Currently "cf-core.xml" is sent to GDB when using any m68k flavor. Thing is it uses the "org.gnu.gdb.coldfire.core" feature name and gdb 8.3 then expects a coldfire FPU instead of the default m68881 FPU. This is not OK because the m68881 floats registers are 96 bits wide so it crashes GDB with the following error message: (gdb) target remote localhost:7960 Remote debugging using localhost:7960 warning: Register "fp0" has an unsupported size (96 bits) warning: Register "fp1" has an unsupported size (96 bits) ... Remote 'g' packet reply is too long (expected 148 bytes, got 180 bytes): \ 00000000000[...]0000 With this patch: qemu-system-m68k -M none -cpu m68020 -s -S (gdb) tar rem :1234 Remote debugging using :1234 warning: No executable has been specified and target does not support determining executable automatically.
