gcc books, gcc debug (errata)

[gérard Calliet]

(our build version is 4.7.3)

Hello,

I'm just a beginner in gcc. (I contributed to the rebuild of the gnat 
ada compiler (version 3.4.7) on OpenVMS last year: 
https://github.com/AdaLabs/gnat-vms).

As I do love books and encyclopedic learning attitude, I searched for a 
good book about gcc.

I found this reference: Source Code Anaysis of GCC, Lixiang Yang. But it 
seems it is out of print. Is there someone who could sell me one?

By the way my interests on gcc now are about the debug machinery (in my 
version 3.4.7, or something like that). Every information or synthesis 
about that very wellcomed.

Thanks,

Gérard Calliet, pia-sofer Paris
