[PATCH 00/11] monitor/hmp: Automatically handle gdb-xml exposed registers

Posted by Philippe Mathieu-Daudé 1 month, 3 weeks ago

MonitorDef registers parsing is one of the oldest APIs in QEMU,
thus predates gdbstub and XML register files. The latters are
maintained by the GDB/binutils project and are more up-to-date.
Getting the target register list from them allows to expose
all accessible registers to the HMP commands.

This series adds gdb_get_register() to monitor to use XML
generated registers, and remove the legacy MonitorDef entries
which became unreachable.

First we need to have the SPARC target better follow the
gdb-xml API.

Philippe Mathieu-Daudé (11):
  target/sparc: Introduce sparc_cpu_register_gdb_regs() stub
  target/sparc: Restore 'gdb-xml/sparc64-cp0.xml'
  target/sparc: Restore 'gdb-xml/sparc64-fpu.xml'
  target/sparc: Restore 'gdb-xml/sparc64-cpu.xml'
  target/sparc: Expose gdbstub registers to sparc32plus target
  target/sparc: Expose gdbstub registers to sparc32 targets
  monitor/hmp: Handle gdb-xml exposed registers via  gdb_get_register()
  target/sparc: Remove MonitorDef register entries available via gdbstub
  target/i386: Remove MonitorDef register entries available via gdbstub
  target/m68k: Remove MonitorDef register entries available via gdbstub
  target/ppc: Remove MonitorDef register entries available via gdbstub
