In C++, constants captured by lambdas (and blocks) are not actually stored
in the closure object, since they can be expanded at compile time. In this
case, they will have no binding when we go to look them up. Previously,
RegionStore thought they were uninitialized stack variables; now, it checks
to see if they are a constant we know how to evaluate, using the same logic
as r175026.
This particular code path is only for scalar variables. Constant arrays and
structs are still unfortunately unhandled; we'll need a stronger solution
for those.
This may have a small performance impact, but only for truly-undefined
local variables, captures in a non-inlined block, and non-constant globals.
Even then, in the non-constant case we're only doing a quick type check.

The important fix is that the constant interpolation value is stored in the
parameter slot P0, which is encoded as 2.
In addition, drop the SI_INTERP_CONST pseudo instruction, pass the parameter
slot as an operand to V_INTERP_MOV_F32 instead of hardcoding it there, and
add a special operand class for the parameter slots for type checking and
pretty printing.
NOTE: This is a candidate for the Mesa stable branch.

validateSymbol() is called all over the place, and it seems it's a debug check.
It significantly speedups llvm-symbolizer used in tsan/asan/msan. validateSymbol() is the second hot function and accounts for 15% of runtime.

CMake and autotools disagree on what "host" means in a cross-compilation
context. Autotools (and lit) take it to be the machine the binaries being
compiled now will run on. CMake takes it to be the machine actually compiling
the binaries now.
This change makes lit.site-cfg more consistent between autotools and CMake,
allowing lit tests (particularly in ExecutionEngine) to run correctly when
cross-compiled with CMake

If vector types have legal register classes, then LLVM bypasses LegalizeTypes
on them, which causes faults currently since the code to handle them isn't in
place.
This fixes test failures when AArch64 is the default target.

Before:
aaaaaaaaaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa()
.aaaaaaaaaaaaaaaaa());
After:
aaaaaaaaaaaaaaaaaaaaaaaaa(

Not sure which of the formattings above is better, but we should not pick
one by accident.

So far, clang-format has always assumed the whitespace belonging to the
subsequent token. This has the negative side-effect that when
clang-format formats a line, it does not remove its trailing whitespace,
as it belongs to the next token.
Thus, this patch fixes most of llvm.org/PR15062.
We are not zapping a file's trailing whitespace so far, as this does not
belong to any token we see during formatting. We need to fix this in a
subsequent patch.
llvm-svn: 175152
The formatter can now format:
void aaaaaaaaaaaaaaaaaa(int level,
double *min_x,
double *max_x,
double *min_y,
double *max_y,
double *min_z,
double *max_z, ) {
}
Although this is invalid code, it frequently happens during development and
clang-format should be nicer :-).
