# Decide which version of the annobin plugin for gcc should be used.
|
||||
# There are two possible versions, one created by the annobin package and one
|
||||
# created by the gcc package. The logic selects the gcc version unless both
|
||||
# have been built by the same version of the compiler. In that case the
|
||||
# annobin version is selected instead.
|
||||
#
|
||||
# The point of all this is that the annobin plugin is very sensitive to
|
||||
# mismatches with the version of gcc that built it. If the plugin is built
|
||||
# by version A of gcc, but then run on version B of gcc, it is possible for
|
||||
# the plugin to misbehave, which then causes problems if gating tests examine
|
||||
# the plugin's output. (This has happened more than once in RHEL...).
|
||||
#
|
||||
# So the plugin is built both by gcc and by the annobin package. This means
|
||||
# that whenever gcc is updated a fresh plugin is built, and the logic below
|
||||
# will select that version. But in order to allow annobin development to
|
||||
# proceed independtently of gcc, the annobin package can also update its
|
||||
# version of the plugin, and the logic will select this new version.
