14 months ago[ThinLTO] Fix internalization decisions for weak/linkonce ODR
Teresa Johnson [Thu, 1 Jun 2023 18:07:05 +0000 (11:07 -0700)]
[ThinLTO] Fix internalization decisions for weak/linkonce ODR

This fixes a runtime error that occurred due to incorrect
internalization of linkonce_odr functions where function pointer
equality was broken. This was hit because the prevailing copy was in a
native object, so the IR copies were not exported, and the existing code
internalized all of the IR copies. It could be fixed by guarding this
internalization on whether the defs are (local_)unnamed_addr, meaning
that their address is not significant (which we have in the summary
currently for linkonce_odr via the CanAutoHide flag). Or we can
propagate reference attributes as we do when determining whether a
global variable is read or write-only (reference edges are annotated
with whether they are read-only, write-only, or neither, and taking the
address of a function would result in a reference edge to the function
that is not read or write-only).

However, this exposed a larger issue with the internalization handling.
Looking at test cases, it appears the intent is to internalize when
there is a single definition of a linkonce/weak ODR symbol (that isn't
exported). This makes sense in the case of functions, because the
inliner can apply its last call to static heuristic when appropriate. In
the case where there is no prevailing copy in IR, internalizing all of
the IR copies of a linkonce_odr, even if legal, just increases binary
size. In that case it is better to fall back to the normal handling of
converting all non-prevailing copies to available_externally so that
they are eliminated after inlining.

In the case of variables, the existing code was attempting to
internalize the non-exported linkonce/weak ODR variables if they were
read or write-only. While this is legal (we propagate reference
attributes to determine this information), we don't even need to
internalize these here as there is later separate handling that
internalizes read and write-only variables when we process the module at
the start of the ThinLTO backend (processGlobalForThinLTO). Instead, we
can also internalize any non-exported variable when there is only one
(IR) definition, which is prevailing. And in that case, we don't need to
require that it is read or write-only, since we are guaranteed that all
uses must use that single definition.

In the new LTO API, if there are multiple defs of a linkonce or weak ODR
it will be marked exported, but it isn't clear that this will always be
true for the legacy LTO API. Therefore, require that there is only a
single (non-local) def, and that it is prevailing.

The test cases changes are both to reflect the change in the handling of
linkonce_odr IR copies where the prevailing def is not in IR (the main
correctness bug fix here), and to reflect the more aggressive
internalization of variables when there is only a single def, it is in
IR, and not exported.

I've also added some additional testing via the new LTO API.

[libc] Implement 'errno' on the GPU as a global integer internally

The C standard asserts that the `errno` value is an l-value thread local
integer. We cannot provide a generic thread local integer on the GPU
currently without some workarounds. Previously, we worked around this by
implementing the `errno` value as a special consumer class that made all
the writes disappear. However, this is problematic for internal tests.
Currently there are build failures because of this handling and it's
only likely to cause more problems the more we do this.

This patch instead makes the internal target used for testing export the
`errno` value as a simple global integer. This allows us to use and test
the `errno` interface correctly assuming we run with a single thread.
Because this is only used for the non-exported target we still do not
provide this feature in the version that users will use so we do not
need to worrk about it being incorrect in general.

that both be unlimited polymorphic if either is, and that both be
polymorphic if either is.  The justifications for the first restriction
is that the called procedure might change the type of an unlimited
polymorphic dummy argument, but as this cannot occur for a dummy
argument with INTENT(IN), we can relax the check to an optional

[compiler-rt] Avoid memintrinsic calls inserted by the compiler

D135716 introduced -ftrivial-auto-var-init=pattern where supported.
Unfortunately this introduces unwanted memset() for large stack arrays,
as shown by the new tests added for asan and msan (tsan already had this
test).

In general, the problem of compiler-inserted memintrinsic calls
(memset/memcpy/memmove) is not new to compiler-rt, and has been a
problem before.

To avoid introducing unwanted memintrinsic calls, we redefine
memintrinsics as __sanitizer_internal_mem* at the assembly level for
most source files automatically (where sanitizer_common_internal_defs.h
is included).

In few cases, redefining a symbol in this way causes issues for
interceptors, namely the memintrinsic interceptor themselves. For such
source files we have to selectively disable the redefinition.

Other alternatives have been considered, but simply do not work well in
the context of compiler-rt:

1. Linker --wrap:  this does not work because --wrap only
   applies to the final link, and would not apply when building
   sanitizer static libraries.

2. Changing references to memset() via objcopy:  this may work,
   but due to the complexities of the build system, introducing
   such a post-processing step for the right object files (in
   particular object files defining memset cannot be touched)
   seems infeasible.

The chosen solution works well (as shown by the tests). Other libraries
have chosen the same solution where nothing else works (see e.g. glibc's
"symbol-hacks.h").

v3:
- Don't use ALIAS() to alias internal_mem*() functions to
  __sanitizer_internal_mem*() functions, but just define them as
  ALWAYS_INLINE functions instead. This will work on darwin and windows.

v2:
- Fix ubsan_minimal build where compiler decides to insert
  memset/memcpy: ubsan_minimal has work without RTSanitizerCommonLibc,
  therefore do not redefine the builtins.
- Fix definition of internal_mem* functions with compilers that want the
  aliased function to already be defined before.
- Fix definition of __sanitizer_internal_mem* functions with compilers
  more pedantic about attribute placement around extern "C".

[mlir][transform] Utilize op interface instead of tensor::TrackingListener

Add a new interface `FindPayloadReplacementOpInterface` to specify ops that should be skipped when looking for payload replacement ops. Such ops are typically metadata-only ops.

With this change, we no longer need to maintain a custom TrackingListener in the tensor dialect.

Note: `CastOpInterface` by itself is not sufficient. Some metadata-only ops such as "tensor.reshape" are not casts, and it would be incorrect for them to implement the `CastOpInterface`.
