Field Documentation

void(* host_hooks::extra_signals)(void)

size_t(* host_hooks::gt_pch_alloc_granularity)(void)

Return the alignment required for allocating virtual memory. Usually this is the same as pagesize.

void*(* host_hooks::gt_pch_get_address)(size_t size, int fd)

Identify an address that's likely to be free in a subsequent invocation of the compiler. The area should be able to hold SIZE bytes. FD is an open file descriptor if the host would like to probe with mmap.

int(* host_hooks::gt_pch_use_address)(void *addr, size_t size, int fd, size_t offset)

ADDR is an address returned by gt_pch_get_address. Attempt to allocate SIZE bytes at the same address and load it with the data from FD at OFFSET. Return -1 if we couldn't allocate memory at ADDR, return 0 if the memory is allocated but the data not loaded, return 1 if done.
