. llvm-svn: 226442	2015-01-19 10:21:22 +00:00
David Majnemer	2dc8146643	Sema: Variable definitions cannot be __attribute__((alias)) ... Things that are OK: extern int var1 __attribute((alias("v1"))); static int var2 __attribute((alias("v2"))); Things that are not OK: int var3 __attribute((alias("v3"))); extern int var4 __attribute((alias("v4"))) = 4; We choose to accpet: struct S { static int var5 __attribute((alias("v5"))); }; This code causes assertion failues in GCC 4.8 and ICC 13.0.1, we have no reason to reject it. This partially fixes PR22217. llvm-svn: 226436	2015-01-19 09:00:28 +00:00
Rafael Espindola	d53ffa0a70	Treat aliases as definitions. ... This fixes pr17639. Before this patch clang would consider void foo(void) __attribute((alias("__foo"))); a declaration. It now correctly handles it as a definition. Initial patch by Alp Toker. I added support for variables. llvm-svn: 193200	2013-10-22 21:39:03 +00:00
