From 2fda49774f178145b87bc2081c69c58c39747d1c Mon Sep 17 00:00:00 2001 From: Daniel Jacobowitz Date: Tue, 30 Jul 2002 19:03:49 +0000 Subject: [PATCH] * ppc-linux-tdep.c (ELF_NGREG, ELF_NFPREG, ELF_NVRREG) (ELF_FPREGSET_SIZE, ELF_GREGSET_SIZE): New enums. (fetch_core_registers, ppc_linux_supply_gregset) (ppc_linux_supply_fpregset): New functions. (ppc_linux_regset_core_fns): New. (_initialize_ppc_linux_tdep): Call add_core_fns. * ppc-tdep.h: Add prototypes for ppc_linux_supply_fpregset and ppc_linux_supply_gregset. * ppc-linux-nat.c (supply_gregset): Call ppc_linux_supply_gregset. (supply_fpregset): Call ppc_linux_supply_fpregset. * config/powerpc/linux.mh (NATDEPFILES): Remove core-regset.o and corelow.o. * config/powerpc/linux.mt (TDEPFILES): Add corelow.o. --- gdb/ChangeLog | 16 +++++++ gdb/config/powerpc/linux.mh | 4 +- gdb/config/powerpc/linux.mt | 2 +- gdb/ppc-linux-nat.c | 23 +--------- gdb/ppc-linux-tdep.c | 83 +++++++++++++++++++++++++++++++++++++ gdb/ppc-tdep.h | 2 + 6 files changed, 106 insertions(+), 24 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 48dc32fc690..a3d2047a6a4 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,19 @@ +2002-07-30 Daniel Jacobowitz + + * ppc-linux-tdep.c (ELF_NGREG, ELF_NFPREG, ELF_NVRREG) + (ELF_FPREGSET_SIZE, ELF_GREGSET_SIZE): New enums. + (fetch_core_registers, ppc_linux_supply_gregset) + (ppc_linux_supply_fpregset): New functions. + (ppc_linux_regset_core_fns): New. + (_initialize_ppc_linux_tdep): Call add_core_fns. + * ppc-tdep.h: Add prototypes for ppc_linux_supply_fpregset + and ppc_linux_supply_gregset. + * ppc-linux-nat.c (supply_gregset): Call ppc_linux_supply_gregset. + (supply_fpregset): Call ppc_linux_supply_fpregset. + * config/powerpc/linux.mh (NATDEPFILES): Remove core-regset.o and + corelow.o. + * config/powerpc/linux.mt (TDEPFILES): Add corelow.o. + 2002-07-30 Daniel Jacobowitz * symtab.c (lookup_symbol): Demangle before lowercasing. diff --git a/gdb/config/powerpc/linux.mh b/gdb/config/powerpc/linux.mh index 0e3c2a68feb..d0a2104bd89 100644 --- a/gdb/config/powerpc/linux.mh +++ b/gdb/config/powerpc/linux.mh @@ -4,8 +4,8 @@ XM_FILE= xm-linux.h XM_CLIBS= NAT_FILE= nm-linux.h -NATDEPFILES= infptrace.o inftarg.o fork-child.o corelow.o linux-proc.o \ - core-regset.o ppc-linux-nat.o proc-service.o thread-db.o lin-lwp.o \ +NATDEPFILES= infptrace.o inftarg.o fork-child.o linux-proc.o \ + ppc-linux-nat.o proc-service.o thread-db.o lin-lwp.o \ gcore.o LOADLIBES = -ldl -rdynamic diff --git a/gdb/config/powerpc/linux.mt b/gdb/config/powerpc/linux.mt index a1d08c2d38e..1fb6fd8b8af 100644 --- a/gdb/config/powerpc/linux.mt +++ b/gdb/config/powerpc/linux.mt @@ -1,6 +1,6 @@ # Target: Motorola PPC on Linux TDEPFILES= rs6000-tdep.o ppc-linux-tdep.o ppc-sysv-tdep.o solib.o \ - solib-svr4.o solib-legacy.o + solib-svr4.o solib-legacy.o corelow.o TM_FILE= tm-linux.h SIM_OBS = remote-sim.o diff --git a/gdb/ppc-linux-nat.c b/gdb/ppc-linux-nat.c index 25616c0f047..721e05f8c24 100644 --- a/gdb/ppc-linux-nat.c +++ b/gdb/ppc-linux-nat.c @@ -475,21 +475,7 @@ store_inferior_registers (int regno) void supply_gregset (gdb_gregset_t *gregsetp) { - int regi;
