See the -march=nocona There is no mention of nocona in the Makefile. I have an pentium4 CPU without sse3 support. I don't have the sse3 instruction, i.e. Not a nocona arch. Does anyone know how to get fortran to stop using -march=nocona? The sse3 instructions being generated are all: fisttpl 0x17c(%esp) I.e. the fisttpl instruction. Reproducible: Always

I suggest maybe a better fix would be to file: /usr/lib/python2.4/site-packages/numpy/distutils/cpuinfo.py As nocona enables sse3 instructions for nocona, we should do a check for sse3 in the _is_Nocona test routine. --- cpuinfo.py.old 2007-03-04 11:26:20.000000000 +0000 +++ cpuinfo.py 2007-03-04 11:25:14.000000000 +0000 @@ -185,7 +185,7 @@ return self.is_PentiumIV() and self.has_sse3() def _is_Nocona(self): - return self.is_PentiumIV() and self.is_64bit() + return self.is_PentiumIV() and self.is_64bit() and self.has_sse3() def _is_Itanium(self): return re.match(r'.*?Itanium\b',
Which ebuild is this about? Definitely NOT gcc.
Ah! Sorry, if mentioned gfortran, and that is contained in gcc, so I thought it was gcc. It is actually: dev-python/numpy-1.0.1-r1
Thanks.
bicatali: please take care offensichtlich this and set either yourself or the science herd as maintainer.
Thanks for reporting. Should be fixed now with an upstream patch, please re-open if it persists.
