``` createFiles(args) readDefsym readerLinkerScript(*mb) ... readMemory readMemoryAssignment("ORIGIN", "org", "o") // eagerly evaluated target = getTarget(); link(args) writeResult<ELFT>() ... finalizeSections() script->processSymbolAssignments() addSymbol(cmd) // with this patch, evaluated here ``` readMemoryAssignment eagerly evaluates ORIGIN/LENGTH and returns an uint64_t. This patch postpones the evaluation to make * --defsym and symbol assignments * `CONSTANT(COMMONPAGESIZE)` (requires a non-null `lld:🧝:target`) work. If the expression somehow requires interaction with memory regions, the circular dependency may cause the expression to evaluate to a strange value.

Benchmarking
In order to make sure various developers can evaluate patches over the same tests, we create a collection of self contained programs.
