Swallow exception in gc_heap::fire_etw_allocation_event (#6571)

The gc_heap::fire_etw_allocation_event calls TypeHandle::GetName that can throw
due to OOM. But we don't want failures to fire event cause a failure during the GC,
so such exception should be swallowed and no event fired in such case.

when this function was transitively called from Thread::PerformPreemptiveGC which
was recently modified to have NOTHROW contract.
Interestingly, this was not detected by the static contract checker.

8 years agoReplace the LSRA stack with a hash table.
Pat Gavlin [Tue, 26 Jul 2016 13:27:06 +0000 (06:27 -0700)]
Replace the LSRA stack with a hash table.

LSRA currently uses a stack to find the `LocationInfo` for each register consumed
by a node. The changes in this stack's contents given a particular node are
governed by three factors:
- The number of registers the node consumes (`gtLsraInfo.srcCount`)
- The number of registers the node produces (`gtLstaInfo.dstCount`)
- Whether or not the node produces an unused value (`gtLsraInfo.isLocalDefUse`)

In all cases, `gtLsraInfo.srcCount` values are popped off of the stack in the
order in which they were pushed (i.e. in FIFO rather than LIFO order). If the
node produces a value that will be used, `gtLsraInfo.dstCount` values are
then pushed onto the stack. If the node produces an unused value, nothing is
pushed onto the stack.

Naively, it would appear that the number of registers a node consumes would be
at least the count of the node's non-leaf operands (to put it differently, one
might assume that any non-leaf operator that produces a value would define at
least one register). However, contained nodes complicate the situation: because
a contained node's execution is subsumed by its user, the contained node's
sources become sources for its user and the contained node does not define any
registers. As a result, both the number of registers consumed and the number of
registers produced by a contained node are 0. Thus, contained nodes do not
update the stack, and the node's parent (if it is not also contained) will
pop the values produced by the contained node's operands. Logically speaking,
it is as if a contained node defines the transitive closure of the registers
defined by its own non-contained operands.

The use of the stack relies on the property that even in linear order the
JIT's IR is still tree ordered. That is to say, given an operator and its
operands, any nodes that execute between any two operands do not produce
SDSU temps that are consumed after the second operand. IR with such a
shape would unbalance the stack.

The planned move to the LIR design given in #6366 removes the tree order
constraint in order to simplify understanding and manipulating the IR in the
backend. Because LIR may not be tree ordered, LSRA may no longer use a stack
to find the `LocationInfo` for a node's operands. This change replaces the
stack with a map from nodes to lists of `LocationInfo` values, each of
which describes a register that is logically defined (if not physically
defined) by that node. Only contained nodes logically define registers that
they do not physically define: contained nodes map to the list of
`LocationInfo` values logically defined by their operands. All non-contained
nodes map to the list of `LocationInfo` values that they physically define.
Non-contained nodes that do not define any registers are not inserted into
the map.

Linux/ARM: Fix +3000 bus errors of unit-test in case of O2/O3 levels (#6379)

**PROBLEM**
This patch is to resolve +3000 bus errors that are generated whenever we use
the aggressive optimization levels of clang (issue #5844 ).

When we enable the -O3 optimization level of the clang version(from clang 3.5
to clang 3.9(snapshot)), we have always got the lots of bus errors from the
coreCLR's unit tests. Actually, we can easily monitor SIGBUS signals (e.g.,
"misaligned memory access") with /proc/cpu/alignment facility in kernel space.
Using "echo 2 > /proc/cpu/alignment" makes Linux kernel fixes the problems
but the performance of the application will be degraded.
.source: http://lxr.free-electrons.com/source/Documentation/arm/mem_alignment

**VERSION 4**
. Use 'GET_UNALIGNED_VALXXX' macros in the CoreClr infra-structure without
  any need for ifdefs.

**VERSION 3**
.Apply this PR on only Linux/ARM for different system environment (Windows).

Here is .NET CI Report on Windows: Compile Error
error C2146: syntax error: missing ';' before identifier '__unaligned_int32'
(compiling source file D:\j\workspace\checked_windo---f6dc6fe4\src\jit\alloc.cpp)
[D:\j\workspace\checked_windo---f6dc6fe4\bin\obj\Windows_NT.x64.Checked\src\jit\
crossgen\clrjit_crossgen.vcxproj] Indication 1

**VERSION 2**
.Add UNALIGNED_ARM macro for handling ARM core specific optimization levels.
.Add RISC-based ARM core handling into the existing infra-structure of the
platform adaptation layer (PAL) for aggressive optimization cases on Linux/ARM.

**VERSION 1**
Basically, RISC-based ARM architecture requires aligned access with 4byte reads.
In order to support aggressive optimization levels such as O2/O3, let's use
attribute keyword of aligned(1) instead of using memcpy(2) in into
a properly aligned buffer or the packing attribute.

**BACKGROUND**
According to ARM information center(infocenter.arm.com), By default,
the ARM compiler expects normal C and C++ pointers to point
to an aligned word in memory. A type qualifier __packed is provided to
enable unaligned pointer access. If you want to define a pointer to a word
that can be at any address (that is, that can be at a non-natural alignment),
you must specify this using the __packed qualifier when defining the pointer:
__packed int *pi; // pointer to unaligned int

However, clang/llvm does not support the __packed qualifier such as
__attribute__((packed)) or __attribute__((packed, aligned(4)))

In -O0 (debug build) the innermost block is emitted as the following assembly,
which works properly:
 ldr r1, [r0, #24]
 ldr r2, [r0, #20]

In -O3 (release build) however the compiler realizes these fields are adjacent
and generates this assembly:
 ldrdeq  r2, r3, [r0, #20]
Unfortunately, vldr/ldrdb instructions always generate an alignment fault
(in practice). It seems that clang uses ldrb instruction although GCC uses
ldr instruction because armv7 supports unaligned ldr instruction.

Note: If some arm architectures (e.g., Linux/ARM Emulator) does not support
unaligned ldr, this issue is not generated with aggressive optimization
levels (e.g., -O2 and -O3).
