No FP compile option for Lua? [was: upcoming changes in Lua 5.2]

[ramsdell@... (John D. Ramsdell)]

For Lua 5.2, please consider adding compile time support for hardware
without floating point instructions.  The patch to enable this support
is in the "Go Long Lua!" section in

http://lua-users.org/wiki/LuaPowerPatches

I tested the patch under 5.1.3, and all is well.

An example of hardware without floating point instructions comes from
Xen.  It provides a very lightweight virtual machine via Mini-OS.
This 32-bit operating system does not save and restore floating point
registers during a context switch, so you cannot use floating point
operations.
