From d47f5b30d8481272e9480118bdcb283690070349 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Sat, 2 Jan 2016 09:23:06 -0500 Subject: sim: delete dead current_state globals The global current_state handle to the current simulator state is a design idea that was half implemented, but never really cleaned up. The point was to have a global variable pointing to the state so that funcs could more quickly & easily access the state anywhere. We've instead moved in the direction of passing state around everywhere and don't have any intention of moving back. I also can't find any references to gdb using this variable, or to cgen related "dump_regs" functions, both of which were used in the comments related to this code. --- sim/lm32/sim-if.c | 8 -------- 1 file changed, 8 deletions(-) (limited to 'sim/lm32/sim-if.c') diff --git a/sim/lm32/sim-if.c b/sim/lm32/sim-if.c index 364fc7d..3f65c93 100644 --- a/sim/lm32/sim-if.c +++ b/sim/lm32/sim-if.c @@ -43,10 +43,6 @@ static const OPTION lm32_options[] = { lm32_option_handler}, {{NULL, no_argument, NULL, 0}, '\0', NULL, NULL, NULL} }; - -/* Records simulator descriptor so utilities like lm32_dump_regs can be - called from gdb. */ -SIM_DESC current_state; /* Cover function of sim_state_free to free the cpu buffers as well. */ @@ -240,10 +236,6 @@ sim_open (kind, callback, abfd, argv) Must be done after lm32_cgen_cpu_open. */ cgen_init (sd); - /* Store in a global so things like lm32_dump_regs can be invoked - from the gdb command line. */ - current_state = sd; - return sd; } -- cgit v1.1
