From: Peter Schauer Date: Sat, 19 Feb 1994 11:24:36 +0000 (+0000) Subject: * mdebugread.c (new_psymtab): Pass in section_offsets and set X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=847d9775304e0c338098147e303c7e3d9e5d6827;p=binutils-gdb.git * mdebugread.c (new_psymtab): Pass in section_offsets and set them in the pst. * mdebugread.c (handle_psymbol_enumerators): New function to enter the enumerators of an ecoff enum into the partial symbol table. * mdebugread.c (parse_partial_symbols): Call it. * symfile.c (reread_symbols): Initialize objfile->*_psymbols.next. * symmisc.c (dump_psymtab): Fix typo, clean up output of section offsets. Cast psymtab->read_symtab to PTR before passing it to gdb_print_address. * i386-tdep.c (i386_skip_prologue): Skip over instructions that set up the global offset table pointer in pic compiled code. * config/mips/tm-mips.h (FIX_CALL_DUMMY): For big endian targets, error() on TYPE_CODE_FLT arguments whose size is greater than 8, swap all other TYPE_CODE_FLT arguments as mips_push_arguments ensures that floats are promoted to doubles before they are pushed on the stack. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 61ca75aeb56..c787b28deaa 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,22 @@ +Sat Feb 19 03:17:32 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de) + + * mdebugread.c (new_psymtab): Pass in section_offsets and set + them in the pst. + * mdebugread.c (handle_psymbol_enumerators): New function to enter + the enumerators of an ecoff enum into the partial symbol table. + * mdebugread.c (parse_partial_symbols): Call it. + * symfile.c (reread_symbols): Initialize objfile->*_psymbols.next. + * symmisc.c (dump_psymtab): Fix typo, clean up output of section + offsets.
