Description Phil Muldoon 2007-08-03 15:33:00 UTC 
These registers exists on an x86_64 platform? If so, support needs to be added
to the ISA, and also to Ptrace.cxx to return the memory for them
Comment 1 Mark Wielaard 2007-08-06 09:50:40 UTC 
The registers (xmm) exist, but they get mapped from register bank 1 (the regular
floating point one) through the IsaX8664. ptrace doesn't seem to support FPXREGS
on x86_64 (it does on x86 since there the FPREGS don't contain the xmm registers
directly).
Comment 2 Phil Muldoon 2008-01-09 13:37:16 UTC 
No. There is not XFP note, all the floating point regisrer data is in the normal
FP note.

	* TestCoredumpAction.java (testGeneralPurposeRegisters): Delete. Replaced by
	frysk.proc.dead.TestCoreRegs.
	(testFloatingPointRegisters): Ditto.
	(testXFloatingPointRegisters): Ditto. 
	* IA32LinuxElfCorefile.java (writeNotePRXFPRegSet): Rewrite and
	use BankRegisters.
	(writeNotePRFPRegSet): Ditto.
	* X8664LinuxElfCorefile.java (writeNotePRFPRegSet): Ditto.
Comment 3 Phil Muldoon 2008-01-09 13:38:30 UTC 
fixed, and closed
