Note, there is no limit to the depth of nesting. * A protector is required when the address of a local variable (i.e., stack based variable) is exposed. (E.g., such as through a local whose address is taken as part of the RHS of an assignment or a local whose address is taken as part of a function argument.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173231 91177308-0d34-0410-b5e6-96231b3b80d8 2013-01-23T06:41:41Z Bill Wendling isanbard@gmail.com 2013-01-23T06:41:41Z urn:sha1:114baee1fa017daefad2339c77b45b9ca3d79a41 SSPStrong applies a heuristic to insert stack protectors in these situations: * A Protector is required for functions which contain an array, regardless of type or length. * A Protector is required for functions which contain a structure/union which contains an array, regardless of type or length. Note, there is no limit to the depth of nesting. * A protector is required when the address of a local variable (i.e., stack based variable) is exposed. (E.g., such as through a local whose address is taken as part of the RHS of an assignment or a local whose address is taken as part of a function argument.) This patch implements the SSPString attribute to be equivalent to SSPRequired. This will change in a subsequent patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173230 91177308-0d34-0410-b5e6-96231b3b80d8 2012-08-13T21:32:42Z Bill Wendling isanbard@gmail.com 2012-08-13T21:32:42Z urn:sha1:6de47d611edfb2b0a67a5f7105f82c4b24c1a014 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161792 91177308-0d34-0410-b5e6-96231b3b80d8 2010-07-06T05:20:13Z Eric Christopher echristo@apple.com 2010-07-06T05:20:13Z urn:sha1:7d26218ebe790d216d7e2e39d50ca51cc0a90213 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107641 91177308-0d34-0410-b5e6-96231b3b80d8 2010-07-06T05:18:56Z Eric Christopher echristo@apple.com 2010-07-06T05:18:56Z urn:sha1:f7a0c7bf8bc8318ed28d889c9a56437ab3e91385 registers.
