*** Problem The documentation for function "getSize" in both MCRegisterClass and TargetRegisterClass states: /// getSize - Return the size of the register in bytes, which is also the size /// of a stack slot allocated to hold a spilled copy of this register. The problem is that these two values are not always the same. For example, H...

Hi everyone, I’m currently playing with the clang driver and I encounter a strange bug. It occurs when I used the getSize function from the SymbolRef class. On iOS, the number returned is not always correct (some function have the right size). Sadly, This is my code (at the end of the main function into driver.cpp) : #### ErrorOr<OwningBinary<Binary>> BinaryOrErr = createBinary(file); if (std::error_...

Example 1: setConstructorS3("ClassA", function(A,x) { if(missing(A))A=15; if(missing(x))x=NA; extend(Object(), "ClassA", .size = A, .x=x ) }) setMethodS3("getSize", "ClassA", function(this,...) { this$.size; }) setMethodS3("getX", "ClassA", function(this,...) { this$.x; }) setConstructorS3("ClassB", function(A,x,bData) { if(missing(bData))bData = NA; extend(ClassA(), "ClassB", .bData = bDat...

Right now we default to returning objects instead of arrays. perl/python have alternates that return tuples/lists. Do we want to %alias those so we can get arrays back or does it really matter?

...to store any valid pointer as the handle at all. It can be literally any value that fits in a 32-bit pointer. Thus we can keep a global variable mapping the GO objects to fake C "pointers" So it would look like this: // The plugin interface. type PluginInterface interface { // Open, GetSize and PRead are required for all plugins. // Other methods are optional. Config(key string, value string) error ConfigComplete() error Open(readonly bool) (PluginConnectionInterface, error) } type PluginConnectionInterface interface { // Open, GetSize and PRead are required for all plug...

...it will fit. You also talked about "It might be even possible to drop the requirement for the size to be known: Replace the call to AtEndOfStream by just trying to read more and checking if it failed, but that is a bit more than I wanted to do for this." That is to remove some calls to getSize()? Is there any expectation that getPointer() will always a pointer within a contiguous region of memory? That is, getPointer() is non-virtual and always refers to the Data field, but the overriding implementation could still dynamically grow some buffer and change Data to point to a new buffer (c...

1. What is the difference between DSNodeHandle and DSNode? What do the functions getLink() and getSize() do? 2. In the previous email, you mentioned that we can use DSNode::getPointerSize() to get the number of links, But I checked the doxygen documentation, there is no such member for DSNode. 3. Previously I use the following code: for( df_iterator<DSNode*> I = df_begin(pnode), E=df_end(pn...

...= SameMemberAccess ? SubobjectTag.getNode() : createAccessTag(CommonType); } MayAlias = SameMemberAccess; return true; } For the 'NewFormat', The 'MayAlias' should be based on overlap of {OffsetInBase, BaseTag.getSize} and {SubobjecTag.getOffset(), SubobjectTag.getSize()} I am not sure if the same holds for the 'GenericTag'.
