From 3ce5b6e25ca2389c545282204b96064c00a13fab Mon Sep 17 00:00:00 2001 From: John Baldwin Date: Sat, 14 Mar 2015 13:47:20 -0400 Subject: [PATCH] Fetch all registers before writing the core register notes. Without this, not all registers were present in the core generated by gcore. For example, running 'gcore' on a program without examining the vector registers (SSE or AVX) would store all the vector registers as zeros because they were not pulled into the regcache. Running 'info vector' before 'gcore' would store the correct values in the core since it populated the regcache. For Linux processes, a similar operation is achieved by having the thread iterator callback invoke target_fetch_registers on each thread before its corresponding register notes are dumped. gdb/ChangeLog: * fbsd-tdep.c (fbsd_make_corefile_notes): Fetch all target registers before writing core register notes. --- gdb/ChangeLog | 5 +++++ gdb/fbsd-tdep.c | 3 ++- 2 files changed, 7 insertions(+), 1 deletion(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index eb8ef879a32..d984565e3f5 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,8 @@ +2015-03-16 John Baldwin + + * fbsd-tdep.c (fbsd_make_corefile_notes): Fetch all target registers + before writing core register notes. + 2015-03-16 Yuanhui Zhang Pedro Alves diff --git a/gdb/fbsd-tdep.c b/gdb/fbsd-tdep.c index 5d17f03caca..9609cd8f8e4 100644 --- a/gdb/fbsd-tdep.c +++ b/gdb/fbsd-tdep.c @@ -89,7 +89,7 @@ fbsd_collect_regset_section_cb (const char *sect_name, int size, static char * fbsd_make_corefile_notes (struct gdbarch *gdbarch, bfd *obfd, int *note_size) { - const struct regcache *regcache = get_current_regcache (); + struct regcache *regcache = get_current_regcache (); char *note_data; Elf_Internal_Ehdr *i_ehdrp; struct fbsd_collect_regset_section_cb_data data; @@ -104,6 +104,7 @@ fbsd_make_corefile_notes (struct gdbarch *gdbarch, bfd *obfd, int *note_size) data.obfd = obfd; data.note_data = NULL; data.note_size = note_size; + target_fetch_registers (regcache, -1); gdbarch_iterate_over_regset_sections (gdbarch, fbsd_collect_regset_section_cb, &data, regcache); -- 2.30.2
