Change test to use -S so it works when an external assembler is used that is not present in the testing environment. 2020-02-28 08:51:57 +08:00			`// RUN: %clang -fopenmp -O -g -x c %s -S -disable-output -o %t`
[OpenMP][Opt] Combine `struct ident_t` during deduplication If we deduplicate OpenMP runtime calls we have multiple `ident_t` that represent information like source location. So far, we simply kept the one used by the replacement call. However, as exposed by PR44893, that can cause problems if we have stack allocated `ident_t` objects. While we need to revisit the use of these as well, it is clear that we eventually want to merge source location information in some way. With this patch we add the infrastructure to do so but without doing the actual merge. Instead we pick a global `ident_t` from the replaced calls, if possible, or create a new one with an unknown location instead.
