Argyrios Kyrtzidis	fddbcfbec4	Don't waste memory if the initializer expression is empty. llvm-svn: 130420	2011-04-28 18:53:55 +00:00
Argyrios Kyrtzidis	b2ed28ea4b	For double data[20000000] = {0}; we would blow out the memory by creating 20M Exprs to fill out the initializer. To fix this, if the initializer list initializes an array with more elements than there are initializers in the list, have InitListExpr store a single 'ArrayFiller' expression that specifies an expression to be used for value initialization of the rest of the elements. Fixes rdar://9275920. llvm-svn: 129896	2011-04-21 00:27:41 +00:00

For

double data[20000000] = {0};

we would blow out the memory by creating 20M Exprs to fill out the initializer.

To fix this, if the initializer list initializes an array with more elements than
there are initializers in the list, have InitListExpr store a single 'ArrayFiller' expression
that specifies an expression to be used for value initialization of the rest of the elements.

Fixes rdar://9275920.
