* ...in light of recent activity related to llvm.memcpy flags. I want toAndrew Trick2013-01-301-0/+5
| | | | | | | | | | | | | | | prevent an llvm developer from mistakenly thinking that just because the intrinsic has volatile flags that volatile operations can be converted to or folded into them. Platforms may rely on volatile loads and stores of natively supported data width to be executed as single instruction. When compiling C, this expectation likely holds for l-values of volatile primitive types with native hardware support, but not necessarily for aggregate types. The frontend upholds these expectations, which are not specified in the IR. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173974 91177308-0d34-0410-b5e6-96231b3b80d8

* Add the heuristic to differentiate SSPStrong from SSPRequired.Bill Wendling2013-01-231-3/+14
| | | | | | | | | | | | | | | | | | | The requirements of the strong heuristic are: * 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.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173231 91177308-0d34-0410-b5e6-96231b3b80d8
* Add the IR attribute 'sspstrong'.Bill Wendling2013-01-231-2/+10
| | | | | | | | | | | | | | | | | | | | | | 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

* docs: Nuke the old release notes.Sean Silva2013-01-201-505/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | This change also removes a bunch of boilerplate and stuffing which made it unnecessarily hard to navigate and see the comparatively miniscule actual content that was added to this document during the 3.2 development period (or maybe even sticking around from earlier releases...). The new organization (a flat list) optimizes for making it easy for people who know about changes to add them to the document. It's completely trivial for anyone with basic knowledge of LLVM to come in later (such as when preparing for the actual release) and cluster any changes into logical groups. However, I have left some comments indicating how to add larger descriptions, if someone is feeling adventurous ;) Hopefully this organization will highlight how little effort is being put into producing accurate, high-quality release notes, prompting a corresponding improvement for the 3.3 release. I have preserved the changes to this document that are not present in the 3.2 release notes. There were only two... I'm pretty sure we've been busier than that... (version control shows +213347/-173656 raw lines just in the LLVM repo since the 3.2 release). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172954 91177308-0d34-0410-b5e6-96231b3b80d8
