The code isn't very pretty either. + + During development it can help to disable the redzones, since seeing the + rest of the destination written can show where the wrong part is, or if + the dst pointers are off by 1 or whatever. The magic DEADVAL initial + fill (see below) will show locations never written. + + The -s option can be used to test only certain size operands, which is + useful if some new code doesn't yet support say sizes less than the + unrolling, or whatever. + + When a problem occurs it'll of course be necessary to run the program + under gdb to find out quite where, how and why it's going wrong. Disable + the spinner with the -W option when doing this, or single stepping won't + work. Using the "-1" option to run with simple data can be useful. + + New functions to test can be added in try_array[]. If a new TYPE is + required then add it to the existing constants, set up its parameters in + param_init(), and add it to the call() function. Extra parameter fields + can be added if necessary, or further interpretations given to existing + fields. + + + Portability: + + This program is not designed for use on Cray vector systems under Unicos, + it will fail to compile due to missing _SC_PAGE_SIZE. Those systems + don't really have pages or mprotect. We could arrange to run the tests + without the redzones, but we haven't bothered currently. + + + Enhancements: + + umul_ppmm support is not very good, lots of source data is generated + whereas only two limbs are needed. + + Make a little scheme for interpreting the "SIZE" selections uniformly. + + Make tr->size==SIZE_2 work, for the benefit of find_a which wants just 2 + source limbs. Possibly increase the default repetitions in that case. + + Automatically detect gdb and disable the spinner (use -W for now). + + Make a way to re-run a failing case in the debugger. Have an option to + snapshot each test case before it's run so the data is available if a + segv occurs. (This should be more reliable than the current print_all() + in the signal handler.) + + When alignment means a dst isn't hard against the redzone, check the + space in between remains unchanged. + + When a source overlaps a destination, don't run both s[i].high 0 and 1, + as s[i].high has no effect. Maybe encode s[i].high into overlap->s[i]. + + When partial overlaps aren't done, don't loop over source alignments + during overlaps. + + Try to make the looping code a bit less horrible. Right now it's pretty + hard to see what iterations are actually done. + + Perhaps specific setups and loops for each style of function under test + would be clearer than a parameterized general loop. There's lots of + stuff common to all functions, but the exceptions get messy. + + When there's no overlap, run with both src>dst and src<dst. A subtle + calling-conventions violation occurred in a P6 copy which depended on the + relative location of src and dst. + + multiplier_N is more or less a third source region for the addmul_N + routines, and could be done with the redzoned region scheme. + +*/ + + +/* always do assertion checking */ +#define WANT_ASSERT 1 + +#include "config.h" + +#include <errno.h> +#include <limits.h> +#include <signal.h> +#include <stdio.h> +#include <stdlib.h> +#include <string.h> +#include <time.h> + +#if HAVE_UNISTD_H +#include <unistd.h> +#endif + +#if HAVE_SYS_MMAN_H +#include <sys/mman.h> +#endif + +#include "gmp-impl.h" +#include "longlong.h" +#include "tests.h" + + +#if !HAVE_DECL_OPTARG +extern char *optarg; +extern int optind, opterr; +#endif + +#if !
