This patch introduces tablegen class MCStatement. Currently, an MCStatement can be either a return statement, or a switch statement. ``` MCStatement: MCReturnStatement MCOpcodeSwitchStatement ``` A MCReturnStatement expands to a return statement, and the boolean expression associated with the return statement is described by a MCInstPredicate. An MCOpcodeSwitchStatement is a switch statement where the condition is a check on the machine opcode. It allows the definition of multiple checks, as well as a default case. More details on the grammar implemented by these two new constructs can be found in the diff for TargetInstrPredicates.td. This patch makes it easier to read the body of auto-generated TargetInstrInfo predicates. In future, I plan to reuse/extend the MCStatement grammar to describe more complex target hooks. For now, this is just a first step (mostly a minor cosmetic change to polish the new predicates framework). Differential Revision: https://reviews.llvm.org/D50457 llvm-svn: 339352 |
