2013-01-26<limits.h> includes <linux/limits.h> on Linux, no need to special-case itDmitri Gribenko1-3/+1
llvm-svn: 173578
2013-01-26Since we're stuck with realpath for the header <-> module mapping,Douglas Gregor1-38/+21
factor the realpath calls into FileManager::getCanonicalName() so we can cache the results of this epically slow operation. 5% speedup on my modules test, and realpath drops out of the profile. llvm-svn: 173542
2013-01-22Fix compilation on Linux, which defines PATH_MAX in a weird place,Douglas Gregor1-0/+5
from Saleem Abdulrasool! llvm-svn: 173208
2013-01-14Infer "link" lines for top-level frameworks. Essentially, a frameworkDouglas Gregor1-0/+30
will have a shared library with the same name as its framework (and no suffix!) within its .framework directory. Detect this both when inferring the whole top-level framework and when parsing a module map. llvm-svn: 172439
2013-01-14Implement parsing, AST, (de-)serialization, and placeholder globalDouglas Gregor1-3/+41
metadata for linking against the libraries/frameworks for imported modules. The module map language is extended with a new "link" directive that specifies what library or framework to link against when a module is imported, e.g., link "clangAST" or link framework "MyFramework" Importing the corresponding module (or any of its submodules) will eventually link against the named library/framework. For now, I've added some placeholder global metadata that encodes the imported libraries/frameworks, so that we can test that this information gets through to the IR. The format of the data is still under discussion. llvm-svn: 172437
2013-01-12Remove useless 'llvm::' qualifier from names like StringRef and others that areDmitri Gribenko1-6/+5
brought into 'clang' namespace by clang/Basic/LLVM.h llvm-svn: 172323
2013-01-10Rework the realpath nonsense for framework lookups to deal moreDouglas Gregor1-5/+22
uniformly with symlinks between top-level and embedded frameworks. llvm-svn: 172030
2013-01-04realpath'ify the mapping from header includes to module imports.Douglas Gregor1-0/+13
llvm-svn: 171516
2012-12-20Revert r170500. It over-zealously converted *ALL* things named Attributes, ↵Bill Wendling1-6/+6
which is wrong here. llvm-svn: 170721
2012-12-19Rename the 'Attributes' class to 'Attribute'. It's going to represent a ↵Bill Wendling1-6/+6
single attribute in the future. llvm-svn: 170500
2012-12-04Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth1-5/+5
uncovered. This required manually correcting all of the incorrect main-module headers I could find, and running the new llvm/utils/sort_includes.py script over the files. I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. llvm-svn: 169237
2012-11-15If an excluded header does not exist, just ignore itDouglas Gregor1-1/+3
llvm-svn: 168077
2012-11-06Remove C++11-isms I just introduced in r167482Douglas Gregor1-3/+3
llvm-svn: 167483
2012-11-06Introduce inferred framework modules into the module map file,Douglas Gregor1-84/+236
allowing a module map to be placed one level above the '.framework' directories to specify that all .frameworks within that directory can be inferred as framework modules. One can also specifically exclude frameworks known not to work. This makes explicit (and more restricted) behavior modules have had "forever", where *any* .framework was assumed to be able to be built as a module. That's not necessarily true, so we white-list directories (with exclusions) when those directories have been audited. llvm-svn: 167482
2012-10-23Make DiagnosticOptions intrusively reference-counted, and make sureDouglas Gregor1-1/+2
the various stakeholders bump up the reference count. In particular, the diagnostics engine now keeps the DiagnosticOptions object alive. llvm-svn: 166508
2012-10-15Teach TargetInfo to hold on to the TargetOptions with which it wasDouglas Gregor1-11/+9
created. llvm-svn: 165943
2012-10-15Introduce the notion of excluded headers into the module mapDouglas Gregor1-30/+46
description. Previously, one could emulate this behavior by placing the header in an always-unavailable submodule, but Argyrios guilted me into expressing this idea properly. llvm-svn: 165921
2012-10-12Sanitize the names of modules determined based on the names of headersDouglas Gregor1-6/+67
or directories, to make sure that they are identifiers that are not keywords in any dialect. Fixes <rdar://problem/12489495>. llvm-svn: 165821
2012-10-05[Modules] Introduce Module::TopHeaders which is a set of top-level headersArgyrios Kyrtzidis1-0/+1
that are associated with a (sub)module. llvm-svn: 165279
2012-09-27Following up on r164620, cope with symlinking from an embeddedDouglas Gregor1-1/+30
framework location out to a top-level framework. Such frameworks are not really embedded at all. llvm-svn: 164774
2012-03-29Make ModuleMapParser own its TargetInfo, so it doesn't get leaked.Benjamin Kramer1-2/+2
llvm-svn: 153648
2012-03-06User-defined literals: reject string and character UDLs in all places where theRichard Smith1-0/+6
grammar requires a string-literal and not a user-defined-string-literal. The two constructs are still represented by the same TokenKind, in order to prevent a combinatorial explosion of different kinds of token. A flag on Token tracks whether a ud-suffix is present, in order to prevent clients from needing to look at the token's spelling. llvm-svn: 152098
2012-02-20Basic: import IntrusiveRefCntPtr<> into clang namespaceDylan Noblesmith1-2/+2
The class name is long enough without the llvm:: added. Also bring in RefCountedBase and RefCountedBaseVPTR. llvm-svn: 150958
2012-02-06Move instantiateTemplateAttribute into the sema namespace, make helpers static.Benjamin Kramer1-1/+2
llvm-svn: 149864
2012-02-05Basic: import SmallString<> into clang namespaceDylan Noblesmith1-6/+6
(I was going to fix the TODO about DenseMap too, but that would break self-host right now. See PR11922.) llvm-svn: 149799
2012-02-02Back out my heinous hack that tricked the module generation mechanismDouglas Gregor1-5/+52
into using non-absolute system includes (<foo>)... ... and introduce another hack that is simultaneously more heineous and more effective. We whitelist Clang-supplied headers that augment or override system headers (such as float.h, stdarg.h, and tgmath.h). For these headers, Clang does not provide a module mapping. Instead, a system-supplied module map can refer to these headers in a system module, and Clang will look both in its own include directory and wherever the system-supplied module map suggests, then adds either or both headers. The end result is that Clang-supplied headers get merged into the system-supplied module for the C standard library. As a drive-by, fix up a few dependencies in the _Builtin_instrinsics module. llvm-svn: 149611
2012-01-30Thread a TargetInfo through to the module map; we'll need it forDouglas Gregor1-3/+10
target-specific module requirements. llvm-svn: 149224
2012-01-27Introduce module attributes into the module map grammar, along with aDouglas Gregor1-7/+101
single attribute ("system") that allows us to mark a module as being a "system" module. Each of the headers that makes up a system module is considered to be a system header, so that we (for example) suppress warnings there. If a module is being inferred for a framework, and that framework directory is within a system frameworks directory, infer it as a system framework. llvm-svn: 149143
2012-01-17Remove unreachable code in Clang. (replace with llvm_unreachable where ↵David Blaikie1-2/+0
appropriate or when GCC requires it) llvm-svn: 148292
2012-01-13Don't infer a submodule for a framework's private header, at least for now.Douglas Gregor1-14/+1
llvm-svn: 148117
2012-01-13Revert previous commit. Something has gone wonky with my local configurationDouglas Gregor1-1/+0
llvm-svn: 148084
2012-01-13When inferring a module map for a framework, add the 'private'Douglas Gregor1-0/+1
requirement to headers under PrivateHeaders. We don't want to build them as part of the module (yet). llvm-svn: 148082
2012-01-06When inferring a submodule ID during module creation, look up theDouglas Gregor1-5/+16
include stack to find the first file that is known to be part of the module. This copes with situations where the module map doesn't completely specify all of the headers that are involved in the module, which can come up when there are very strange #include_next chains (e.g., with weird compiler/stdlib headers like stdarg.h or float.h). llvm-svn: 147662
2012-01-05If we already have a definition for a top-level module that we deserialized ↵Douglas Gregor1-0/+13
from a module file, don't bother parsing a new definition llvm-svn: 147574
2012-01-04Store the submodules of a module in source order, as they are storedDouglas Gregor1-25/+11
in the module map. This provides a bit more predictability for the user, as well as eliminating the need to sort the submodules when serializing them. llvm-svn: 147564
2011-12-31Implement support for module requirements, which indicate the languageDouglas Gregor1-6/+134
features needed for a particular module to be available. This allows mixed-language modules, where certain headers only work under some language variants (e.g., in C++, std.tuple might only be available in C++11 mode). llvm-svn: 147387
2011-12-12Set umbrella directory correctly when we infer a framework moduleDouglas Gregor1-1/+1
llvm-svn: 146451
2011-12-09Implement the notion of umbrella directories, which implicity coverDouglas Gregor1-67/+33
all of the headers below that particular directory. Use umbrella directories as a clean way to deal with (1) directories/frameworks that don't have an umbrella header, but don't want to enumerate all of their headers, and (2) PrivateHeaders, which we never want to enumerate and want to keep separate from the main umbrella header. This also eliminates a little more of the "magic" for private headers, and frameworks in general. llvm-svn: 146235
2011-12-08Implement umbrella directories for modules, which are similar toDouglas Gregor1-10/+73
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
2011-12-08Tweak the syntax of umbrella headers, so that "umbrella" is treated asDouglas Gregor1-101/+36
a modifier for a header declarartion, e.g., umbrella header "headername" Collapse the umbrella-handling code in the parser into the header-handling code, so we don't duplicate the header-search logic. llvm-svn: 146159
2011-12-08Within the module representation, generalize the notion of an umbrellaDouglas Gregor1-7/+7
header to also support umbrella directories. The umbrella directory for an umbrella header is the directory in which the umbrella header resides. No functionality change yet, but it's coming. llvm-svn: 146158
2011-12-08Convert paths to native format before constructing aDouglas Gregor1-5/+12
directory_iterator for them. llvm-svn: 146154
2011-12-07Implement inference for the "Private" submodule corresponding toDouglas Gregor1-5/+51
private headers in a framework. llvm-svn: 146082
2011-12-07Implement basic support for private headers in frameworks. In essence,Douglas Gregor1-20/+108
when we load a module map (module.map) from a directory, also load a private module map (module_private.map) for that directory, if present. That private module map can inject a new submodule that captures private headers. llvm-svn: 146012
2011-12-06Remove misleading error messageDouglas Gregor1-2/+1
llvm-svn: 145958
2011-12-06When inferring a module map for a framework, infer subframeworkDouglas Gregor1-9/+33
modules for each of its subframeworks. llvm-svn: 145957
2011-12-06Allow inferred submodules for any (sub)module that has an umbrella headerDouglas Gregor1-9/+8
llvm-svn: 145945
2011-12-06Implement modules support for subframeworks (aka embeddedDouglas Gregor1-19/+39
frameworks). A submodule can now be labeled as a "framework", and header search will look into the appropriate Headers/PrivateHeaders subdirectories for named headers. llvm-svn: 145941
2011-12-06Minor tweak to prepare for submodules with umbrella headers. No actualDouglas Gregor1-7/+13
functionality change yet. llvm-svn: 145938
2011-12-06Implement inferred submodules support, which (when requested)Douglas Gregor1-30/+92
implicitly generates submodules corresponding to the headers that fall within a module. llvm-svn: 145887
