From 364620bf636a0a961892c9274616f8d5ad85eecc Mon Sep 17 00:00:00 2001 From: Nick Alcock Date: Wed, 19 Jun 2019 12:23:38 +0100 Subject: [PATCH] libctf: dump header offsets into the debugging output This is an essential first piece of info needed to debug both libctf writing and reading problems, and we weren't recording it anywhere! (This is a short-term fix: fairly soon, we will record all of this in a form that outlives ctf_bufopen, and then ctf_dump() will be able to dump it like it can everything else.) libctf/ * ctf-open.c (ctf_bufopen): Dump header offsets into the debugging output. --- libctf/ChangeLog | 5 +++++ libctf/ctf-open.c | 3 +++ 2 files changed, 8 insertions(+) diff --git a/libctf/ChangeLog b/libctf/ChangeLog index 9fd9e6617a5..9ff7cd4146b 100644 --- a/libctf/ChangeLog +++ b/libctf/ChangeLog @@ -1,3 +1,8 @@ +2019-06-19 Nick Alcock + + * ctf-open.c (ctf_bufopen): Dump header offsets into the debugging + output. + 2019-06-19 Nick Alcock * ctf-subr.c (_PAGESIZE): Remove. diff --git a/libctf/ctf-open.c b/libctf/ctf-open.c index b0d3ef62055..df735acb408 100644 --- a/libctf/ctf-open.c +++ b/libctf/ctf-open.c @@ -1275,6 +1275,9 @@ ctf_bufopen (const ctf_sect_t *ctfsect, const ctf_sect_t *symsect, if (foreign_endian) flip_header (&hp); + ctf_dprintf ("header offsets: %x/%x/%x/%x/%x/%x/%x\n", + hp.cth_lbloff, hp.cth_objtoff, hp.cth_funcoff, hp.cth_varoff, + hp.cth_typeoff, hp.cth_stroff, hp.cth_strlen); hdrsz = sizeof (ctf_header_t); size = hp.cth_stroff + hp.cth_strlen; -- 2.30.2
