Writing assebly code for HPUX Itanium ia64

[jonesq]

Hi,

I am having problems on ia64 using cc version 5.50. Basically I am trying to port some old code from PA-Risc architecture on to ia64 IPF. Can anybody point me in the right direction. Below is a small snippet of the assembly code.

Cheers,


*******************SNIP****************************
.EXPORT util_IpMutexTryLock,ENTRY

.CODE

util_IpMutexTryLock
.PROC
.CALLINFO FRAME=0,NO_CALLS
.ENTRY

ldcws 0(0,arg0),%r1
bv %r0(%r2)
copy %r1,ret0

.EXIT
.PROCEND
***************************************************

Hi,
Itanium Assembly is to be viewed not written. Leave that to the compiler.
