[Linux-ia64] Back to the future: which gcc for kernel 2.4.18 ?

[Xavier Bru <Xavier.Bru@bull.net>]

Hello,

Building kernel 2.4.18 for ia64 with gcc version 2.96 20000731 , it
seems that there is some problem with code generation in the 
ia64_log_rec_header_print() routine that prints MCA informations:
year appears to be 18002 :-)

Looking at the code with gdb, it seems that the generated code uses
the f6 register without ininitializing:
...
0xe0000000044351f1 <ia64_log_rec_header_print+337>:	xmpy.l f6=f6,f7
...

+BEGIN HARDWARE ERROR STATE AT MCA
SAL RECORD HEADER:  Record buffer = e000000000007000,  header size = 40
e000000000007000 00 00 00 00 98 70 c5 04 02 00 01 00 28 07 00 00 
e000000000007010 48 04 14 00 05 06 02 20 50 6c 61 74 66 6f 72 6d 
e000000000007020 20 69 64 2d 20 4f 45 4d 
Total record length = 1832
End of SAL RECORD HEADER
+Err Record ID: 0    SAL Rev:  0.02
+Time: 06/05/18002/ 14:04:48    Severity 1
             XXXXX

I tried using gcc3 (gcc version 3.0.2 20010905), but I get an internal 
compiler error when I build the kernel.

smpboot.o smpboot.c
smpboot.c: In function `smp_callin':
smpboot.c:370: Internal compiler error in itanium_reorder, at config/ia64/ia64.c:5652
Please submit a full bug report,
with preprocessed source if appropriate.
