[PATCH] D11933: Extending debug ranges

[Vikram TV via llvm-commits]

tvvikram updated this revision to Diff 32399.
tvvikram added a comment.

This patch has the following changes over the previous one:

a. Renamed DebugValueFixup pass as ExtendDebugRangeLocation pass.

b. Improved removal of redundant DBG_VALUE instructions. Added a test case for the same - redundant-dbg_val.ll

c. Add "STATISTIC" to count the number of DBG_VALUE instructions inserted/deleted. I am not sure what benchmarks to exactly test.

d. Updated the test case extend-debug-range.ll to compare against assembly instead of machine instructions. I am getting an error in using MIR serialization, I can send a new patch containing the two new MIR test cases once it works.
