From 6b22174ff163b828a2069f22353018ca97fc0fb4 Mon Sep 17 00:00:00 2001 From: Nick Alcock Date: Mon, 3 Jun 2019 14:02:09 +0100 Subject: [PATCH] libctf: look for BSD versus GNU qsort_r signatures We cannot just look for any declaration of qsort_r, because some operating systems have a qsort_r that has a different prototype but which still has a pair of pointers in the right places (the last two args are interchanged): so use AC_LINK_IFELSE to check for both known variants of qsort_r(), and swap their args into a consistent order in a suitable inline function. (The code for this is taken almost unchanged from gnulib.) (Now we are not using AC_LIBOBJ any more, we can use a better name for the qsort_r replacement as well.) libctf/ * qsort_r.c: Rename to... * ctf-qsort_r.c: ... this. (_quicksort): Define to ctf_qsort_r. * ctf-decls.h (qsort_r): Remove. (ctf_qsort_r): Add. (struct ctf_qsort_arg): New, transport the real ARG and COMPAR. (ctf_qsort_compar_thunk): Rearrange the arguments to COMPAR. * Makefile.am (libctf_a_LIBADD): Remove. (libctf_a_SOURCES): New, add ctf-qsort_r.c. * ctf-archive.c (ctf_arc_write): Call ctf_qsort_r, not qsort_r. * ctf-create.c (ctf_update): Likewise. * configure.ac: Check for BSD versus GNU qsort_r signature. * Makefile.in: Regenerate. * config.h.in: Likewise. * configure: Likewise. --- libctf/ChangeLog | 18 ++++ libctf/Makefile.am | 4 +- libctf/Makefile.in | 29 ++--- libctf/config.h.in | 13 ++- libctf/configure | 161 ++++++++++++++++++---------- libctf/configure.ac | 44 +++++++- libctf/ctf-archive.c | 9 +- libctf/ctf-create.c | 2 +- libctf/ctf-decls.h | 39 ++++++- libctf/{qsort_r.c => ctf-qsort_r.c} | 2 +- 10 files changed, 236 insertions(+), 85 deletions(-) rename libctf/{qsort_r.c => ctf-qsort_r.c} (99%) diff --git a/libctf/ChangeLog b/libctf/ChangeLog index 01b8d8da248..c51efea8bcd 100644 --- a/libctf/ChangeLog +++ b/libctf/ChangeLog @@ -1,3 +1,21 @@ +2019-06-04 Nick Alcock + + * qsort_r.c: Rename to... + * ctf-qsort_r.c: ... this. + (_quicksort): Define to ctf_qsort_r. + * ctf-decls.h (qsort_r): Remove. + (ctf_qsort_r): Add. + (struct ctf_qsort_arg): New, transport the real ARG and COMPAR. + (ctf_qsort_compar_thunk): Rearrange the arguments to COMPAR. + * Makefile.am (libctf_a_LIBADD): Remove. + (libctf_a_SOURCES): New, add ctf-qsort_r.c. + * ctf-archive.c (ctf_arc_write): Call ctf_qsort_r, not qsort_r. + * ctf-create.c (ctf_update): Likewise. + * configure.ac: Check for BSD versus GNU qsort_r signature. + * Makefile.in: Regenerate. + * config.h.in: Likewise. + * configure: Likewise. + 2019-06-03 Nick Alcock * ctf-dump.c (ctf_dump_funcs): Free in the right place. diff --git a/libctf/Makefile.am b/libctf/Makefile.am index 49c9f5280a9..926c9919c56 100644 --- a/libctf/Makefile.am +++ b/libctf/Makefile.am @@ -35,4 +35,6 @@ noinst_LIBRARIES = libctf.a libctf_a_SOURCES = ctf-archive.c ctf-dump.c ctf-create.c ctf-decl.c ctf-error.c \ ctf-hash.c ctf-labels.c ctf-lookup.c ctf-open.c ctf-open-bfd.c \ ctf-subr.c ctf-types.c ctf-util.c -libctf_a_LIBADD = $(LIBOBJS) +if NEED_CTF_QSORT_R +libctf_a_SOURCES += ctf-qsort_r.c +endif diff --git a/libctf/Makefile.in b/libctf/Makefile.in index c2cada66167..4fea156c44e 100644 --- a/libctf/Makefile.in +++ b/libctf/Makefile.in @@ -104,6 +104,7 @@ POST_INSTALL = : NORMAL_UNINSTALL = : PRE_UNINSTALL = : POST_UNINSTALL = : +@NEED_CTF_QSORT_R_TRUE@am__append_1 = ctf-qsort_r.c subdir = .
