2009-03-10update this, C headers don't need hacks anymore.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66544 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-10Fix PR3682 by just disabling a broken assertion. This check should beChris Lattner
done in sema, and is reflected by the existing PR3258. In the meantime, fix PR3682 by disabling a bogus assertion (which doesn't account for + operands). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66533 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-10reduce duplication of parsing code between %0 and %x0 andChris Lattner
add support for modifiers on named references, like %c[foo]. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66532 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-10move matching of named operands into AsmStmt class. At the sameChris Lattner
time handle + operands in operand counting, fixing asm.c:t7 to expand into $2 instead of $1. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66531 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-10reduce nesting, use memchr instead of explicit loop, eliminate aChris Lattner
temporary std::string to fix a fixme. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66530 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-10Expand %= into ${:uid} so that the code generator emits a unique ID for theChris Lattner
asm. This allows us to properly handle the case when an optimizer duplicates the asm, such as here: void bar() { int i; for (i = 0; i < 3; ++i) asm("foo %=" : : "r"(0)); } we now produce: _bar: xorl %eax, %eax ## InlineAsm Start foo 0 ## InlineAsm End ## InlineAsm Start foo 1 ## InlineAsm End ## InlineAsm Start foo 2 ## InlineAsm End ret instead of: _bar: xorl %eax, %eax ## InlineAsm Start foo 1 ## InlineAsm End ## InlineAsm Start foo 1 ## InlineAsm End ## InlineAsm Start foo 1 ## InlineAsm End ret This also fixes a fixme by eliminating a static. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66528 91177308-0d34-0410-b5e6-96231b3b80d8

- Group control flow and event PathDiagnosticPieces into PathDiagnosticMacroPieces. - Afterwards, eliminate any PathDiagnosticMacroPieces from a PathDiagnostic that contain no informative events.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66518 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-10Forward -ftemplate-depth-<N> to clang's -ftemplate-depth N.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66516 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-10Limit the template instantiation depth to some user-configurable valueDouglas Gregor
(default: 99). Beyond this limit, produce an error and consider the current template instantiation a failure. The stack we're building to track the instantiations will, eventually, be used to produce instantiation backtraces from diagnostics within template instantiation. However, we're not quite there yet. This adds a new Clang driver option -ftemplate-depth=NNN, which should eventually be generated from the GCC command-line operation -ftemplate-depth-NNN (note the '-' rather than the '='!). I did not make the driver changes to do this mapping. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66513 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-09Backout r66408, we don't want handling of globals to rely on theDaniel Dunbar
module symbol table. The root problem inspiring this was fixed in r66316 (and again in r66506). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66512 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-09Add a test case that goes with the last commitDouglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66510 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-09Implement template instantiation for ClassTemplateSpecializationTypes,Douglas Gregor
such as replacing 'T' in vector<T>. There are a few aspects to this: - Extend TemplateArgument to allow arbitrary expressions (an Expr*), and switch ClassTemplateSpecializationType to store TemplateArguments rather than it's own type-or-expression representation. - ClassTemplateSpecializationType can now store dependent types. In that case, the canonical type is another ClassTemplateSpecializationType (with default template arguments expanded) rather than a declaration (we don't build Decls for dependent types). - Split ActOnClassTemplateId into ActOnClassTemplateId (called from the parser) and CheckClassTemplateId (called from ActOnClassTemplateId and InstantiateType). They're smart enough to handle dependent types, now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66509 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-09NeXT: Move some routines over to CreateMetadataVar.Daniel Dunbar
- No intended functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66473 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-09Fix PR3766, a really nasty silent miscompilation case where we emittedChris Lattner
a warning and then threw away the AST. While I'm in there, tighten up the code to actually reject completely bogus cases (sending a message to a struct). We still allow sending a message to an int, which doesn't make sense but GCC allows it and is easy to support. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66468 91177308-0d34-0410-b5e6-96231b3b80d8
