7 years agoELF core: Adding parsing of the floating-point and SSE registers on x86 32/64 bit...
Dimitar Vlahovski [Sun, 20 Nov 2016 21:24:49 +0000 (21:24 +0000)]
ELF core: Adding parsing of the floating-point and SSE registers on x86 32/64 bit elf core files

Summary:
The floating-point and SSE registers could be present in the elf-core
file in the note NT_FPREGSET for 64 bit ones, and in the note
NT_PRXFPREG for 32 bit ones.

The entire note is a binary blob matching the layout of the x87 save
area that gets generated by the FXSAVE instruction (see Intel developers
manual for more information).

This CL mainly modifies the RegisterRead function in
RegisterContextPOSIXCore_x86_64 for it to return the correct data both
for GPR and FPR/SSE registers, and return false (meaning "this register
is not available") for other registers.

I added a test to TestElfCore.py that tests reading FPR/SSE registers
both from a 32 and 64 bit elf-core file and I have inluded the source
which I used to generate the core files.

I tried to also add support for the AVX registers, because this info could
also be present in the elf-core file (note NT_X86_XSTATE - that is the result of
the newer XSAVE instruction). Parsing the contents from the file is
easy. The problem is that the ymm registers are split into two halves
and they are in different places in the note. For making this work one
would either make a "hacky" approach, because there won't be
any other way with the current state of the register contexts - they
assume that "this register is of size N and at offset M" and
don't have the notion of discontinuos registers.

When building in a mingw environment, we need to provide them somehow,
e.g. via compiler-rt.

The aeabi divmod functions work in the same way as the corresponding
__rt_*div* functions for windows, but their parameters are swapped.
The functions for converting float to integer and vice versa are the
same as their aeabi equivalents, only with different function names.

Mehdi Amini [Sat, 19 Nov 2016 18:44:16 +0000 (18:44 +0000)]
[ThinLTO] Fix crash when importing an opaque type

It seems that because ThinLTO does not import the full module,
some invariant of the type mapper are broken.

In Monolithic LTO, we import every globals: when calling
IRLinker::copyFunctionProto() on @foo(), we end-up calling
TypeMapTy::get(FTy) on the type of @foo(), which will map
%0 and record the destination as opaque.

ThinLTO skips this because @foo is not imported and goes directly
to the next stage.

Next we call computeTypeMapping() that map the types for each
globals, and ends up checking for type isomorphism, and may add
type mapping. However it doesn't record if there was an opaque
destination type that was resolved.

Instead of lazily "discovering" opaque type in the destination
module on the go, we change the TypeFinder to eagerly record all
types and not only the named ones.

[libcxx] Implement locale.h to fix modules build

Summary:
Because `locale.h` isn't part of the libc++ modules the class definitions it provides are exported as part of `__locale` (since it happens to be build first). This breaks `<clocale>` which exports `std::lconv` without including `<__locale>`.

This patch implements `locale.h` to fix this issue, it also adds support for testing libc++ with modules.

7 years ago[Sema] Don't allow applying address-of operator to a call to a function
Akira Hatanaka [Sat, 19 Nov 2016 00:13:03 +0000 (00:13 +0000)]
[Sema] Don't allow applying address-of operator to a call to a function
with __unknown_anytype return type.

When the following code is compiled, Sema infers that the type of
__unknown_anytype is double:

extern __unknown_anytype func();
double *d = (double*)&func();

This triggers an assert in CodeGenFunction::EmitCallExprLValue because
it doesn't expect to see a call to a function with a non-reference
scalar return type.

This commit prevents the assert by making VisitUnaryAddrOf error out if
the address-of operator is applied to a call to a function with
__unknown_anytype return type.
