From 63f58cc52974c191fe73f2e32ca1178b1b9f31ed Mon Sep 17 00:00:00 2001 From: Peter Schauer Date: Thu, 9 Nov 2000 09:49:00 +0000 Subject: Add auto-solib-add support for AIX, remove obsolete and unused SOLIB_SYMBOLS_MANUAL code, cleanup of AIX shared library handling code. * rs6000-nat.c (vmap_symtab): Do not try to modify offsets if symbols are not yet loaded. (vmap_add_symbols): New function to add symbols for a vmap entry. (add_vmap): Turn errors into warnings, return NULL vmap upon failure. Add symbols via vmap_add_symbols only if requested. (xcoff_relocate_core): Allow debugging of core files without an executable file. Handle NULL returns from add_vmap gracefully. * xcoffsolib.c (solib_add): Remove, no longer needed. (solib_info): Do not check for new shared libraries if there is no inferior process. (sharedlibrary_command): Made static. Do not check for new shared libraries if there is no inferior process. Add symbols for requested shared libraries via vmap_add_symbols. (_initialize_solib): Add `set auto-solib-add' command. * xcoffsolib.h (vmap_add_symbols): Add prototype declaration. * config/rs6000/tm-rs6000.h (PC_LOAD_SEGMENT): Move from here ... * config/rs6000/nm-rs6000.h: ... to here, this is an AIX native feature. * config/powerpc/tm-macos.h, config/powerpc/tm-ppc-eabi.h, config/powerpc/tm-ppc-nw.h, config/rs6000/tm-rs6000ly.h: Remove #undef PC_LOAD_SEGMENT. * config/powerpc/aix.mt, config/rs6000/aix4.mt, config/rs6000/rs6000.mt (TDEPFILES): Move xcoffsolib.o from here ... * config/powerpc/aix.mh, config/rs6000/aix4.mh, config/rs6000/rs6000.mh (NATDEPFILES): ... to here, xcoffsolib.o contains AIX native code only. * rs6000-tdep.c: Remove #include xcoffsolib.h, no longer needed. * xcoffsolib.h (xcoff_relocate_symtab_hook): Remove declaration. * rs6000-nat.c (_initialize_core_rs6000): Remove setting of xcoff_relocate_symtab_hook, no longer needed. * xcoffsolib.c (solib_info, sharedlibrary_command): Remove xcoff_relocate_symtab_hook indirection, call xcoff_relocate_symtab directly, as xcoffsolib.c is now compiled in native AIX configurations only. * Makefile.in: Update dependencies for rs6000-tdep.o, rs6000-nat.o and xcoffsolib.o. --- gdb/config/powerpc/aix.mh | 3 ++- gdb/config/powerpc/aix.mt | 2 +- gdb/config/powerpc/tm-macos.h | 3 --- gdb/config/powerpc/tm-ppc-eabi.h | 1 - gdb/config/powerpc/tm-ppc-nw.h | 1 - 5 files changed, 3 insertions(+), 7 deletions(-) (limited to 'gdb/config/powerpc') diff --git a/gdb/config/powerpc/aix.mh b/gdb/config/powerpc/aix.mh index ba3e0c2..30e4080 100644 --- a/gdb/config/powerpc/aix.mh +++ b/gdb/config/powerpc/aix.mh @@ -4,7 +4,8 @@ XM_FILE= xm-aix.h XDEPFILES= NAT_FILE= nm-aix.h -NATDEPFILES= fork-child.o infptrace.o inftarg.o corelow.o rs6000-nat.o xcoffread.o +NATDEPFILES= fork-child.o infptrace.o inftarg.o corelow.o rs6000-nat.o \ + xcoffread.o xcoffsolib.o # When compiled with cc, for debugging, this argument should be passed. # We have no idea who our current compiler is though, so we skip it. diff --git a/gdb/config/powerpc/aix.mt b/gdb/config/powerpc/aix.mt index 38436ee..985f71b 100644 --- a/gdb/config/powerpc/aix.mt +++ b/gdb/config/powerpc/aix.mt @@ -1,3 +1,3 @@ # Target: PowerPC running AIX -TDEPFILES= rs6000-tdep.o xcoffsolib.o ppc-linux-tdep.o +TDEPFILES= rs6000-tdep.o ppc-linux-tdep.o TM_FILE= tm-ppc-aix.h diff --git a/gdb/config/powerpc/tm-macos.h b/gdb/config/powerpc/tm-macos.h index bfd7a73..1cb5050 100644 --- a/gdb/config/powerpc/tm-macos.h +++ b/gdb/config/powerpc/tm-macos.h @@ -22,6 +22,3 @@ #include "rs6000/tm-rs6000.h" #define GDB_TARGET_POWERPC - -/* This is no use to us. */ -#undef PC_LOAD_SEGMENT diff --git a/gdb/config/powerpc/tm-ppc-eabi.h b/gdb/config/powerpc/tm-ppc-eabi.h index 57e056b..aef54dc 100644 --- a/gdb/config/powerpc/tm-ppc-eabi.h +++ b/gdb/config/powerpc/tm-ppc-eabi.h @@ -30,7 +30,6 @@ #undef DEFAULT_LR_SAVE #define DEFAULT_LR_SAVE 4 /* eabi saves LR at 4 off of SP */ -#undef PC_LOAD_SEGMENT #undef PROCESS_LINENUMBER_HOOK #undef TEXT_SEGMENT_BASE diff --git a/gdb/config/powerpc/tm-ppc-nw.h b/gdb/config/powerpc/tm-ppc-nw.h index 7306ea0..32a58f4 100644 --- a/gdb/config/powerpc/tm-ppc-nw.h +++ b/gdb/config/powerpc/tm-ppc-nw.h @@ -26,7 +26,6 @@ #define GDB_TARGET_POWERPC -#undef PC_LOAD_SEGMENT #undef PROCESS_LINENUMBER_HOOK #endif /* TM_PPC_NW_H */ -- cgit v1.1
