2020-11-26compiler_wrapper: move llvm-next options to clang optionsinglorion
The new Clang version has a number of new warnings which we disable. This CL makes those apply to llvm (current) as well as llvm-next.

2020-08-10compiler_wrapper: use crashArtifactsDir to apply clang optsGeorge Burgess IV
Since we now have crashArtifactsDir as a more abstract concept, it seems good to apply '-fcrash-diagnostics-dir=' based on that, rather than having it as an explicit clang flag.

2020-07-30compiler_wrapper: add -fexperimental-new-pass-managerJian Cai
LLVM is currently build with DENABLE_EXPERIMENTAL_NEW_PASS_MANAGER=ON on Chrome OS. This is however not reflected in clang crash diagnoses. Adding -fexperimental-new-pass-manager to help with reproducibility on 4c. BUG=chromium:1111103 TEST=CQ tests.

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.

2020-06-26compiler_wrapper: redirect clang crash dignosesJian Cai
Redirect all diagnoses of clang crashes to a dedicated directory using fcrash-diagnostics-dir so we can upload these files to the cloud. The flag was added to clangPostFlags to overwite redirection done on package level.

2020-03-13compiler_wrapper: Add "-fcommon" to clang invocationsManoj Gupta
Clang ToT has switched to "-fno-common" as default to match GCC 10 which breaks many packages. Upgrading to ToT versions of many packages does not fix the problem as packages upstream have not fixed them yet. Pass "-fcommon" in compiler wrapper to workaround this for now. This does not change the current clang behavior which defaults to "-fcommon" so this is a NFC.

This will gracefully handle cases where a warning enforced with -Werror got stricter in upstream. This change also needs updates to golden testdata. No additional tests added since this is covered by existing tests. Originally reviewed in https://android-review.googlesource.com/c/1244796.
