ia64 gcc compile prob

[Todd]

folx,

i've searched archives & the web and can't find reference to this:

i'm getting:

gcc -D__KERNEL__
-I/home/jotto/Cplant/top.10-17/compute/OS/linux-patches/linux-2.4.7/linux/include
-Wall -Wstrict-prototypes -Wno-trigraphs -g -O2 -fomit-frame-pointer
-fno-strict-aliasing -fno-common -pipe  -ffixed-r13
-mfixed-range=f10-f15,f32-f127 -falign-functions=32 -DMODULE   -c -o
scsi_ioctl.o scsi_ioctl.c
scsi_ioctl.c: In function `scsi_ioctl_send_command':
scsi_ioctl.c:366: Internal compiler error in rws_access_regno, at
config/ia64/ia64.c:3689


when trying to compile scsi_ioctl.c on ia64 using

gcc -v
Reading specs from /usr/lib/gcc-lib/ia64-redhat-linux/2.96/specs
gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-81)

on 2.4.7 and 2.4.11 patched with the appropriate patches from ports/ia64.

are there known issues with gcc 2.96 on ia64 and if so, what are the
known slns?  thanks,

It's a compiler bug; fixed in a later release (2.96-9x, 3.0).
Attached is a hack workaround patch.
