PP and MM are 4 bytes. - Not supported by all stubs. - - general query qXXXX Request info about XXXX. - general set QXXXX=yyyy Set value of XXXX to yyyy. - query sect offs qOffsets Get section offsets. Reply is - Text=xxx;Data=yyy;Bss=zzz - console output Otext Send text to stdout. Only comes from - remote target. - - Responses can be run-length encoded to save space. A '*' means that - the next character is an ASCII encoding giving a repeat count which - stands for that many repititions of the character preceding the '*'. - The encoding is n+29, yielding a printable character where n >=3 - (which is where rle starts to win). Don't use an n > 126. - - So - "0* " means the same as "0000". */ - -#include "sh7034.h" -#include <string.h> -#include <setjmp.h> -#include <signal.h> - -/* We need to undefine this from the sh7034.h file */ -#undef GBR - -/* Hitachi SH architecture instruction encoding masks */ - -#define COND_BR_MASK 0xff00 -#define UCOND_DBR_MASK 0xe000 -#define UCOND_RBR_MASK 0xf0df -#define TRAPA_MASK 0xff00 - -#define COND_DISP 0x00ff -#define UCOND_DISP 0x0fff -#define UCOND_REG 0x0f00 - -/* Hitachi SH instruction opcodes */ - -#define BF_INSTR 0x8b00 -#define BT_INSTR 0x8900 -#define BRA_INSTR 0xa000 -#define BSR_INSTR 0xb000 -#define JMP_INSTR 0x402b -#define JSR_INSTR 0x400b -#define RTS_INSTR 0x000b -#define RTE_INSTR 0x002b -#define TRAPA_INSTR 0xc300 -#define SSTEP_INSTR 0xc37f - -/* Hitachi SH processor register masks */ - -#define T_BIT_MASK 0x0001 - -/* - * BUFMAX defines the maximum number of characters in inbound/outbound - * buffers.
