2022-02-10Use functions with prototypes when appropriate; NFCAaron Ballman
A significant number of our tests in C accidentally use functions without prototypes. This patch converts the function signatures to have a prototype for the situations where the test is not specific to K&R C declarations. e.g., void func(); becomes void func(void); This is the seventh batch of tests being updated (there are a significant number of other tests left to be updated).
2020-04-28Improve diagnostics for missing import / #include of module.Richard Smith
Fix a few bugs where we would fail to properly determine header to module correspondence when determining whether to suggest a #include or import, and suggest a #include more often in language modes where there is no import syntax. Generally, if the target is in a header with include guards or #pragma once, we should suggest either #including or importing that header, and not importing a module that happens to textually include it. In passing, improve the notes we attach to the corresponding diagnostics: calling an entity that we couldn't see "previous" is confusing.
2015-06-16[modules] Simplify -cc1 interface for enabling implicit module maps.Richard Smith
We used to have a flag to enable module maps, and two more flags to enable implicit module maps. This is all redundant; we don't need any flag for enabling module maps in the abstract, and we don't usually have -fno- flags for -cc1. We now have just a single flag, -fimplicit-module-maps, that enables implicitly searching the file system for module map files and loading them. The driver interface is unchanged for now. We should probably rename -fmodule-maps to -fimplicit-module-maps at some point. llvm-svn: 239789
2013-08-20During typo correction, check for an exact match in an unimported module. If weRichard Smith
find one, then report the error as a missing import instead of as a typo. llvm-svn: 188821
2013-04-17Extended VerifyDiagnosticConsumer to also verify source file for diagnostic.Andy Gibbs
VerifyDiagnosticConsumer previously would not check that the diagnostic and its matching directive referenced the same source file. Common practice was to create directives that referenced other files but only by line number, and this led to problems such as when the file containing the directive didn't have enough lines to match the location of the diagnostic in the other file, leading to bizarre file formatting and other oddities. This patch causes VerifyDiagnosticConsumer to match source files as well as line numbers. Therefore, a new syntax is made available for directives, for example: // expected-error@file:line {{diagnostic message}} This extends the @line feature where "file" is the file where the diagnostic is generated. The @line syntax is still available and uses the current file for the diagnostic. "file" can be specified either as a relative or absolute path - although the latter has less usefulness, I think! The #include search paths will be used to locate the file and if it is not found an error will be generated. The new check is not optional: if the directive is in a different file to the diagnostic, the file must be specified. Therefore, a number of test-cases have been updated with regard to this. This closes out PR15613. llvm-svn: 179677
2013-02-07Rename -fmodule-cache-path <blah> to -fmodules-cache-path=<blah> for ↵Douglas Gregor
consistency. llvm-svn: 174645
2012-12-11Use @import rather than @__experimental_modules_import, since theDouglas Gregor
latter is rather a mess to type. llvm-svn: 169919
2012-10-12Sanitize the names of modules determined based on the names of headersDouglas Gregor
or directories, to make sure that they are identifiers that are not keywords in any dialect. Fixes <rdar://problem/12489495>. llvm-svn: 165821
2012-03-01Change @import to @__experimental_modules_import. We are not ready to ↵Ted Kremenek
commit to a particular syntax for modules, and don't have time to push it forward in the near future. llvm-svn: 151841
2012-01-03Eliminate the uglified keyword __import_module__ for importingDouglas Gregor
modules. This leaves us without an explicit syntax for importing modules in C/C++, because such a syntax needs to be discussed first. In Objective-C/Objective-C++, the @import syntax is used to import modules. Note that, under -fmodules, C/C++ programs can import modules via the #include mechanism when a module map is in place for that header. This allows us to work with modules in C/C++ without committing to a syntax. llvm-svn: 147467
2012-01-03Rename the command-line option for mapping #include/#import over toDouglas Gregor
module imports from -fauto-module-import to -fmodules. The new name will eventually be used to enable modules, and the #include/#import mapping is a crucial part of the feature. llvm-svn: 147447
2011-12-15Modify how the -verify flag works. Currently, the verification string andRichard Trieu
diagnostic message are compared. If either is a substring of the other, then no error is given. This gives rise to an unexpected case: // expect-error{{candidate function has different number of parameters}} will match the following error messages from Clang: candidate function has different number of parameters (expected 1 but has 2) candidate function has different number of parameters It will also match these other error messages: candidate function function has different number of parameters number of parameters This patch will change so that the verification string must be a substring of the diagnostic message before accepting. Also, all the failing tests from this change have been corrected. Some stats from this cleanup: 87 - removed extra spaces around verification strings 70 - wording updates to diagnostics 40 - extra leading or trailing characters (typos, unmatched parens or quotes) 35 - diagnostic level was included (error:, warning:, or note:) 18 - flag name put in the warning (-Wprotocol) llvm-svn: 146619
2011-12-08Implement umbrella directories for modules, which are similar toDouglas Gregor
umbrella headers in the sense that all of the headers within that directory (and eventually its subdirectories) are considered to be part of the module with that umbrella directory. However, unlike umbrella headers, which are expected to include all of the headers within their subdirectories, Clang will automatically include all of the headers it finds in the named subdirectory. The intent here is to allow a module map to trivially turn a subdirectory into a module, where the module's structure can mimic the directory structure. llvm-svn: 146165
2011-11-29Teach the module import mechanism how to rebuild modules expressed viaDouglas Gregor
module map, rather than assuming that there is an umbrella header. This allows us to automatically build umbrella-less modules. llvm-svn: 145415
2011-11-16A module with an umbrella header assumes that all of the headers inDouglas Gregor
the umbrella header's directory and its subdirectories are part of the module (that's why it's an umbrella). Make sure that these headers are considered to be part of the module for lookup purposes. llvm-svn: 144859
2011-11-16Implement (de-)serialization of the buffer contents for an overriddenDouglas Gregor
file in the source manager. This allows us to properly create and use modules described by module map files without umbrella headers (or with incompletely umbrella headers). More generally, we can actually build a PCH file that makes use of file -> buffer remappings, which could be useful in libclang in the future. llvm-svn: 144830
2011-11-16When building a module from a module map that isn't simply an umbrellaDouglas Gregor
header, create our own in-memory buffer to parse all of the appropriate headers, and use that to build the module. This isn't end-to-end testable yet; that's coming next. llvm-svn: 144797
2011-11-16Add support for building a module from a module map to the -cc1Douglas Gregor
interface. This is currently limited to modules with umbrella headers. llvm-svn: 144736
2011-11-12When searching for a module, speculatively load module maps to see ifDouglas Gregor
the module is described in one of the module maps in a search path or in a subdirectory off the search path that has the same name as the module we're looking for. llvm-svn: 144433
2011-11-11Teach the search for modules to consider modules described by a moduleDouglas Gregor
map, so long as they have an umbrella header. This makes it possible to introduce a module map + umbrella header for a given set of headers, to turn it into a module. There are two major deficiencies here: first, we don't go hunting for module map files when we just see a module import (so we won't know about the modules described therein). Second, we don't yet have a way to build modules that don't have umbrella headers, or have incomplete umbrella headers. llvm-svn: 144424
2011-11-11Wire up the mapping from header files mentioned in module maps over toDouglas Gregor
the corresponding (top-level) modules. This isn't actually useful yet, because we don't yet have a way to build modules out of module maps. llvm-svn: 144410
2011-11-11Introduce basic support for parsing module map files.Douglas Gregor
Module map files provide a way to map between headers and modules, so that we can layer a module system on top of existing headers without changing those headers at all. This commit introduces the module map file parser and the module map that it generates, and wires up the module map file parser so that we'll automatically find module map files as part of header search. Note that we don't yet use the information stored in the module map. llvm-svn: 144402
