Bug ID: 27688 Summary: gas does not support .secidx pseudo-directive Product: binutils Version: unspecified Status: UNCONFIRMED Severity: normal Priority: P2 Component: gas Assignee: unassigned at sourceware dot org Reporter: mark at harmstone dot com Target Milestone: --- Created attachment 13345 --> https://sourceware.org/bugzilla/attachment.cgi?id=13345&action=edit secidx patch llvm-mc has a pseudo-directive .secidx for COFF files, which maps to a IMAGE_REL_I386_SECTION / IMAGE_REL_AMD64_SECTION relocation entry. This is a two-byte field which gets set to the section index of a label when it's linked. This is necessary for support for CodeView / PDB debugging, as addresses are represented by a two-byte section index and a four-byte offset (i.e. a .secidx and a .secrel32). See also my CodeView patches to the gcc mailing list, which rely on this to work. I've attached a patch, which implements this for x86 and amd64. -- You are receiving this mail because: You are on the CC list for the bug.
