The CL kernel
The attached source makes clang (6.0-rc1 and trunk) assert on
cast<BlockExpr>().
I tried ignoring the ExprWithCleanups:
if (auto DR = dyn_cast<DeclRefExpr>(E)) {
E = cast<VarDecl>(DR->getDecl())->getInit();
}
+ if (auto Cast = dyn_cast<ExprWithCleanups>(E)) {
+ E = Cast->getSubExpr();
+ }
if (auto Cast = dyn_cast<CastExpr>(E)) {
E = Cast->getSubExpr();
}
auto *Block = cast<BlockExpr>(E);
but it seems like clang also tries to emit the same block expression twice (the
second time through the OCL enqueue specific codepath.)
Options I used for clang: "-x cl -cl-std=CL2.0 enqueue_block_kernel.cl"</pre>
