[RFC][clang/llvm] Allow efficient implementation of libc's memory functions in C/C++
...ic attribute to disable the synthesis of a single call __attribute__((disable_call_synthesis("memcpy"))) Question: Is it possible to specify the attribute several times on a function to disable many calls? 1.2 A specific attribute to disable synthesis of all libc calls __attribute__((disable_libc_call_synthesis)) With this one we are losing precision and we may inline too much. There is also the question of what is considered a libc function, LLVM mainly defines target library calls. 1.3 Stretch - a specific attribute to redirect a single synthesizable function.
