2017-01-13PR 78534 Change character length from int to size_tJanne Blomqvist31-157/+440
In order to handle large character lengths on (L)LP64 targets, switch the GFortran character length from an int to a size_t. This is an ABI change, as procedures with character arguments take hidden arguments with the character length. I also changed the _size member in vtables from int to size_t, as there were some cases where character lengths and sizes were apparently mixed up and caused regressions otherwise. Although I haven't tested, this might enable very large derived types as well. Also, as there are some places in the frontend were negative character lengths are used as special flag values, in the frontend the character length is handled as a signed variable of the same size as a size_t, although in the runtime library it really is size_t. I haven't changed the character length variables for the co-array intrinsics, as this is something that may need to be synchronized with OpenCoarrays. This is v4 of the patch. v3 was applied but had to reverted due to breaking bootstrap. The fix is in resolve.c:resolve_charlen, where it's necessary to check that an expression is constant before using mpz_sgn. Overview of v3 of the patch: All the issues pointed out by FX's review of v2 have been fixed. In particular, there are now new functions gfc_mpz_get_hwi and gfc_mpz_set_hwi, similar to the GMP functions mpz_get_si and mpz_set_si, except that they get/set a HOST_WIDE_INT instead of a long value. Similarly, gfc_get_int_expr now takes a HOST_WIDE_INT instead of a long, gfc_extract_long is replaced by gfc_extract_hwi. Also, the preliminary work to handle gfc_charlen_type_node being unsigned has been removed.

2017-01-13Avoid excessively-big hash tables in empty-add cyclesRichard Sandiford2-5/+30
A big source of cache misses when compiling a recent version of gimple-match.ii was the call to cv_cache.empty () in clear_cv_cache. The problem was that at one early point the hash table had grown to 8191 entries (128k on LP64 hosts). It then stayed at that size for the rest of the compilation, even though subsequent uses needed only a small number of entries (usually fewer than ten). We would still clear the whole 128k each time clear_cv_cache was called. empty() already looks for cases where the hash table is very big and cuts it down. At the moment it fires when the table is 1M in size and reduces it to the next selected prime above 1K (so almost 2K in practice). One fix would have been to lower the threshold, but that didn't feel like the right approach. Reducing the current limit of 1M by a factor of 8 would be pretty significant on its own, but I think this cv_cache behaviour would have been a problem even with 64k or 32k tables. I think the existing check is really for cases in which even a well-populated table would need to be shrunk rather than cleared. Here the problem isn't that the table is excessively big in absolute terms, more that one outlier has made the table much too big for the general case. traverse() already shrinks the table if it's "too empty", which is taken to be if: no. elements * 8 < capacity && capacity > 32 So an alternative would be to apply the same test (and the same choice of shrunken size) to empty_slow too. The patch below does this. It gives a 2.5% improvement in gimple-match.ii compile time at -O0 -g and doesn't seem to adversely affect any other tests I've tried. Of course, there's a theoretical risk of a table alternating between one large element count and one small element count. If there was a factor of eight difference between the two, we could shrink the table on seeing each small element count, then grow it again when adding the large number of elements. That seems pretty unlikely in practice though. Also, empty_slow() does involve a traversal if some form of manual gc is needed on active elements, so trying to recover from an outlier should have even more benefit there. (cv_cache uses automatic gc and so the traversal gets optimised away.) The calculation of the existing 1M threshold was assuming that each entry was pointer-sized. This patch makes it use the actual size of the entry instead. Tested on aarch64-linux-gnu and x86_64-linux-gnu. gcc/ * hash-table.h (hash_table::too_empty_p): New function. (hash_table::expand): Use it. (hash_table::traverse): Likewise. (hash_table::empty_slot): Use sizeof (value_type) instead of sizeof (PTR) to convert bytes to elements.

2017-01-13Short-circuit alt_fail case in record_reg_classesRichard Sandiford2-1/+21
record_reg_classes is often the hottest function when generating unoptimised output. It seems typical for over 60% of the instructions it handles to be moves, and of course moves tend to be the instructions with the longest constraint strings. Maybe we should avoid using move constraints to set costs in unoptimised output and instead use the "natural" class for the mode being moved. That's too invasive for stage 3 though. However, seeing so many moves means that we see many "failing" alternatives, usually because of '*' or because of hard registers in function call sequences. The frequency of alternatives that are detected as failures after the first operand tends again to be more than 60%. Previously we would continue to process the other operands of the alternative regardless. This patch instead adds a short-cut. As well as avoiding unnecessary work, it means that the alt_fail variable can be jump-threaded away. Tested on aach64-linux-gnu and x86_64-linux-gnu. It reduces compile time by about 1% on some tests with "-g -O0". gcc/ * ira-costs.c (record_reg_classes): Break from the inner loop early once alt_fail is known to be true. Update outer loop handling accordingly. From-SVN: r244446
