[InstCombine] Do an about-face on how LLVM canonicalizes (cast (load ...)) and (load (cast ...)): canonicalize toward the former. Historically, we've tried to load using the type of the *pointer*, and tried to match that type as closely as possible removing as many pointer casts as we could and trading them for bitcasts of the loaded value. This is deeply and fundamentally wrong. Repeat after me: memory does not have a type! This was a hard lesson for me to learn working on SROA. There is only one thing that should actually drive the type used for a pointer, and that is the type which we need to use to load from that pointer. Matching up pointer types to the loaded value types is very useful because it minimizes the physical size of the IR required for no-op casts. Similarly, the only thing that should drive the type used for a loaded value is *how that value is used*! Again, this minimizes casts. And in fact, the *only* thing motivating types in any part of LLVM's IR are the types used by the operations in the IR. We should match them as closely as possible. I've ended up removing some tests here as they were testing bugs or behavior that is no longer present. Mostly though, this is just cleanup to let the tests continue to function as intended. The only fallout I've found so far from this change was SROA and I have fixed it to not be impeded by the different type of load. If you find more places where this change causes optimizations not to fire, those too are likely bugs where we are assuming that the type of pointers is "significant" for optimization purposes. llvm-svn: 220138

[InstCombine] Change LLVM To canonicalize toward the value type being stored rather than the pointer type. This change is analogous to r220138 which changed the canonicalization for loads. The rationale is the same: memory does not have a type, operations (and thus the values they produce) have a type. We should match that type as closely as possible rather than reading some form of semantics into the pointer type. With this change, loads and stores should no longer be made with nonsensical types for the values that tehy load and store. This is particularly important when trying to match specific loaded and stored types in the process of doing other instcombines, which is what led me down this twisty maze of miscanonicalization. I've put quite some effort into looking through IR to find places where LLVM's optimizer was being unreasonably conservative in the face of mismatched load and store types, however it is possible (let's say, likely!) I have missed some. If you see regressions here, or from r220138, the likely cause is some part of LLVM failing to cope with load and store types differing. Test cases appreciated, it is important that we root all of these out of LLVM. llvm-svn: 222748

Similarly, the only thing that should drive the type used for a loaded value is *how that value is used*! Again, this minimizes casts. And in fact, the *only* thing motivating types in any part of LLVM's IR are the types used by the operations in the IR. We should match them as closely as possible. I've ended up removing some tests here as they were testing bugs or behavior that is no longer present. Mostly though, this is just cleanup to let the tests continue to function as intended. The only fallout I've found so far from this change was SROA and I have fixed it to not be impeded by the different type of load. If you find more places where this change causes optimizations not to fire, those too are likely bugs where we are assuming that the type of pointers is "significant" for optimization purposes. llvm-svn: 220138

[InstCombine] Change LLVM To canonicalize toward the value type being stored rather than the pointer type. This change is analogous to r220138 which changed the canonicalization for loads. The rationale is the same: memory does not have a type, operations (and thus the values they produce) have a type. We should match that type as closely as possible rather than reading some form of semantics into the pointer type. With this change, loads and stores should no longer be made with nonsensical types for the values that tehy load and store. This is particularly important when trying to match specific loaded and stored types in the process of doing other instcombines, which is what led me down this twisty maze of miscanonicalization. I've put quite some effort into looking through IR to find places where LLVM's optimizer was being unreasonably conservative in the face of mismatched load and store types, however it is possible (let's say, likely!) I have missed some. If you see regressions here, or from r220138, the likely cause is some part of LLVM failing to cope with load and store types differing. Test cases appreciated, it is important that we root all of these out of LLVM. llvm-svn: 222748

[InstCombine] Do an about-face on how LLVM canonicalizes (cast (load ...)) and (load (cast ...)): canonicalize toward the former. Historically, we've tried to load using the type of the *pointer*, and tried to match that type as closely as possible removing as many pointer casts as we could and trading them for bitcasts of the loaded value. This is deeply and fundamentally wrong. Repeat after me: memory does not have a type! This was a hard lesson for me to learn working on SROA. There is only one thing that should actually drive the type used for a pointer, and that is the type which we need to use to load from that pointer. Matching up pointer types to the loaded value types is very useful because it minimizes the physical size of the IR required for no-op casts. Similarly, the only thing that should drive the type used for a loaded value is *how that value is used*! Again, this minimizes casts. And in fact, the *only* thing motivating types in any part of LLVM's IR are the types used by the operations in the IR. We should match them as closely as possible. I've ended up removing some tests here as they were testing bugs or behavior that is no longer present. Mostly though, this is just cleanup to let the tests continue to function as intended.
