From 21b4b2f28c3a4de55517693f3ce799cad8b42195 Mon Sep 17 00:00:00 2001 From: Jim Blandy Date: Wed, 6 Apr 2005 17:01:25 +0000 Subject: [PATCH] Move construction of IA-32 vector types to i386-tdep.c. * gdbtypes.c (build_builtin_type_vec64i, build_builtin_type_vec128i): Delete functions. (builtin_type_vec64i, builtin_type_vec128i): Delete variables. (build_gdbtypes): Don't initialize them. (_initialize_gdbtypes): Don't register GDBARCH swap entries for them. * gdbtypes.h (builtin_type_vec64i, builtin_type_vec128i): Delete declarations. (builtin_type_v2_float, builtin_type_v2_int32, builtin_type_v4_int16, builtin_type_v8_int8, builtin_type_v2_double, builtin_type_v4_float, builtin_type_v2_int64, builtin_type_v4_int32, builtin_type_v8_int16, builtin_type_v16_int8): Add extern declarations. * i386-tdep.c (i386_mmx_type, i386_sse_type): New variables. (i386_build_mmx_type, i386_build_sse_type): New functions. (i386_register_type): Call them, rather than referring to builtin_type_vec64i and builtin_type_vec128i. --- gdb/ChangeLog | 22 ++++++++++++++++ gdb/gdbtypes.c | 53 -------------------------------------- gdb/gdbtypes.h | 16 +++++++++--- gdb/i386-tdep.c | 68 +++++++++++++++++++++++++++++++++++++++++++++++-- 4 files changed, 100 insertions(+), 59 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 95b2f645cf1..30abadcff15 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,25 @@ +2005-04-05 Jim Blandy + + Move construction of IA-32 vector types to i386-tdep.c. + * gdbtypes.c (build_builtin_type_vec64i, + build_builtin_type_vec128i): Delete functions. + (builtin_type_vec64i, builtin_type_vec128i): Delete variables. + (build_gdbtypes): Don't initialize them. + (_initialize_gdbtypes): Don't register GDBARCH swap entries for + them. + * gdbtypes.h (builtin_type_vec64i, builtin_type_vec128i): Delete + declarations. + (builtin_type_v2_float, builtin_type_v2_int32, + builtin_type_v4_int16, builtin_type_v8_int8, + builtin_type_v2_double, builtin_type_v4_float, + builtin_type_v2_int64, builtin_type_v4_int32, + builtin_type_v8_int16, builtin_type_v16_int8): Add extern + declarations. + * i386-tdep.c (i386_mmx_type, i386_sse_type): New variables. + (i386_build_mmx_type, i386_build_sse_type): New functions. + (i386_register_type): Call them, rather than referring to + builtin_type_vec64i and builtin_type_vec128i. + 2005-04-02 Daniel Jacobowitz * mips-linux-tdep.c (mips_linux_o32_sigframe_init): Adjust diff --git a/gdb/gdbtypes.c b/gdb/gdbtypes.c index ce769b63349..86f1bebfead 100644 --- a/gdb/gdbtypes.c +++ b/gdb/gdbtypes.c @@ -94,9 +94,7 @@ struct type *builtin_type_v8hi; struct type *builtin_type_v4hi; struct type *builtin_type_v2si; struct type *builtin_type_vec64; -struct type *builtin_type_vec64i; struct type *builtin_type_vec128; -struct type *builtin_type_vec128i; struct type *builtin_type_ieee_single[BFD_ENDIAN_UNKNOWN]; struct type *builtin_type_ieee_single_big; struct type *builtin_type_ieee_single_little; @@ -917,34 +915,6 @@ build_builtin_type_vec64 (void) return t; } -static struct type * -build_builtin_type_vec64i (void) -{ - /* Construct a type for the 64 bit registers.
