Minimised test case
The attached code crashes llvm when building at least for arm.
I'm using the following to build:
/home/at718/obj/arm.arm/home/at718/freebsd/tmp/usr/bin/cc -cc1 -triple
armv4t--freebsd11.0-gnueabi -emit-obj -debug-info-kind=standalone -O2 -x c
parser-a642a1.c
I'm getting this error:
Assertion failed: (Offset <= PieceOffset && "overlapping or duplicate pieces"),
function finalize, file
/home/at718/freebsd/lib/clang/libllvmasmprinter/../../../contrib/llvm/lib/CodeGen/AsmPrinter/DwarfDebug.cpp,
line 1561.
The trace looks like:
