From: Mike Frysinger Date: Sun, 29 Mar 2015 21:20:37 +0000 (-0400) Subject: sim: mcore/microblaze: delete dead code X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=97eca187b3b286c903d78070736bbe1d95721ec4;p=binutils-gdb.git sim: mcore/microblaze: delete dead code The mcore port had a few structs/defines that were never used. Similarly, the microblaze port, because it was copied from mcore, has that same dead code, and more. The watchpoint logic was never actually used. Punt it all. --- diff --git a/sim/mcore/ChangeLog b/sim/mcore/ChangeLog index 132cda841db..f24032e49fc 100644 --- a/sim/mcore/ChangeLog +++ b/sim/mcore/ChangeLog @@ -1,3 +1,7 @@ +2015-03-29 Mike Frysinger + + * interp.c (struct aout, LONG, SHORT): Delete. + 2015-03-29 Mike Frysinger * Makefile.in (SIM_RUN_OBJS, SIM_EXTRA_CFLAGS, SIM_EXTRA_LIBS): Delete. diff --git a/sim/mcore/interp.c b/sim/mcore/interp.c index 93856d41572..b99988c38fb 100644 --- a/sim/mcore/interp.c +++ b/sim/mcore/interp.c @@ -1779,22 +1779,6 @@ sim_info (SIM_DESC sd, int verbose) #endif } -struct aout -{ - unsigned char sa_machtype[2]; - unsigned char sa_magic[2]; - unsigned char sa_tsize[4]; - unsigned char sa_dsize[4]; - unsigned char sa_bsize[4]; - unsigned char sa_syms[4]; - unsigned char sa_entry[4]; - unsigned char sa_trelo[4]; - unsigned char sa_drelo[4]; -} aout; - -#define LONG(x) (((x)[0]<<24)|((x)[1]<<16)|((x)[2]<<8)|(x)[3]) -#define SHORT(x) (((x)[0]<<8)|(x)[1]) - static void free_state (SIM_DESC sd) { diff --git a/sim/microblaze/ChangeLog b/sim/microblaze/ChangeLog index b2a5150053a..2501423fb1f 100644 --- a/sim/microblaze/ChangeLog +++ b/sim/microblaze/ChangeLog @@ -1,3 +1,13 @@ +2015-03-29 Mike Frysinger + + * interp.c (NUM_ELEM, heap_ptr, stack_ptr, memcycles, struct aout, + LONG, SHORT): Delete. + [WATCHFUNCTIONS]: Delete. + (sim_info) [WATCHFUNCTIONS]: Delete. + (sim_create_inferior): Delete avp, nargs, nenv, s_length, strings, + pointers, and hi_stack. + (sim_do_command): Delete the "watch" command. + 2015-03-29 Mike Frysinger * interp.c (sim_load): Set verbose to 0 when calling sim_load_file. diff --git a/sim/microblaze/interp.c b/sim/microblaze/interp.c index 4e64932c3bf..335181a5aff 100644 --- a/sim/microblaze/interp.c +++ b/sim/microblaze/interp.c @@ -32,14 +32,7 @@ #include "sim-utils.h" #include "microblaze-dis.h" - -#ifndef NUM_ELEM -#define NUM_ELEM(A) (sizeof (A) / sizeof (A)[0]) -#endif - static int target_big_endian = 1; -static unsigned long heap_ptr = 0; -static unsigned long stack_ptr = 0; host_callback *callback; static unsigned long @@ -100,8 +93,6 @@ microblaze_store_unsigned_integer (unsigned char *addr, int len, struct sim_state microblaze_state; -int memcycles = 1; - static SIM_OPEN_KIND sim_kind; static char *myname; @@ -345,24 +336,6 @@ set_initial_gprs (void) CPU.imm_enable = 0; } -#define WATCHFUNCTIONS 1 -#ifdef WATCHFUNCTIONS - -#define MAXWL 80 -word WL[MAXWL]; -char *WLstr[MAXWL]; - -int ENDWL=0; -int WLincyc; -int WLcyc[MAXWL]; -int WLcnts[MAXWL]; -int WLmax[MAXWL]; -int WLmin[MAXWL]; -word WLendpc; -int WLbcyc; -int WLW; -#endif - static int tracing = 0; void @@ -667,55 +640,12 @@ sim_stop (SIM_DESC sd) void sim_info (SIM_DESC sd, int verbose) { -#ifdef WATCHFUNCTIONS - int w, wcyc; -#endif - callback->printf_filtered (callback, "\n\n# instructions executed %10d\n", CPU.insts); callback->printf_filtered (callback, "# cycles %10d\n", (CPU.cycles) ?
