Re: CFI technologies in GCC

Bumping this thread. Would anyone be interested in CFI technology contributions to GCC? From: Victor Tong Sent: Tuesday, August 3, 2021 5:49 PM To: gcc@gcc.gnu.org Subject: CFI technologies in GCC   Hello, I'm interested in learning about any forward edge control-flow integrity

CFI technologies in GCC

otect indirect calls? I'm particularly curious about more general solutions since VTV is limited to virtual calls, IBT is limited to x86 and Intel hardware, and RAP requires a GRSecurity license. Thanks, Victor

Lack of latest binutils in gcc 11 docker image

HI team I am trying to use the gcc 11 docker hub image to build AMX code but it fails /usr/local/lib/gcc/x86_64-linux-gnu/11.1.0/include/amxtileintrin.h: Assembler messages: /usr/local/lib/gcc/x86_64-linux-gnu/11.1.0/include/amxtileintrin.h:42: Error: no such instruction: `ldtilecfg (%rdi)' /usr/

Re: GCC 10.1 Release Candidate available from gcc.gnu.org

Vararg templates. GCC vs Clang

arm,gcc and dsp instructions

Code generated uses these assembly dsp instructions sometimes (I think critical parts should be assembly written), but it exists any kind of patch or derivative to "tell" gcc to improve the code generated using these kind of 1 cycle instructions more offently? Thanks in advance.

Is it possible to catch overflow in long long multiply ?

Hi, I'm using gcc "long long" type for my calculator. I have to check integer overflow. I'm using sign compare to check overflow, but it doesn't work for 10^16 * 10^4 : 1 * 1 Here you have my code to check overflow : long long produit = a * b; // a,b: long long bool ok;
