-Hi,
-
-the attached v2 includes Tamar's suggestion of keeping the current
-stdout behavior.  When no output files are passed (via -O) the output
-is written to stdout as before.
-
-Tamar also mentioned off-list that, similar to match.pd, it might make
-sense to balance the partitions in a better way than a fixed number
-of patterns threshold.  That's a good idea but I'd rather do that
-separately as the current approach already helps considerably.
-
-Attached v2 was bootstrapped and regtested on power10, aarch64 and
-x86 are still running.
-Stefan also tested v1 on s390 where the partitioning does not help
-but also doesn't slow anything down.  insn-emit.cc isn't very large
-to begin with on s390.
-
-Regards
- Robin

+Subject: [PATCH] genemit: Split insn-emit.cc into several partitions.
 
 On riscv insn-emit.cc has grown to over 1.2 mio lines of code and
 compiling it takes considerable time.
 Therefore, this patch adjust genemit to create several partitions
-(insn-emit-1.cc to insn-emit-n.cc).  In order to do so it first counts
-the number of available patterns, calculates the number of patterns per
-file and starts a new file whenever that number is reached.
+(insn-emit-1.cc to insn-emit-n.cc).  The available patterns are
+written to the given files in a sequential fashion.
 
 Similar to match.pd a configure option --with-emitinsn-partitions=num
 is introduced that makes the number of partition configurable.
