Richard Earnshaw [Thu, 18 Jul 2019 13:56:52 +0000 (13:56 +0000)]
[arm] Fix incorrect modes with 'borrow' operations

Looking through the arm backend I noticed that the modes used to pass
comparison types into subtract-with-carry operations were being
incorrectly set.  The result is that the compiler is not truly
self-consistent.  To clean this up I've introduced a new predicate,
arm_borrow_operation (borrowed from the AArch64 backend) which can
match the comparison type with the required mode and then fixed all
the patterns to use this.  The split patterns that were generating
incorrect modes have all obviously been fixed as well.

The basic rule for the use of a borrow is:
- if the condition code was set by a 'subtract-like' operation (subs, cmp),
  then use CCmode and LTU.
- if the condition code was by unsigned overflow of addition (adds), then
  use CC_Cmode and GEU.

* config/arm/predicates.md (arm_borrow_operation): New predicate.
* config/arm/arm.c (subdi3_compare1): Use CCmode for the split.

compiler: fix bug in handling of unordered set during exporting

    In CL 183850 a change was made to combine tracking/discovery of
    exported types and imported packages during export data generation. As
    a result of this refactoring a bug was introduced: the new code can
    potentially insert items into the exports set (an unordered_set) while
    iterating through the same set, which is illegal according to the spec
    for std::unordered_set.

    This patch fixes the problem by changing the type discovery phase to
    iterate through a separate list of sorted exports, as opposed to
    iterating through the main unordered set.  Also included is a change
    to fix the code that looks for variables that are referenced from
    inlined routine bodies (this code wasn't scanning all of the function
    that it needed to scan).

runtime: expose the g variable

    Currently, getg is implemented in C, which loads the thread-local
    g variable. The g variable is declared static in C.

    This CL exposes the g variable, so it can be accessed from the Go
    side. This allows the Go compiler to inline getg calls to direct
    access of g.

    Currently, the actual inlining is only implemented in the gollvm
    compiler. The g variable is thread-local and the compiler backend
    may choose to cache the TLS address in a register or on stack. If
    a thread switch happens the cache may become invalid. I don't
    know how to disable the TLS address cache in gccgo, therefore
    the inlining of getg is not implemented. In the future gccgo may
    gain this if we know how to do it safely.

[arch64] Fix ambiguous .md attribute uses

This patch is part of a series that fixes ambiguous attribute
uses in .md files, i.e. cases in which attributes didn't use
<ITER:ATTR> to specify an iterator, and in which <ATTR> could
have different values depending on the iterator chosen.

No behavioural change except for dropping the unused SVE
divide permutations.

Support multiple operand counts for .md @ patterns

This patch extends the support for "@..." pattern names so that
the patterns can have different numbers of operands.  This allows
things like binary and ternary operations to be handled in a
consistent way, a bit like optabs.  The generators assert that
the number of operands passed is correct for the underlying
instruction.

Also, replace_operands_with_dups iterated over the old rtx format
even after having decided to do a replacement, which broke with
match_operator.

compiler: ensure evaluation order in type hash/eq functions

    The type hash and equality functions are generated after the
    order_evaluations pass. They may contain shortcut operators and
    Set_and_use_temporary_expressions (e.g. from lowering a
    Binary_exprssion) that need to be ordered. Run order_evaluations
    and remove_shortcuts on these functions. (The hash functions
    may be fine, but to be on the safe side we run on them anyway.
    We do need to run on the equality functions.)

    A Set_and_use_temporary_expression is effectively an assignment,
    so it needs to be ordered. Otherwise if we insert a temporary
    statement before it, we may get wrong evaluation order.

    A test case is CL 185818.
