It appears that dg-require-alias doesn't report the absence of alias support if
only weak alias support is detected...
# If this target does not support the "alias" attribute, skip this
# test.
proc dg-require-alias { args } {
set alias_available [ check_alias_available ]
if { $alias_available == -1 } {
upvar name name
unresolved "$name"
}
if { $alias_available < 2 } {
upvar dg-do-what dg-do-what
set dg-do-what [list [lindex ${dg-do-what} 0] "N" "P"]
}
}
in lib/target-supports-dg.exp and...
# proc check_alias_available { }
###############################
# Determine if the target toolchain supports the alias attribute.
# Returns 2 if the target supports aliases. Returns 1 if the target
# only supports weak aliased. Returns 0 if the target does not
# support aliases at all. Returns -1 if support for aliases could not
# be determined.
