Summary: Multiple is_substr() goals for one CDL item
Product: eCos
Version: 3.0beta1
Platform: Other (please specify)
OS/Version: HostOS: All
Status: ASSIGNED
Severity: normal
Priority: normal
Component: ConfigTool
AssignedTo: john@dallaway.org.uk
ReportedBy: john@dallaway.org.uk

Class: ---
The ConfigTool "Resolve Conflicts" dialog does not cooperate well with the CDL
inference engine in the case of multiple is_substr() goals for a single CDL
item with an existing user_value. For example, the two goals:
requires CYGOPT_USE1 implies is_substr(CYGOPT_EXAMPLE, "substring1")
requires CYGOPT_USE2 implies is_substr(CYGOPT_EXAMPLE, "substring2")
will result in multiple CDL solutions which do not fully resolve the conflict
if CYGOPT_USE1 and CYGOPT_USE2 are enabled at the same time.
This issue is evident when enabling CYGHWR_THUMB for ARM architecture targets.
I will workaround by merging multiple is_substr() expressions into a single
goal for the time being.
