Ayke van Laethem	152caa3b0a	compiler: do not create stack objects for functions that don't allocate ... This is a useful optimization for targets with the portable garbage collector. It isn't as big as you might guess but it does optimize functions inside the garbage collector itself (which obviously should not allocate). WebAssembly output in one test is about 1% smaller.	2019-07-08 00:02:28 +02:00
Ayke van Laethem	c66d979ba3	compiler: avoid some stack frames when this is unnecessary ... Some instructions do not create new values, they transform existing values in some way (bitcast, getelementptr, etc.). Do not store them in the stack object. This lowers the size of the repulsion demo from 100kB to 98kB (with a baseline of 72kB for the leaking GC). That's a useful reduction in file size.	2019-07-08 00:02:28 +02:00
