CodeGen: correct handling of debug info generation for aliases 2022-08-16T21:27:05+00:00 Saleem Abdulrasool compnerd@compnerd.org 2022-08-16T21:22:27+00:00 585f62be1a438ca132aa443e556d102bc908a072 When aliasing a static array, the aliasee is going to be a GEP which points to the value. We should strip pointer casts before forming the reference. This was occluded by the use of opaque pointers. This problem has existed since the introduction of the debug info generation for aliases in b1ea0191a42074341847d767609f66a26b6d5a41. The test case would assert due to the invalid cast with or without `-no-opaque-pointers` at that revision. Fixes: #57179
