Set architecture to arm in arm-.xml files This patch is to add the following line to various arm target description xml files, <architecture>arm</architecture> 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 <architecture>iwmmxt</architecture>, 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 <yao.qi@linaro.org> * 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 15:58:19 +00:00			`<architecture>arm</architecture>`
