2013-03-12LibCallSimplifier: optimize speed for short-lived instancesMeador Inge
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.

2013-03-11Remove support for versioned debug info.David Blaikie
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

2013-03-11Upgrading debug info test cases to be (more) compatible with the current ↵David Blaikie
debug info format. These cases were found by further work to remove support for debug info versioning. Common cleanups (other than changing the version info in the tag field) included adding the last parameter to compile_units (recently added for fission support) and other cases of trailing fields in lexical blocks, compile units, and subprograms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176834 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-08Disable statistics on Release builds and move tests that depend on -stats.Jan Wen Voung
Summary: Statistics are still available in Release+Asserts (any +Asserts builds), and stats can also be turned on with LLVM_ENABLE_STATS. Move some of the FastISel stats that were moved under DEBUG() back out of DEBUG(), since stats are disabled across the board now. Many tests depend on grepping "-stats" output. Move those into a orig_dir/Stats/. so that they can be marked as unsupported when building without statistics.
