I sort of automaticly posted this to -committers... -------- Original Message -------- Subject: Rq for approval: new command: genassym Date: Wed, 22 Dec 1999 14:39:31 +0100 From: Marcel Moolenaar <marcel@scc.nl> Organization: SCC vof To: committers@freebsd.org Hi, Cross-building a kernel and modules (linux and svr4 in this case) is still not possible because the way assembler symbols are generated. The problem is basicly that we need to run a program built with the cross-compiler, which is not always possible. To solve this I made a genassym tool. It works as follows: A C source file (genassym.c for example) contains a number of data declarations of the form: int assym_MY_SYMBOL_NAME = SOME_VALUE; This file is compiled. The genassym tool reads the ELF object file and extracts the data declarations and creates the appropriate assembler declarations of the form: #define MY_SYMBOL_NAME SOME_VALUE A genassym tool is needed to be able to cross-build an i386 world on Alpha (for example) because the linux and svr4 modules won't build otherwise. Of course we also need this when we want to cross-build a kernel... The tool (incl. manpage) can be downloaded: http://www.freebsd.org/~marcel/genassyms.tar.gz Rewritten xxx_genassym.c source files for i386, alpha, linux module and svr4 module can be downloaded: http://www.freebsd.org/~marcel/assyms.tar.gz Q: Can I add the tool to src/usr.bin and eventually change the source files and Makefiles?
