Bug ID: 33064
Summary: Merge IAT and ILT
Product: lld
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: COFF
Assignee: unassignedbugs at nondot.org
Reporter: ruiu at google.com
CC: llvm-bugs at lists.llvm.org
Currently, LLD-produced executables have IAT (Import Address Table) and ILT
(Import Lookup Table) as separate chunks of data, although their contents are
identical. My interpretation of the COFF spec when I wrote the COFF linker is
that they need to be separate tables even though they are the same.
But Peter found that the Windows loader is fine with executables in which IAT
and ILT are merged.
We should merge them to save space.
