* Merge of the "princeton" branch:Gravatar xleroy2013-06-16
| | | | | | | | | | | | | | - Define type "block" as "positive" instead of "Z". - Strengthen mem_unchanged_on so that the permissions are identical, instead of possibly increasing. - Move mem_unchanged_on from Events to Memory.Mem. - Define it in terms of mem_contents rather than in terms of Mem.load. - ExportClight: try to name temporaries introduced by SimplExpr - SimplExpr: avoid reusing temporaries between different functions, instead, thread a single generator through all functions. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2276 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e

| | | | | | | | | | injections compose (Values, Memdata, Memory) - Memory chunks: Mfloat64 now has alignment 8; introduced Mfloat64al32 that works like old Mfloat64 (i.e. has alignment 4); simplified handling of memcpy builtin accordingly. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1983 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* Strip quotes from section names during #pragma parsing.Gravatar xleroy2012-07-11
