Posted in reply to Leandro Lucarella | http://d.puremagic.com/issues/show_bug.cgi?id=3391 --- Comment #1 from Leandro Lucarella <llucax@gmail.com> 2009-10-17 18:00:47 PDT --- Maybe this is useful. For this file: $ cat -n dbg.d 1 2 void dummy_function() 3 { 4 char[][] str_array; 5 str_array ~= "hello"; 6 str_array ~= "world"; 7 int[2] int_sarray; 8 int_sarray[0] = 1; 9 int_sarray[1] = -1; 10 } 11 DMD (svn 1.x branch at r215) generates this: <1><6c>: Abbrev Number: 5 (DW_TAG_array_type) <6d> DW_AT_sibling : <0x7f> <71> DW_AT_type : <0x65> While LDC generates: <2><86>: Abbrev Number: 3 (DW_TAG_variable) <87> DW_AT_name : str_array <91> DW_AT_decl_file : 1 <92> DW_AT_decl_line : 4 <93> DW_AT_type : <0x121> <97> DW_AT_location : 2 byte block: 75 70 (DW_OP_breg5: -16) I will attach the full dump of objdump -W for both DMD and LDC. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |
