Bug ID: 35621
Summary: Wasm data segment initialisers should omit zeros
Product: lld
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: All Bugs

When LLD creates Wasm output, it should compress the data by splitting the
memory initializer around runs of zeros, which are redundant. This should work
because the Memory starts off zero-initialised I believe? A large
zero-initialised array shouldn't take any space in the output file.
