Targetting p0847 for GCC14 (explicit object parameter)

I would like to boldly suggest implementing P0847 should be targeted at GCC14. In my anecdotal experiences, this feature is very important to people, and very important to myself, I believe it should be a priority. I am not suggesting this without offering to contribute, however because of my inex

On inform diagnostics in plugins, support scripts for gdb and modeling creation of PyObjects for static analysis

Hi everyone, I am one of the GSoC participants this year — in particular, I am working on a static analyzer plugin for CPython extension module code. I'm encountering a few challenges and would appreciate any guidance on the following issues: 1) Issue with "inform" diagnostics in the plugin: I am

Hi, I've been mapping where the analyzer is lacking support of the operator new different variants. I've written a bunch of test cases already to demonstrate it, you can find them below. They are not yet formatted for a patch submission, and as some of them may require new warnings, I didn't use d

When do I need -fnon-call-exceptions?

I wrote some simple program that set a signal handler for SIGFPE, throws a C++ exception in the signal handler and catches the exception. I compiled with and without -fnon-call-exceptions (on x64 Linux). In both cases, the result was the same: the exception was caught and the destructors were cal

About addition of .symtab and .strtab sections in simple-object-elf.c

Hi Everyone, I am working on the GSOC project "Bypass Assembler when generating LTO object files." My mentors and I have decided to work on the ELF files first, so I will add .symtab along with the symbol __gnu_lto_slim to the ELF file as a first step.

[OpenACC] cheking the status of AMD GPU offloading performance

Hi everyone, I have a general question regarding the GPU offloading support on AMD GPUs using OpenACC or OpenMP. I am doing some tests by compiling the new version of GCC (13 and 14), following the instructions online (https://gcc.gnu.org/wiki/Offloading#How_to_try_offloading_enabled_GCC). I
