Bug ID: 42544
Summary: Assertion `BB->getTerminator()->getNumSuccessors() ==
1 && "Should have a single succ!"' failed
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Transformation Utilities
Assignee: unassignedb...@nondot.org
Reporter: pe...@pcc.me.uk
CC: llvm-bugs@lists.llvm.org
With the following test case (reduced from an LTO build of the Linux kernel) I
get:
$ cat fair.i
enum {
a,
b
}
# 1 "" 3
c() {
asm goto("" : : : : d);
asm("");
return a;
d:
return b;
}
ag;
e(f) {
ag &&f;
_Bool am = c();
e(am);
}
$ clang -flto -O2 -c -o fair.o fair.i -fno-optimize-sibling-calls
$ ld.lld -r -o vmlinux.o fair.o
ld.lld: [...]/llvm/lib/Transforms/Utils/BasicBlockUtils.cpp:348:
llvm::BasicBlock *llvm::SplitEdge(llvm::BasicBlock *, llvm::BasicBlock *,
llvm::DominatorTree *, llvm::LoopInfo *, llvm::MemorySSAUpdater *): Assertion
`BB->getTerminator()->getNumSuccessors() == 1 && "Should have a single succ!"'
failed.
