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.
