From: Mike Frysinger Date: Mon, 15 Nov 2021 07:32:06 +0000 (-0500) Subject: sim: split program path out of argv vector X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e8f20a28b1192d746475f045d77ac84411f164df;p=binutils-gdb.git sim: split program path out of argv vector We use the program argv to both find the program to run (argv[0]) and to hold the arguments to the program. Most of the time this is fine, but if we want to let programs specify argv[0] independently (which is possible in standard *NIX programs), this double duty doesn't work. So let's split the path to the program to run out into a separate field by itself. This simplifies the various sim_open funcs too. By itself, this code is more of a logical cleanup than something that is super useful. But it will open up customization of argv[0] in a follow up commit. Split the changes to make it easier to review. --- diff --git a/sim/aarch64/interp.c b/sim/aarch64/interp.c index 18c2fc0eacb..999b949ed88 100644 --- a/sim/aarch64/interp.c +++ b/sim/aarch64/interp.c @@ -339,10 +339,7 @@ sim_open (SIM_OPEN_KIND kind, if (sim_cpu_alloc_all (sd, 1) != SIM_RC_OK || sim_pre_argv_init (sd, argv[0]) != SIM_RC_OK || sim_parse_args (sd, argv) != SIM_RC_OK - || sim_analyze_program (sd, - (STATE_PROG_ARGV (sd) != NULL - ? *STATE_PROG_ARGV (sd) - : NULL), abfd) != SIM_RC_OK + || sim_analyze_program (sd, STATE_PROG_FILE (sd), abfd) != SIM_RC_OK || sim_config (sd) != SIM_RC_OK || sim_post_argv_init (sd) != SIM_RC_OK) { diff --git a/sim/arm/wrapper.c b/sim/arm/wrapper.c index e697d55a6b5..12b974a95f8 100644 --- a/sim/arm/wrapper.c +++ b/sim/arm/wrapper.c @@ -825,10 +825,7 @@ sim_open (SIM_OPEN_KIND kind, } /* Check for/establish the a reference program image. */ - if (sim_analyze_program (sd, - (STATE_PROG_ARGV (sd) != NULL - ? *STATE_PROG_ARGV (sd) - : NULL), abfd) != SIM_RC_OK) + if (sim_analyze_program (sd, STATE_PROG_FILE (sd), abfd) != SIM_RC_OK) { free_state (sd); return 0; diff --git a/sim/avr/interp.c b/sim/avr/interp.c index df7177ef23f..8ec07c98f8d 100644 --- a/sim/avr/interp.c +++ b/sim/avr/interp.c @@ -1710,10 +1710,7 @@ sim_open (SIM_OPEN_KIND kind, host_callback *cb, } /* Check for/establish the a reference program image. */ - if (sim_analyze_program (sd, - (STATE_PROG_ARGV (sd) != NULL - ? *STATE_PROG_ARGV (sd) - : NULL), abfd) != SIM_RC_OK) + if (sim_analyze_program (sd, STATE_PROG_FILE (sd), abfd) != SIM_RC_OK) { free_state (sd); return 0; diff --git a/sim/bfin/interp.c b/sim/bfin/interp.c index fab4df7aaf8..088b5593787 100644 --- a/sim/bfin/interp.c +++ b/sim/bfin/interp.c @@ -740,10 +740,7 @@ sim_open (SIM_OPEN_KIND kind, host_callback *callback, } /* Check for/establish the a reference program image. */ - if (sim_analyze_program (sd, - (STATE_PROG_ARGV (sd) != NULL - ? *STATE_PROG_ARGV (sd) - : NULL), abfd) != SIM_RC_OK) + if (sim_analyze_program (sd, STATE_PROG_FILE (sd), abfd) != SIM_RC_OK) { free_state (sd); return 0; diff --git a/sim/bpf/sim-if.c b/sim/bpf/sim-if.c index aba191df7ec..a8d94411567 100644 --- a/sim/bpf/sim-if.c +++ b/sim/bpf/sim-if.c @@ -147,10 +147,7 @@ sim_open (SIM_OPEN_KIND kind, if (sim_parse_args (sd, argv) != SIM_RC_OK) goto error; - if (sim_analyze_program (sd, - (STATE_PROG_ARGV (sd) != NULL - ? *STATE_PROG_ARGV (sd) - : NULL), abfd) != SIM_RC_OK) + if (sim_analyze_program (sd, STATE_PROG_FILE (sd), abfd) != SIM_RC_OK) goto error; if (sim_config (sd) != SIM_RC_OK) diff --git a/sim/common/nrun.c b/sim/common/nrun.c index 3fd78346f95..f1fb7d12eba 100644 --- a/sim/common/nrun.c +++ b/sim/common/nrun.c @@ -103,7 +103,7 @@ main (int argc, char **argv) if (prog_argv == NULL || *prog_argv == NULL) usage (); - name = *prog_argv; + name = STATE_PROG_FILE (sd); /* For simulators that don't open prog during sim_open() */ if (prog_bfd == NULL) diff --git a/sim/common/sim-base.h b/sim/common/sim-base.h index 674b2d42308..ff54f1d1e4c 100644 --- a/sim/common/sim-base.h +++ b/sim/common/sim-base.h @@ -151,6 +151,11 @@ struct sim_state { const char *model_name; #define STATE_MODEL_NAME(sd) ((sd)->model_name) + /* In standalone simulator, this is the program to run.
