[PATCH] D48636: [Sparc] Flush register windows for @llvm.returnaddress(1)

[James Y Knight via Phabricator via llvm-commits]

jyknight added inline comments.


================
Comment at: lib/Target/Sparc/SparcISelLowering.cpp:2733
 
+  SDValue Chain = getFLUSHW(Op, DAG);
+
----------------
Maybe pull FLUSHW out of getFRAMEADDR, into LowerFRAMEADDR, so it doesn't get emitted twice here for returnaddress(>= 2) calls?
