针对你遇到的错误“error: use of undeclared identifier 'memset'”,这通常意味着编译器无法识别memset函数。以下是一些可能的解决方案和检查点: 确认'memset'函数的使用环境: memset函数是C标准库中的一个函数,用于将内存块中的每个字节设置为特定的值。它通常在C和C++环境中使用。 检查是否包含了'memset'函数所...
memset() can be used at any time and for any kind of memory structure, including single variables, arrays, and objects. The limitation is that it can't properly set each element in an array to any value, because it doesn't have the concept of element. It initializesmemory, not arrays...
I am using STM32-P103 to decode NMEA sentences with some codes that they were already written and making small changes in them and I have notice that the use of functions like memset and memcpy makes the system go into an infinite loop where it can't come out. Is there a way to mak...

This is a correctness issue: When -fno-builtin is used, we must assume that we could be compiling the memcpy/memset implementations, so generating calls to them is problematic. Benchmark 1 (3 runs): ./release/bin/zig build -Doptimize=ReleaseFast -Dno-lib -Denable-llvm=false -Duse-llvm...
