You may already know this but your patch set seems to require clang 9.

I get the below compilation error which is probably cause by
https://github.com/llvm/llvm-project/commit/90868bb0584f first being
committed for clang 9 (I run "clang version 7.0.1-8
(tags/RELEASE_701/final)").

In file included from gistutil.c:24:
../../../../src/include/utils/float.h:103:7: error: invalid output
constraint '=(at)ccae' in asm
: "=(at)ccae"(ret), [clobber_reg]"=&x"(clobber_reg)
^
