Avoid the possibility of code discrepancies like one fixed with the
previous change and improve the structure of code by selecting between
push and non-push operations in a single place in `vax_output_int_move'.
The PUSHAB/MOVAB address moves are never actually produced from this
code as the SImode invocation of this function is guarded with the
`nonsymbolic_operand' predicate, but let's not mess up with this code
too much on this occasion and keep the piece in place.
* config/vax/vax.c (vax_output_int_move): Unify push operation
selection.
Check the output operand for representing pushing a value onto the stack
rather than the constant 0 input in determining whether to use the PUSHL
or the CLRL instruction for a SImode move. The latter actually works by
means of using the predecrement addressing mode with the SP register and
the machine code produced even takes the same number of bytes, however
at least with some VAX implementations it incurs a performance penalty.
Besides, we don't want to check the wrong operand anyway and have code
that works by chance only.
Add a test case covering push operations; for operands different from
constant zero there is actually a code size advantage for using PUSHL
rather than the equivalent MOVL instruction.

operand for constant 0 push operation.

Remove an assertion the failure of which has not been actually observed,
but which appears clearly dangerous, for when the QMATH DImode add/sub

output operand. Adjust the relevant inline comment accordingly.

FAIL: gcc.c-torture/compile/sync-1.c -O0 (internal compiler error)
causing numerous failures in regression testing.
While requesting an addition operation to be produced for the constant
operands of 0 and -1 may seem silly, technically there is nothing wrong
with it, and non-QMATH code (as with the `-mno-qmath' option) has no
issues with that, so neither should QMATH code. This operation will
normally be folded in later passes anyway.
Observe then, that adding or subtracting constant 0 amounts to a move
(and we even have a machine instruction available to do that with a
single operation) so handle the case explicitly, swapping the addends if
so required, removing the assertion failure and along with that 70 test
suite failures like:

Unfortunately, my latest tree-ssa-math-opts.c patch broke the following
testcase. The problem is that the code is adding .ADD_OVERFLOW or
.SUB_OVERFLOW before or after the stmt on which the function has been
called, which is normally a addition or subtraction that has all the
operands.
But in the a > ~b optimization that stmt is the ~b stmt and the other
comparison operand might be defined only after that ~b stmt, so we can't
insert the .ADD_OVERFLOW next to ~b that we want to delete, but need to
insert it before the a > temp comparison that uses it; and in that case
when removing the BIT_NOT_EXPR stmt we need to ensure the caller doesn't do
gsi_next because gsi_remove already points the iterator to the next stmt.

This is a small refactoring which exposes some helper functions in the
vectorizer so they can be used in other places.
gcc/ChangeLog:
* tree-vect-patterns.c (vect_mark_pattern_stmts): Remove static inline.
* tree-vect-slp.c (vect_create_new_slp_node): Remove static and only
set smts if valid.
* tree-vectorizer.c (vec_info::add_pattern_stmt): New.
(vec_info::set_vinfo_for_stmt): Optionally enforce read-only.
* tree-vectorizer.h (struct _slp_tree): Use new types.
(lane_permutation_t, lane_permutation_t): New.
(vect_create_new_slp_node, vect_mark_pattern_stmts): New.
This patch addresses some of the issues that I found when looking into the
failures of the scan-assembler-symbol-section tests on Solaris/SPARC.
* The first issue was that on Solaris/SPARC, section names are
double-quoted, both with as and gas:
.section ".text"
When using as, the section flag and type syntax is completely
different from other ELF targets:
.section "my_named_section",#alloc,#execinstr,#progbits
This patch fixes this by stripping double quotes from section names.
* However, this didn't work initially (only the leading quote was
stripped), which is due to David's recent AIX patch: with the
introduction of the new capturing group to handle both .section (ELF)
and .csect (XCOFF), $full_section_directive would never be empty on
ELF and Mach-O targets, so the extraction of the section name didn't
work any longer. This had also broken the Darwin tests completely.
* With working double quote stripping, all but one of the tests PASSed
on Solaris/SPARC, the exception being:
FAIL: gcc.dg/20021029-1.c scan-assembler-symbol-section symbol ar (found __sparc_get_pc_thunk.l7) has section ^\\\\.(const|rodata)|\\\\[RO\\\\] (found .text.__sparc_get_pc_thunk.l7%__sparc_get_pc_thunk.l7)
This is due to the symbol name (ar) not being anchored in the test and
unexpectedly matchting __sparc_get_pc_thunk.l7.
* Next, I ran the tests on Darwin 11 and found two failing tests:
FAIL: gcc.dg/darwin-sections.c scan-assembler-symbol-section symbol ^_a\$ (symbol not found) has section \\\\.data
FAIL: gcc.dg/darwin-sections.c scan-assembler-symbol-section symbol ^_b\$ (symbol not found) has section \\\\.data
is due to Iain's recent "Darwin : Begin rework of zero-fill sections."
patch which emits
.globl _a
.zerofill __DATA,__common,_a,1,0
This is already scanned for, so the two scans above can just go.
The other failing test is
FAIL: g++.dg/gomp/tls-5.C -std=c++14 scan-assembler-symbol-section symbol ^_?_ZGR2ir_\$ (symbol not found) has section ^\\\\.tdata|\\\\[TL\\\\]
FAIL: g++.dg/gomp/tls-5.C -std=c++14 scan-assembler-symbol-section symbol ^_?ir\$ (symbol not found) has section ^\\\\.tbss|\\\\[TL\\\\]
Other scans are guarded by target tls_native, and indeed the assembler
output has
___emutls_v._ZGR2ir_:
___emutls_t._ZGR2ir_:
___emutls_v.ir:
Unfortunately scan-assembler-symbol-section doesn't support selects
yet, which this test implements both for the benefit of this test and
for symmetry.
With those changes, test results are clean now on sparc-sun-solaris2.11,
i386-pc-solaris2.11, i386-apple-darwin11.4.2, and
powerpc-ibm-aix7.2.4.0.

At the moment, class hierarchies that use is_a are expected
to define specialisations like:
template <>
template <>
inline bool
is_a_helper <cgraph_node *>::test (symtab_node *p)
{
return p->type == SYMTAB_FUNCTION;
}
But this doesn't scale well to larger hierarchies, because it only
defines ::test for an argument that is exactly “symtab_node *”
(and not for example “const symtab_node *” or something that
comes between cgraph_node and symtab_node in the hierarchy).
For example:
struct A { int x; };
struct B : A {};
struct C : B {};
template <>
template <>
inline bool
is_a_helper <C *>::test (A *a)
{
return a->x == 1;
}
bool f(B *b) { return is_a<C *> (b); }
gives:
warning: inline function ‘static bool is_a_helper<T>::test(U*) [with U = B; T = C*]’ used but never defined
and:
bool f(const A *a) { return is_a<const C *> (a); }
gives:
warning: inline function ‘static bool is_a_helper<T>::test(U*) [with U = const A; T = const C*]’ used but never defined
This patch instead allows is_a to be implemented by specialising
is_a_helper as a whole, for example:
template<>
struct is_a_helper<C *> : static_is_a_helper<C *>
{
static inline bool test (const A *a) { return a->x == 1; }
};
It also adds a general specialisation of is_a_helper for const
pointers. Together, this makes both of the above examples work.

(static_is_a_helper): Likewise.
(is_a_helper): Inherit from reinterpret_is_a_helper.
(is_a_helper<const T *>): New specialization.
A later patch will add more iterator-related utilities. Rather than
putting them all directly in coretypes.h, it seemed better to add a
new header file, here called "iterator-utils.h". This preliminary
patch moves the existing iterator_range class there too.
I used the same copyright date range as coretypes.h “just to be sure”.
gcc/
* coretypes.h (iterator_range): Move to...
* iterator-utils.h: ...this new file.
noop_move_p currently keeps any instruction that has a REG_EQUAL
note, on the basis that the equality might be useful in future.
But this creates a perverse incentive not to add potentially-useful
REG_EQUAL notes, in case they prevent an instruction from later being
removed as dead.
The condition originates from flow.c:life_analysis_1 and predates
the changes tracked by the current repository (1992). It probably
made sense when most optimisations were done on RTL rather than FE
trees, but it seems counterproductive now.
gcc/
* rtlanal.c (noop_move_p): Don't check for REG_EQUAL notes.
I noticed during compatibility testing that clang warns that this
operator won't be implicitly const in C++14 onwards.
gcc/
* vec.h (vnull::operator vec<T, A, L>): Make const.
