2022-09-01compiler_wrapper: redisable unused-but-set-varRyan Beltran
This CL add the Wno-unused-but-set-variable flag back into the compiler wrapper. It was previously removed, but there are still occurances of the warning and so we were never able to bundle that change into chromoumos-overlay/llvm. An attempt to revert the original CL failed due to a merge conflict.

2020-07-14compiler_wrapper: remove -grecord-gcc-switchesBob Haarman
-grecord-gcc-switches causes the compiler and compiler flags to be stored in the produced debug information. This causes Goma builds to be non-deterministic, because the compiler path differs depending on whether the compiler was run locally or on Goma. This, in turn, causes cache pollution and needless work. Since we are not in fact using the information stored by -grecord-gcc-switches, this change disables it. We can re-enable it when we want to start using the information, provided we come up with another way to avoid the issues described earlier.
