It was assuming various things about the PDB like file size
which are going to be too high maintenance to maintain in
a test.

Previously we did not have support for writing detailed
module information for each module, as well as the symbol
records.  This patch adds support for this, and in doing
so enables the ability to construct minimal PDBs from
just a few lines of YAML.  A test is added to illustrate
this functionality.

llvm-svn: 297900

Introduce ScopStmt::getSurroundingLoop() to replace getFirstNonBoxedLoopFor.

getSurroundingLoop() returns the precomputed surrounding/first non-boxed
loop. Except in ScopDetection, the list of boxed loops is only used to
get the surrounding loop. getFirstNonBoxedLoopFor also requires LoopInfo
at every use which is not necessarily available everywhere where we may
want to use it.

This patch adds profile run time support to profile a range of values.
This interface will be used in profiling the size of memory intrinsic calls.

Currently the two flags can not work together.

To illustrate the issue, we can have an one line file a.cl contains only an empty function

cat a.cl

void test(){}

Then use

clang -v -save-temps -x cl -Xclang -cl-std=CL2.0 -Xclang -finclude-default-header -target amdgcn -S -c a.cl

we will get redefinition errors for various things.

The reason is that the -finclude-default-header flag is not meant to be on cc1 command other than the preprocessor.

The fix is modeled after the code just below the change to filter the -finclude-default-header flag out when we are not in the preprocess phase.

Together, these allow lldb-pdbdump to list all the modules from a PDB using a
native reader (rather than DIA).

Note that I'll probably be specializing NativeRawSymbol in a subsequent patch.

Prep work for PR31810

llvm-svn: 297876

Currently, we create a G_CONSTANT for every "synthetic" integer
constant operand (for instance, for the G_GEP offset).
Instead, share the G_CONSTANTs we might have created by going through
the ValueToVReg machinery.

When we're emitting synthetic constants, we do need to get Constants from
the context.  One could argue that we shouldn't modify the context at
all (for instance, this means that we're going to use a tad more memory
if the constant wasn't used elsewhere), but constants are mostly
harmless.  We currently do this for extractvalue and all.

For constant fcmp, this does mean we'll emit an extra COPY, which is not
necessarily more optimal than an extra materialized constant.
But that preserves the current intended design of uniqued G_CONSTANTs,
and the rematerialization problem exists elsewhere and should be
resolved with a single coherent solution.

We're now able to select ADDWri thanks to the new complex pattern

computeKnownBits didn't handle fp_to_fp16 to report
the high bits as 0. ARM maps the generic node to an instruction
that does not modify the high bits of the register, so introduce
a target node where the high bits are known 0.

If we got unlucky with register allocation and actual constpool placement, we
could end up producing a tTBB_JT with an index that's already been clobbered.

Technically, we might be able to fix this situation up with a MOV, but I think
the constant islands pass is complex enough without having to deal with more
weird edge-cases.
