* Don't allow dllimport variables in constant initializersHans Wennborg2014-06-25
| | | | | | | | | | | | | | | | | This is a follow-up to David's r211677. For the following code, we would end up referring to 'foo' in the initializer for 'arr', and then fail to link, because 'foo' is dllimport and needs to be accessed through the __imp_?foo. __declspec(dllimport) extern const char foo[]; const char* f() { static const char* const arr[] = { foo }; return arr[0]; } Differential Revision: http://reviews.llvm.org/D4299 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211736 91177308-0d34-0410-b5e6-96231b3b80d8

* MS ABI: Propagate class-level DLL attributes to class template ↵Hans Wennborg2014-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | specialization bases (PR11170) Consider the following code: template <typename T> class Base {}; class __declspec(dllexport) class Derived : public Base<int> {} When the base of an exported or imported class is a class template specialization, MSVC will propagate the dll attribute to the base. In the example code, Base<int> becomes a dllexported class. This commit makes Clang do the proopagation when the base hasn't been instantiated yet, and warns about it being unsupported otherwise. This is different from MSVC, which allows changing a specialization back and forth between dllimport and dllexport and seems to let the last one win. Changing the dll attribute after instantiation would be hard for us, and doesn't seem to come up in practice, so I think this is a reasonable limitation to have. MinGW doesn't do this kind of propagation. Differential Revision: http://reviews.llvm.org/D4264 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211725 91177308-0d34-0410-b5e6-96231b3b80d8
* PR20038: DebugInfo: Call sites without DebugLocs for temporary dtors after a ↵David Blaikie2014-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | conditional With && at the top level of an expression, the last thing done when emitting the expression was an unconditional jump to the cleanup block. To reduce the amount of stepping, the DebugLoc is omitted from the unconditional jump. This is done by clearing the IRBuilder's "CurrentDebugLocation"*. If this is not set to some non-empty value before the cleanup block is emitted, the cleanups don't get a location either. If a call without a location is emitted in a function with debug info, and that call is then inlined - bad things happen. (without a location for the call site, the inliner would just leave the inlined DebugLocs as they were - pointing to roots in the original function, not inlined into the current function) Follow up commit to LLVM will ensure that breaking the invariants of the DebugLoc chains by having chains that don't lead to the current function will fail assertions, so we shouldn't accidentally slip any of these cases in anymore. Those assertions may reveal further cases that need to be fixed in clang, though I've tried to test heavily to avoid that. * See r128471, r128513 for the code that clears the CurrentDebugLocation. Simply removing this code or moving the code into IRBuilder to apply to all unconditional branches would regress desired behavior, unfortunately. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211722 91177308-0d34-0410-b5e6-96231b3b80d8

* AST: Initialization with dllimport functions in CDavid Majnemer2014-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The C++ language requires that the address of a function be the same across all translation units. To make __declspec(dllimport) useful, this means that a dllimported function must also obey this rule. MSVC implements this by dynamically querying the import address table located in the linked executable. This means that the address of such a function in C++ is not constant (which violates other rules). However, the C language has no notion of ODR nor does it permit dynamic initialization whatsoever. This requires implementations to _not_ dynamically query the import address table and instead utilize a wrapper function that will be synthesized by the linker which will eventually query the import address table. The effect this has is, to say the least, perplexing. Consider the following C program: __declspec(dllimport) void f(void); typedef void (*fp)(void); static const fp var = &f; const fp fun() { return &f; } int main() { return fun() == var; } MSVC will statically initialize "var" with the address of the wrapper function and "fun" returns the address of the actual imported function. This means that "main" will return false! Note that LLVM's optimizers are strong enough to figure out that "main" should return true. However, this result is dependent on having optimizations enabled! N.B. This change also permits the usage of dllimport declarators inside of template arguments; they are sufficiently constant for such a purpose. Add tests to make sure we don't regress here. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211677 91177308-0d34-0410-b5e6-96231b3b80d8

* Correctly Load Mixed FP-GP Variadic Arguments for x86-64.Rafael Espindola2014-06-24
| | | | | | | | | | | | | | | | | | | | According to the x86-64 ABI, structures with both floating point and integer members are split between floating-point and general purpose registers, and consecutive 32-bit floats can be packed into a single floating point register. In the case of variadic functions these are stored to memory and the position recorded in the va_list. This was already correctly implemented in llvm.va_start.

* Add new debug kind LocTrackingOnly.Diego Novillo2014-06-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This new debug emission kind supports emitting line location information in all instructions, but stops code generation from emitting debug info to the final output. This mode is useful when the backend wants to track source locations during code generation, but it does not want to produce debug info. This is currently used by optimization remarks (-Rpass, -Rpass-missed and -Rpass-analysis). When one of the -Rpass flags is used, the front end will enable location tracking, only if no other debug option is enabled. To prevent debug information from being generated, a new debug info kind LocTrackingOnly causes DIBuilder::createCompileUnit() to not emit the llvm.dbg.cu annotation. This blocks final code generation from generating debug info in the back end. Depends on D4234.
