HINTS FOR PORTING TO NEW PLATFORMS
In case you're not able to use Pth on a new and esoteric platform,
here are a few hints.
Pth has only one part which perhaps has to be ported to new platforms: the
machine context initialization, i.e. the function pth_mctx_set() in
pth_mctx.c. The exercise is to write a pth_mctx_set() function which
initializes a `jmp_buf' (see setjmp(3)) with a given function and stack, so
when the next longjmp(3) is done on this `jmp_buf', the function starts
executing on the given stack.
By default, Pth uses a very tricky sigstack/sigaltstack() based approach for
establishing this `jmp_buf' which is mostly portable to all major Unix
platforms which support the involved POSIX functions (see rse-pmt.ps for a
detailed description of the trick). So the chance is very high that this
approach also works for forthcoming platforms and no real porting is
required.
When this approach should not work (for instance brain-dead achient
GNU/Linux versions have a dummy sigstack/sigaltstack(), so we've no chance
this way), then you've to provide an alternative implementation. This
usually is done be fiddling around with the ingredients of a `jmp_buf'
structure. For this look inside your /usr/include/setjmp.h (plus files it
includes) and there especially for things like _pc or JB_PC (the program
counter) and _sp or JB_SP (the stack pointer). Then write an alternative
pth_mctx_set() function in pth_mctx.c.
Currently, as mentioned, Pth requires such an alternative only under
GNU/Linux where sigstack/sigaltstack() are dummy functions. Look at the
GNU/Linux pth_mctx_set() variant in pth_mctx.c to get an impression what
type of `jmp_buf' fiddling you perhaps have to do for esoteric platforms.
Don't be confused by the fact that such specialized pth_mctx_set() functions
are just a few lines long while the standard function is very large. That's
all just needed for maximum portability. The goal nevertheless only is to
initialize a `jmp_buf' with PC and SP. That's all...
Additionally see the INSTALL document for the --enable-mctx-XXX options.
These can be used to easily try out mctx combinations on a platform, too.
