[PATCH] D32205: X86RegisterInfo: eliminateFrameIndex: Force SP in AfterFPPop case; NFC

[Reid Kleckner via Phabricator via llvm-commits]

rnk added inline comments.


================
Comment at: lib/Target/X86/X86RegisterInfo.cpp:679
+  if (AfterFPPop) {
+    assert(!hasBasePointer(MF));
+    assert(!needsStackRealignment(MF));
----------------
Why does this assert hold true? Do we not support tail calls when doing stack realignment?
