Various
early
versions
of
each
release
of
the
IBM
XLC
compiler
will
not
bootstrap
GNU
CC
.
Symptoms
include
differences
between
the
stage2
and
stage3
object
files
,
and
errors
when
compiling
@
file
{
libgcc
.
a
}
or
@
file
{
enquire
}.
Known
problematic
releases
include
:
xlc
-
1.2.1.8
,
xlc
-
1.3.0.0
(
distributed
with
AIX
3.2.5
),
and
xlc
-
1.3.0.19
.
Both
xlc
-
1.2.1.28
and
xlc
-
1.3.0.24
(
PTF
432238
)
are
known
to
produce
working
versions
of
GNU
CC
,
but
most
other
recent
releases
correctly
bootstrap
GNU
CC
.
Release
4.3.0
of
AIX
and
ones
prior
to
AIX
3.2.4
include
a
version
of
the
IBM
assembler
which
does
not
accept
debugging
directives
:
assembler
updates
are
available
as
PTFs
.
Also
,
if
you
are
using
AIX
3.2.5
or
greater
and
the
GNU
assembler
,
you
must
have
a
version
modified
after
October
16
th
,
1995
in
order
for
the
GNU
C
compiler
to
build
.
See
the
file
@
file
{
README
.
RS6000
}
for
more
details
on
any
of
these
problems
.
GNU
CC
does
not
yet
support
the
64
-
bit
PowerPC
instructions
.
Objective
C
does
not
work
on
this
architecture
because
it
makes
assumptions
that
are
incompatible
with
the
calling
conventions
.
AIX
on
the
RS
/
6000
provides
support
(
NLS
)
for
environments
outside
of
the
United
States
.
Compilers
and
assemblers
use
NLS
to
support
locale
-
specific
representations
of
various
objects
including
floating
-
point
numbers
(
"."
vs
","
for
separating
decimal
fractions
).
There
have
been
problems
reported
where
the
library
linked
with
GNU
CC
does
not
produce
the
same
floating
-
point
formats
that
the
assembler
accepts
.
If
you
have
this
problem
,
set
the
LANG
environment
variable
to
"C"
or
"En_US"
.
Due
to
changes
in
the
way
that
GNU
CC
invokes
the
binder
(
linker
)
for
AIX
4.1
,
you
may
now
receive
warnings
of
duplicate
symbols
from
the
link
step
that
were
not
reported
before
.
The
assembly
files
generated
by
GNU
CC
for
AIX
have
always
included
multiple
symbol
definitions
for
certain
global
variable
and
function
declarations
in
the
original
program
.
The
warnings
should
not
prevent
the
linker
from
producing
a
correct
library
or
runnable
executable
.
By
default
,
AIX
4.1
produces
code
that
can
be
used
on
either
Power
or
PowerPC
processors
.
You
can

a
default
version
for
the
