Status: RESOLVED FIXED

(Firefox Build System :: General, enhancement)

We're currently using sccache for clang-cl builds, but it doesn't actually work right. For example, in this build:
https://treeherder.mozilla.org/#/jobs?repo=mozilla-inbound&selectedJob=90128456

14:24:44     INFO -  Compile requests 3133
14:24:44     INFO -  Compile requests executed 19
14:24:44     INFO -  Cache hits 0
14:24:44     INFO -  Cache misses  19
<...>
14:24:44     INFO -  Unsupported compiler calls 3110


I filed an sccache issue about supporting clang-cl properly, so if we get that working we can certainly re-enable it:

sccache doesn't actually support clang-cl currently, so we're just making
our clang-cl builds slower by enabling it. Also, I'm trying to update to
a newer version of sccache and something broke running sccache+clang-cl
entirely so my try builds are busted, so disabling it entirely until
we actually support this configuration seems sensible.
