I'm trying to use ocamlopt to generate binary executables for a machine
built upon DEC Alpha (21066) processors.
Cross-compilation is done on a Sun Ultra under Solaris.
As explained by X. Leroy in a recent mail, i've edited the config/Makefile
to use my specific cross-compiler/assembler and patched the name of
the assembler in the relevant files.
I have some problems with the assembly code given in asmrun/alpha.S and
generated when compiling stdlib/*.ml. For example:
alpha.S:151: Warning: Illegal operands
(* line 151 is: jsr garbage_collection *)
alpha.S:238: Warning: Illegal operands
(* line 238 is: jsr ($25) *)
/tmp/camlasm9.s:1200: Error: Unknown opcode: `ldbu'
(* when compiling stdlib/pervasives.ml, line 577 is: ldbu $2, 0($3) *)
The cross-assembler is a bundled derivative of GNU as (verbose option gives:
GNU assembler version 2.6 (alpha-dec-netbsd10), using BFD version 2.6)
and i could not find any information on the Alpha assembly language in the
GNU as doc.
I was therefore wondering if someone who has played with the Alpha could give
me any hint..
