* [OpenCL] Accept .rgba in OpenCL 3.0Sven van Haastregt2021-04-123-9/+17
| | | | | | | | | | | | | | The .rgba vector component accessors are supported in OpenCL C 3.0. Previously, the diagnostic would check `OpenCLVersion` for version 2.2 (value 220) and report those accessors are an OpenCL 2.2 feature. However, there is no "OpenCL C version 2.2", so change the check and diagnostic text to 3.0 only. A spurious `OpenCLVersion` argument was passed into the diagnostic; remove that.

* [DebugInfo] Fix the mismatching between C++ language tags and Dwarf versions.Esme-Yi2021-04-123-3/+16
| | | | | | | | Summary: The tags DW_LANG_C_plus_plus_14 and DW_LANG_C_plus_plus_11, introduced in Dwarf-5, are unexpected in previous versions. Fixing the mismathing doesn't have any drawbacks for any other debuggers, but helps dbx. Reviewed By: aprantl, shchenz Differential Revision: https://reviews.llvm.org/D99250
* [clang][AST] Handle overload callee type in CallExpr::getCallReturnType.Balázs Kéri2021-04-122-0/+74
| | | | | | | | | | | | | | The function did not handle every case. In some cases this caused assertion failure. After the fix the function returns DependentTy if the exact return type can not be determined. It seems that clang itself does not call the function in the affected cases but some checker or other code may call it. Reviewed By: hokein Differential Revision: https://reviews.llvm.org/D95244

* [Clang][Coroutine][DebugInfo] In c++ coroutine, clang will emit different ↵yifeng.dongyifeng2021-04-127-13/+168
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | debug info variables for parameters and move-parameters. The first one is the real parameters of the coroutine function, the other one just for copying parameters to the coroutine frame. Considering the following c++ code: ``` struct coro { ... }; coro foo(struct test & t) { ... co_await suspend_always(); ... co_await suspend_always(); ... co_await suspend_always(); } int main(int argc, char *argv[]) { auto c = foo(...); c.handle.resume(); ... } ``` Function foo is the standard coroutine function, and it has only one parameter named t (ignoring this at first), when we use the llvm code to compile this function, we can get the following ir: ``` !2921 = distinct !DISubprogram(name: "foo", linkageName: "_ZN6Object3fooE4test", scope: !2211, file: !45, li\ ne: 48, type: !2329, scopeLine: 48, flags: DIFlagPrototyped | DIFlagAllCallsDescribed, spFlags: DISPFlagDefi\ nition | DISPFlagOptimized, unit: !44, declaration: !2328, retainedNodes: !2922) !2924 = !DILocalVariable(name: "t", arg: 2, scope: !2921, file: !45, line: 48, type: !838) ... !2926 = !DILocalVariable(name: "t", scope: !2921, type: !838, flags: DIFlagArtificial) ``` We can find there are two `the same` DIVariable named t in the same dwarf scope for foo.resume. And when we try to use llvm-dwarfdump to dump the dwarf info of this elf, we get the following output: ``` 0x00006684: DW_TAG_subprogram DW_AT_low_pc (0x00000000004013a0) DW_AT_high_pc (0x00000000004013a8) DW_AT_frame_base (DW_OP_reg7 RSP) DW_AT_object_pointer (0x0000669c) DW_AT_GNU_all_call_sites (true) DW_AT_specification (0x00005b5c "_ZN6Object3fooE4test") 0x000066a5: DW_TAG_formal_parameter DW_AT_name ("t") DW_AT_decl_file ("/disk1/yifeng.dongyifeng/my_code/llvm/build/bin/coro-debug-1.cpp") DW_AT_decl_line (48) DW_AT_type (0x00004146 "test") 0x000066ba: DW_TAG_variable DW_AT_name ("t") DW_AT_type (0x00004146 "test") DW_AT_artificial (true) ``` The elf also has two 't' in the same scope. But unluckily, it might let the debugger confused. And failed to print parameters for O0 or above. This patch will make coroutine parameters and move parameters use the same DIVar and try to fix the problems that I mentioned before.

* Handle alloc_size attribute on function pointersAlex Richardson2021-04-098-16/+253
| | | | | | | | | | | | | | | | | I have been trying to statically find and analyze all calls to heap allocation functions to determine how many of them use sizes known at compile time vs only at runtime. While doing so I saw that quite a few projects use replaceable function pointers for heap allocation and noticed that clang was not able to annotate functions pointers with alloc_size. I have changed the Sema checks to allow alloc_size on all function pointers and typedefs for function pointers now and added checks that these attributes are propagated to the LLVM IR correctly. With this patch we can also compute __builtin_object_size() for calls to allocation function pointers with the alloc_size attribute.

| | | | | | | | | | | | | | | | | | The backend can't handle this and will throw a fatal error from type legalization. It's easy enough to fix that for this intrinsic by just splitting the IR intrinsic since it works on individual bytes. There will be other intrinsics in the future that would be harder to support through splitting, for example grev, gorc, and shfl. Those would require a compare and a select be inserted to check the MSB of their control input. This patch adds support for preventing this in the frontend with a nice diagnostic.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds two debugging options in the new Flang driver (flang-new): *fdebug-unparse-no-sema *fdebug-dump-parse-tree-no-sema Each of these options combines two options from the "throwaway" driver (left: f18, right: flang-new): * `-fdebug-uparse -fdebug-no-semantics` --> `-fdebug-unparse-no-sema` * `-fdebug-dump-parse-tree -fdebug-no-semantics` --> `-fdebug-dump-parse-tree-no-sema` There are no plans to implement `-fdebug-no-semantics` in the new driver. Such option would be too powerful. Also, it would only make sense when combined with specific frontend actions (`-fdebug-unparse` and `-fdebug-dump-parse-tree`). Instead, this patch adds 2 specialised options listed above. Each of these is implemented through a dedicated FrontendAction (also added). The new frontend actions are implemented in terms of a new abstract base action: `PrescanAndSemaAction`. This new base class was required so that we can have finer control over what steps within the frontend are executed: * `PrescanAction`: run the _prescanner_ * `PrescanAndSemaAction`: run the _prescanner_ and the _parser_ (new in this patch) * `PrescanAndSemaAction`: run the _prescanner_, _parser_ and run the _semantic checks_ This patch introduces `PrescanAndParseAction::BeginSourceFileAction`. Apart from the semantic checks removed at the end, it is similar to `PrescanAndSemaAction::BeginSourceFileAction`. Differential Revision: https://reviews.llvm.org/D99645

This provides an optimization of the sequential version that works on a word at a time, using (documented) bithacks to provide a portable vectorization. When preprocessing the sqlite amalgamation, this yields a sweet 3% speedup.
