[Tinycc-devel] Hello!

[Jakob Bornecrantz]

Hello everybody!

I and a friend is trying to add support in TinyCC for the dcpu[1, 2],
we have gotten a little bit on the way and are able to emit function
prologe and math arithmetics.

We are currently using "-Wl,-format=binary" and "-c" to get out binary
data from it and have hacked in assembler output as well.

When I try without the "-c" flag I see it trying to link to crt1.o and
crti.o as well as a couple of standard libraries afterwards.

I'm wondering if it is possible to only get it to link with only
crt1.o and no standard library and then hack it to make _start be
located at 0x0 as a way to just get something slightly more proper and
that supports multiple C files?

Without -Wl,-format=binary it also looks like its outputting i386-efl
object file?

I'm guessing here but it looks like I should be able to write a
crt1.c[3] and compile that into a "i386-elf" and finally make the
linker output a binary.

I'm sorry if this email is a bit over the place. Thanks for any advice
you can give.

Cheers, Jakob.
