logging messages that are written the same, making it difficult to
know for certain which code path was taken based on a logfile. Add
some words to make each unique.
Right now the ordering for finding a FullUnwindPlan (ignoring
fallback unwind plan logic) is
1. If this is a _sigtramp like function, try eh_frame which is
hand written on darwin systems to account for finding the
saved register context correctly.
2. Ask the DynamicLoader if eh_frame should be preferred for
this frame. Some binaries on the system may have hand-written
eh_frame and the DynamicLoader is the source for this. (primarily
this is for hand-written assembly in the objc runtime, and we tell
lldb to trust that for functions in libobjc.dylib.)
3. if 0th frame, use GetUnwindPlanAtNonCallSite plan.
4. GetUnwindPlanAtCallSite {for 0th or any other}
5. GetUnwindPlanAtNonCallSite {now for non-0th frames, only if not from a compiler? hm.}
6. GetUnwindPlanArchitectureDefaultAtFunctionEntry if we're on the first instruction
7. Architectural default unwind plan ABI::CreateDefaultUnwindPlan
I'm moving triSYCL#6 -- DefaultAtFunctionEntry -- up to between triSYCL#3 and triSYCL#4,
where we're already doing things specific to the zeroth frame. If
we're on the zeroth frame and the GetUnwindPlanAtNonCallSite plan
has failed for some reason, and we're on the first instruction, we
should definitely use DefaultAtFunctionEntry instead of any other
unwind plan. If we're trying to step out of some rando function
on the system that we couldn't assembly instruction inspect, this
is sufficient for us to step out of it.

If a core file has an EFI version string which includes a UUID (similar to what it returns for the kdp KDP_KERNELVERSION packet) in the LC_IDENT or LC_NOTE 'kern ver str' load command. In that case, we should try to find the binary and dSYM for the UUID listed. The dSYM may have python code which knows how to relocate the binary to the correct address in lldb's target section load list and loads other ancillary binaries. The test case is a little involved, 1. it compiles an inferior hello world apple (a.out), 2. it compiles a program which can create a corefile manually with a specific binary's UUID encoded in it, 3. it gets the UUID of the a.out binary, 4. it creates a shell script, dsym-for-uuid.sh, which will return the full path to the a.out + a.out.dSYM when called with teh correct UUID, 5. it sets the LLDB_APPLE_DSYMFORUUID_EXECUTABLE env var before creating the lldb target, to point to this dsym-for-uuid.sh, 6. runs the create-corefile binary we compiled in step triSYCL#2, 7. loads the corefile from step triSYCL#6 into lldb, 8. verifies that lldb loaded a.out by reading the LC_NOTE load command from the corefile, calling dsym-for-uuid.sh with that UUID, got back the path to a.out and loaded it. whew! <rdar://problem/47562911> llvm-svn: 366378

…ned form
The DWARF spec says:
Any debugging information entry representing the declaration of an object,
module, subprogram or type may have DW_AT_decl_file, DW_AT_decl_line and
DW_AT_decl_column attributes, each of whose value is an unsigned integer
^^^^^^^^
constant.
If however, a producer happens to emit DW_AT_decl_file /
DW_AT_decl_line using a signed integer form, llvm-dwarfdump crashes,
like so:
(... snip ...)
0x000000b4: DW_TAG_structure_type

[with T = long unsigned int]: Assertion `hasVal' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.

Likewise with DW_AT_call_file / DW_AT_call_line.
The problem is that the code in llvm/lib/DebugInfo/DWARF/DWARFDie.cpp
dumping these attributes assumes that
FormValue.getAsUnsignedConstant() returns an armed optional. If in
debug mode, we get an assertion line the above. If in release mode,
and asserts are compiled out, then we proceed as if the optional had a
value, running into undefined behavior, printing whatever random
value.
Fix this by checking whether the optional returned by
FormValue.getAsUnsignedConstant() has a value, like done in other
places.
In addition, DWARFVerifier.cpp is validating DW_AT_call_file /
DW_AT_decl_file, but not AT_call_line / DW_AT_decl_line. This commit
fixes that too.
The llvm-dwarfdump/X86/verify_file_encoding.yaml testcase is extended
to cover these cases. Current llvm-dwarfdump crashes running the
newly-extended test.
"make check-llvm-tools-llvm-dwarfdump" shows no regressions, on x86-64
GNU/Linux.

For the following program,
$ cat t.c
struct t {
int (__attribute__((btf_type_tag("rcu"))) *f)();
int a;
};
int foo(struct t *arg) {
return arg->a;
}
Compiling with 'clang -g -O2 -S t.c' will cause a failure like below:
clang: /home/yhs/work/llvm-project/clang/lib/Sema/SemaType.cpp:6391: void {anonymous}::DeclaratorLocFiller::VisitParenTypeLoc(clang::ParenTypeLoc):
Assertion `Chunk.Kind == DeclaratorChunk::Paren' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
Stack dump:

......
The reason of the failure is due to the mismatch of TypeLoc and D.getTypeObject().Kind. For example,
the TypeLoc is
BTFTagAttributedType 0x88614e0 'int btf_type_tag(rcu)()' sugar
|-ParenType 0x8861480 'int ()' sugar
| `-FunctionNoProtoType 0x8861450 'int ()' cdecl
| `-BuiltinType 0x87fd500 'int'
while corresponding D.getTypeObject().Kind points to DeclaratorChunk::Paren, and
this will cause later assertion.
To fix the issue, similar to AttributedTypeLoc, let us skip BTFTagAttributedTypeLoc in
GetTypeSourceInfoForDeclarator().

However, even when the tests `PASS` with Solaris `ld`, `ASAN_OPTIONS=verbosity=2` shows ==6582==__tls_get_addr: Can't guess glibc version Given that that the code is stricly `glibc`-specific according to `sanitizer_tls_get_addr.h`, there seems little point in using the interceptor on non-`glibc` targets. That's what this patch does. Tested on `i386-pc-solaris2.11` and `sparc-sun-solaris2.11` inside the GCC tree. Differential Revision: https://reviews.llvm.org/D141385

Add build-bot and test support to the repository for Intel devices/tests to make sure pull requests are not breaking existing functionality. There should already be some functionality added for this that Intel added and use at the moment: https://github.com/triSYCL/sycl/tree/sycl/unified/master/buildbot
It would be nice to have FPGA compilation support for the build-bot tests, but it does not seem to be feasible as the compilation takes too long and the SDAccel package isn't an Ubuntu package (also the size of it would probably kill the Travis environment).
