GCC 4.0.0pre bootstraps fine with both patched 2.15 and 2.16pre.

My understanding is that objcopy has far less knowledge about the ELF format
than readelf, and in particular about section group like item #3.

mpiler and the SunPro C compiler are supposed to be 100% binary
compatible (at least we strive for that on the GNU side), so GNU Binutils is
very likely compatible with the SunPro C compiler as a by-product. That's
not the case for the C++ compilers.

t. The
relocations should have been R_SPARC_UA32 for Sun ld to be able to grok
them. The bottom line is that you need GNU ld if you want to directly
use -gdwarf2 with GNU as (or use -g on an assembly file with GCC).

That indeed appears to be the most appropriate solution and would match what
GCC emits for its own DWARF-2 debug info (i.e. .uaword instead of .word
directives). Perhaps Jakub can give some insights.

Still with 2.16.1? Take a look at the ld/ld.log file and post one of the

GNU make?

Binutils 2.16.1 works fine for me on SPARC/Solaris 2.5.1, 2.6, 7, 8, 9.
With Solaris 10 your mileage may vary.

It's not Linux, it's Solaris, FreeBSD, QNX, Interix... you name it.
it, the current definition of R_386_PC32 is
the right one.

Again, it's not Linux, the i386 ABI predates Linux, Linux only conformed to
symbol from the current contents of the CPU eip register. Are
> you saying ABI contradicts that?
Yes, it's not the formula of R_386_PC32. Read the docs on the Sun site.

You're rewriting history, ELF was invented by UNIX System Laboratories.

You did respond twice to the same message, I didn't. :-)
Anyway, we all seem to agree that Sun doesn't "own" ELF.

Are you using GNU make? If not, I'd try with it.
