2012-09-27Add missing function CreateFPCast to the TargetFolder. It's there in the otherNick Lewycky
folders and not having it here fails to compile if you actually try to use it. Also, CreatePointerCast was failing to do the part where it does TD-aware constant folding. Granted there is exactly one case where that it will ever do anything, but there's no reason to skip it. For reference, that case is a subtraction between two constant offsets on the same global variable, eg., "&A[123] - &A[4].f". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164760 91177308-0d34-0410-b5e6-96231b3b80d8

If the offset is more than 24-bits, it won't fit in a scattered relocation offset field, so we fall back to using a non-scattered relocation. rdar://12358909 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164724 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-26Analogous fix to memset and memcpy rewriting. Don't have a test caseChandler Carruth
contrived for these yet, as I spotted them by inspection and the test cases are a bit more tricky to phrase. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164691 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-26When rewriting the pointer operand to a load or store which hasChandler Carruth
alignment guarantees attached, re-compute the alignment so that we consider offsets which impact alignment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164690 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-26Teach all of the loads, stores, memsets and memcpys created by theChandler Carruth
rewriter in SROA to carry a proper alignment. This involves interrogating various sources of alignment, etc. This is a more complete and principled fix to PR13920 as well as related bugs pointed out by Eli in review and by inspection in the area. Also by inspection fix the integer and vector promotion paths to create aligned loads and stores. I still need to work up test cases for these... Sorry for the delay, they were found purely by inspection. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164689 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-26Add some convenience methods to IRBuilder for constructing aligned loadsChandler Carruth
and stores. These will be used in subsequnet patches to SROA to more systematically manage the alignment on loads and stores. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164688 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-26SimplifyCFG: Make the switch-to-lookup table transformation store theHans Wennborg
tables in bitmaps when they fit in a target-legal register. This saves some space, and it also allows for building tables that would otherwise be deemed too sparse. One interesting case that this hits is example 7 from http://blog.regehr.org/archives/320. We currently generate good code for this when lowering the switch to the selection DAG: we build a bitmask to decide whether to jump to one block or the other. My patch will result in the same bitmask, but it removes the need for the jump, as the return value can just be retrieved from the mask. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164684 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-26The assumption that /proc/self/exe always exists is incorrect.Sylvestre Ledru
For example, under a Linux chroot, /proc/ might not be mounted. Therefor, we test if this file exist. If it is the case, use it (the current behavior). Otherwise, we fall back to the detection used by *BSD.
