Previously we assumed the section name had the form .text$foo, which is what we used to do for inline functions. If the dollar wasn't present, we'd put unwind data in the .pdata and .xdata sections for the main .text section, which is incorrect. Fixes PR22001. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@224738 91177308-0d34-0410-b5e6-96231b3b80d8

// This test ensures functions in custom sections get unwind info emitted in a
|
|
// distinct .xdata section. Ideally we'd just emit a second .xdata section with
|
|
// the same name and characteristics, but MC uniques sections by name and
|
|
// characteristics, so that is not possible.
