Illegal register: "icc" : syntax error with Sun C 5.8 compiler

Question

I wanted to compile my C file with compiler option "cc -c -Xc -mt -fast -xarch=amd64" on Solaris 10 amd64 machine but it failed with following error -
Assembler: abc.c
"/tmp/GAAOBain6", line 819 : Illegal register: "icc"
"/tmp/GAAOBain6", line 819 : Syntax error
Near line: " orq %icc,%r8 ;/ line : 210"
"/tmp/GAAOBain6", line 852 : Illegal register: "icc"
"/tmp/GAAOBain6", line 852 : Syntax error
Near line: " movzwq %icc,%r9 ;/ line : 215"
cc: ube failed for abc.c
*** Error code 2
I am using following sun C compiler -
/SS11/SUNWspro/bin/cc -V
cc: Sun C 5.8 Patch 121016-02 2006/03/31
Do anybody has idea about this issue?
Thanks

Answer 1

Thanks Boris for your help.
My abc.c file is following -
struct struct_1 {
unsigned type:8;
unsigned level:5;
unsigned seen:1;
unsigned pad:2;
unsigned length:16;
void sample (unsigned char type)
struct struct_1 *q;
/*** Allocate and assign pBody here **/
q->type = type;
q->length = type;
==========================================
compiling this file with following option gives the error in Sol-10 amd64 -
/SS11/SUNWspro/bin/cc -c -Xc -mt -fast -xarch=amd64 abc.c
But compiling without "-fast" options work fine.
