+synopsis: Add new non-compilation-affecting options from ghc 9.12
+packages: Cabal
+prs: #10468
+significance:
+
+description: {
+
+- ghc 9.12 adds several new command line options, divided between
+  `LANGUAGE`s (already added), warnings, new preprocessor control options,
+  and compilation control options. Only one of these doesn't affect
+  compilation and has been added to the recomp filters. A second needed
+  to be added to the list of options requiring `Int` parameters.
+
+  The new options, excluding warning and language options, are:
+
+  * `-fexpose-overloaded-unfoldings`
+  * `-fmax-forced-spec-args`
+  * `-fno-expose-overloaded-unfoldings`
+  * `-fobject-determinism`
+  * `-fwrite-if-compression`
+  * `-optCmmP`
+  * `-optJSP`
+  * `-pgmCmmP`
+  * `-pgmJSP`
