Summary: If a routine with no stack frame makes a sibling call, we need to preserve the stack space check even if the local stack frame is empty, since the call target could be a "no-split" function (in which case the linker needs to be able to fix up the prolog sequence in order to switch to a larger stack). This fixes PR37807. Reviewers: cherry, javed.absar Subscribers: srhines, llvm-commits Differential Revision: https://reviews.llvm.org/D48444 llvm-svn: 335604
