|

When @value{GDBN} is debugging the AArch64 architecture, if the Scalable Vector
|
||||
Extension (SVE) is present, then @value{GDBN} will provide the vector registers
|
||||
@code{$z0} through @code{$z31}, vector predicate registers @code{$p0} through
|
||||
@code{$p15}, and the @code{$ffr} register. In addition, the pseudo register
|
||||
@code{$vg} will be provided. This is the vector granule for the current thread
|
||||
and represents the number of 64-bit chunks in an SVE @code{z} register.
|
||||
|
||||
If the vector length changes, then the @code{$vg} register will be updated,
|
||||
but the lengths of the @code{z} and @code{p} registers will not change. This
|
||||
is a known limitation of @value{GDBN} and does not affect the execution of the
|
||||
target process.
