gbtozers 308759bb3b [DebugInfo] Process DBG_VALUE_LIST in LiveDebugVariables ... This patch adds support for DBG_VALUE_LIST in the LiveDebugVariables pass. The changes are mostly in computeIntervals, extendDef, and addDefsFromCopies; when extending the def of a DBG_VALUE_LIST the live ranges of every used register must be considered, and when such a def is killed by more than one of its used registers being killed at the same time it is necessary to find valid copies of all of those registers to create a new def with. The DebugVariableValue class has also been changed to reference multiple location numbers instead of just one. This has been accomplished by using a C-style array with a unique_ptr and an array length packed into 6 bits, to minimize the size of the class (which must be kept low to be used with IntervalMap). This may not be the most efficient solution possible, and should be looked at if performance issues arise. Differential Revision: https://reviews.llvm.org/D83895		2021-03-10 12:37:59 +00:00
