[llvm-commits] Patch: Fast-math flags for intrinsics

[Michael Ilseman]

Attached are patches for fast-math support for IntrinsicInst. This includes bitcode changes to separate out IntrinsicInsts from CallInsts.

First patch:

Helper functions and minor refactoring. 

Added explicit const to unchanged record reference for API clarity. Added helper functions for the reading and setting of fast-math flags and call arguments. Cleaned up the include lines.


Second Patch: 

Intrinsic support for fast-math flags.

Previously, IntrinsicInsts were handled as CallInsts. However, intrinsics can now have fast-math flags, and thus merit a separate bitcode encoding. This change adds FUNC_CODE_INST_INTRINSIC for intrinsic calls, separates them out from general calls, and adds encoding and decoding of fast-math flags. Backwards compatibility is retained. Adds parsing fast-math flags for IntrinsicInsts, and more tests.
