Attached is a small patch for 1.4c to get rid of warnings
coming from ia64asm.S.


BTW, the warnings I saw:

ia64asm.S: Assembler messages:
ia64asm.S:80: Warning: Use of 'st8.spill.nta' may violate WAW dependency
'AR[UNAT]{%}, % in 0 - 63' (impliedf)
ia64asm.S:80: Warning: Only the first path encountering the conflict is
reported
ia64asm.S:79: Warning: This is the location of the conflicting usage
ia64asm.S:87: Warning: Use of 'st8.spill.nta' may violate WAW dependency
'AR[UNAT]{%}, % in 0 - 63' (impliedf)
ia64asm.S:87: Warning: Only the first path encountering the conflict is
reported
ia64asm.S:86: Warning: This is the location of the conflicting usage
ia64asm.S:129: Warning: Use of 'st8.spill.nta' may violate WAW dependency
'AR[UNAT]{%}, % in 0 - 63' (impliedf)
ia64asm.S:129: Warning: Only the first path encountering the conflict is
reported
ia64asm.S:128: Warning: This is the location of the conflicting usage


I'm not sure warnings you reported came from ia64asm.S.
