// Testcase for an IRGen crash with function pointers in static globals and multi-threaded compilation.
|
|
|
|
// First test: check if the compilation succeeds and the code is correct.
|
|
|
|
// RUN: %empty-directory(%t)
|
|
// RUN: %target-build-swift -O -module-name=Test %s -o %t/a.out
|
|
// RUN: %target-codesign %t/a.out
|
|
// RUN: %target-run %t/a.out | %FileCheck %s -check-prefix=CHECK-OUTPUT
|
|
|
|
// Second test (bonus): check if the optimization is done: statically initialize a global with a C-function pointer
|
|
|
|
// RUN: %target-build-swift -O -module-name=Test %s -emit-sil | %FileCheck %s -check-prefix=CHECK-SIL
|
