From bcc0c096d5b0f77482cdb3154acd2515a0ca832f Mon Sep 17 00:00:00 2001 From: Simon Marchi Date: Mon, 20 Mar 2017 17:37:36 -0400 Subject: Use ptid from regcache in almost all remaining nat files This patch contains almost all of the remaining changes needed to make to_fetch_registers/to_store_registers/to_prepare_to_store independent of inferior_ptid. It contains only some "trivial" changes, the more complicated ones are in separate patches. gdb/ChangeLog: * i386-linux-nat.c (fetch_register, store_register, i386_linux_fetch_inferior_registers, i386_linux_store_inferior_registers): Use ptid from regcache. * ia64-linux-nat.c (ia64_linux_fetch_register, ia64_linux_store_register): Likewise. * inf-ptrace.c (inf_ptrace_fetch_register, inf_ptrace_store_register): Likewise. * m32r-linux-nat.c (m32r_linux_fetch_inferior_registers, m32r_linux_store_inferior_registers): Likewise. * m68k-bsd-nat.c (m68kbsd_fetch_inferior_registers, m68kbsd_store_inferior_registers): Likewise. * m68k-linux-nat.c (fetch_register, store_register, m68k_linux_fetch_inferior_registers, m68k_linux_store_inferior_registers): Likewise. * m88k-bsd-nat.c (m88kbsd_fetch_inferior_registers, m88kbsd_store_inferior_registers): Likewise. * mips-fbsd-nat.c (mips_fbsd_fetch_inferior_registers, mips_fbsd_store_inferior_registers): Likewise. * mips-linux-nat.c (mips64_linux_regsets_fetch_registers, mips64_linux_regsets_store_registers): Likewise. * mips-nbsd-nat.c (mipsnbsd_fetch_inferior_registers, mipsnbsd_store_inferior_registers): Likewise. * mips-obsd-nat.c (mips64obsd_fetch_inferior_registers, mips64obsd_store_inferior_registers): Likewise. * nto-procfs.c (procfs_fetch_registers, procfs_store_registers): Likewise. * ppc-fbsd-nat.c (ppcfbsd_fetch_inferior_registers, ppcfbsd_store_inferior_registers): Likewise. * ppc-linux-nat.c (ppc_linux_fetch_inferior_registers, ppc_linux_store_inferior_registers): Likewise. * ppc-nbsd-nat.c (ppcnbsd_fetch_inferior_registers, ppcnbsd_store_inferior_registers): Likewise. * ppc-obsd-nat.c (ppcobsd_fetch_registers, ppcobsd_store_registers): Likewise. * procfs.c (procfs_fetch_registers, procfs_store_registers): Likewise. * ravenscar-thread.c (ravenscar_fetch_registers, ravenscar_store_registers, ravenscar_prepare_to_store): Likewise. * record-btrace.c (record_btrace_fetch_registers, record_btrace_store_registers, record_btrace_prepare_to_store): Likewise. * remote-sim.c (gdbsim_fetch_register, gdbsim_store_register): Lookup inferior using ptid from regcache, instead of current_inferior. * remote.c (remote_fetch_registers, remote_store_registers): Use ptid from regcache. * rs6000-nat.c (fetch_register, store_register): Likewise. * s390-linux-nat.c (s390_linux_fetch_inferior_registers, s390_linux_store_inferior_registers): Likewise. * sh-nbsd-nat.c (shnbsd_fetch_inferior_registers, shnbsd_store_inferior_registers): Likewise. * sol-thread.c (sol_thread_fetch_registers, sol_thread_store_registers): Likewise. * sparc-nat.c (sparc_fetch_inferior_registers, sparc_store_inferior_registers): Likewise. * tilegx-linux-nat.c (fetch_inferior_registers, store_inferior_registers): Likewise. * vax-bsd-nat.c (vaxbsd_fetch_inferior_registers, vaxbsd_store_inferior_registers): Likewise. * xtensa-linux-nat.c (fetch_gregs, store_gregs, fetch_xtregs, store_xtregs): Likewise. --- gdb/m32r-linux-nat.c | 14 +++----------- 1 file changed, 3 insertions(+), 11 deletions(-) (limited to 'gdb/m32r-linux-nat.c') diff --git a/gdb/m32r-linux-nat.c b/gdb/m32r-linux-nat.c index 9d9bef3..a33de23 100644 --- a/gdb/m32r-linux-nat.c +++ b/gdb/m32r-linux-nat.c @@ -26,6 +26,7 @@ #include "nat/gdb_ptrace.h" #include #include +#include "inf-ptrace.h" /* Prototypes for supply_gregset etc. */ #include "gregset.h" @@ -194,12 +195,7 @@ static void m32r_linux_fetch_inferior_registers (struct target_ops *ops, struct regcache *regcache, int regno) { - int tid; - - /* GNU/Linux LWP ID's are process ID's. */ - tid = ptid_get_lwp (inferior_ptid); - if (tid == 0) - tid = ptid_get_pid (inferior_ptid); /* Not a threaded program. */ + pid_t tid = get_ptrace_pid (regcache_get_ptid (regcache)); /* Use the PTRACE_GETREGS request whenever possible, since it transfers more registers in one system call, and we'll cache the @@ -221,11 +217,7 @@ static void m32r_linux_store_inferior_registers (struct target_ops *ops, struct regcache *regcache, int regno) { - int tid; - - /* GNU/Linux LWP ID's are process ID's. */ - if ((tid = ptid_get_lwp (inferior_ptid)) == 0) - tid = ptid_get_pid (inferior_ptid); /* Not a threaded program. */ + pid_t tid = get_ptrace_pid (regcache_get_ptid (regcache)); /* Use the PTRACE_SETREGS request whenever possible, since it transfers more registers in one system call. */ -- cgit v1.1
