Evan Cheng ab5c703fdb Fix epilogue codegen to avoid leaving the stack pointer in an invalid ... state. Previously Thumb2 would restore sp from fp like this: mov sp, r7 sub, sp, #4 If an interrupt is taken after the 'mov' but before the 'sub', callee-saved registers might be clobbered by the interrupt handler. Instead, try restoring directly from sp: add sp, #4 Or, if necessary (with VLA, etc.) use a scratch register to compute sp and then restore it: sub.w r4, r7, #8 mov sp, r7 rdar://8465407 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119977 91177308-0d34-0410-b5e6-96231b3b80d8		2010-11-22 18:12:04 +00:00
