Improve CHECK-NOT robustness of dllexport tests This changes some dllexport tests, to verify that some symbols that should not be exported are not, in a way that improves the robustness of CHECK-SAME interaction with CHECK-NOT. We plan to enable dllimport/dllexport support for the PS4, and these changes are for points we noticed in our internal testing. Patch by Warren Ristow! llvm-svn: 265106

Prevent alias from pointing to weak aliases. This adds back r204781. Original message: Aliases are just another name for a position in a file. As such, the regular symbol resolutions are not applied. For example, given define void @my_func() { ret void } @my_alias = alias weak void ()* @my_func @my_alias2 = alias void ()* @my_alias We produce without this patch: .weak my_alias my_alias = my_func .globl my_alias2 my_alias2 = my_alias That is, in the resulting ELF file my_alias, my_func and my_alias are just 3 names pointing to offset 0 of .text. That is *not* the semantics of IR linking. For example, linking in a @my_alias = alias void ()* @other_func would require the strong my_alias to override the weak one and my_alias2 would end up pointing to other_func. There is no way to represent that with aliases being just another name, so the best solution seems to be to just disallow it, converting a miscompile into an error. llvm-svn: 204934

Emit data or code export directives based on the type. Currently we look at the Aliasee to decide what type of export directive to use. It seems better to use the type of the alias directly. This is similar to how we handle the alias having the same address but other attributes (linkage, visibility) from the aliasee. With this patch it is now possible to do things like target datalayout = "e-m:e-i64:64-f80:128-n8:16:32:64-S128" target triple = "x86_64-pc-windows-msvc" @foo = global [6 x i8] c"\B8*\00\00\00\C3", section ".text", align 16 @f = dllexport alias i32 (), [6 x i8]* @foo !llvm.module.flags = !{!0} !0 = metadata !{i32 6, metadata !"Linker Options", metadata !1} !1 = metadata !{metadata !2, metadata !3} !2 = metadata !{metadata !"/DEFAULTLIB:libcmt.lib"} !3 = metadata !{metadata !"/DEFAULTLIB:oldnames.lib"} llvm-svn: 209600
