Subject: [openrisc] [or1ksim #30] Remove `fast sim'

Hi,

As agreed, this removes --enable-fsim.

ChangeLog: * Remove FAST_SIM, it nolonger provides a speed up. nog. -------------- next part -------------- --- configure.in 2005-02-09 18:03:30.000000000 +0100 +++ ../or1ksim-ac/configure.in 2005-02-18 17:30:36.000000000 +0100 @@ -105,17 +105,6 @@ ]) AC_MSG_RESULT(${enable_profiling-no}) -fast_sim="0" -AC_MSG_CHECKING(whether to compile fsim) -AC_ARG_ENABLE(fsim, - [ --enable-fsim compiles fsim, based on fast_config.c], [ - case "$enableval" in - no) fast_sim="0" ;; - yes) fast_sim="1" ;; - esac -]) -AC_MSG_RESULT(${enable_fsim-no}) - simple_execution="0" INCLUDES="-I\${top_builddir}/cpu/$CPU_ARCH" AC_MSG_CHECKING(whether to use simple execution) @@ -173,7 +162,6 @@ ]) AC_MSG_RESULT(${enable_arith_flag-no}) -AC_DEFINE_UNQUOTED(FAST_SIM, $fast_sim) AC_DEFINE_UNQUOTED(RAW_RANGE_STATS, $raw_range_stats) AC_DEFINE_UNQUOTED(SET_OV_FLAG, $set_ov_flag) AC_DEFINE_UNQUOTED(ARITH_SET_FLAG, $set_arith_flag) --- sim-config.h 2005-02-12 10:07:40.000000000 +0100 +++ ../or1ksim-ac/sim-config.h 2005-02-18 17:31:10.000000000 +0100 @@ -250,13 +243,7 @@ } cuc; }; -#if FAST_SIM -#include "fast_config.c" -#define IFF(x) if (x) -#else extern struct config config; -#define IFF(x) if (1) -#endif #define PRINTF(x...) fprintf (runtime.sim.fout, x) --- acconfig.h 2002-05-13 14:58:21.000000000 +0200 +++ ../or1ksim-ac/acconfig.h 2005-02-18 17:32:34.000000000 +0100 @@ -9,9 +9,6 @@ /* Whether the compiler supports 'long long'. */ #define CC_HAS_LONG_LONG -/* Whether we are building fsim */ -#define FAST_SIM 0 - /* Whether we have ethernet PHY support */ #define HAVE_ETH_PHY 0 --- cpu/or32/insnset.c 2005-02-12 12:37:05.000000000 +0100 +++ ../or1ksim-ac/cpu/or32/insnset.c 2005-02-18 17:34:49.000000000 +0100 @@ -64,7 +64,7 @@ } INSTRUCTION (l_sw) { int old_cyc = 0; - IFF (config.cpu.sbuf_len) old_cyc = runtime.sim.mem_cycles; + if (config.cpu.sbuf_len) old_cyc = runtime.sim.mem_cycles; set_mem32(PARAM0, PARAM1, &breakpoint); if (config.cpu.sbuf_len) { int t = runtime.sim.mem_cycles; @@ -74,7 +74,7 @@ } INSTRUCTION (l_sb) { int old_cyc = 0; - IFF (config.cpu.sbuf_len) old_cyc = runtime.sim.mem_cycles; + if (config.cpu.sbuf_len) old_cyc = runtime.sim.mem_cycles; set_mem8(PARAM0, PARAM1, &breakpoint); if (config.cpu.sbuf_len) { int t = runtime.sim.mem_cycles; @@ -84,7 +84,7 @@ } INSTRUCTION (l_sh) { int old_cyc = 0; - IFF (config.cpu.sbuf_len) old_cyc = runtime.sim.mem_cycles; + if (config.cpu.sbuf_len) old_cyc = runtime.sim.mem_cycles; set_mem16(PARAM0, PARAM1, &breakpoint); if (config.cpu.sbuf_len) { int t = runtime.sim.mem_cycles; --- cpu/common/abstract.c 2005-02-12 12:37:05.000000000 +0100 +++ ../or1ksim-ac/cpu/common/abstract.c 2005-02-18 17:36:16.000000000 +0100 @@ -173,17 +173,10 @@ return cur_area; /* When mc is enabled, we must check valid also, otherwise we assume it is nonzero */ - IFF (config.mc.enabled) { - /* Check list of registered devices. */ - for(ptmp = dev_list; ptmp; ptmp = ptmp->next) - if ((addr & ptmp->addr_mask) == (ptmp->addr_compare & ptmp->addr_mask) && ptmp->valid) - return cur_area = ptmp; - } else { - /* Check list of registered devices. */ - for(ptmp = dev_list; ptmp; ptmp = ptmp->next) - if ((addr & ptmp->addr_mask) == (ptmp->addr_compare & ptmp->addr_mask)) - return cur_area = ptmp; - } + /* Check list of registered devices. */ + for(ptmp = dev_list; ptmp; ptmp = ptmp->next) + if ((addr & ptmp->addr_mask) == (ptmp->addr_compare & ptmp->addr_mask) && ptmp->valid) + return cur_area = ptmp; return cur_area = NULL; } --- sim-cmd.c 2005-02-12 12:37:05.000000000 +0100 +++ ../or1ksim-ac/sim-cmd.c 2005-02-18 17:48:01.000000000 +0100 @@ -134,13 +134,11 @@ PRINTF("dv <fromaddr> [<toaddr>] [<modname>] - dumps memory as verilog (use redirect)\n"); PRINTF("dh <fromaddr> [<toaddr>] - dumps memory as hex code (use redirect)\n"); PRINTF("<cmd> > <filename> - redirect simulator stdout to <filename> (and not emulated PRINTF)\n"); -#if !FAST_SIM PRINTF("set <section> <item> = <param> - set configuration.
