This directory contains code that is ANSI C but uses parts of the
|
||
|
|
standard library that are not available to very limited environments
|
||
|
|
like Linux Kernel modules. 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).
