The standard calls environments like this -"freestanding implementations." - -This does *not* imply that the upb core can be compiled directly on a -freestanding implementation. Even the core uses library functions -that are not directly available on freestanding implementations -(notably malloc()/free(), vsnprintf(), and assert()). So compiling on -freestanding implementations may require implementing compatibility -versions of functions like malloc(). - -Also, Linux is not technically a freestanding implementation either, -since it does not accept functions that return float or double on -x86-64 (these use SSE registers which are disabled in kernel mode). |
