(add_pe_exported_sym): Use SECTION_DATA->INDEX for call to prim_record_mininal_symbol_and_info. (add_pe_forwarded_sym): Use known section number of forwarded symbol in call to prim_record_minimal_symbol_and_info. (read_pe_exported_syms): Set index field of section_data. --- gdb/coff-pe-read.c | 28 ++++++++++++++++++++++------ 1 file changed, 22 insertions(+), 6 deletions(-) (limited to 'gdb/coff-pe-read.c') diff --git a/gdb/coff-pe-read.c b/gdb/coff-pe-read.c index 749c109..0fcd15f 100644 --- a/gdb/coff-pe-read.c +++ b/gdb/coff-pe-read.c @@ -53,6 +53,7 @@ struct read_pe_section_data unsigned long rva_end; /* End offset within the pe. */ enum minimal_symbol_type ms_type; /* Type to assign symbols in section. */ + unsigned int index; /* BFD section number. */ char *section_name; /* Recorded section name. */ }; @@ -93,7 +94,7 @@ read_pe_section_index (const char *section_name) } } -/* Get the index of the named section in our own full arrayi. +/* Get the index of the named section in our own full array. text, data and bss in that order.
