Subject: lang/gcc46: .././../gcc-4.6-20121102/gcc/rtl.h:2105:31: error:
use

x_initial_regno_reg_rtx[FIRST_PSEUDO_REGISTER];
On one of my FreeBSD 10-CURRENT boxes (FreeBSD 10.0-CURRENT #3 r242674M:
Tue Nov 6 22:36:47 CET 2012) I get surprisingly the following error
while upgrading the compiler port lang/gcc46.
The bos in question is most recent updated kernel/world sources,
compiled with CLANG and having CLANG set so far as the default compiler
(clang is now cc). The port compiled prior to the switch to CLANG as the
default also with CLANG without problem!
The couriosity is that I also run two other boxes, also the very same
sources for the OS and the most recent updated /usr/ports tree.
Those boxes are modern hardware, Sandy-Bridge and Ivy-Bridge, the
failing box is Core2Duo, I mention this here since I use -O3 and
-march=3Dnative in the compiler options on ALL machines and I also
compil=
e
the sources with option
CXXFLAGS=3D -stdlib=3Dlibc++ -std=3Dc++11
set in /etc/src.conf.
The shwon below error sounds weird, since the other boxes have compiled
the very same day the port lang/gcc has been updated the very same port
without problems.
Since I spread arounf the boxes my /etc/make.conf and /etc/src.conf for
FreeBSD 10.0-CURRENT, I'm very sure that I do not use other flags on the
failing system.
Any ideas?
Regards,
Oliver

I thought it was just me on ia64.
4.7 updated fine:
=== Upgrade of gcc-4.7.3.20121013 to gcc-4.7.3.20121103 complete
