[NFC][Py Reformat] Reformat python files in the rest of the dirs This is an ongoing series of commits that are reformatting our Python code. This catches the last of the python files to reformat. Since they where so few I bunched them together. Reformatting is done with black. If you end up having problems merging this commit because you have made changes to a python file, the best way to handle that is to run git checkout --ours <yourfile> and then reformat it with black. If you run into any problems, post to discourse about it and we will try to help.

[flang] Block construct A block construct is an execution control construct that supports declaration scopes contained within a parent subprogram scope or another block scope. (blocks may be nested.) This is implemented by applying basic scope processing to the block level. Name uniquing/mangling is extended to support this. The term "block" is heavily overloaded in Fortran standards. Prior name uniquing used tag B for common block objects. Existing tag choices were modified to free up B for block construct entities, and C for common blocks, and resolve additional issues with other tags. The "old tag -> new tag" changes can be summarized as: -> B -- block construct -> new B -> C -- common block C -> YI -- intrinsic type descriptor; not currently generated CT -> Y -- nonintrinsic type descriptor; not currently generated G -> N -- namelist group L -> -- block data; not needed -> deleted Existing name uniquing components consist of a tag followed by a name from user source code, such as a module, subprogram, or variable name. Block constructs are different in that they may be anonymous. (Like other constructs, a block may have a block-construct-name that can be used in exit statements, but this name is optional.) So blocks are given a numeric compiler-generated preorder index starting with B1, B2, and so on, on a per-procedure basis. Name uniquing is also modified to include component names for all containing procedures rather than for just the immediate host. This fixes an existing name clash bug with same-named entities in same-named host subprograms contained in different-named containing subprograms, and variations of the bug involving modules and submodules. F18 clause 9.7.3.1 (Deallocation of allocatable variables) paragraph 1 has a requirement that an allocated, unsaved allocatable local variable must be deallocated on procedure exit. The following paragraph 2 states: When a BLOCK construct terminates, any unsaved allocated allocatable local variable of the construct is deallocated. Similarly, F18 clause 7.5.6.3 (When finalization occurs) paragraph 3 has a requirement that a nonpointer, nonallocatable object must be finalized on procedure exit. The following paragraph 4 states: A nonpointer nonallocatable local variable of a BLOCK construct is finalized immediately before it would become undefined due to termination of the BLOCK construct. These deallocation and finalization requirements, along with stack restoration requirements, require knowledge of block exits. In addition to normal block termination at an end-block-stmt, a block may be terminated by executing a branching statement that targets a statement outside of the block. This includes Single-target branch statements: - goto - exit - cycle - return Bounded multiple-target branch statements: - arithmetic goto - IO statement with END, EOR, or ERR specifiers Unbounded multiple-target branch statements: - call with alternate return specs - computed goto - assigned goto Lowering code is extended to determine if one of these branches exits one or more relevant blocks or other constructs, and adds a mechanism to insert any necessary deallocation, finalization, or stack restoration code at the source of the branch. For a single-target branch it suffices to generate the exit code just prior to taking the indicated branch. Each target of a multiple-target branch must be analyzed individually. Where necessary, the code must first branch to an intermediate basic block that contains exit code, followed by a branch to the original target statement. This patch implements an activeConstructStack construct exit mechanism that queries a new activeConstruct PFT bit to insert stack restoration code at block exits. It ties in to existing code in ConvertVariable.cpp routine instantiateLocal which has code for finalization, making block exit finalization on par with subprogram exit finalization. Deallocation is as yet unimplemented for subprograms or blocks. This may result in memory leaks for affected objects at either the subprogram or block level. Deallocation cases can be addressed uniformly for both scopes in a future patch, presumably with code insertion in routine instantiateLocal. The exit code mechanism is not limited to block construct exits. It is also available for use with other constructs. In particular, it is used to replace custom deallocation code for a select case construct character selector expression where applicable. This functionality is also added to select type and associate constructs. It is available for use with other constructs, such as select rank and image control constructs, if that turns out to be necessary. Overlapping nonfunctional changes include eliminating "FIR" from some routine names and eliminating obsolete spaces in comments. | 3 年前 | |

[flang] Portability warning and documentation for an obscure extension A quotation mark can appear in a Fortran character literal by doubling it; for example, PRINT *, "'""'" prints '"'. When those doubled quotation marks are split by a free form line continuation, the continuation line should have an ampersand before the second quotation mark. But most compilers, including this one, allow the second quotation mark to appear as the first character on the continuation line, too. So this works: print *, "'"& "'" but it really should be written as: print *, "'"& &"'" Emit a portability warning and document that we support this near-universal extension.

[flang][docs][nfc] Refine FlangOptionsDocs.td Currently, FlangOptionsDocs.td doesn't specify ExcludedFlags which means that in the generated documentation file we expose flags that: * we don't necessarily won't to advertise to our users (e.g. hidden flags), or * are not supported altogether (e.g. CL options). This patch defines ExcludeFlags to fix that. The definition of ExcludeFlags was copied from Clang so that LLVM frontends have consistent documentation. It might be a bit counter-intuitive that IncludeFlags alone is not sufficient here. However, the current logic in ClangOptionDocEmitter.cpp will parse IncludeFlags and print all options that contains one of the included flags, as well as their aliases. So, for example, for -fopenmp (which is a supported Flang option), one would also get /fopenmp (i.e. CL mode equivalent for -fopenmp). By adding ExcludeFlags, we make sure that such aliases are excluded. I've also taken the liberty and moved FlangOptionsDocs.td. Originally it was located in Flang's "flang/include" directory, but there shouldn't be any implementation/documentation files there. Instead, I'm moving it to the "flang/docs" directory.

[flang] CUDA Fortran - part 1/5: parsing Begin upstreaming of CUDA Fortran support in LLVM Flang. This first patch implements parsing for CUDA Fortran syntax, including: - a new LanguageFeature enum value for CUDA Fortran - driver change to enable that feature for *.cuf and *.CUF source files - parse tree representation of CUDA Fortran syntax - dumping and unparsing of the parse tree - the actual parsers for CUDA Fortran syntax - prescanning support for !@CUF and !$CUF - basic sanity testing via unparsing and parse tree dumps ... along with any minimized changes elsewhere to make these work, mostly no-op cases in common::visitors instances in semantics and lowering to allow them to compile in the face of new types in variant<> instances in the parse tree. Because CUDA Fortran allows the kernel launch chevron syntax ("call foo<<<blocks, threads>>>()") only on CALL statements and not on function references, the parse tree nodes for CallStmt, FunctionReference, and their shared Call were rearranged a bit; this caused a fair amount of one-line changes in many files. More patches will follow that implement CUDA Fortran in the symbol table and name resolution, and then semantic checking. Differential Revision: https://reviews.llvm.org/D150159 | 3 年前 | |
[flang] Fix pointer definition semantic checking via refactoring The infrastructure in semantics that is used to check that the left-hand sides of normal assignment statements are really definable variables was not being used to check whether the LHSs of pointer assignments are modifiable, and so most cases of unmodifiable pointers are left undiagnosed. Rework the semantics checking for pointer assignments, NULLIFY statements, pointer dummy arguments, &c. so that cases of unmodifiable pointers are properly caught. This has been done by extracting all the various definability checking code that has been implemented for different contexts in Fortran into one new facility. The new consolidated definability checking code returns messages meant to be attached as "because: " explanations to context-dependent errors like "left-hand side of assignment is not definable". These new error message texts and their attached explanations affect many existing tests, which have been updated. The testing infrastructure was extended by another patch to properly compare warnings and explanatory messages, which had been ignored until recently.

[flang] Improve initializer semantics, esp. for component default values This patch plugs many holes in static initializer semantics, improves error messages for default initial values and other component properties in parameterized derived type instantiations, and cleans up several small issues noticed during development. We now do proper scalar expansion, folding, and type, rank, and shape conformance checking for component default initializers in derived types and PDT instantiations. The initial values of named constants are now guaranteed to have been folded when installed in the symbol table, and are no longer folded or scalar-expanded at each use in expression folding. Semantics documentation was extended with information about the various kinds of initializations in Fortran and when each of them are processed in the compiler. Some necessary concomitant changes have bulked this patch out a bit: * contextual messages attachments, which are now produced for parameterized derived type instantiations so that the user can figure out which instance caused a problem with a component, have been added as part of ContextualMessages, and their implementation was debugged * several APIs in evaluate::characteristics was changed so that a FoldingContext is passed as an argument rather than just its intrinsic procedure table; this affected client call sites in many files * new tools in Evaluate/check-expression.cpp to determine when an Expr actually is a single constant value and to validate a non-pointer variable initializer or object component default value * shape conformance checking has additional arguments that control whether scalar expansion is allowed * several now-unused functions and data members noticed and removed * several crashes and bogus errors exposed by testing this new code were fixed * a -fdebug-stack-trace option to enable LLVM's stack tracing on a crash, which might be useful in the future TL;DR: Initialization processing does more and takes place at the right times for all of the various kinds of things that can be initialized.

[Flang][driver] Update the docs Please note that the updated documentation reflects the design that we are working towards, but haven't implemented competely yet. We took this approach in order to provide a more holisitic and complete overview of the design. In particular, this document assumes that Flang's frontend and compiler driver can already generate code. This is still work-in-progress and is being developed on the fir-dev branch in the F18 repository [1].

[NFC][Py Reformat] Reformat python files in the rest of the dirs This is an ongoing series of commits that are reformatting our Python code. This catches the last of the python files to reformat. Since they where so few I bunched them together. Reformatting is done with black. If you end up having problems merging this commit because you have made changes to a python file, the best way to handle that is to run git checkout --ours <yourfile> and then reformat it with black. If you run into any problems, post to discourse about it and we will try to help.

[flang] Correct handling of null pointer initializers Fortran defines "null-init" null pointer initializers as being function references, syntactically, that have to resolve to calls to the intrinsic function NULL() with no actual arguments.
