Using gcc version 4.3.0 20080125 (experimental) (GCC) to crosscompile the
attached file for m68k-elf, I get the following line of asm:
move.l (%a2,%a0.l*4),76(%sp)
which is invalid for the target cpu I have specified. (-mcpu=5249)
This is my compiler command line:
/rockbox/apps/codecs/Tremor$ /usr/bin/ccache m68k-elf-gcc
-I/home/nils/rockbox/apps -I.. -I. -I/home/nils/rockbox/firmware/include
-I/home/nils/rockbox/firmware/export -I/home/nils/rockbox/firmware/common
-I/home/nils/rockbox/firmware/drivers -I/home/nils/rockbox/gcctest
-I/home/nils/rockbox/apps/recorder -I/home/nils/rockbox/apps/gui -W -Wall
-Wundef -Os -nostdlib -ffreestanding -Wstrict-prototypes -mcpu=5249 -malign-int
-mstrict-align -fomit-frame-pointer
-I/home/nils/rockbox/firmware/target/coldfire/iriver/h300
-I/home/nils/rockbox/firmware/target/coldfire/iriver
-I/home/nils/rockbox/firmware/target/coldfire -O2 -DIRIVER_H300 -DMEM=32
-save-temps block.c -o /home/nils/rockbox/gcctest/apps/codecs/Tremor/block.o
I used the following switches to configure gcc:
--target=m68k-elf --prefix=/usr/local/m68k-elf --enable-languages=c
--disable-libssp --with-arch=cf
on my amd64 linux system

------- Comment #2 from schwab at suse dot de 2008-02-14 17:35 -------
The problem is in the addsi_lshrsi_31 insn:
(define_insn "addsi_lshrsi_31"
[(set (match_operand:SI 0 "nonimmediate_operand" "=dm")
(plus:SI (lshiftrt:SI (match_operand:SI 1 "general_operand" "rm")
(const_int 31))
(match_dup 1)))]
""
{
operands[2] = operands[0];
operands[3] = gen_label_rtx();
if (GET_CODE (operands[0]) == MEM)
{
if (GET_CODE (XEXP (operands[0], 0)) == POST_INC)
operands[0] = gen_rtx_MEM (SImode, XEXP (XEXP (operands[0], 0), 0));
else if (GET_CODE (XEXP (operands[0], 0)) == PRE_DEC)
operands[2] = gen_rtx_MEM (SImode, XEXP (XEXP (operands[0], 0), 0));
}
output_asm_insn ("move%.l %1,%0", operands);
The constraints are wrong for coldfire.

This is fixed only on trunk; 4.3 still has the bug. Do you think it's
appropriate to close it anyway?

Fixed long ago. Holding it open because the patch wasnt' backported to an old
branch is rather silly.
