As I mentioned, in current tr...@1739, my nocona is detected as a
"core2" by config.guess, since it does include lahf.
However, I tried hacking config.guess so that my cpu returns "nocona"
instead --- just because I wanted to benchmark it that way (and also
would be a test of what happens when compiling in nocona w/o lahf).
But now, the configure step fails.
The variables are:
using ABI="64"
CC="gcc -std=gnu99"
CFLAGS="-O2 -m64 -march=nocona -mtune=nocona"
CPPFLAGS=""
MPN_PATH=" x86_64/core2 x86_64 generic"
(so, it seems to be using core2 code, after all...)
The first errors that show up in configure output are:
checking for struct pst_processor.psp_iticksperclktick... no
=yes: command not found: HAVE_NATIVE_%3
=yes: command not found: HAVE_NATIVE_%2
=yes: command not found: HAVE_NATIVE_%3
=yes: command not found: HAVE_NATIVE_%2
And later:
checking size of unsigned short... 0
checking size of unsigned... 0
checking size of unsigned long... 0
checking size of mp_limb_t... 0
configure: error: Oops, mp_limb_t doesn't seem to work
Here it stops...
