Annotation of GNUtools/cc/README.RS6000, revision 1.1.1.1

1.1       root        1: Specifying the -g flag to GCC on the RS/6000 requires upgrading the
                      2: standard AIX assembler distributed with both AIX 3.1 and AIX 3.2 with
                      3: a replacement that is available from IBM.  The upgraded assembler
                      4: unfortunately was not included in any of the AIX 3.2 update PTF
                      5: releases (3.2.2, 3.2.3, or 3.2.3e).  Note that Makefile.in specifies
                      6: the -g when compiling libgcc2.c.
                      7: 
                      8: You can test for the presense of a fixed assembler by entering the following:
                      9:                % as -u < /dev/null
                     10: If the command exits normally, the assembler fix already is installed.
                     11: If the assembler complains that "-u" is an unknown flag, you need to order
                     12: the fix.
                     13: 
                     14: Any customer can order and get the replacement assembler, and install
                     15: it on one or more machines.  It is distributed both on diskette and
                     16: via VNET (IBM's internal network).  VNET distribution may be desirable
                     17: if you have a friendly IBM rep nearby with networked mainframe access.
                     18: 
                     19: If you are running AIX 3.1.5 or higher (lslpp -h bos.obj output reports
                     20: 03.01.0005.XXXX where the 0005 can be any higher number and the XXXX can be
                     21: any value), call IBM Support at 800-237-5511 and ask for shipment of
                     22: AIX/6000 fix PTF U403044 for APAR IX22829 (.extern foo conflicts with
                     23: defining foo).
                     24: 
                     25: If you are running AIX 3.2 (lslpp -h bos.obj output reports
                     26: 03.02.0000.0000), a newer update to the assembler fix is available.  Ask
                     27: for shipment of AIX/6000 fix PTF U416277 for IX32992 (.global prevents
                     28: detection of duplicate symbol).
                     29: 
                     30: They may also ask you for your customer number.  If you do not know it, you
                     31: will still be able to get the fix, but you will have to be persistent.  IBM
                     32: has corresponding support organizations outside of North America.  Call
                     33: your IBM branch office and ask them to put you in touch with the department
                     34: that handles fixes for AIX/6000.  If that doesn't work, ask for the
                     35: department that handles software defect support for AIX/6000 and ask for
                     36: the APAR fix.
                     37: 
                     38: AIX on the RS/6000 provides support (NLS) for environments outside of
                     39: the United States.  Compilers and assemblers use NLS to support
                     40: locale-specific representations of various objects including
                     41: floating-point numbers ("." vs "," for separating decimal fractions).
                     42: There have been problems reported where the library linked with GCC does
                     43: not produce the same floating-point formats that the assembler accepts.
                     44: If you have this problem, set the LANG environment variable to "C" or
                     45: "En_US".
                     46: 
                     47: XLC version 1.3.0.0 will miscompile jump.c.  XLC version 1.3.0.1 or
                     48: later fixes this problem.  You can obtain XLC-1.3.0.2 by requesting PTF
                     49: 421749 from IBM.
