Jessica Paquette e49374d009 Add remarks describing when a pass changes the IR instruction count of a module ... This patch adds a remark which tells the user when a pass changes the number of IR instructions in a module. It can be enabled by using -Rpass-analysis=size-info. The point of this is to make it easier to collect statistics on how passes modify programs in terms of code size. This is similar in concept to timing reports, but using a remark-based interface makes it easy to diff changes over multiple compilations of the same program. By adding functionality like this, we can see * Which passes impact code size the most * How passes impact code size at different optimization levels * Which pass might have contributed the most to an overall code size regression The patch lives in the legacy pass manager, but since it's simply emitting remarks, it shouldn't be too difficult to adapt the functionality to the new pass manager as well. This can also be adapted to handle MachineInstr counts in code gen passes. https://reviews.llvm.org/D38768 llvm-svn: 332739		2018-05-18 17:26:39 +00:00
