From 82c40d4b1deb252f2d17ff74f3fae6ae8cdd0383 Mon Sep 17 00:00:00 2001 From: Yao Qi Date: Tue, 7 Jul 2015 16:58:19 +0100 Subject: [PATCH] Set architecture to arm in arm-*.xml files This patch is to add the following line to various arm target description xml files, arm in order to fix problems I've seen on aarch64 multi-arch debugging, detach^M Detaching from program: build-gdb/gdb/testsuite/gdb.base/attach, process 17145^M (gdb) PASS: gdb.base/attach.exp: attach1 detach file^M No executable file now.^M Architecture of file not recognized.^M (gdb) FAIL: gdb.base/attach.exp: attach1, purging symbols after detach Without this patch, struct target_desc *tdesc_* are not initialised properly, that is, fields arch and osabi in 'struct target_desc' are not set properly. This doesn't cause any problems on single arch debugging, because arch-utils.c:gdbarch_info_fill will guess correctly. However, in multi-arch debugging, gdbarch_info_fill gets the aarch64 arch, but the target description is for arm (because the current inferior is 32-bit arm). It is a surprise to me we didn't set architecture to "arm" before in *.xml files, and I didn't find out why didn't do so. AFAICS, gdb/features/arm-with-iwmmxt.xml was added firstly (in patch https://sourceware.org/ml/gdb-patches/2007-01/msg00593.html) which had iwmmxt, however, afterwards, architecture isn't set anymore in features/arm-*.xml files (in patches https://sourceware.org/ml/gdb-patches/2009-07/msg00689.html and https://sourceware.org/ml/gdb-patches/2010-08/msg00225.html). gdb: 2015-07-07 Yao Qi * features/arm-with-m-fpa-layout.xml: Set architecture to arm. * features/arm-with-m-fpa-layout.c: Regenerated. * features/arm-with-m-vfp-d16.xml: Likewise. * features/arm-with-m-vfp-d16.c: Regenerated. * features/arm-with-m.xml: Likewise. * features/arm-with-m.c: Regenerated. * features/arm-with-neon.xml: Likewise. * features/arm-with-neon.c: Regenerated. * features/arm-with-vfpv2.xml: Likewise. * features/arm-with-vfpv2.c: Regenerated. * features/arm-with-vfpv3.xml: Likewise. * features/arm-with-vfpv3.c: Regenerated. --- gdb/ChangeLog | 15 +++++++++++++++ gdb/features/arm-with-m-fpa-layout.c | 2 ++ gdb/features/arm-with-m-fpa-layout.xml | 1 + gdb/features/arm-with-m-vfp-d16.c | 2 ++ gdb/features/arm-with-m-vfp-d16.xml | 1 + gdb/features/arm-with-m.c | 2 ++ gdb/features/arm-with-m.xml | 1 + gdb/features/arm-with-neon.c | 2 ++ gdb/features/arm-with-neon.xml | 1 + gdb/features/arm-with-vfpv2.c | 2 ++ gdb/features/arm-with-vfpv2.xml | 1 + gdb/features/arm-with-vfpv3.c | 2 ++ gdb/features/arm-with-vfpv3.xml | 1 + 13 files changed, 33 insertions(+) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index c1f3994..680f96c 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,5 +1,20 @@ 2015-07-07 Yao Qi + * features/arm-with-m-fpa-layout.xml: Set architecture to arm. + * features/arm-with-m-fpa-layout.c: Regenerated. + * features/arm-with-m-vfp-d16.xml: Likewise. + * features/arm-with-m-vfp-d16.c: Regenerated. + * features/arm-with-m.xml: Likewise. + * features/arm-with-m.c: Regenerated. + * features/arm-with-neon.xml: Likewise. + * features/arm-with-neon.c: Regenerated. + * features/arm-with-vfpv2.xml: Likewise. + * features/arm-with-vfpv2.c: Regenerated. + * features/arm-with-vfpv3.xml: Likewise. + * features/arm-with-vfpv3.c: Regenerated. + +2015-07-07 Yao Qi + * aarch32-linux-nat.h (VFP_REGS_SIZE): New macro, moved from arm-linux-nat.c. * aarch64-linux-nat.c: Include aarch32-linux-nat.h and diff --git a/gdb/features/arm-with-m-fpa-layout.c b/gdb/features/arm-with-m-fpa-layout.c index bc51f05..f720614 100644 --- a/gdb/features/arm-with-m-fpa-layout.c +++ b/gdb/features/arm-with-m-fpa-layout.c @@ -12,6 +12,8 @@ initialize_tdesc_arm_with_m_fpa_layout (void) struct target_desc *result = allocate_target_description ();
