Split GeneratedSerializersShared.mm to improve build parallelism.
https://bugs.webkit.org/show_bug.cgi?id=316688
rdar://179142771
Reviewed by Elliott Williams.
One a decent M2 Ultra build, GeneratedSerializersShared.mm is taking roughly 69
seconds to
compile. This is happening at the tail end of the WebKit step of the build, and
is blocking
linking and further build steps from starting. This represents ~59 seconds of
wasted time
since only a single core is working, and other tasks are blocked.
We can improve matters by splitting this single large compilation unit into
smaller pieces
that can build in parallel.
This change drops that 69 second long pole to 53.5 seconds, and allows it to
run in
parallel with other steps reducing the overall build time by about 70 seconds.
