Bug #: 14953
Summary: x86 AMD masked/ranged hw breakpoints/watchpoints
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: gdb
AssignedTo: unassigned@sourceware.org
ReportedBy: palves@redhat.com
Classification: Unclassified
Target: x86_64-*-*
From
https://lkml.org/lkml/2012/12/12/261
We see that x86 AMD Family 16h and beyond has support for masked/ranged hw
breakpoints/watchpoints.
GDB has support for such breakpoints with break-range, and masked
watchpoints with 'watch expr [maskvalue]', but HW acceleration
is currently only implemented on PowerPC.
