Bug#151886: [Gcl-devel] Re: gcl/maxima on hppa

[Camm Maguire <camm@enhanced.com>]

Greetings!  An update:

1) Optimization, even at -O, still fails with gcc-3.2.  I get a
   maxima, but it crashes on one of the tests. -ffunction-sections
   still in.

2) I cannot seem to get gcl's stratified garbage collection option to
   work on hppa.  This basically mprotects the core pages as
   read-only, then traps segfault signals on write attempts,
   unprotects the page and marks it for garbage collection.  The
   sigaction calls don't appear to redirect control to the handler on
   SIGSEGV, however.  This works as is on most other Debian
   platforms. 

3) I have this setup on paer, so can provide gdb dumps to anyone who
   wants to try to fix this.

4) I suppose the -ffunction-sections is still required without the -g,
   but haven't tested this.

5) Just uploaded a maxima which should build for the first time on
   hppa. 

Take care,
