* Add support for fast-math flags to the FCmp instruction.James Molloy2015-07-101-2/+20
| | | | | | | | | | | | | | FCmp behaves a lot like a floating-point binary operator in many ways, and can benefit from fast-math information. Flags such as nsz and nnan can affect if this fcmp (in combination with a select) can be treated as a fminnum/fmaxnum operation. This adds backwards-compatible bitcode support, IR parsing and writing, LangRef changes and IRBuilder changes. I'll need to audit InstSimplify and InstCombine in a followup to find places where flags should be copied. llvm-svn: 241901

* Change APInt comparison with uint64_t.Pawel Bylica2015-07-011-0/+127
| | | | | | | | | | | | | | | | | Summary: This patch changes the way APInt is compared with a value of type uint64_t. Before the uint64_t value was truncated to the size of APInt before comparison. Now the comparison takes into account full 64-bit precision. Test Plan: Unit tests added. No regressions. Self-hosted check-all done as well.

* [DebugInfo] Let IRBuilder::SetInsertPoint(BB::iterator) update current debug ↵Alexey Samsonov2015-06-301-0/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | location. IRBuilder::SetInsertPoint(BB, BB::iterator) is an older version of IRBuilder::SetInsertPoint(Instruction). However, the latter updates the current debug location of emitted instruction, while the former doesn't, which is confusing. Unify the behavior of these methods: now they both set current debug location to the debug location of instruction at insertion point. The callers of IRBuilder::SetInsertPoint(BB, BB::iterator) doesn't seem to depend on the old behavior (keeping the original debug info location). On the contrary, sometimes they (e.g. SCEV) *should* be updating debug info location, but don't. I'll look at gdb bots after the commit to check that we don't regress on debug info somewhere. This change may make line table more fine-grained, thus increasing debug info size. I haven't observed significant increase, though: it varies from negligible to 0.3% on several binaries and self-hosted Clang. This is yet another change targeted at resolving PR23837. llvm-svn: 241101

* Add a DIModule metadata node to the IR.Adrian Prantl2015-06-291-0/+34
| | | | | | | | | | | | | | | | | | | It is meant to be used to record modules @imported by the current compile unit, so a debugger an import the same modules to replicate this environment before dropping into the expression evaluator. DIModule is a sibling to DINamespace and behaves quite similarly. In addition to the name of the module it also records the module configuration details that are necessary to uniquely identify the module. This includes the configuration macros (e.g., -DNDEBUG), the include path where the module.map file is to be found, and the isysroot. The idea is that the backend will turn this into a DW_TAG_module. http://reviews.llvm.org/D9614 rdar://problem/20965932 llvm-svn: 241017
* IR: Expose ModuleSlotTracker in Value::print()Duncan P. N. Exon Smith2015-06-272-0/+82
| | | | | | | | | | | | | | | | | | | Allow callers of `Value::print()` and `Metadata::print()` to pass in a `ModuleSlotTracker`. This allows them to pay only once for calculating module-level slots (such as Metadata). This is related to PR23865, where there was a huge cost for `MachineFunction::print()`. Although I don't have a *particular* user in mind for this new code, I have hit big slowdowns before when running `opt -debug`, and I think this will be useful. Going forward, if someone hits a big slowdown with `print()` statements, they can create a `ModuleSlotTracker` and send it through. Similarly, adding support to `Value::dump()` and `Metadata::dump()` should be trivial. I added unit tests to be sure the `print()` functions actually behave the same way with and without the slot tracker. llvm-svn: 240867
* AsmPrinter: Use an intrusively linked list for DIE::ChildrenDuncan P. N. Exon Smith2015-06-251-64/+63
| | | | | | | | | | | | | | Replace the `std::vector<>` for `DIE::Children` with an intrusively linked list. This is a strict memory improvement: it requires no auxiliary storage, and reduces `sizeof(DIE)` by one pointer. It also factors out the DIE-related malloc traffic. This drops llc memory usage from 735 MB down to 718 MB, or ~2.3%. (I'm looking at `llc` memory usage on `verify-uselistorder.lto.opt.bc`; see r236629 for details.) llvm-svn: 240736
* AsmPrinter: Convert DIE::Values to a linked listDuncan P. N. Exon Smith2015-06-251-161/+193
| | | | | | | | | | | | | | | | Change `DIE::Values` to a singly linked list, where each node is allocated on a `BumpPtrAllocator`. In order to support `push_back()`, the list is circular, and points at the tail element instead of the head. I abstracted the core list logic out to `IntrusiveBackList` so that it can be reused for `DIE::Children`, which also cares about `push_back()`. This drops llc memory usage from 799 MB down to 735 MB, about 8%. (I'm looking at `llc` memory usage on `verify-uselistorder.lto.opt.bc`; see r236629 for details.) llvm-svn: 240733

* [ADT] Teach DenseMap to support StringRef keys.Chandler Carruth2015-06-241-0/+25
| | | | | | | | | | | | While often you want to use something specialized like StringMap, when the strings already have persistent storage a normal densemap over them can be more efficient. This can't go into StringRef.h because of really obnoxious header chains from the hashing code to the endian detection code to CPU feature detection code to StringMap. llvm-svn: 240528
* ADT: Add a string APSInt constructor.Alex Lorenz2015-06-231-0/+19
| | | | | | | | | | | | This commit moves the APSInt initialization code that's used by the LLLexer class into a new APSInt constructor that constructs APSInts from strings. This change is useful for MIR Serialization, as it would allow the MILexer class to use the same APSInt initialization as LLexer when parsing immediate machine operands. llvm-svn: 240436
* AsmParser: Extend the API to make the global value and metadata node slot ↵Alex Lorenz2015-06-231-0/+20
| | | | | | | | | | | | | | | | | | mappings publicly accessible. This commit creates a new structure called 'SlotMapping' in the AsmParser library. This structure can be passed into the public parsing APIs from the AsmParser library in order to extract the data structures that map from slot numbers to unnamed global values and metadata nodes. This change is useful for MIR Serialization, as the MIR Parser has to lookup the unnamed global values and metadata nodes by their slot numbers. Reviewers: Duncan P. N.

* Move the personality function from LandingPadInst to FunctionDavid Majnemer2015-06-172-4/+3
| | | | | | | | | | | | | | | | | | | The personality routine currently lives in the LandingPadInst. This isn't desirable because: - All LandingPadInsts in the same function must have the same personality routine. This means that each LandingPadInst beyond the first has an operand which produces no additional information. - There is ongoing work to introduce EH IR constructs other than LandingPadInst. Moving the personality routine off of any one particular Instruction and onto the parent function seems a lot better than have N different places a personality function can sneak onto an exceptional function.
