From 1776e3e59ca6200dff981894361b8b49cb453766 Mon Sep 17 00:00:00 2001 From: Nick Alcock Date: Wed, 9 Oct 2019 10:42:00 +0100 Subject: [PATCH] Fix --enable-libctf and --disable-static This fixes test runs and compilation when --disable-libctf, --disable-static, or --enable-shared are passed. Changes since v2: Use GCC_ENABLE and fix indentation. Fix prototype using 'void'. Use 'unsupported' and gdb_caching_proc. Changes since v3: Adapt to upstream changes providing skip_ctf_tests. Changes since v4: Adapt to upstream changes in the seven months (!) since I last looked at this. gdb/ChangeLog * configure.ac: Add --enable-libctf: handle --disable-static properly. * acinclude.m4: sinclude ../config/enable.m4. * Makefile.in (aclocal_m4_deps): Adjust accordingly. (LIBCTF): Substitute in. (CTF_DEPS): New, likewise. (CLIBS): libctf needs symbols from libbfd: move earlier. (CDEPS): Use CTF_DEPS, not LIBCTF, now LIBCTF can include rpath flags. * ctfread.c: Surround in ENABLE_LIBCTF. (elfctf_build_psymtabs) [!ENABLE_LIBCTF]: New stub. * configure: Regenerate. * config.in: Likewise. gdb/testsuite/ChangeLog * configure.ac: Add --enable-libctf. * aclocal.m4: sinclude ../config/enable.m4. * Makefile.in (site.exp): Add enable_libctf to site.exp. * lib/gdb.exp (skip_ctf_tests): Use it. * gdb.base/ctf-constvars.exp: Error message tweak. * gdb.base/ctf-ptype.exp: Likewise. * configure: Regenerate. --- gdb/ChangeLog | 16 ++++++++++ gdb/Makefile.in | 8 +++-- gdb/acinclude.m4 | 3 ++ gdb/config.in | 3 ++ gdb/configure | 40 ++++++++++++++++++++++++ gdb/configure.ac | 21 +++++++++++++ gdb/ctfread.c | 13 ++++++++ gdb/testsuite/ChangeLog | 10 ++++++ gdb/testsuite/Makefile.in | 2 ++ gdb/testsuite/aclocal.m4 | 1 + gdb/testsuite/configure | 18 +++++++++++ gdb/testsuite/configure.ac | 3 ++ gdb/testsuite/gdb.base/ctf-constvars.exp | 2 +- gdb/testsuite/gdb.base/ctf-ptype.exp | 3 +- gdb/testsuite/lib/gdb.exp | 9 +++++- 15 files changed, 146 insertions(+), 6 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index ddb5c47d1e7..d09d316f766 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,19 @@ +2020-06-26 Nick Alcock + + * configure.ac: Add --enable-libctf: handle --disable-static + properly. + * acinclude.m4: sinclude ../config/enable.m4. + * Makefile.in (aclocal_m4_deps): Adjust accordingly. + (LIBCTF): Substitute in. + (CTF_DEPS): New, likewise. + (CLIBS): libctf needs symbols from libbfd: move earlier. + (CDEPS): Use CTF_DEPS, not LIBCTF, now LIBCTF can include rpath + flags. + * ctfread.c: Surround in ENABLE_LIBCTF. + (elfctf_build_psymtabs) [!ENABLE_LIBCTF]: New stub. + * configure: Regenerate. + * config.in: Likewise. + 2020-06-25 Simon Marchi * infcmd.c (set_inferior_io_terminal): Use make_unique_xstrdup. diff --git a/gdb/Makefile.in b/gdb/Makefile.in index 32d0eee7c63..9ae9fe2d1e1 100644 --- a/gdb/Makefile.in +++ b/gdb/Makefile.in @@ -154,7 +154,8 @@ INCLUDE_CFLAGS = -I$(INCLUDE_DIR) LIBIBERTY = ../libiberty/libiberty.a # Where is the CTF library?
