2010-09-17When emitting a new-expression inside a conditional expression,John McCall
the cleanup might not be dominated by the allocation code. In this case, we have to store aside all the delete arguments in case we need them later. There's room for optimization here in cases where we end up not actually needing the cleanup in different branches (or being able to pop it after the initialization code). Also make sure we only call this operator delete along the path where we actually allocated something. Fixes rdar://problem/8439196. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114145 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-15one piece of code is responsible for the lifetime of every aggregateJohn McCall
slot. The easiest way to do that was to bundle up the information we care about for aggregate slots into a new structure which demands that its creators at least consider the question. I could probably be convinced that the ObjC 'needs GC' bit should be rolled into this structure. Implement generalized copy elision. The main obstacle here is that IR-generation must be much more careful about making sure that exactly git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113962 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-02Abstract IR generation of array cookies into the C++ ABI class andJohn McCall
implement ARM array cookies. Also fix a few unfortunate bugs: - throwing dtors in deletes prevented the allocation from being deleted - adding the cookie to the new[] size was not being considered for overflow (and, more seriously, was screwing up the earlier checks) - deleting an array via a pointer to array of class type was not causing any destructors to be run and was passing the unadjusted pointer to the deallocator - lots of address-space problems, in case anyone wants to support free store in a variant address space :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112814 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-07Store inheritance paths after CastExprs instead of inside them.John McCall
This takes some trickery since CastExpr has subclasses (and indeed, is abstract). Also, smoosh the CastKind into the bitfield from Expr. Drops two words of storage from Expr in the common case of expressions which don't need inheritance paths. Avoids a separate allocation and another word of overhead in cases needing inheritance paths. Also has the advantage of not leaking memory, since destructors for AST nodes are never run. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110507 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-20Follow the implementation approach suggested by PR6687,Chris Lattner
which generates more efficient and more obviously conformant code. We now test for overflow of the multiply then force the result to -1 if so. On X86, this generates nice code like this: __Z4testl: ## @_Z4testl ## BB#0: ## %entry subl $12, %esp movl $4, %eax mull 16(%esp) testl %edx, %edx movl $-1, %ecx cmovel %eax, %ecx movl %ecx, (%esp) call __Znam addl $12, %esp ret git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108927 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-20implement rdar://5739832 - operator new should check for overflow in multiply,Chris Lattner
causing clang to compile this code into something that correctly throws a length error, fixing a potential integer overflow security attack: void *test(long N) { return new int[N]; } int main() { test(1L << 62); } We do this even when exceptions are disabled, because it is better for the code to abort than for the attack to succeed.
