From fe5ddfc3ee21789ec2bdffbe48f6b7cfe730dca7 Mon Sep 17 00:00:00 2001 From: John Baldwin Date: Wed, 16 Sep 2020 11:40:05 -0700 Subject: Assume FreeBSD kernels always report exec events. FreeBSD kernels have reported exec events via the PL_FLAG_EXEC flag since 8.2 release. The most recent release that did not support this flag is 7.4 released in November of 2011. Note that the FreeBSD native target already assumed that PL_FLAG_SCE and PL_FLAG_SCX were always supported on systems supporting PT_LWPINFO, but those flags were added at the same time as PL_FLAG_EXEC. Building the native target on a system without PL_FLAG_EXEC would have failed to build before this change already as a result. gdb/ChangeLog: * fbsd-nat.c (fbsd_nat_target::wait): Always check for PL_FLAG_EXEC. (fbsd_nat_target::insert_exec_catchpoint) (fbsd_nat_target::remove_exec_catchpoint): Always define. * fbsd-nat.h (fbsd_nat_target::insert_exec_catchpoint) (fbsd_nat_target::remove_exec_catchpoint): Always declare. --- gdb/fbsd-nat.c | 7 +------ 1 file changed, 1 insertion(+), 6 deletions(-) (limited to 'gdb/fbsd-nat.c') diff --git a/gdb/fbsd-nat.c b/gdb/fbsd-nat.c index ac88fbc..0ab7f83 100644 --- a/gdb/fbsd-nat.c +++ b/gdb/fbsd-nat.c @@ -1335,7 +1335,6 @@ fbsd_nat_target::wait (ptid_t ptid, struct target_waitstatus *ourstatus, #endif #endif -#ifdef PL_FLAG_EXEC if (pl.pl_flags & PL_FLAG_EXEC) { ourstatus->kind = TARGET_WAITKIND_EXECD; @@ -1343,7 +1342,6 @@ fbsd_nat_target::wait (ptid_t ptid, struct target_waitstatus *ourstatus, = xstrdup (pid_to_exec_file (pid)); return wptid; } -#endif #ifdef USE_SIGTRAP_SIGINFO if (fbsd_handle_debug_trap (this, wptid, pl)) @@ -1508,9 +1506,7 @@ fbsd_nat_target::post_attach (int pid) fbsd_add_threads (this, pid); } -#ifdef PL_FLAG_EXEC -/* If the FreeBSD kernel supports PL_FLAG_EXEC, then traced processes - will always stop after exec. */ +/* Traced processes always stop after exec. */ int fbsd_nat_target::insert_exec_catchpoint (int pid) @@ -1523,7 +1519,6 @@ fbsd_nat_target::remove_exec_catchpoint (int pid) { return 0; } -#endif #ifdef HAVE_STRUCT_PTRACE_LWPINFO_PL_SYSCALL_CODE int -- cgit v1.1
