Message-ID: <10788.940430901.0@NO-ID-FOUND.mhonarc.org> (raw)
Hello again:
This revision adds support for symbols that have their own unique
section, to allow
for gc by the linker when --gc-sections support for COFF is added.
ld/Changelog:
1999-10-19 Mark Elbrecht <snowball3@bigfoot.com>
* scripttempl/i386go32.sc (___EH_FRAME_BEGIN__): Delete.
(___EH_FRAME_END__): Delete.
(_etext, _end): Move the semicolon inside the brace.
* scripttempl/i386go32.sc: Support prioritized constructors
and destructors.
Support symbols that have their own unique section.
