(gdb) r Starting program: /home/sana/test/gdbC/opt_none_debug_64/all_types.exe Breakpoint 1, fp_params (fp1=47.9700012, dbl1=123456789.98765433, ldbl1=Can't deal with a floating point number of 16 bytes. ) at all_types.c:41 41 fresult = fp1 + dbl1 + ldbl1 + lfp1; (gdb) whatis ldbl1 type = long double (gdb) p ldbl1 $1 = Can't deal with a floating point number of 16 bytes. (gdb) Debug information for ldbl1 is: s <1><16d7>: Abbrev Number: 6 (DW_TAG_base_type) DW_AT_byte_size : 16 DW_AT_bit_size : 80 DW_AT_bit_offset : 0 DW_AT_encoding : 4 (float) DW_AT_name : long double <2><18f8>: Abbrev Number: 5 (DW_TAG_variable) DW_AT_decl_line : 70 DW_AT_decl_column : 16 DW_AT_decl_file : 1 DW_AT_accessibility: 1 (public) DW_AT_name : ldbl1 DW_AT_type : <16d7> DW_AT_location : 3 byte block: 92 c 10 (DW_OP_bregx: 12 16) DW_AT_external : 0 One thing is that gcc can't compile this test.. still I think this needs to be supported in gdb. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
