New aarch32-linux-nat.c
This patch is to move all the code about transferring regcache <-> byte buffer for arm (aarch32) to a separate file aarch32-linux-nat.c. Then, in the following patch, aarch64 code can use it to do multi-arch debugging. This is a refactory patch. gdb: 2015-07-07 Yao Qi <yao.qi@linaro.org> * aarch32-linux-nat.c: New file. * aarch32-linux-nat.h: New file. * arm-linux-nat.c: Include aarch32-linux-nat.h. (fetch_regs): Move code to aarch32-linux-nat.c. Call aarch32_gp_regcache_supply. (store_regs): Move code to aarch32-linux-nat.c. Call aarch32_gp_regcache_collect. (fetch_vfp_regs): Move code to aarch32-linux-nat.c. Call aarch32_vfp_regcache_supply. (store_vfp_regs): Move code to aarch32-linux-nat.c. Call aarch32_vfp_regcache_collect. * config/arm/linux.mh (NATDEPFILES): Add aarch32-linux-nat.o.
