the location should not have changed, nor should have any packaging
(additional files, say).

Graphite support means additional optimizations GCC can perform (if
you specify the respective options).

You need to build the lang/gcc* ports that support Graphite with the
respective option (GRAPHITE) enabled.  It is off by default, and thus
not part of packages.

I am not aware of the FreeBSD packaging system supporting the renaming
of individual files within a package.  You could try to install into a
different location and then tweak things there, I guess.

1st, thanks for your reply. This question was/is stupidly worded :-). 
What I was/am asking is whether the pkg-installed version of this 
compiler is compiled for Graphite support OOTB. The answer appears to be 
'no'. I just pkg-upgraded to the newest version & it is now called 5.3.1:


[29/33] Upgrading gcc5-devel from 5.2.1.s20151124 to 5.3.1.s20151208...
[29/33] Extracting gcc5-devel-5.3.1.s20151208: .. done

However, when queried from the command line, it doesn't mention 'libisl' 
(req'd for Graphite support) & when I try to compile code using Graphite 
optimization (-floop-parallelize-all for me) it fails w/ an error 
message saying Graphite support not available:


f951: sorry, unimplemented: Graphite loop optimizations cannot be used 
(ISL is not available)(-fgraphite, -fgraphite-identity, -floop-block, 
-floop-interchange, -floo
p-strip-mine, -floop-parallelize-all, -floop-unroll-and-jam, and 
-ftree-loop-linear)


libisl is indeed available, pkg installed & ready to go. When I upgraded 
ports (portsnap fetch update) this A.M., nothing got upgraded, 
everything still dated 12/09 or earlier (when I last rebuilt it to turn 
on Graphite support, which apparently worked AOK) except for the log 
files from my compile. The port showed/shows Graphite enabled by default 
(I think). So, another question is whether the pkg & port have different 
build configurations ?






Also, when I did a 'make showconfig', it showed graphite support ready
to go (*yipp*, kudos), but no executable that I could locate on
short notice. Do I still need to compile it up, or is there an
executable ready to go somewhere not-so-obvious to me :-) ?

Graphite support means additional optimizations GCC can perform (if
you specify the respective options).

You need to build the lang/gcc* ports that support Graphite with the
respective option (GRAPHITE) enabled.  It is off by default, and thus
not part of packages.


When I last compiled it up last week, I did a 'make install
FORCE_PKG_REGISTER=1' which overwrote /usr/local/bin/gcc5 (not a huge
issue, but still ), how do I tell it to install the executable under
a different name ? BTW, I am *NOT* particularly familiar w/ the 'GNU
way', so pardon me if this is a bit noobish :-/  TIA & have a good
one.
