Bug ID: 38749
Summary: [Linker script] forward reference
Product: lld
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: ELF
Assignee: [email protected]

Can lld support forward reference to a section which is mentioned after?
At line 4, _text_start refers to .bss which is specified after and expected
value is 0x4000.
This feature is supported by bfd linker.
