Summary:
This allows unit tests for components that use Support/Debug.h to print
debug information from test runs by specifying -debug when running the
test.

// FIXME: Constraints are hard coded to 'm', but we need an 'r'
// constraint for addressof. This needs to be cleaned up!
Test cases are already in place. Specifically,
clang/test/CodeGen/ms-inline-asm.c t15(), t16(), and t24().

I give up trying to get all of the settings into COMMON_MAKEFLAGS, so just
do the easy thing and repeat the ones with interesting quoting issues
in each make command.

This change is basically just copying changes that we've used for Apple's
clang builds to the script used for building llvmCore. Besides cleaning it
up to use xcrun to locate the proper versions of tools, especially for cross
compiling, it fixes the build to work with newer versions of clang that
honor SDKROOT settings in the environment.

The purpose of this patch is to allow PredicateMethods to be set to something
like "isUImm<8>", calling a C++ template method to reduce code duplication. For
this to work, the PredicateMethod must be mangled into a valid C++ identifier
for insertion into an enum.
llvm-svn: 172073
When processing possible aliases, TableGen assumes that if an operand *can* be
an immediate, then it always *will* be. This is incorrect for the AArch64
backend. This patch inserts a check in the generated code to make sure isImm is
true first.
llvm-svn: 171972
This was an experimental option, but needs to be defined
per-target. e.g. PPC A2 needs to aggressively hide latency.
I converted some in-order scheduling tests to A2. Hal is working on
more test cases.

make into the last commit.
Also, update the test-generation script to generate an exhaustive test for
align_to_end as well, and include the generated test.
llvm-svn: 171811
* Add support for specifying the alignment to use.
* Add the concept of native endianness. Used for unaligned native types.
The native alignment and read/write simplification is based on a patch by Richard Smith.

Aside from moving the actual files, this patch only updates the build
system and the source file comments under lib/... that are relevant.
I'll be updating other docs and other files in smaller subsequnet
commits.
While I've tried to test this, but it is entirely possible that there
will still be some build system fallout.
Also, note that I've not changed the library name itself: libLLVMCore.a
is still the library name. I'd be interested in others' opinions about
whether we should rename this as well (I think we should, just not sure
what it might break)

the script generating it. The test should never be modified manually. If anyone
needs to change it, please change the script and re-run it.
The script is placed into utils/testgen - I couldn't think of a better place,
and after some discussion on IRC this looked like a logical location.

FYI, llvm and clang can be built deterministically between stage 2 and stage3, among iterative clean rebuilds, with GNU ar;
configure --disable-timestamps
make AR.Flags=crsD RANLIB=echo
llvm-svn: 170682
MC disassembler clients (LLDB) are interested in querying if an
instruction may affect control flow other than by virtue of being
an explicit branch instruction. For example, instructions which
write directly to the PC on some architectures.

beyond array bounds.
No test case since I cannot reproduce an ICE with this bug. According
to Carlos -- the bug reporter -- a segfault occurs only when LLVM is
compiled with a specific version of GCC.

- Use SOURCES instead of Source. See Makefile.rules and MakefileGuide.html.
- Don't assume the current directory. $(wildcard *.cc) doesn't match anything on corresponding build directory.
llvm-svn: 169568
1) don't delete gtest-all.cc (which is used to gather all gtest source
files in a single file)
2) make including LLVMSupport headers optional (on by default).
Sanitizer tools may want to use their own versions of googletest
compiled with specific flags, instead of the common googletest
library used for all other LLVM/Clang unittests.
llvm-svn: 169559
RUN: a
RUN: b || true
as "a && (b || true)" in Tcl mode, and as "(a && b) || true" in sh mode.
Everyone seems to (quite reasonably) write tests assuming the Tcl behavior,
so use that in sh mode too.
llvm-svn: 169441
This is much simpler to reason about, more efficient, and
fixes some corner cases involving implicit super-register defs.
Fixed rdar://12797931.
llvm-svn: 169425
At build-time register pressure was always computed in terms of
register units. But the compile-time API was expressed in terms of
register classes because it was intended for virtual registers (and
physical register units weren't yet used anywhere in codegen).
Now that the codegen uses physreg units consistently, prepare for
tracking register pressure also in terms of live units, not live
registers.

1) Teach it to handle files with #include on the first line -- these do
actually exist in LLVM.
2) Support llvm-c and clang-c include projects.
3) Nuke some stail imports.
4) Switch to using os.path to split the file extension off.
5) Remove debugging leftovers.
6) Add docstring (a really puny one) for the sort function.
I'm continuing te avoid stripping the whitespace on the RHS to preserve
whatever newline characters happen to be in the original file.

I am a terrible Python programmer. Patches more the welcome. Please tell
me how this should look if it should look differently. It's just a tiny
little script so it didn't make sense to go through pre-commit review,
especially as someone who actually knows python may want to just rip it
apart and do it The Right Way.
I will be preparing a commit shortly that uses this script to
canonicalize *all* of the #include lines in LLVM. Really, all of them.

; CHECK: [[VAR:[a-z]]]
The problem was that to find the end of the regex var definition, it was
simplistically looking for the next ]] and finding the incorrect one. A
better approach is to count nesting of brackets (taking escaping into
account). This way the brackets that are part of the regex can be discovered
and skipped properly, and the ]] ending is detected in the right place.
llvm-svn: 169109
When code deletes the context, the AttributeImpls that the AttrListPtr points to
are now invalid. Therefore, instead of keeping a separate managed static for the
AttrListPtrs that's reference counted, move it into the LLVMContext and delete
it when deleting the AttributeImpls.
llvm-svn: 168354
This patch replaces the hard coded GPR pair [R0, R1] of
Intrinsic:arm_ldrexd and [R2, R3] of Intrinsic:arm_strexd with
even/odd GPRPair reg class.
Similar to the lowering of atomic_64 operation.
llvm-svn: 168207
- Add RTM code generation support throught 3 X86 intrinsics:
xbegin()/xend() to start/end a transaction region, and xabort() to abort a
tranaction region

Explicitly allow composition of null sub-register indices, and handle
that common case in an inlinable stub.
Use a compressed table implementation instead of the previous nested
switches which generated pretty bad code.
llvm-svn: 167190
Most places can use PrintFatalError as the unwinding mechanism was not
used for anything other than printing the error. The single exception
was CodeGenDAGPatterns.cpp, where intermediate errors during type
resolution were ignored to simplify incremental platform development.
This use is replaced by an error flag in TreePattern and bailout earlier
in various places if it is set.
llvm-svn: 166712
Relationship maps are represented as InstrMapping records which are parsed by
TableGen and the information is used to construct mapping tables to represent
appropriate relations between instructions. These tables are emitted into
XXXGenInstrInfo.inc file along with the functions to query them.
Patch by Jyotsna Verma <jverma@codeaurora.org>.
llvm-svn: 166685
- The XTARGET feature (inherited from old DG tests) was just confusing (and
barely ever used). The same effect can now be achieved with a combination of
the more useful REQUIRES and XFAIL.
llvm-svn: 166305
Convert the internal representation of the Attributes class into a pointer to an
opaque object that's uniqued by and stored in the LLVMContext object. The
Attributes class then becomes a thin wrapper around this opaque
object. Eventually, the internal representation will be expanded to include
attributes that represent code generation options, etc.
llvm-svn: 165917
Some of these dyn_cast<>'s would be better phrased as isa<> or cast<>.
That will happen in a future patch.
There are also two dyn_cast_or_null<>'s slipped in instead of
dyn_cast<>'s, since they were causing crashes with just dyn_cast<>.
llvm-svn: 165646
This is a mechanical change of dynamic_cast<> to dyn_cast<>. A number of
these uses are actually more like isa<> or cast<>, and will be changed
to the semanticaly appropriate one in a future patch.
llvm-svn: 165291
This allows the processor-specific machine model to override selected
base opcodes without any fanciness.
e.g. InstRW<[CoreXWriteVANDP], (instregex "VANDP")>.
llvm-svn: 165180
A processor can now arbitrarily alias one SchedWrite onto
another. Only the SchedAlias definition need be within the processor
model. The aliased SchedWrite may be a SchedVariant, WriteSequence, or
transitively refer to another alias.
llvm-svn: 165179
map constraints and MCInst operands to inline asm operands. This replaces the
getMCInstOperandNum() function.
The logic to determine the constraints are not in place, so we still default to
a register constraint (i.e., "r"). Also, we no longer build the MCInst but
rather return just the opcode to get the MCInstrDesc.
llvm-svn: 164979
This is a generally useful utility; there's no reason to have it hidden
in CodeGenDAGPatterns.cpp.
Also, rename it to fit the other comparators in Record.h

Now where we used to call ReInitMCSubtargetInfo, we actually recompute
the same information as InitMCSubtargetInfo instead of only setting
the feature bits.
