Bill Schmidt 37900c5dcb This patch addresses a PPC64 ELF issue with passing parameters consisting of structs having size 3, 5, 6, or 7. Such a struct must be passed and received as right-justified within its register or memory slot. The problem is only present for structs that are passed in registers. Previously, as part of a patch handling all structs of size less than 8, I added logic to rotate the incoming register so that the struct was left- justified prior to storing the whole register. This was incorrect because the address of the parameter had already been adjusted earlier to point to the right-adjusted value in the storage slot. Essentially I had accidentally accounted for the right-adjustment twice. In this patch, I removed the incorrect logic and reorganized the code to make the flow clearer. The removal of the rotates changes the expected code generation, so test case structsinregs.ll has been modified to reflect this. I also added a new test case, jaggedstructs.ll, to demonstrate that structs of these sizes can now be properly received and passed. I've built and tested the code on powerpc64-unknown-linux-gnu with no new regressions. I also ran the GCC compatibility test suite and verified that earlier problems with these structs are now resolved, with no new regressions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166680 91177308-0d34-0410-b5e6-96231b3b80d8		2012-10-25 13:38:09 +00:00
