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

Output per-function size-info remarks This patch adds per-function size information remarks. Previously, passing -Rpass-analysis=size-info would only give you per-module changes. By adding the ability to do this per-function, it's easier to see which functions contributed the most to size changes. https://reviews.llvm.org/D51467 llvm-svn: 341588

; * Positive, nonzero sizes before/after for whole-module remarks
; (It's okay to have nonzero sizes in per-function remarks, since a function
; can be created/destroyed by a pass.)

; * Nonzero deltas
; * Sizes are being tracked properly across multiple remarks. E.g, if we have
; original_count_1, final_count_1, and
; original_count_2, final_count_2,
; Then original_count_2 == final_count_1.
; For these remarks, the "function" field in the YAML file doesn't matter.
; Each of the testcases work by combining the output remarks with the
; optimization record emit using -pass-remarks-output. This is done to prevent
; test flakiness wrt instruction counts, but also ensure that the output values
; are equivalent in both outputs.

Fix typo in size remarks for module passes ModuleCount = InstrCount was incorrect. It should have been InstrCount = ModuleCount. This was making it emit an extra, incorrect remark for Print Module IR. The test didn't catch this, because it didn't ensure that the only remark output was from the desired pass. So, it was possible to have an extra remark come through and not fail. Updated the test so that we ensure that the last remark that's output comes from the desired pass. This is done by ensuring that whatever is being read after the last remark is YAML output rather than some incorrect garbage. llvm-svn: 341267

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.

Fix typo in size remarks for module passes ModuleCount = InstrCount was incorrect. It should have been InstrCount = ModuleCount. This was making it emit an extra, incorrect remark for Print Module IR. The test didn't catch this, because it didn't ensure that the only remark output was from the desired pass. So, it was possible to have an extra remark come through and not fail. Updated the test so that we ensure that the last remark that's output comes from the desired pass. This is done by ensuring that whatever is being read after the last remark is YAML output rather than some incorrect garbage. llvm-svn: 341267
