Nikita Popov 520d387350 [MC] Use subclass data for MCExpr to reduce memory usage ... MCExpr has a bunch of free space that is currently going to waste. Repurpose it as 24 bits of subclass data, which is enough to reduce the size of all subclasses by 8 bytes. This gives us some respectable savings for debuginfo builds. Here are the max-rss reductions for the fat LTO link step: kc.link 238MiB 231MiB (-2.82%) sqlite3.link 258MiB 250MiB (-3.27%) consumer-typeset.link 152MiB 148MiB (-2.51%) bullet.link 197MiB 192MiB (-2.30%) tramp3d-v4.link 578MiB 567MiB (-1.92%) pairlocalalign.link 92MiB 90MiB (-1.98%) clamscan.link 230MiB 223MiB (-2.81%) lencod.link 242MiB 235MiB (-2.67%) SPASS.link 235MiB 230MiB (-2.23%) 7zip-benchmark.link 450MiB 435MiB (-3.25%) Differential Revision: https://reviews.llvm.org/D77939		2020-04-15 20:02:11 +02:00
