Hi, I was wondering, why gimple-match.c and generic-match.c are not built early but always last, which slows down parallel makes significantly. The reason seems to be that generated_files does not mention gimple-match.c and generic-match.c. This comment in Makefile.in says it all: $(ALL_HOST_OBJS) : | $(generated_files) So this patch adds gimple-match.c generic-match.c to generated_files. Tested on x86_64-pc-linux-gnu. Is it OK for trunk? Thanks Bernd. 2021-05-28 Bernd Edlinger * Makefile.in (generated_files): Add gimple-match.c and generic-match.c
