* ARM: Compute MaxCallFrame size earlyMatthias Braun2017-05-058-12/+57
| | | | | | | | | | | | | | | | | This exposes a method in MachineFrameInfo that calculates MaxCallFrameSize and calls it after instruction selection in the ARM target. This avoids ARMBaseRegisterInfo::canRealignStack()/ARMFrameLowering::hasReservedCallFrame() giving different answers in early/late phases of codegen. The testcase shows a particular nasty example result of that where we would fail to properly align an alloca. Differential Revision: https://reviews.llvm.org/D32622 llvm-svn: 302303
* [CodeView] Reserve TypeDatabase records up front.Zachary Turner2017-05-052-1/+6
| | | | | | | | | | | | | Most of the time we know exactly how many type records we have in a list, and we want to use the visitor to deserialize them into actual records in a database. Previously we were just using push_back() every time without reserving the space up front in the vector. This is obviously terrible from a performance standpoint, and it's not uncommon to have PDB files with half a million type records, where the performance degredation was quite noticeable. llvm-svn: 302302

* MIParser/MIRPrinter: Compute block successors if not explicitely specifiedMatthias Braun2017-05-054-44/+107
| | | | | | | | | | | | | | | | | - MIParser: If the successor list is not specified successors will be added based on basic block operands in the block and possible fallthrough. - MIRPrinter: Adds a new `simplify-mir` option, with that option set: Skip printing of block successor lists in cases where the parser is guaranteed to reconstruct it. This means we still print the list if some successor cannot be determined (happens for example for jump tables), if the successor order changes or branch probabilities being unequal.

* Simplify dbg.value handling in SDISel with early returnsReid Kleckner2017-05-051-35/+23
| | | | | | | | | | | | | | No functional change other than improving dbgs logging accuracy on constant dbg values. Previously we would add things like "i32 42" as debug values, and then log that we were dropping the debug info, which is silly. Delete some dead code that was checking for static allocas. This remained after r207165, but served no purpose. Currently, static alloca dbg.values are always sent through the DanglingDebugInfoMap, and are usually made valid the first time the alloca is used. llvm-svn: 302267

* [pdb] Don't verify TPI hash values up front.Zachary Turner2017-05-041-23/+3
| | | | | | | | | | | | | | | | | | | | | | | | Verifying the hash values as we are currently doing results in iterating every type record before the user even tries to access the first one, and the API user has no control over, or ability to hook into this process. As a result, when the user wants to iterate over types to print them or index them, this results in a second iteration over the same list of types. When there's upwards of 1,000,000 type records, this is obviously quite undesirable. This patch raises the verification outside of TpiStream , and llvm-pdbdump hooks a hash verification visitor into the normal dumping process. So we still verify the hash records, but we can do it while not requiring a second iteration over the type stream. Differential Revision: https://reviews.llvm.org/D32873 llvm-svn: 302206
* [PDB] Don't build the entire source file list up front.Zachary Turner2017-05-046-117/+294
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | I tried to run llvm-pdbdump on a very large (~1.5GB) PDB to try and identify show-stopping performance problems. This patch addresses the first such problem. When loading the DBI stream, before anyone has even tried to access a single record, we build an in memory map of every source file for every module. In the particular PDB I was using, this was over 85 million files. Specifically, the complexity is O(m*n) where m is the number of modules and n is the average number of source files (including headers) per module. The whole reason for doing this was so that we could have constant time access to any module and any of its source file lists. However, we can still get O(1) access to the source file list for a given module with a simple O(m) precomputation, and access to the list of modules is already O(1) anyway. So this patches reduces the O(m*n) up-front precomputation to an O(m) one, where n is ~6,500 and n*m is about 85 million in my pathological test case.

* [InstSimplify] add folds for or-of-casted-icmpsSanjay Patel2017-05-041-36/+46
| | | | | | | | | | | | | | | | | The sibling folds for 'and' with casts were added with https://reviews.llvm.org/rL273200. This is a preliminary step for adding the 'or' variants for the folds added with https://reviews.llvm.org/rL301260. The reason for the strange form with constant LHS in the 1st test is because there's another missing fold in that case for the inverted predicate. That should be fixed when we add the ConstantRange functionality for 'or-of-icmps' that already exists for 'and-of-icmps'. I'm hoping to share more code for the and/or cases, so we won't have these differences. This will allow us to remove code from InstCombine. It's also possible that we can remove some code here in InstSimplify. I think we have some duplicated folds because patterns are not matched in a general way.
