------- Comment #11 from jason at gcc dot gnu dot org 2010-03-03 19:05 -------
As fixed as it reasonably can be until we switch to -fabi-version=4. We now
have a new mangling enabled with that flag, an error in the compiler for this
situation, a warning with -Wabi about the old mangling, and
forward-compatibility aliases so that code built with ABI v4 can link against
definitions compiled with ABI v2.

This revised patch bootstraps on x86_64-apple-darwin10 and
eliminates the mangle41.c failures. We are still left with the failures...
FAIL: g++.dg/abi/mangle40.C scan-assembler weak[^\n]*_Z1fIDv4_fEvT_
FAIL: g++.dg/abi/mangle40.C scan-assembler weak[^\n]*_ZN1AIDv4_fE1tE
Does the mangle40.s assembly provide any clues?

Hmm, that's odd. Why would Darwin satisfy dg-require-alias when it doesn't
have ASM_OUTPUT_DEF?

------- Comment #22 from howarth at nitro dot med dot uc dot edu 2010-05-22 04:04 -------
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.
in lib/target-supports.exp.
