David Majnemer	c9911f28e5	[codeview] Correctly handle inlining functions post-dominated by unreachable ... CodeView requires us to accurately describe the extent of the inlined code. We did this by grabbing the next debug location in source order and using *that* to denote where we stopped inlining. However, this is not sufficient or correct in instances where there is no next debug location or the next debug location belongs to the start of another function. To get this correct, use the end symbol of the function to denote the last possible place the inlining could have stopped at. llvm-svn: 259548	2016-02-02 19:22:34 +00:00
Reid Kleckner	1fcd610c94	[codeview] Wire up the .cv_inline_linetable directive ... This directive emits the binary annotations that describe line and code deltas in inlined call sites. Single-stepping through inlined frames in windbg now works. llvm-svn: 259535	2016-02-02 17:41:18 +00:00
David Majnemer	6fcbd7e909	[CodeView] Implement .cv_inline_linetable ... This support is _very_ rudimentary, just enough to get some basic data into the CodeView debug section. Left to do is: - Use the combined opcodes to save space. - Do something about code offsets. llvm-svn: 259230	2016-01-29 19:24:12 +00:00
