LLD bug causing objcopy ELF to binary generation to create large binaries
Hi LLVM devs,
I came across an LLD bug in v 10.x where ELF parser / processor is
setting .PROGBITS attribute for .heap and .stack sections, which leads
to large binaries when we do `llvm-objcopy -o binary` to generate the
binary output for armv6m. (e.g. for a 57Kb elf would yield a ~400Mb
binary).
This in comparison with LLVM 7.x , would produce the correct binary size
of 35Kb and the
