[PATCH] D154281: [CodeGen] Store SP adjustment in MachineBasicBlock. NFCI.

[Jay Foad via Phabricator via llvm-commits]

foad added inline comments.


================
Comment at: llvm/include/llvm/CodeGen/MachineBasicBlock.h:118
+  /// blocks are split in the middle of a call sequence.
+  int SPAdjustment = 0;
+
----------------
On 64-bit hosts this fills a hole in the struct so does not increase the size of `MachineBasicBlock`.
