From 89e673a481dc6d7003dc332afabaf4a3e4d96a66 Mon Sep 17 00:00:00 2001 From: Stu Grossman Date: Thu, 4 Jul 1996 00:49:25 +0000 Subject: * sparcl-tdep.c (_initialize_sparc_tdep) config/sparc/tm-sparc.h, config/sparc/tm-sparclite.h: Initialize tm_print_insn from TM_PRINT_INSN, which comes from the tm file. * Makefile.in (INTERNAL_LDFLAGS): Add in flags from configure. * configure configure.in: Only make sol-thread.o for native. Also, switch to dlopened libthread_db.so.1. * sol-thread.c: Switch to using dlopen to get the thread_db library. * configure, configure.in: Change test for libthread_db to only work for configs where build/host/target are the same. --- gdb/ChangeLog | 19 ++++++ gdb/config/sparc/tm-sparc.h | 6 +- gdb/config/sparc/tm-sparclite.h | 6 ++ gdb/configure | 138 ++++++++++++++++------------------------ gdb/configure.in | 8 ++- gdb/sparc-tdep.c | 2 +- 6 files changed, 90 insertions(+), 89 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 605bae3..79447dc 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,9 @@ +Wed Jul 3 15:56:08 1996 Stu Grossman (grossman@critters.cygnus.com) + + * sparcl-tdep.c (_initialize_sparc_tdep) config/sparc/tm-sparc.h, + config/sparc/tm-sparclite.h: Initialize tm_print_insn from + TM_PRINT_INSN, which comes from the tm file. + Tue Jul 02 21:41:20 1996 Mark Alexander * coffread.c, dbxread.c, elfread.c, mipsread.c, nlmread.c, @@ -10,6 +16,19 @@ Tue Jul 02 21:41:20 1996 Mark Alexander * symtab.h: Define SIZEOF_SECTION_OFFSETS macro to simplify allocation of section_offsets. +Tue Jun 11 12:02:55 1996 Stu Grossman (grossman@critters.cygnus.com) + + * Makefile.in (INTERNAL_LDFLAGS): Add in flags from configure. + * configure configure.in: Only make sol-thread.o for native. + Also, switch to dlopened libthread_db.so.1. + * sol-thread.c: Switch to using dlopen to get the thread_db + library. + +Thu Jun 13 16:53:25 1996 Stu Grossman (grossman@critters.cygnus.com) + + * configure, configure.in: Change test for libthread_db to only + work for configs where build/host/target are the same. + Tue Jul 2 15:04:20 1996 Michael Meissner * config/powerpc/{linux.mh,xm-linux.h}: New files, for Linux on diff --git a/gdb/config/sparc/tm-sparc.h b/gdb/config/sparc/tm-sparc.h index b85602f..cec159d 100644 --- a/gdb/config/sparc/tm-sparc.h +++ b/gdb/config/sparc/tm-sparc.h @@ -110,7 +110,7 @@ extern CORE_ADDR sparc_pc_adjust PARAMS ((CORE_ADDR)); #define STACK_ALIGN(ADDR) (((ADDR)+7)&-8) -/* Sequence of bytes for breakpoint instruction. */ +/* Sequence of bytes for breakpoint instruction (ta 1). */ #define BREAKPOINT {0x91, 0xd0, 0x20, 0x01} @@ -641,3 +641,7 @@ extern int deferred_stores; passed as doubles and then converted in the callee. */ #define COERCE_FLOAT_TO_DOUBLE 1 + +/* Select the sparc disassembler */ + +#define TM_PRINT_INSN print_insn_sparc diff --git a/gdb/config/sparc/tm-sparclite.h b/gdb/config/sparc/tm-sparclite.h index eb84b0c..85fd584 100644 --- a/gdb/config/sparc/tm-sparclite.h +++ b/gdb/config/sparc/tm-sparclite.h @@ -21,6 +21,12 @@ Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA. */ #include "sparc/tm-sparc.h" +/* Select the sparclite disassembler.
