This information is necessary for clients of DebugInfo that do not want to process a DWARF expression, but just treat it as a blob of data. In BOLT, for example, we need to read these expressions in CFIs and write them back to the binary, unchanged, so having access to the original expression encoding is a shortcut to avoid the need to re-encode the entire expression when re-writing exception handling info (CFIs). This patch is an alternative to https://reviews.llvm.org/D98301, in which we implement the support to re-encode these expressions. But since we don't really need to change anything in these expressions, we can just copy their bytes. Reviewed By: aprantl Differential Revision: https://reviews.llvm.org/D107515 |
