[PATCH] D31604: [DebugInfo][X86] Improve X86 Optimize LEAs handling of debug values.

[Andrew Ng via Phabricator via llvm-commits]

andrewng created this revision.

This is a follow up to the fix in r298360 <https://reviews.llvm.org/rL298360> to improve the handling of debug values when redundant LEAs are removed. The fix in r298360 <https://reviews.llvm.org/rL298360> effectively discarded the debug values. This patch now attempts to preserve the debug values by using the Dwarf 4 DW_OP_stack_value operation.
