I wanted to take a closer look at the assember generated by gcc for
ia64, so I added the following CFLAGS: -fverbose-asm -save-temps
It's very strange, but despite -fverbose-asm - the comments are NOT
kept along the assembler code which makes the work VERY hard.
The machine I am testing it with is woody with gcc 2.96.
Is that the problem? Or am I missing something?
Thank you for your help
