Disable some image comparison tests on architectures such as i686 where intermediate floating-point operations are done with 80-bit long doubles, and typically later rounded to 64-bit doubles. This double rounding causes small differences in the resulting pixel values compared with other architectures, causing the image comparisons to fail.

Since dependencies specified in ‘.guix-channel’ are usually less specific that those provided by the user, this would lead to the use of instances corresponding to those less specific specs, which in turn might declare dependencies that do not exist for the more specific instances. This commit changes ‘latest-channel-instances’ to perform a breadth-first traversal, thereby giving user-supplied channels higher precedence over dependencies found via ‘.guix-channel’. Fixes <https://issues.guix.gnu.org/68822>. * guix/channels.scm (latest-channel-instances)[ignore?]: Remove. [instance-name, same-named?, more-specific?]: New procedures. Rewrite as a breadth-first traversal using a regular loop. * tests/channels.scm ("latest-channel-instances reads dependencies from most-specific instance"): New test. Change-Id: Iba518145cfd209f04293a56246dbfee3b714650b Ludovic Courtès 2024-01-31channels: Tweak test....* tests/channels.scm ("latest-channel-instances excludes duplicate channel dependencies"): Use ‘equal?’ rather than ‘string=?’ since we can get #f.
