- Subject: [wwwdocs] Mention -faddress-sanitizer in gcc-4.8/changes.html
Dear all,
attached is a first draft for -faddress-sanitizer in the release notes.
I am aware that some changes are imminent,* but I want make a start.
Comments?
Tobias
* For instance:
- PowerPC/PowerPC64 Linux support
- Renaming to -fsanitizer=address
- Addition of -fsanitizer=thread
- libsanitizer builds with sparc (but ASAN_SHADOW_SHIFT is missing?)
- Darwin nearly works?
