Quoting for the "which compiler" part: "It used gcc5 to bootstrap as =
there was no clang present and that is the only gcc port installed".

The evidence for this was watching top -PaSCHopid while it worked on the =
installation.

As for the FBSDG5C0 SSD's 11.0-CURRENT history for compilers:

gcc 4.2.1 present.

clang not present.
(Not 3.4.1, not 3.5, not 3.6.
 3.4.1 was lost in the 10.1-STABLE -> 11.0-CURRENT conversion when I did =
delete-old,
 not realizing that I'd end up with no clang at all and no obvious way =
to build one
 on the powerpc64s/powerpcs.)

(None of the below were ever on any 10.1-STABLE SSD as of when I did the =
copies and conversion of some to 11.0-CURRENT.)

powerpc64-xtoolchain-gcc present (and so powerpc64-gcc), installed =
recently for the first time ever. This was the first ever =
not-built-into-world compiler that I've installed on any media. The =
powerpc64-gcc installer has a file naming problem for powerpc64 hosts I =
had to put copies of 5 files that it created under the names it later =
looked for them to finish this install (names not prefixed -> prefixed, =
one file copied to another place).

gcc5 installed just days ago, the second ever ports-compiler installed. =
The install had no problems.



I will note that I have started an installation of lang/clang36 on a =
powerpc (non-64) 11.0-CURRENT that has/had only gcc 4.2.1 and clang =
3.4.1. Watching with top -PaSCHopid shows that it is doing a lang/gcc =
installation as part of its bootstrap, at this point that means 4.8.4.

So it is not using gcc 4.2.1. Again for this SSD there is no history of =
compiler installs other than those that are part of world. clang 3.4.1 =
exists because I did not get around to doing delete-old before I noticed =
that I ended up with no clang as a result. This is the only copy of =
clang 3.4.1 that survived my ignorance to end up on 11.0-CURRENT.

I have another powerpc (non-64) 11.0-CURRENT SSD that does not have =
powerpc64-gcc nor clang but does have gcc5 already. Again gcc5 installed =
in the last few days. Again before the installation there had only ever =
been built-into-world compilers. I've started a lang/CLANG36 install =
here as well.

We will see how each of these goes.



Side note: You can tell I got past the booting/memory-corruption =
problems on the G5 PowerMacs recently (via Powermac specific builds). =
I'm now exploring other things in FreeBSD. :)
