[PATCH] D31953: Use methods to access data stored with frame instructions

[Serge Pavlov via Phabricator via llvm-commits]

sepavloff created this revision.

Instructions CALLSEQ_START..CALLSEQ_END and their target dependent
counterparts keep data like frame size, stack adjustment etc. These
data are accessed by getOperand using hard coded indices. It is
error prone way. This change implements the access by special methods,
which improve readability and allow changing data representation without
massive changes of index values.
This patch is essentially NFC, it is needed to simplify subsequent changes.
