# Supported targets
In the following lists, supported targets are only those that have been tested
and confirmed working. It is quite possible that libco will work on more
processors, compilers and operating systems than those listed below.

The "Overhead" is the cost of switching co-routines, as compared to an ordinary
C function call.

## libco.x86
* **Overhead:** ~5x
* **Supported processor(s):** 32-bit x86
*** Supported compiler(s**): any
* **Supported operating system(s):**
  * Windows
  * Mac OS X
  * Linux
  * BSD

##   libco.amd64
* **Overhead:** ~10x (Windows), ~6x (all other platforms)
* **Supported processor(s):** 64-bit amd64
*** Supported compiler(s**): any
* **Supported operating system(s):**
  * Windows
  * Mac OS X
  * Linux
  * BSD

## libco.ppc
* **Overhead:** ~20x
* **Supported processor(s):** 32-bit PowerPC, 64-bit PowerPC
* **Supported compiler(s):** GNU GCC
* **Supported operating system(s):**
  * Mac OS X
  * Linux
  * BSD
  * Playstation 3

**Note:** this module contains compiler flags to enable/disable FPU and Altivec
support.

## libco.fiber
This uses Windows' "fibers" API.
* **Overhead:** ~15x
* **Supported processor(s):** Processor independent
* **Supported compiler(s):** any
* **Supported operating system(s):**
  * Windows

## libco.sjlj
This uses the C standard library's `setjump`/`longjmp` APIs.
* **Overhead:** ~30x
* **Supported processor(s):** Processor independent
* **Supported compiler(s):** any
* **Supported operating system(s):**
  * Mac OS X
  * Linux
  * BSD
  * Solaris

## libco.ucontext
This uses the POSIX "ucontext" API.
* **Overhead:** ***~300x***
* **Supported processor(s):** Processor independent
* **Supported compiler(s):** any
* **Supported operating system(s):**
  * Linux
  * BSD
