[llvm-dev] Assertion triggered when running simple hello-world code on iOS device using ORC/LLLazyJIT

FWIW - found out LLVM does produce zero length sections if you use
function sections (or have an inline function) for functions like
this:

int f1() { } // at -O0 that'll include a trap instruction, above that
it'll be completely empty/zero-length
void f2() { __builtin_unreachable(); } // similar I Think - though
maybe it's zero length even at -O0 (llvm_unreachable then adds the
-O0-checking behavior on top, perhaps)

-- I'm afraid this got buried. I see from the output that the text section
contains a single block of zero size. I have not encountered this before in my
test cases, but it is perfectly legal -- I see no problem with the input object
itself. It tripped that assertion in JITLink because the assertion required
symbols to start before the end of the block, which is impossible in an empty
block. I've relaxed that assertion in 22d7a01dd72 to require that symbols
end on or before the end of their blocks. This allows for the possibility of
zero-sized symbols at the end of blocks (and at the start of empty blocks).

[llvm-dev] Assertion triggered when running simple hello-world code on iOS device using ORC/LLLazyJIT

Hi Dave,

Yep. This is JITLink specific, so we could only have observed it on MachO
x86-64 or arm64 until recently. It takes a little bit of poking to get IR
to produce a zero-lengh section on MachO, but not much.

Jared Wyles recently contributed an initial JITLink ELF implementation, so
the fix seems timely -- we might have been about to see more of it.

-- Lang.

[llvm-dev] Assertion triggered when running simple hello-world code on iOS device using ORC/LLLazyJIT

Ah, fair enough -presumably if you had one of those empty functions as
the only function in a module you'd get this, then? (& ORC likes small
modules, so maybe not too much of a stretch to get such a situation)

Out of curiosity - what'd it take?

delayed reply -- I'm afraid this got buried. I see from the output that the
text section contains a single block of zero size. I have not encountered this
before in my test cases, but it is perfectly legal -- I see no problem with the
input object itself. It tripped that assertion in JITLink because the assertion
required symbols to start before the end of the block, which is impossible in an
empty block. I've relaxed that assertion in 22d7a01dd72 to require that
symbols end on or before the end of their blocks. This allows for the
possibility of zero-sized symbols at the end of blocks (and at the start of
empty blocks).
