* [Support][Path] Don't inf loop if creating the parent directory fails.Michael J. Spencer2013-03-121-1/+7
| | | | | | Patch by Paul Robinson. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176908 91177308-0d34-0410-b5e6-96231b3b80d8
* Update debug info test cases with empty SplitDebugFilename field.David Blaikie2013-03-1275-81/+81
| | | | | | | | | | | | This could be 'null' or the empty string, DIDescriptor::getStringField coalesces the two cases anyway so it's just a matter of legible/efficient representation. The change in behavior of the DICompileUnit::get* functions could be subsumed by the full verification check - but ideally that should just be an assertion if we could front-load the actual debug info metadata failure paths. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176907 91177308-0d34-0410-b5e6-96231b3b80d8
* ARM cost model: Increase the cost for vector casts that use the stackArnold Schwaighofer2013-03-122-0/+22
| | | | | | | | | | | | | | | | | | | | | | | Increase the cost of v8/v16-i8 to v8/v16-i32 casts and truncates as the backend currently lowers those using stack accesses. This was responsible for a significant degradation on MultiSource/Benchmarks/Trimaran/enc-pc1/enc-pc1 where we vectorize one loop to a vector factor of 16. After this patch we select a vector factor of 4 which will generate reasonable code. unsigned char cle[32]; void test(short c) { unsigned short compte; for (compte = 0; compte <= 31; compte++) { cle[compte] = cle[compte] ^ c; } } radar://13220512 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176898 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a doFinalization method to the DataLayout pass.Pete Cooper2013-03-122-0/+10
| | | | | | | | | | | | | | | | This pass is meant to be immutable, however it holds mutable state to cache StructLayouts. This method will allow the pass manager to clear the mutable state between runs. Note that unfortunately it is still necessary to have the destructor, even though it does the same thing as doFinalization. This is because most TargetMachines embed a DataLayout on which doFinalization isn't run as its never added to the pass manager. I also didn't think it was necessary to complication things with a deInit method for which doFinalization and ~DataLayout both call as there's only one field of mutable state. If we had more fields to finalize i'd have added this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176877 91177308-0d34-0410-b5e6-96231b3b80d8

* Don't reserve R2 on Darwin/PPCHal Finkel2013-03-127-49/+36
| | | | | | | | | | | Now that only the register-scavenger version of the CR spilling code remains, we no longer need the Darwin R2 hack. Darwin can use R0 as a spare register in any case where the System V ABI uses it (R0 is special architecturally, and so is reserved under all common ABIs). A few test cases needed to be updated to reflect the register-allocation changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176868 91177308-0d34-0410-b5e6-96231b3b80d8

* LibCallSimplifier: optimize speed for short-lived instancesMeador Inge2013-03-121-177/+225
| | | | | | | | | | | | | | | | | | | | | | | | | | Nadav reported a performance regression due to the work I did to merge the library call simplifier into instcombine [1]. The issue is that a new LibCallSimplifier object is being created whenever InstCombiner::runOnFunction is called. Every time a LibCallSimplifier object is used to optimize a call it creates a hash table to map from a function name to an object that optimizes functions of that name. For short-lived LibCallSimplifier instances this is quite inefficient. Especially for cases where no calls are actually simplified. This patch fixes the issue by dropping the hash table and implementing an explicit lookup function to correlate the function name to the object that optimizes functions of that name. This avoids the cost of always building and destroying the hash table in cases where the LibCallSimplifier object is short-lived and avoids the cost of building the table when no simplifications are actually preformed. On a benchmark containing 100,000 calls where none of them are simplified I noticed a 30% speedup. On a benchmark containing 100,000 calls where all of them are simplified I noticed an 8% speedup.

* Remove support for versioned debug info.David Blaikie2013-03-116-354/+119
| | | | | | | | | | | | | | | | | | | | | | | | Versioned debug info support has been a burden to maintain & also compromised current debug info verification by causing test cases testing old debug info to remain rather than being updated to the latest. It also makes it hard to add or change the metadata schema by requiring various backwards-compatibility in the DI* hierarchy. So it's being removed in preparation for new changes to the schema to tidy up old/unnecessary fields and add new fields needed for new debug info (well, new to LLVM at least). The more surprising part of this is the changes to DI*::Verify - this became necessary due to the changes to AsmWriter. AsmWriter was relying on the version test to decide which bits of metadata were actually debug info when printing the comment annotations. Without the version information the tag numbers were too common & it would print debug info on random metadata that happened to start with an integer that matched a tag number. Instead this change makes the Verify functions more precise (just adding "number of operands" checks - not type checking those operands yet) & relies on that to decide which metadata is debug info metadata. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176838 91177308-0d34-0410-b5e6-96231b3b80d8
