/* GMP_WRAPPERS: the gmp library uses heap allocation in places for
76
temporary storage. This greatly complicates relocatable bignum
77
allocation in GCL, which is a big winner in terms of performance.
78
The old procedure was to patch gmp to use alloca in such instances.
79
Aside from possible silently introducing bugs as gmp evolves, such
80
a policy also runs the risk of colliding with gmp's stated policy
81
of storing pointers in allocated blocks, a possiblity GCL's
82
conservative garbage collector is not designed to handle. Here we
83
implement a policy of preventing garbage collection inside of gmp
84
calls in any case. In case of non-inplace calls, where source and
85
destination arguments are distinct, we simply longjmp back to the
86
front of the call if a gbc would be needed and try the call again,
87
as any previous partial write into the destination is of no
88
consequence. Just as is the case with the alloc_contblock and
89
alloc_relblock algorithms themselves, on the second pass (as
90
indicated by jmp_gmp) new pages are added if there is still not
91
enough room in lieu of GBC. In case of in-place calls, we schedule
92
a GBC call after the gmp call completes, relying on the allocator
93
to add pages immediately to the type to satisfy the allocation when
94
necessary. jmp_gmp counts the pass for non-in-place calls, and is
95
set to -1 otherwise. 20040815 CM*/
