Zalathar 6af9fef085 coverage: Emit the filenames section before encoding per-function mappings ... Most coverage metadata is encoded into two sections in the final executable. The `__llvm_covmap` section mostly just contains a list of filenames, while the `__llvm_covfun` section contains encoded coverage maps for each instrumented function. The catch is that each per-function record also needs to contain a hash of the filenames list that it refers to. Historically this was handled by assembling most of the per-function data into a temporary list, then assembling the filenames buffer, then using the filenames hash to emit the per-function data, and then finally emitting the filenames table itself. However, now that we build the filenames table up-front (via a separate traversal of the per-function data), we can hash and emit that part first, and then emit each of the per-function records immediately after building. This removes the awkwardness of having to temporarily store nearly-complete per-function records.		2023-10-22 23:17:15 +11:00
