Re: Checking for built-in functions from build systems

that what happens when built-ins are not inlined is not well defined. The libc may not implement the routine, or it's not clear which dependency should provide it. Thanks, Luca Bacci Il giorno mer 10 ago 2022 alle ore 23:27 Jonathan Wakely < jwakely@gmail.com> ha scritto: > > &

Checking for built-in functions from build systems

s, could a __is_builtin_inlined (func) macro be added to GCC? It should tell whether func is going to be substituted inline for the given compiler invocation 3. Is it true that conditionally-inlined built-ins are exactly those that come in the two variants of '__builtin_func' and 'func'? Thanks, Luca Bacci

Option to set the debug map (DW_AT_comp_dir) value "from scratch"

ap=/new/path/to/set to set the DW_AT_comp_dir path, directly, from scratch, without the need to look for the value to replace before. Thanks, Luca

What does 'experimental support for C++11' exactly mean for production work?

Hello, I would like to propose the adoption of C++11 to my colleagues for our production code. We use to rebuild everything with the same compiler version each time (GCC 4.7.3 for now), so ABI incompatibilities between different GCC versions are not an issue for us. However, with C++11 in mind

f you simply want to attend without speaking, you can register as well. We're trying to do a little outreach so the talks will be open to everybody, but of course we particularly welcome GNU contributors. Regards, -- Luca Saiu Home page: http://ageinghacker.net GNU epsilon: http://www.gnu.org/s

March=native with a main 64bit system and 32bit chroot

Hi all, I've a main Gentoo 64bit system with CHOST="x86_64-pc-linux-gnu" and CFLAGS="-march=native -mtune=native -O2 -pipe -fomit-frame-pointer". My cpu is a Pentium 4 Prescott and i'm using gcc-4.3.2. With this little script: "echo 'float x(float x){return x < 0 ? -x : x;}' > x.c && gcc -fverbose

[RFC] [PATCH] 32-bit pointers in x86-64

This proof of concept patch modifies GCC to have 32-bit pointers and longs on x86-64. This allows to create an "x86-32" architecture that takes advantage of the higher number of registers and support for 64-bit computation in x86-64 long mode while avoiding the disadvantage of increased memory usa
