Please reopen this bug. It's still present on current 3.3-branch:
printf.c:2451: error: insn does not satisfy its constraints:
(insn 1379 542 543 38 (nil) (set (reg:QI 8 %a0)
(mem:QI (plus:SI (reg/f:SI 14 %a6)
(const_int -209 [0xffffff2f])) [0 mode S1 A8])) 37
{*m68k.md:1060} (nil)
(nil))
I can't reproduce it on 3.4, but it's probably latent,
not really fixed.

Please reopen this bug for 3.4.0. The summary should read
something like "movqi operand constraints too restrictive
for TARGET_COLDFIRE"
This ICE resurfaced on m68k-uclinux in in the 20030114
snapshot from mainline. It wasn't present in the previous
snapshot (20030107).
m68k-uclinux-gcc -Wall -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing
-Os -Wa,--bitwise-or -I/usr/local/src/uclinux-tools/linux-2.6.x/include -m5200
-msoft-float -fno-builtin -nostdinc -D_LIBC -I../../include -I.
-I/usr/local/lib/gcc/m68k-uclinux/3.4.0/include -DNDEBUG -DL__fpmaxtostr
printf.c -c -o _fpmaxtostr.o
printf.c: In function `_fpmaxtostr':
printf.c:2454: error: insn does not satisfy its constraints:
(insn 1378 536 537 38 (set (reg:QI 8 %a0)
(mem:QI (plus:SI (reg/f:SI 14 %a6)
(const_int -209 [0xffffff2f])) [0 mode+0 S1 A8])) 33
{*m68k.md:825} (nil)
(nil))
printf.c:2454: internal compiler error: in reload_cse_simplify_operands, at
postreload.c:378
This is the offending pattern:
(define_expand "movqi"
[(set (match_operand:QI 0 "nonimmediate_operand" "")
(match_operand:QI 1 "general_src_operand" ""))]
""
"")
(define_insn ""
[(set (match_operand:QI 0 "nonimmediate_operand" "=d,*a,m")
(match_operand:QI 1 "general_src_operand" "dmSi*a,di*a,dmSi"))]
"!TARGET_COLDFIRE"
"* return output_move_qimode (operands);")
(define_insn ""
[(set (match_operand:QI 0 "nonimmediate_operand" "=d<Q>,dm,d*a")
(match_operand:QI 1 "general_src_operand" "dmi,d<Q>,di*a"))]
"TARGET_COLDFIRE"
"* return output_move_qimode (operands);")
The problem has been discussed here:

This is a dup of bug 13803.
