Use makeoptions_COPY_SYMTAB via opt_copy_symtab.h in sources. Remove a hack to set -DCOPY_SYMTAB from sys/conf/Makefile.kern.inc. Remove unnecessary dependencies too. 2015-08-30 04:46:02 +03:00			`/* $NetBSD: kern_ksyms_buf.c,v 1.4 2015/08/30 01:46:02 uebayasi Exp $ */`

Reorganize symbol table embedding. The existing option SYMTAB_SPACE is replaced by the make option COPY_SYMTAB set to any value. The copy of the symbol table is no longer put into a buffer in kern_ksyms.o, but a small helper object. This object is build first with a dummy size, then the kernel is linked to compute the real dimension of the symbol table buffer. After that, the helper object is rebuild and the kernel linked again. 2014-08-18 01:17:43 +04:00			`#define SYMTAB_FILLER "\|This is the symbol table!"`

Backout previous, Nick has a fix for binutils. 2015-05-08 12:43:41 +03:00			`char db_symtab[SYMTAB_SPACE] = SYMTAB_FILLER;`
