This patch removes all these newlines and just prints the compiler flags in one line as you see in the command line:
```

By moving the standalone check into the main CMake file, the whole file
is ignored in a regular (non-standalone) build. This means that you can
make changes to LLDBStandalone.cmake without having to reconfigure a
build in a different directory. This matters when you share one source
repository with different build directories (e.g. release-assert, debug,
standalone).

This follows the RFC <http://lists.llvm.org/pipermail/llvm-dev/2019-July/133724.html>.
Follow-on commits will add appropriate release notes changes etc.
Pushing this now and in a minimal form so there is reasonable time before 9.0
branches to resolve any issues arising from e.g. the backend being exposed on
different sanitizer setups.
The current builder for RISC-V is on the staging build-bot
<http://lab.llvm.org:8014/builders/llvm-riscv-linux>, however with the RISCV
backend being built by default it won't provide any real additional coverage.
We will shortly set up a builder that runs the test-suite in qemu-user.
llvm-svn: 366331
The original behavior was to always emit the offsets to each call site in the
call site table as uleb128 values, however on some architectures (eg RISCV)
these uleb128 offsets into the code cannot always be resolved until link time
(because relaxation will invalidate any calculated offsets), and there are no
appropriate relocations for uleb128 values. As a consequence it needs to be
possible to specify an alternative.
This also switches RISCV to use DW_EH_PE_udata4 for call side encodings in
.gcc_except_table

These intrinsics do in fact work with non-constant index arguments.
These are lowered to either the generic
ISD::INSERT_VECTOR_ELT/ISD::EXTRACT_VECTOR_ELT, or to
VEXTRACT_SEXT_ELT. The handling of these all accept variable
indexes. Turning these into generic instructions which do allow
variables introduces complications in a future change to immarg
handling.
Since these just turn into generic instructions, these are kind of
pointless and should probably just be autoupgraded to
extractelement/insertelement.
llvm-svn: 366328
This patch sets correct encodings for DWARF exception handling for RISC-V
(other than call site encoding, which must be udata4 rather than uleb128 and
is handled by D63415).
This has the same intend as D63409, except this version matches GCC/binutils
behaviour which uses the same encodings regardless of PIC/non-PIC and
medlow/medany code model.
llvm-svn: 366327
Summary:
With LLDB we use localUncachedLookup(), however, that fails to find
Decls when a transparent context is involved and the given DC has
external lexical storage. The solution is to use noload_lookup, which
works well with transparent contexts. But, we cannot use only the
noload_lookup since the slow case of localUncachedLookup is still needed
in some other cases.
These other cases are handled in ASTImporterLookupTable, but we cannot
use that with LLDB since that traverses through the AST which initiates
the load of external decls again via DC::decls().
We must avoid loading external decls during the import becuase
ExternalASTSource is implemented with ASTImporter, so external loads
during import results in uncontrolled and faulty import.

Summary:
Missed in the original commit, use the correct callee-saved register
list for spilling, instead of the standard SVR432 list. This avoids

As part of this, also add where missing, and sort, the spill opcode
checks for SPE and SPE4 register classes.

Summary:
Pointed out in a comment for D49754, register spilling will currently
spill SPE registers at almost any offset. However, the instructions
`evstdd` and `evldd` require a) 8-byte alignment, and b) a limit of 256
(unsigned) bytes from the base register, as the offset must fix into a
5-bit offset, which ranges from 0-31 (indexed in double-words).
The update to the register spill test is taken partially from the test
case shown in D49754.
Additionally, pointed out by Kei Thomsen, globals will currently use
evldd/evstdd, though the offset isn't known at compile time, so may
exceed the 8-bit (unsigned) offset permitted. This fixes that as well,
by forcing it to always use evlddx/evstddx when accessing globals.
