From 08ee7bb982b16742f52cfdc6c649d82ffa2eb177 Mon Sep 17 00:00:00 2001 From: Antonio Borneo Date: Sat, 3 Jul 2021 18:51:20 +0200 Subject: openocd: fix simple cases of NULL comparison There are more than 1000 NULL comparisons to be aligned to the coding style. For recurrent NULL comparison it's preferable using trivial scripts in order to minimize the review effort. Patch generated automatically with the command: sed -i PATTERN $(find src/ -type f) where PATTERN is in the list: 's/(\([a-z][a-z0-9_]*\) == NULL)/(!\1)/g' 's/(\([a-z][a-z0-9_]*->[a-z][a-z0-9_]*\) == NULL)/(!\1)/g' 's/(\([a-z][a-z0-9_]*\.[a-z][a-z0-9_]*\) == NULL)/(!\1)/g' 's/(\([a-z][a-z0-9_]*\) != NULL)/(\1)/g' 's/(\([a-z][a-z0-9_]*->[a-z][a-z0-9_]*\) != NULL)/(\1)/g' 's/(\([a-z][a-z0-9_]*\.[a-z][a-z0-9_]*\) != NULL)/(\1)/g' 's/(NULL == \([a-z][a-z0-9_]*\))/(!\1)/g' 's/(NULL == \([a-z][a-z0-9_]*->[a-z][a-z0-9_]*\))/(!\1)/g' 's/(NULL == \([a-z][a-z0-9_]*\.[a-z][a-z0-9_]*\))/(!\1)/g' 's/(NULL != \([a-z][a-z0-9_]*\))/(\1)/g' 's/(NULL != \([a-z][a-z0-9_]*->[a-z][a-z0-9_]*\))/(\1)/g' 's/(NULL != \([a-z][a-z0-9_]*\.[a-z][a-z0-9_]*\))/(\1)/g' Change-Id: Ida103e325d6d0600fb69c0b7a1557ee969db4417 Signed-off-by: Antonio Borneo Reviewed-on: http://openocd.zylin.com/6350 Tested-by: jenkins --- src/target/aarch64.c | 28 ++++++++++++++-------------- 1 file changed, 14 insertions(+), 14 deletions(-) (limited to 'src/target/aarch64.c') diff --git a/src/target/aarch64.c b/src/target/aarch64.c index 87c6bce..43a13aa 100644 --- a/src/target/aarch64.c +++ b/src/target/aarch64.c @@ -335,7 +335,7 @@ static int aarch64_prepare_halt_smp(struct target *target, bool exc_target, stru LOG_DEBUG("target %s exc %i", target_name(target), exc_target); - while (head != NULL) { + while (head) { struct target *curr = head->target; struct armv8_common *armv8 = target_to_armv8(curr); head = head->next; @@ -359,7 +359,7 @@ static int aarch64_prepare_halt_smp(struct target *target, bool exc_target, stru LOG_DEBUG("target %s prepared", target_name(curr)); - if (first == NULL) + if (!first) first = curr; } @@ -488,7 +488,7 @@ static int update_halt_gdb(struct target *target, enum target_debug_reason debug if (curr->state == TARGET_HALTED) continue; /* remember the gdb_service->target */ - if (curr->gdb_service != NULL) + if (curr->gdb_service) gdb_target = curr->gdb_service->target; /* skip it */ if (curr == gdb_target) @@ -762,7 +762,7 @@ static int aarch64_prep_restart_smp(struct target *target, int handle_breakpoint break; } /* remember the first valid target in the group */ - if (first == NULL) + if (!first) first = curr; } @@ -785,7 +785,7 @@ static int aarch64_step_restart_smp(struct target *target) if (retval != ERROR_OK) return retval; - if (first != NULL) + if (first) retval = aarch64_do_restart_one(first, RESTART_LAZY); if (retval != ERROR_OK) { LOG_DEBUG("error restarting target %s", target_name(first)); @@ -2548,7 +2548,7 @@ static int aarch64_examine_first(struct target *target) uint32_t tmp0, tmp1, tmp2, tmp3; debug = ttypr = cpuid = 0; - if (pc == NULL) + if (!pc) return ERROR_FAIL; if (pc->adiv5_config.ap_num == DP_APSEL_INVALID) { @@ -2634,7 +2634,7 @@ static int aarch64_examine_first(struct target *target) LOG_DEBUG("ttypr = 0x%08" PRIx64, ttypr); LOG_DEBUG("debug = 0x%08" PRIx64, debug); - if (pc->cti == NULL) + if (!pc->cti) return ERROR_FAIL; armv8->cti = pc->cti; @@ -2739,7 +2739,7 @@ static int aarch64_target_create(struct target *target, Jim_Interp *interp) return ERROR_FAIL; aarch64 = calloc(1, sizeof(struct aarch64_common)); - if (aarch64 == NULL) { + if (!aarch64) { LOG_ERROR("Out of memory"); return ERROR_FAIL; } @@ -2797,7 +2797,7 @@ static int aarch64_jim_configure(struct target *target, struct jim_getopt_info * int e; pc = (struct aarch64_private_config *)target->private_config; - if (pc == NULL) { + if (!pc) { pc = calloc(1, sizeof(struct aarch64_private_config)); pc->adiv5_config.ap_num = DP_APSEL_INVALID; target->private_config = pc; @@ -2842,7 +2842,7 @@ static int aarch64_jim_configure(struct target *target, struct jim_getopt_info * if (e != JIM_OK) return e; cti = cti_instance_by_jim_obj(goi->interp, o_cti); - if (cti == NULL) { + if (!cti) { Jim_SetResultString(goi->interp, "CTI name invalid!", -1); return JIM_ERR; } @@ -2896,7 +2896,7 @@ COMMAND_HANDLER(aarch64_handle_disassemble_command) { struct target *target = get_current_target(CMD_CTX); - if (target == NULL) { + if (!target) { LOG_ERROR("No target selected"); return ERROR_FAIL; } @@ -2939,7 +2939,7 @@ COMMAND_HANDLER(aarch64_mask_interrupts_command) if (CMD_ARGC > 0) { n = jim_nvp_name2value_simple(nvp_maskisr_modes, CMD_ARGV[0]); - if (n->name == NULL) { + if (!n->name) { LOG_ERROR("Unknown parameter: %s - should be off or on", CMD_ARGV[0]); return ERROR_COMMAND_SYNTAX_ERROR; } @@ -2971,10 +2971,10 @@ static int jim_mcrmrc(Jim_Interp *interp, int argc, Jim_Obj * const *argv) } context = current_command_context(interp); - assert(context != NULL); + assert(context); target = get_current_target(context); - if (target == NULL) { + if (!target) { LOG_ERROR("%s: no current target", __func__); return JIM_ERR; } -- cgit v1.1
