The automatic Makefile approach might look something like this. The effect is
similar to what happens when you edit tm.texi.in, except the build would not
be interrupted every time, only when you modify the iterator expansion of a
pattern. There's a new rtx code which can be put into a machine description to
enable this feature.
(No-one else chimed in, so:)
I really like this!
Now that we're in stage1, I thought I'd bring this up again. For
reference, the patch was here:
https://gcc.gnu.org/ml/gcc-patches/2015-12/msg00165.html
So, would you like this for cris and mmix? I could enable it for these,
then we'd need someone to review/approve the generator parts. I'm still
hoping the x86 maintainers would also consider it.
