[arm][1/3] Rename mul64 attr to widen_mul64

The mul64 attribute in types.md causes some confusion as it is used to represent
aarch32 instructions that do widening multiplication to generate 32->64 bit results.
But these types are shared with aarch64, which has native 64-bit multiplication operations.

Those are currently not properly represented, which I will fix in follow-up patches.
For now, this patch renames the mul64 attribute to widen_mul64 to more clearly communicate its meaning.

It mechanically updates all users of that name in config/arm/ (there are no users in config/aarch64).
There is thus no change in behaviour.

* config/arm/types.md (mul64): Rename to...

libphobos: Fix backtraces in Fibers on AArch64.

When throwing an Exception in the Fiber the backtrace generation
crashes.  This happens because backtrace does not func the stack bottom.
Using '.cfi_undefined x30' tells the debug info that the value in the lr
is unknown, which seems to be the nicest way to stop the unwinder.
Setting x30 to 0 is another option, however it still creates one invalid
frame in gdb, so the .cfi variant is used here instead.

Make recursion_check work for multiple threads

With multiple threads, using an unprotected static variable to check
whether recursion has occured isn't valid, as one thread might have
modified the variable, thus causing another thread to incorrectly

by using a thread-specific variable for the recursion check.

PR libstdc++/87308 adjust regex used in std::any pretty printer

The pretty printer for std::any fails when the contained value is a
locally-defined type, because the name in the debuginfo has
cv-qualifiers and ptr-declarators in different positions. The unexpected
format confuses the printer. This makes the printer's regex handle
either format.

scopes). This applies to all closure types defined in a given function,

5 years agoPR85434: Prevent spilling of stack protector guard's address on ARM
Thomas Preud'homme [Thu, 22 Nov 2018 14:46:17 +0000 (14:46 +0000)]
PR85434: Prevent spilling of stack protector guard's address on ARM

In case of high register pressure in PIC mode, address of the stack
protector's guard can be spilled on ARM targets as shown in PR85434,
thus allowing an attacker to control what the canary would be compared
against. ARM does lack stack_protect_set and stack_protect_test insn
patterns, defining them does not help as the address is expanded
regularly and the patterns only deal with the copy and test of the
guard with the canary.

This problem does not occur for x86 targets because the PIC access and
the test can be done in the same instruction. Aarch64 is exempt too
because PIC access insn pattern are mov of UNSPEC which prevents it from
the second access in the epilogue being CSEd in cse_local pass with the
first access in the prologue.

The approach followed here is to create new "combined" set and test
standard pattern names that take the unexpanded guard and do the set or
test. This allows the target to use an opaque pattern (eg. using UNSPEC)
to hide the individual instructions being generated to the compiler and
split the pattern into generic load, compare and branch instruction
after register allocator, therefore avoiding any spilling. This is here
implemented for the ARM targets. For targets not implementing these new
standard pattern names, the existing stack_protect_set and
stack_protect_test pattern names are used.

To be able to split PIC access after register allocation, the functions
had to be augmented to force a new PIC register load and to control
which register it loads into. This is because sharing the PIC register
between prologue and epilogue could lead to spilling due to CSE again
which an attacker could use to control what the canary gets compared
against.

Jonathan Wakely [Thu, 22 Nov 2018 13:42:39 +0000 (13:42 +0000)]
PR libstdc++/87520 Always pass type-punned type_info reference

The implementations of std::make_shared for -frtti and -fno-rtti are not
compatible, because they pass different arguments to
_Sp_counted_ptr_inplace::_M_get_deleter and so can't interoperate.
Either the argument doesn't match the expected value, and so the
shared_ptr::_M_ptr member is never set, or the type-punned reference is
treated as a real std::type_info object and gets dereferenced.

This patch removes the differences between -frtti and -fno-rtti, so that
typeid is never used, and the type-punned reference is used in both
cases. For backwards compatibility with existing code that passes
typeid(_Sp_make_shared_tag) that still needs to be handled, but only
after checking that the argument is not the type-punned reference (so
it's safe to treat as a real std::type_info object). The reference is
bound to an object of literal type, so that it doesn't need a guard
variable to make its initialization thread-safe.

This patch also fixes 87520 by ensuring that the type-punned reference
is bound to "a region of storage of suitable size and alignment to
contain an object of the reference's type" (as per the proposed
resolution of Core DR 453).

If all objects are built with the fixed version of GCC then -frtti and
-fno-rtti can be mixed freely and std::make_shared will work correctly.
If some objects are built with unfixed GCC versions then problems can
still arise, depending on which template instantiations are kept by the
linker.

Renlin Li [Wed, 21 Nov 2018 14:29:19 +0000 (14:29 +0000)]
[PATCH][PR84877]Dynamically align the address for local parameter copy on the stack when required alignment is larger than MAX_SUPPORTED_STACK_ALIGNMENT

As described in PR84877. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84877
The local copy of parameter on stack is not aligned.

For BLKmode paramters, a local copy on the stack will be saved.
There are three cases:
1) arguments passed partially on the stack, partially via registers.
2) arguments passed fully on the stack.
3) arguments passed via registers.

After the change here, in all three cases, the stack slot for the local
parameter copy is aligned by the data type.
The stack slot is the DECL_RTL of the parameter. All the references thereafter
in the function will refer to this RTL.

To populate the local copy on the stack,
For case 1) and 2), there are operations to move data from the caller's stack
(from incoming rtl) into callee's stack.
For case 3), the registers are directly saved into the stack slot.

In all cases, the destination address is properly aligned.
But for case 1) and case 2), the source address is not aligned by the type.
It is defined by the PCS how the arguments are prepared.
The block move operation is fulfilled by emit_block_move (). As far as I can see,
it will use the smaller alignment of source and destination.
This looks fine as long as we don't use instructions which requires a strict
larger alignment than the address actually has.

Here, it only changes receiving parameters.
The function assign_stack_local_1 will be called in various places.
Usually, the caller will constraint the ALIGN parameter.
For example via STACK_SLOT_ALIGNMENT macro.
assign_parm_setup_block will call assign_stack_local () with alignment from the
parameter type which in this case could be
larger than MAX_SUPPORTED_STACK_ALIGNMENT.

The alignment operation for parameter copy on the stack is similar to stack vars.
First, enough space is reserved on the stack. The size is fixed at compile time.
Instructions are emitted to dynamically get an aligned address at runtime
within this piece of memory.

This will unavoidably increase the usage of stack. However, it really depends on
how many over-aligned parameters are passed by value.
