From: "palves at redhat dot com" <sourceware-bugzilla@sourceware.org> To: gdb-prs@sourceware.org Subject: [Bug gdb/10737] catch syscall name mappings (xml) should be per-arch or per-target, not global Date: Fri, 17 Oct 2014 11:44:00 -0000 [thread overview] Message-ID: <bug-10737-4717-Pi2iYM8KKV@http.sourceware.org/bugzilla/> (raw) In-Reply-To: <bug-10737-4717@http.sourceware.org/bugzilla/> https://sourceware.org/bugzilla/show_bug.cgi?id=10737 --- Comment #5 from Pedro Alves <palves at redhat dot com> --- A related question is how to handle syscalls by name ("catch syscall open"): #1 - when the user kills the program, and then starts another one, of a different architecture, in the same inferior. E.g., - file prog64 - start - catch syscall open - kill - file prog32 - run #2 - similarly, when a 64-bit inferior execs a 32-bit inferior. - file prog64 - start - catch syscall open (2 on 64-bit) - continue - inferior execs prog32 - inferior now calls syscall 2, which is something else on i386. These two cases may end up handled by the breakpoint_re_set machinery. #3 - in the presence of multiple inferiors, each with its own arch. - file prog64 - start - add-inferior -exec prog32 - inferior 2 - start - catch syscall open - set schedule-multiple on - c - both inferiors call "open" Here, I don't think we'll catch inferior 1's. syscall catchpoints is presently inferior-specific; while I think it should end up with a location per inferior instead, and "open" should be parsed in each inferior's/location's arch. -- You are receiving this mail because: You are on the CC list for the bug.
