From c939ffeb8049d10a4585ff49e781b665fcd27544 Mon Sep 17 00:00:00 2001 From: Ron Unrau Date: Thu, 7 May 1998 14:36:42 +0000 Subject: [PATCH] Initial Breakpoint support: * sim-main.h: (struct _sim_cpu): add cur_device field. Define cur_device values, breakpoint value, and SIM_ENGINE_HALT_HOOK * interp.c (sim_open): initialize cur_device * sky-engine.c (engine_run): use cur_device to set current_cpu * sky-libvpe.c (vpecallms_cycle): add check for breakpoint * sky-hardware.h: delete NUMBER_CPUS * sky-hardware.c (attach_devices): create a memory mapped comm area for GDB/SIM interactions misc: * sky-vu.c ({read,write}_vu_misc_reg): do default behavior for unknown regs instead of sim_io_error. MP reg is float (was missing cast). --- sim/mips/interp.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/sim/mips/interp.c b/sim/mips/interp.c index 0e9430ef96..6634d3b8bc 100644 --- a/sim/mips/interp.c +++ b/sim/mips/interp.c @@ -345,8 +345,8 @@ sim_open (kind, cb, abfd, argv) /* start-sanitize-sky */ #if defined(TARGET_SKY) && defined(SKY_FUNIT) - /* Set "--float-type target" as the default. */ - STATE_FP_TYPE_OPT (sd) |= STATE_FP_TYPE_OPT_TARGET; + /* Set "--float-type host" as the default. */ + STATE_FP_TYPE_OPT (sd) &= ~STATE_FP_TYPE_OPT_TARGET; #endif /* end-sanitize-sky */ @@ -474,6 +474,8 @@ sim_open (kind, cb, abfd, argv) /* Finally the VIF registers */ for( rn = 2*NUM_VU_REGS; rn < 2*NUM_VU_REGS + 2*NUM_VIF_REGS; rn++ ) cpu->register_widths[rn + NUM_R5900_REGS] = 32; + + cpu->cur_device = 0; #endif /* end-sanitize-sky */ }
