My apologies if this matter is covered in the manuals or somewhere else
but I have spent hours googling for the solution. I have found many
compliants but no solutions.
I am trying to port an application that uses MMX/SSE to the AMD64
platform and I cannot look at the xmm registers in any way that makes
sense. gdb insists on displaying the values as floats. I know that the
registers that AMD64 uses for x87 and MMX/SSE instructions are the same
but nothing in my program uses floating point math. When looking I get:
(gdb) p /x $xmm4
$9 = {f = {0x0, 0x0, 0x0, 0x0}}
(gdb) p $xmm4
$10 = {f = {4.48415509e-44, 0, 0, 0}}
Is there some way to get the hexi-decimal values of these registers?
Thanks much,
