8 years agoProvide right LDD offset bound in avr_address_cost
Senthil Kumar Selvaraj [Fri, 23 Sep 2016 07:12:35 +0000 (07:12 +0000)]
Provide right LDD offset bound in avr_address_cost

This patch fixes cost computation in avr_address_cost - instead of the
hardcoded 61, it uses the already existing MAX_LD_OFFSET(mode) macro.

This showed up when investigating a code size regression in the ivopts
pass. That pass computes address_cost with and without an offset to
decide on the right induction variable candidate(s). The legitimate
address target hook returns false for offsets more than 63, so the
pass calls the TARGET_ADDRESS_COST hook with 62 as the offset.

The avr_address_cost hook returns 18 as the cost, and the ivopts pass
concludes that the cost of address with *any* offset is 18, which is not
true - the higher cost is incurred only with offsets bigger than MAX_LD_OFFSET.
This in turn results in a suboptimal choice of induction variables in the
ivopts pass. The patch changes the hardcoded 61 to use the mode
specific MAX_LD_OFFSET instead.

Regression testing with just that fix showed one additional
compilation timeout. That turned out to be the same as
https://lists.nongnu.org/archive/html/avr-gcc-list/2014-03/msg00010.html
- the middle end takes too much time to decide on the best strategy to
multiply DImode values on a 64 bit host. This already causes timeouts
for a few builtin-arith-overflow-* tests (see
https://gcc.gnu.org/ml/gcc-testresults/2016-09/msg02018.html), so it
isn't really related to this fix. Just providing a cost estimate for
DImode mul fixes the timeout though, so the patch does that by scaling
SImode costs by 2 for DImode muls.

With both changes in, there are no regressions, and the
builtin-arith-overflow-* tests now PASS and don't timeout.

Ian Lance Taylor [Thu, 22 Sep 2016 20:32:16 +0000 (20:32 +0000)]
compiler: compile runtime.getcaller{pc,sp} into builtin functions

    The runtime functions runtime.getcallerpc and runtime.getcallersp are
    intended to be efficient ways to get the return and frame address of the
    caller (that is, the caller of runtime.getcallerpc).  In the C code that
    is implemented by simply using C macros:

    This patch essentially implements those macros in the Go code.

    It would be nice if we could just use //extern for this, but it doesn't
    work because the runtime code passes the right argument.  Of course we
    could change the runtime code, but these are common enough that I'd
    prefer to avoid the difference from the gc version of the runtime code.

    This patch corrects the existing declaration of __builtin_return_address
    to use uint32, rather than uint, for the parameter type.  The builtin
    functions take the C type "unsigned int", which for the targets we use
    corresponds to the Go type uint32.  Not that it should matter, really.

8 years agocompiler, runtime: replace hashmap code with Go 1.7 hashmap
Ian Lance Taylor [Wed, 21 Sep 2016 20:58:51 +0000 (20:58 +0000)]
compiler, runtime: replace hashmap code with Go 1.7 hashmap

    This change removes the gccgo-specific hashmap code and replaces it with
    the hashmap code from the Go 1.7 runtime.  The Go 1.7 hashmap code is
    more efficient, does a better job on details like when to update a key,
    and provides some support against denial-of-service attacks.

    The compiler is changed to call the new hashmap functions instead of the
    old ones.

    The compiler now tracks which types are reflexive and which require
    updating when used as a map key, and records the information in map type
    descriptors.

    Map_index_expression is simplified.  The special case for a map index on
    the right hand side of a tuple expression has been unnecessary for some
    time, and is removed.  The support for specially marking a map index as
    an lvalue is removed, in favor of lowering an assignment to a map index
    into a function call.  The long-obsolete support for a map index of a
    pointer to a map is removed.

    The __go_new_map_big function (known to the compiler as
    Runtime::MAKEMAPBIG) is no longer needed, as the new runtime.makemap
    function takes an int64 hint argument.

    The old map descriptor type and supporting expression is removed.

    The compiler was still supporting the long-obsolete syntax `m[k] = 0,
    false` to delete a value from a map.  That is now removed, requiring a
    change to one of the gccgo-specific tests.

    The builtin len function applied to a map or channel p is now compiled
    as `p == nil ? 0 : *(*int)(p)`.  The __go_chan_len function (known to
    the compiler as Runtime::CHAN_LEN) is removed.

    Support for a shared zero value for maps to large value types is
    introduced, along the lines of the gc compiler.  The zero value is
    handled as a common variable.

    The hash function is changed to take a seed argument, changing the
    runtime hash functions and the compiler-generated hash functions.
    Unlike the gc compiler, both the hash and equal functions continue to
    take the type length.

    Types that can not be compared now store nil for the hash and equal
    functions, rather than pointing to functions that throw.  Interface hash
    and comparison functions now check explicitly for nil.  This matches the
    gc compiler and permits a simple implementation for ismapkey.

    The compiler is changed to permit marking struct and array types as
    incomparable, meaning that they have no hash or equal function.  We use
    this for thunk types, removing the existing special code to avoid
    generating hash/equal functions for them.

    The C runtime code adds memclr, memequal, and memmove functions.

    The hashmap code uses go:linkname comments to make the functions
    visible, as otherwise the compiler would discard them.

    The hashmap code comments out the unused reference to the address of the
    first parameter in the race code, as otherwise the compiler thinks that
    the parameter escapes and copies it onto the heap.  This is probably not
    needed when we enable escape analysis.

    Several runtime map tests that ere previously skipped for gccgo are now
    run.

    The Go runtime picks up type kind information and stubs.  The type kind
    information causes the generated runtime header file to define some
    constants, including `empty`, and the C code is adjusted accordingly.

    A Go-callable version of runtime.throw, that takes a Go string, is
    added to be called from the hashmap code.
