Description of problem: rpmrc does not enable the instruction sets which are available to some of the listed IA-32 architectures. As a result, generated binaries when compiled for a specific processor are to generic. Selecting -march does schedule for a specific processor, but does not enable the additional instruction sets available, e.g. SSE. A patch for rpmrc.in is attached which adds the options for the instruction sets which are supported by the various IA-32 processor families. Since the default build architecture is a generic one (i386 for IA-32), this will not affect any standard builds. Users building for a specific architecture may benefit from this patch if they override the default buildarchtranslate: in their /etc/rpmrc or ~/.rpmrc file. Version-Release number of selected component (if applicable): # rpm --version RPM version 4.4.2.3 # rpm -q rpm rpm-4.4.2.3-2.fc9.i386 How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:

Created attachment 328660 [details] Optimized IA-32 build options for rpm 4.6.0-0.rc3.1 (FC10) Updates original patch id 312984: "Optimized IA-32 build options" which was made against rpm 4.4.2.3-2 (FC9)
It's redhat-rpm-config which dictates what flags get passed to which archs. Maybe something to look into while we changing the archs for the mass-rebuild...
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle. Changing version to '11'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
This message is a reminder that Fedora 11 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '11'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 11's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 11 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
