* ARM: support interrupt attributeTim Northover2013-10-01
| | | | | | | | | | | This function-attribute modifies the callee-saved register list and function epilogue (specifically the return instruction) so that a routine is suitable for use as an interrupt-handler of the specified type without disrupting user-mode applications. rdar://problem/14207019 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191766 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | the GHC calling convention. This is purely academic because GHC calls are always tail calls so the register mask will never be used; however, this change makes the code clearer and brings the ARM implementation of the GHC calling convention in line with the X86 implementation. Also, it might save someone else some time trying to figuring out what is happening... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185592 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix for 5.5 Parameter Passing --> Stage C:Stepan Dyatkovskiy2013-04-22
| | | | | | | | | | | | | | | | | -- C.4 and C.5 statements, when NSAA is not equal to SP. -- C.1.cp statement for VA functions. Note: There are no VFP CPRCs in a variadic procedure. Before this patch "NSAA != 0" means "don't use GPRs anymore ". But there are some exceptions in AAPCS. 1. For non VA function: allocate all VFP regs for CPRC. When all VFPs are allocated CPRCs would be sent to stack, while non CPRCs may be still allocated in GRPs. 2. Check that for VA functions all params uses GPRs and then stack. No exceptions, no CPRCs here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180011 91177308-0d34-0410-b5e6-96231b3b80d8
