From 09424cff8c26073312e0bdc342989a955c766e31 Mon Sep 17 00:00:00 2001 From: Andreas Arnez Date: Tue, 13 May 2014 11:05:57 +0000 Subject: [PATCH] Remove 'arch' field from regset structure. Removes the 'arch' field from the regset structure, since it represents the only "dynamic" data in a regset. It was referenced in some regset supply- and collect routines, to get access to the gdbarch associated with the regset. Naturally, the affected routines always have access to the regcache to be supplied to or collected from. Thus the gdbarch associated with that regcache can be used instead. --- gdb/ChangeLog | 18 ++++++++++++++++++ gdb/amd64-tdep.c | 6 ++++-- gdb/amd64obsd-tdep.c | 3 ++- gdb/i386-tdep.c | 12 ++++++++---- gdb/i386obsd-tdep.c | 3 ++- gdb/nios2-linux-tdep.c | 1 - gdb/ppc-linux-tdep.c | 15 +++++---------- gdb/ppcfbsd-tdep.c | 6 ++---- gdb/regset.c | 1 - gdb/regset.h | 3 --- 10 files changed, 41 insertions(+), 27 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 38cd57c5783..d329143898d 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,21 @@ +2014-05-21 Andreas Arnez + + * regset.h (struct regset): Remove gdbarch field. + * regset.c (regset_alloc): Drop initialization of gdbarch field. + * nios2-linux-tdep.c (nios2_core_regset): Likewise. + * ppcfbsd-tdep.c (ppc32_fbsd_gregset, ppc64_fbsd_gregset): + Likewise. + * ppc-linux-tdep.c (ppc32_linux_gregset, ppc64_linux_gregset) + (ppc32_linux_fpregset, ppc32_linux_vrregset) + (ppc32_linux_vsxregset): Likewise. + * i386obsd-tdep.c (i386obsd_aout_supply_regset): Get the gdbarch + via the regcache instead of the regset. + * i386-tdep.c (i386_supply_gregset, i386_collect_gregset) + (i386_supply_fpregset, i386_collect_fpregset): Likewise. + * amd64obsd-tdep.c (amd64obsd_supply_regset): Likewise. + * amd64-tdep.c (amd64_supply_fpregset, amd64_collect_fpregset): + Likewise. + 2014-05-21 Andreas Arnez * alpha-linux-tdep.c (alpha_linux_gregset, alpha_linux_fpregset): diff --git a/gdb/amd64-tdep.c b/gdb/amd64-tdep.c index 035b460afa1..1b9797a29a5 100644 --- a/gdb/amd64-tdep.c +++ b/gdb/amd64-tdep.c @@ -2842,7 +2842,8 @@ static void amd64_supply_fpregset (const struct regset *regset, struct regcache *regcache, int regnum, const void *fpregs, size_t len) { - const struct gdbarch_tdep *tdep = gdbarch_tdep (regset->arch);
