Hi Tim,
It seems like building swr forces c++11 mode for the whole build, even
other drivers being built that aren't necessarily ready for it.
Unfortunately c++11 isn't backwards compatible with c++03, so the switch
can't be made unilaterally. Could you have a look at why this is
happening?
An example of something that does this properly is clover, which also
requires c++11 to be built.
Thanks,

Ilia,
Even before SWR was merged and today's isinf fix was commited,
nv50_ir_ra.cpp already has code to make it portable for C++11 (see below).
I honestly don't understand what you're trying to achieve with this
thread...
Are you seriously plan to require C++03 to build nouveau? It would be
insane try to do that once GCC 6 is widely available.
Rather than see you swimming upstream, I much rather see you helping me
helping you to keep nouveau C++11 portable...
Jose
FYI, llvm also forces -std=c++11:
$ llvm-config --cxxflags
-I/usr/lib/llvm-3.6/include -DNDEBUG -D_GNU_SOURCE
-D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS -g
-O2 -fomit-frame-pointer -std=c++11 -fvisibility-inlines-hidden
-fno-exceptions -fPIC -ffunction-sections -fdata-sections -Wcast-qual
and AFAICS configure.ac does not strip it.
