Is there a way to make GCC output the source code comments or corresponding c++ source code that generated a set of assembler instructions in the .s files? The only thing that seems to come close is the -fverbose-asm switch, but this does not give enough commentry for me to quickly and easily track down the corresponding source line in the c++ source code. -- Artur Szostak Tel. +27 21 650 3356 Mobile: +27 82 297 9502 Emails: artur@xxxxxxxxxxxxxxxxxxx artursz@xxxxxxxxxxx AIM: artiblot Skype: artiblot Room: 4T6 Address: R.W.
