Torok Edwin b4bc96317a Fix use-of-uninitialized value when RWX memory can't be allocated (PR6701). ... SELinux doesn't allow 'execmem', returning MAP_FAILED and 'Permission denied' for mmap or RWX memory. In this case AllocateRWX was returning a MemoryBlock with uninitialized fields, which sometimes caused crashes. This patch initializes MemoryBlock fields to 0, so that the RWX-failure check works. It doesn't fix the SELinux 'execmem' issues though (the JIT will not work when SELinux is in enforcing mode). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99762 91177308-0d34-0410-b5e6-96231b3b80d8		2010-03-28 11:07:36 +00:00
