From 7ed49443c244d7a9e911f013fcdd70306a349866 Mon Sep 17 00:00:00 2001 From: Jim Blandy Date: Tue, 22 May 2001 21:02:41 +0000 Subject: Add support for the GNU V3 C++ ABI. (Includes changes by Dan Berlin.) * gnu-v3-abi.c: New file. * minsyms.c: #include "value.h" and "cp-abi.h". (install_minimal_symbols): Check the minimal symbol table for symbols that look mangled in the V3 style, and select the V3 ABI if we find any. * Makefile.in (SFILES): Add gnu-v3-abi.c. (COMMON_OBS): Add gnu-v3-abi.o. (gnu-v3-abi.o): Add new rule. (minsyms.o): Depend on $(cp_abi_h) and $(value_h). --- gdb/minsyms.c | 19 ++++++++++++++++++- 1 file changed, 18 insertions(+), 1 deletion(-) (limited to 'gdb/minsyms.c') diff --git a/gdb/minsyms.c b/gdb/minsyms.c index 7608297..0ed38d2 100644 --- a/gdb/minsyms.c +++ b/gdb/minsyms.c @@ -47,6 +47,8 @@ #include "symfile.h" #include "objfiles.h" #include "demangle.h" +#include "value.h" +#include "cp-abi.h" /* Accumulate the minimal symbols for each objfile in bunches of BUNCH_SIZE.
