Coco 1.1.6 — 2009-09-08

Fix compilation of the GCC inline assembler code on x64. Now works when compiled as C++ code (reported by Jonathan Sauer) or with -fPIC (reported by Jim Pryor).
Added GCC inline assembler for faster context switching on Sparc. Thanks to Takayuki Usui.

Upgraded to patch cleanly into Lua 5.1.4.
Added GCC inline assembler for faster context switching on x64. Thanks to Robert G. Jakabosky.

Upgraded to patch cleanly into Lua 5.1.3.
Fixed setjmp method for ARM with recent glibc versions. Thanks to the LuaTeX developers.
Fixed setjmp method for x86 on Mac OS X (rarely used, default is GCC inline assembler). Thanks to Jason Toffaletti.

Upgraded to patch cleanly into Lua 5.1.2.
Merged patch from Zachary P. Landau for a Linux/ARM setjmp method (uClibc and glibc).

Upgraded to patch cleanly into Lua 5.1.1.
C stacks are deallocated early: when a coroutine ends, and not when the coroutine object is collected. This mainly benefits Windows Fibers.
Windows threads get the required Fiber context when resuming a coroutine and not just on creation.

Upgraded to patch cleanly into Lua 5.1 (final).
Added GCC inline assembler for context switching on x86 and MIPS32 [up to 3x faster].
New targets for setjmp method: Mac OS X/x86, Solaris/x86 and x64 and Linux/MIPS32.
Workaround for WinXP problem with GetCurrentFiber().
The minimum C stack size has been increased to 32K+4K.
Removed lcocolib.c and integrated the (much smaller) changes into lbaselib.c.
Note for embedders: this means you no longer need to call luaopen_coco().
Optional Valgrind support requires version 3.x. Renamed define to USE_VALGRIND.
C stacks are now registered with Valgrind.

This is the first pre-release of Coco. It targets Lua 5.1-work6 only and is no longer available for download.
