Rationale

Other APIs
x86 and floating-point env

No inline-assembler

Some newer compiler (for instance MSVC 10 for x86_64 and itanium) do not support inline assembler. [1]. Inlined assembler generates code bloating which his not welcome on embedded systems.

fcontext_t

Boost.Context provides the low level API fcontext_t which is implemented in assembler to provide context swapping operations. fcontext_t is the part to port to new platforms.

[Note] Note

Context switches do not preserve the signal mask on UNIX systems.

fcontext_t is an opaque pointer.
