2010-03-30the big refactoring bits of PR3782.Rafael Espindola
This introduces FunctionType::ExtInfo to hold the calling convention and the noreturn attribute. The next patch will extend it to include the regparm attribute and fix the bug. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99920 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-21Eliminate the default arguments to ASTContext::getFunctionType(),Douglas Gregor
fixing up a few callers that thought they were propagating NoReturn information but were in fact saying something about exception specifications. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96766 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-19More refactoring around constructor/destructor code generation.John McCall
Fix some bugs with function-try-blocks and simplify normal try-block code generation. This implementation excludes a deleting destructor's call to operator delete() from the function-try-block, which I believe is correct but which I can't find straightforward support for at a moment's glance. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96670 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-18Make deleting and complete dtor variants defer to other dtor variants byJohn McCall
calling them as subroutines. This triggers whenever the alias optimization doesn't, i.e. when the dtor has linkonce linkage or there are virtual bases or it's the deleting dtor. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96605 91177308-0d34-0410-b5e6-96231b3b80d8

change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96564 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-16IRgen optimization: cache the value of 'this' and 'vtt' instead ofJohn McCall
repeatedly reloading from an alloca. We still need to create the alloca for debug info purposes (although we currently create it in all cases because of some abstraction boundaries that're hard to break down). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96403 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-09Pass inline keyword to optimizer as the new InlineHint function attribute.Jakob Stoklund Olesen
At the moment the inlinehint attribute is ignored by the Inliner unless you pass a -respect-inlinehint option. This will soon be the default. The inlinehint attribute is set if the inline keyword is explicitly specified on any declaration. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95623 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95525 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-05Standardize the parsing of function type attributes in a way thatJohn McCall
follows (as conservatively as possible) gcc's current behavior: attributes written on return types that don't apply there are applied to the function instead, etc. Only parse CC attributes as type attributes, not as decl attributes; don't accepet noreturn as a decl attribute on ValueDecls, either (it still needs to apply to other decls, like blocks). Consistently consume CC/noreturn information throughout codegen; enforce this by removing their default values in CodeGenTypes::getFunctionInfo(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95436 91177308-0d34-0410-b5e6-96231b3b80d8

if it matches regular name. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93383 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-11Roll out ASTContext::getTypeSizeInChars(), replacing instances ofKen Dyck
"ASTContext::getTypeSize() / 8". Replace [u]int64_t variables with CharUnits ones as appropriate. Also rename RawType, fromRaw(), and getRaw() in CharUnits to QuantityType, fromQuantity(), and getQuantity() for clarity. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93153 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-12Implement runtime checks for undefined behavior. WIP.Mike Stump
This implements a new flag -fcatch-undefined-behavior. The flag turns on additional runtime checks for: T a[I]; a[i] abort when i < 0 or i >= I. Future stuff includes shifts by >= bitwidth amounts. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91198 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-04Make functions returning a struct indirectly evaluate the returned structEli Friedman
directly into the sret pointer. This is an optimization in C, but is required for correctness in C++ for classes with a non-trivial copy constructor. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90526 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02More exception handling improvements... WIP.Mike Stump
Highlights include: Add a helper to generate __cxa_free_exception and _ZSt9terminatev. Add a region to handle EH object deallocation for ctor failures for throw. Add a terminate handler for __cxa_end_catch. A framework for adding cleanup actions for the exceptional edges only. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90305 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-28Implement clang support for indirect branch and address of labelChris Lattner
using the new LLVM support for this. This is temporarily hiding behind horrible and ugly #ifdefs until the time when the optimizer is stable (hopefully a week or so). Until then, lets make it "opt in" :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85446 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-13reimplement codegen for indirect goto with the following advantages:Chris Lattner
1. CGF now has fewer bytes of state (one pointer instead of a vector). 2. The generated code is determinstic, instead of getting labels in 'map order' based on pointer addresses. 3. Clang now emits one 'indirect goto switch' for each function, instead of one for each indirect goto. This fixes an M*N = N^2 IR size issue when there are lots of address-taken labels and lots of indirect gotos. 4. This also makes the default cause do something useful, reducing the size of the jump table needed (by one). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83952 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-13number address-taken labels from 1. This allows 0 to be used as a sentinelChris Lattner
for a null pointer. In other words, "&&foo != NULL" will always work out to true. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83948 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-13Use the new Type::getInt8PtrTy method. This should probably be used in a lotChris Lattner
more places in clang codegen now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83947 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-01CodeGen may see out-of-line declarations of the various special memberDouglas Gregor
functions when they are explicitly declared, e.g., via a function template specialization or explicit template instantiation declaration. Don't try to synthesize bodies for the special member functions in this case; rather, check whether we have an implicit declaration and, if so, synthesize the appropriate function body. Fixes PR5084. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83212 91177308-0d34-0410-b5e6-96231b3b80d8
