Hi,
As part of my work with Elsa/LLVM I've been trying to wean myself from gcc, I'm using my own preprocessor now (to eliminate gcc -E) and have been calling ld and as directly. To do this, I've set up a version of bunutils (based on 2.18.50) and gdb/insight (based on 6.8) to handle all the LLVM targets (except PIC, see below).
The nice thing about gdb 6.8 is that one binary can deal with multiple (remote) targets. I've configured and built this package for the following targets:
alpha-elf
arm-elf
spu-elf
ia64-elf
nios2-elf
mips-elf
powerpc-elf
powerpc64-elf
sparc-elf
x86-elf
x86_64-elf
x86-pe
The nios2 support was added from the Altera port. I'm working on a Nios2 code generator for LLVM.
This package builds one assembler for each target, one gdb/insight for all, one linker for all, and the other binutils utilities supporting all processors.
If anyone is interested, you can grab the package with svn from
http://www.ellcc.org/svn/ellcc/trunk/gnu/
The is a shell script "makegnu" that should build the package for you.
This is very preliminary stuff. I've compiled programs for all the targets and assembled them. I've debugged programs on my linux host. I've linked programs for Linux.
My question is: What assembler does the LLVM PIC target use? I'd like to add it to my collection. I don't think gas supports the PIC in version 2.18.
For more (rough) information on ellcc, see http://ellcc.org, especially the wiki (http://www.ellcc.org/wiki/index.php/Main_Page).
