X86: repair export compatibility with MinGW/cygwin Both MinGW and cygwin (i686) construct export directives without the global leader prefix. This is mostly due to the fact that they use GNU ld which does not correctly handle the export directive. This apparently has been been broken for a while. However, this was recently reported as being broken by mingwandroid and diorcety of the msys2 project. Remove the global leader prefix if targeting MinGW or cygwin, otherwise, retain the global leader prefix. Add an explicit test for cygwin's behaviour of export directives. llvm-svn: 207926

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

Decouple dllexport/dllimport from linkage Representing dllexport/dllimport as distinct linkage types prevents using these attributes on templates and inline functions. Instead of introducing further mixed linkage types to include linkonce and weak ODR, the old import/export linkage types are replaced with a new separate visibility-like specifier: define available_externally dllimport void @f() {} @Var = dllexport global i32 1, align 4 Linkage for dllexported globals and functions is now equal to their linkage without dllexport. Imported globals and functions must be either declarations with external linkage, or definitions with AvailableExternallyLinkage. llvm-svn: 199218

Fix case confusion. The test case was defining and using a function 'notExported()', but the FileCheck checks were checking for the name 'not_exported'. This changes the test to use 'notExported' across the board. Also, the test defined a function 'not_defined()', but doesn't have any checks related to it. For consistency, this name is changed to 'notDefined'. A later commit will add checks for 'notDefined'. Patch by Warren Ristow! llvm-svn: 264984
