Description Steve Snyder 2005-06-27 13:27:57 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050520 Fedora/1.7.8-1.icc

Description of problem:
The gmp-4.1.4-3 package unconditionally builds with 'CFLAGS="-O2 -g -march=pentium4"'.  This creates the potential for the compiler to generate instruction that are not supported on the current system.  Seen on a fully-updated Pentium3 machine.


Version-Release number of selected component (if applicable):
gmp-4.1.4-3

How reproducible:
Always

Steps to Reproduce:
1.Rebuild binary packages or edit gmp.spec.
2.Notice compiler is building with Pentium4 instruction set.
3.
  

Actual Results:  Rebuilt on P3 machine, saw -march=pentium4 on compiler command line.  Yikes!

Expected Results:  Build should respect RPM_OPT_FLAGS.

Seven months and this bug is still New?  I would have guessed that the
generation of potentially illegal instructions merited more attention.

Comment 2 Thomas Woerner 2006-01-26 16:46:45 UTC

Please give an example, when it was built as pentium4?

BTW: Here is an excerpt of the spec file:

# Important for %{ix86}:
# This rpm has to be build on a CPU with sse2 support like Pentium 4 !

The sse2 DSOs gets built additionally to the i386 DSOs.
