are part of the core IR library in order to support dumping and other basic functionality. Rename the 'Assembly' include directory to 'AsmParser' to match the library name and the only functionality left their -- printing has been in the core IR library for quite some time. Update all of the #includes to match. All of this started because I wanted to have the layering in good shape before I started adding support for printing LLVM IR using the new pass infrastructure, and commandline support for the new pass infrastructure. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198688 91177308-0d34-0410-b5e6-96231b3b80d8

|
|
// single entry, multiple exit, region of code that is often hot. Trace-based
|
|
// optimizations treat traces almost like they are a large, strange, basic
|
|
// block: because the trace path is assumed to be hot, optimizations for the
|
|
// fall-through path are made at the expense of the non-fall-through paths.
