2017-06-05Add support for #pragma clang sectionJaved Absar1-1/+29
This patch provides a means to specify section-names for global variables, functions and static variables, using #pragma directives. This feature is only defined to work sensibly for ELF targets. One can specify section names as: #pragma clang section bss="myBSS" data="myData" rodata="myRodata" text="myText" One can "unspecify" a section name with empty string e.g. #pragma clang section bss="" data="" text="" rodata="" Reviewers: Roger Ferrer, Jonathan Roelofs, Reid Kleckner Differential Revision: https://reviews.llvm.org/D33412 llvm-svn: 304705

Summary: This change allows us to add arg1 logging support to functions through the special case list provided through -fxray-always-instrument=. This is useful for adding arg1 logging to functions that are either in headers that users don't have control over (i.e. cannot change the source) or would rather not do. It only takes effect when the pattern is matched through the "fun:" special case, as a category.

2017-05-20CodeGenModule: Always output wchar_size, check LLVM assumptions.Matthias Braun1-6/+13
Re-commit r303463 now that LLVM is fixed and adjust some lit tests. llvm::TargetLibraryInfo needs to know the size of wchar_t to work on functions like `wcslen`. This patch changes clang to always emit the wchar_size module flag (it would only do so for ARM previously). This also adds an `assert()` to ensure the LLVM defaults based on the target triple are in sync with clang. Differential Revision: https://reviews.llvm.org/D32982 llvm-svn: 303478

2017-05-18CodeGen: Cast alloca to expected address spaceYaxun Liu1-0/+1
Alloca always returns a pointer in alloca address space, which may be different from the type defined by the language. For example, in C++ the auto variables are in the default address space. Therefore cast alloca to the expected address space when necessary. Differential Revision: https://reviews.llvm.org/D32248 llvm-svn: 303370

2017-04-27[Profile] Add off-by-default -Wprofile-instr-missing warningVedant Kumar1-3/+7
Clang warns that a profile is out-of-date if it can't find a profile record for any function in a TU. This warning became noisy after llvm started allowing dead-stripping of instrumented functions. To fix this, this patch changes the existing profile out-of-date warning (-Wprofile-instr-out-of-date) so that it only complains about mismatched data. Further, it introduces a new, off-by-default warning about missing function data (-Wprofile-instr-missing). Differential Revision: https://reviews.llvm.org/D28867 llvm-svn: 301570

2017-04-13[IR] Make getParamAttributes take argument numbers, not ArgNo+1Reid Kleckner1-1/+1
Add hasParamAttribute() and use it instead of hasAttribute(ArgNo+1, Kind) everywhere. The fact that the AttributeList index for an argument is ArgNo+1 should be a hidden implementation detail. NFC llvm-svn: 300272
2017-04-13[IR] Take func, ret, and arg attrs separately in AttributeList::getReid Kleckner1-12/+8
This seems like a much more natural API, based on Derek Schuff's comments on r300015. It further hides the implementation detail of AttributeList that function attributes come last and appear at index ~0U, which is easy for the user to screw up. git diff says it saves code as well: 97 insertions(+), 137 deletions(-) This also makes it easier to change the implementation, which I want to do next. llvm-svn: 300153
2017-04-12[IR] Add AttributeSet to hide AttributeSetNode* again, NFCReid Kleckner1-1/+1
Summary: For now, it just wraps AttributeSetNode*. Eventually, it will hold AvailableAttrs as an inline bitset, and adding and removing enum attributes will be super cheap. This sinks AttributeSetNode back down to lib/IR/AttributeImpl.h. Reviewers: pete, chandlerc Subscribers: llvm-commits, jfb Differential Revision: https://reviews.llvm.org/D31940 llvm-svn: 300014
2017-04-11Modular Codegen: Support homing debug info for types in modular objectsDavid Blaikie1-0/+5
Matching the function-homing support for modular codegen. Any type implicitly (implicit template specializations) or explicitly defined in a module is attached to that module's object file and omitted elsewhere (only a declaration used if necessary for references). llvm-svn: 299987
2017-04-10Reland "[IR] Make AttributeSetNode public, avoid temporary AttributeList copies"Reid Kleckner1-10/+4
This re-lands r299875. I introduced a bug in Clang code responsible for replacing K&R, no prototype declarations with a real function definition with a prototype. The bug was here: // Collect any return attributes from the call. - if (oldAttrs.hasAttributes(llvm::AttributeList::ReturnIndex)) - newAttrs.push_back(llvm::AttributeList::get(newFn->getContext(), - oldAttrs.getRetAttributes())); + newAttrs.push_back(oldAttrs.getRetAttributes()); Previously getRetAttributes() carried AttributeList::ReturnIndex in its AttributeList. Now that we return the AttributeSetNode* directly, it no longer carries that index, and we call this overload with a single node: AttributeList::get(LLVMContext&, ArrayRef<AttributeSetNode*>) That aborted with an assertion on x86_32 targets. I added an explicit triple to the test and added CHECKs to help find issues like this in the future sooner. llvm-svn: 299899
2017-04-07[cfi] Emit __cfi_check stub in the frontend.Evgeniy Stepanov1-1/+3
Previously __cfi_check was created in LTO optimization pipeline, which means LLD has no way of knowing about the existence of this symbol without rescanning the LTO output object. As a result, LLD fails to export __cfi_check, even when given --export-dynamic-symbol flag. llvm-svn: 299806

2017-03-30[XRay] Add -fxray-{always,never}-instrument= flags to clangDean Michael Berris1-0/+24
Summary: The -fxray-always-instrument= and -fxray-never-instrument= flags take filenames that are used to imbue the XRay instrumentation attributes using a whitelist mechanism (similar to the sanitizer special cases list). We use the same syntax and semantics as the sanitizer blacklists files in the implementation. As implemented, we respect the attributes that are already defined in the source file (i.e. those that have the [[clang::xray_{always,never}_instrument]] attributes) before applying the always/never instrument lists.

2017-03-23[CodeGen] Emit a CoreFoundation link guard when @available is usedAlex Lorenz1-0/+1
After r297760, __isOSVersionAtLeast in compiler-rt loads the CoreFoundation symbols at runtime. This means that `@available` will always fail when used in a binary without a linked CoreFoundation. This commit forces Clang to emit a reference to a CoreFoundation symbol when `@available` is used to ensure that linking will fail when CoreFoundation isn't linked with the build product. rdar://31039592 Differential Revision: https://reviews.llvm.org/D30977 llvm-svn: 298588

2017-02-15[dllimport] Check for dtor references in functionsHans Wennborg1-13/+31
Destructor references are not modelled explicitly in the AST. This adds checks for destructor calls due to variable definitions and temporaries. If a dllimport function references a non-dllimport destructor, it must not be emitted available_externally, as the referenced destructor might live across the DLL boundary and isn't exported. llvm-svn: 295258
2017-02-15[dllimport] Look through typedefs and arrays in HasNonDllImportDtorHans Wennborg1-1/+1
The function is used to check whether a type is a class with non-dllimport destructor. It needs to look through typedefs and array types. llvm-svn: 295257
2017-01-30Prototype of modules codegenDavid Blaikie1-1/+1
First pass at generating weak definitions of inline functions from module files (& skipping (-O0) or emitting available_externally (optimizations) definitions where those modules are used). External functions defined in modules are emitted into the modular object file as well (this may turn an existing ODR violation (if that module were imported into multiple translations) into valid/linkable code). Internal symbols (static functions, for example) are not correctly supported yet. The symbol will be produced, internal, in the modular object - unreferenceable from the users.
