- Why is -march=native not enabled by default by compilers IDEs?
Why no march=native by default? As you have pointed out, besides producing binaries incompatibility with older CPUs, march=native isn't necessarily beneficial It improves performance in some cases such as numerical computing But it is not beneficial in many other cases, and is sometimes detrimental
- What is the default for gcc -march option? - Stack Overflow
There is no `-march=generic' option because `-march' indicates the instruction set the compiler can use, and there is no generic instruction set applicable to all processors In contrast, `-mtune' indicates the processor (or, in this case, collection of processors) for which the code is optimized
- what is march parameter when compile a c file - Stack Overflow
I saw these two kinds of make parameters: make -march=corei7-avx xxxx xxxx make -march-icelake-server xxxx xxx arch is understood, what's the m meaning? Where can I find which arch can be used
- What are my available march mtune options? - Stack Overflow
Is there a way to get gcc to output the available -march=arch options? I'm getting build errors (tried -march=x86_64) and I don't know what my options are The compiler I'm using is a proprietary
- What flags does -march=native activate with Clang?
With GCC one is able to print out the specific flags that -march=native triggers Is it possible to have Clang print similar information?
- sql - How do I use select with date condition? - Stack Overflow
In sqlserver, how do I compare dates? For example: Select * from Users where RegistrationDate >= '1 20 2009' (RegistrationDate is datetime type) Thanks
- Implementation of March memory testing algorithm
I am looking for a memory testing algorithm that will help my team verify the design and test during production (bad soldering, cross-connected address data lines, mismatched impedances, mirroring
- How to correctly determine -march and -mtune for Intel processors?
On x86 processors, just use -march=native GCC will handle the rest by setting arch and tune to same value ARM is trickier since GCC sometimes segfault's when using -march=native You should also use a modern GCC or maybe Clang Clang creates better code than GCC with some SIMD source code You will need to benchmark to determine which performs best for your code
